Using 2 monitors. Instructions for connecting two monitors to a computer

Very convenient to use two monitors(or monitor and TV set)on one computer, because the area of ​​the desktop is doubled, which means that the amount of information simultaneously displayed on the screens of two monitors also becomes larger. Looking over a static information field is more effective for the eyes. And if you open two program windows or two folders on one monitor, they will overlap each other, and if there are three windows or more, then it becomes completely inconvenient to go through these windows. On two monitors - a computer monitor and a projector, having two desktops, it is much more convenient and practical to work.

Computer setup with two monitors connected at the same time (when each monitor is connected to a separate output of the video card) for convenient control and switching between monitors is easier to do

  • through such programs , very user-friendly interface
  • and file shortcut display switch located on the quick launch bar,

The path to this file is (C:\Windows\SysWOW32\DisplaySwitch.exe), for win7

In order not to open this window- RMB(click right click mouse) on the desktop -> Screen resolution-> window Monitor setup(if you have 2 monitors):

or do not press win + P on the keyboard, find the DisplaySwitch.exe file, on Windows 7, 8 Displayswitch is located in the C:\Windows\SysWOW64 folder; on Windows XP, it can be found by searching the Windows folder.

right click on DisplaySwitch − icon to switch between two monitors and select the “pin to taskbar” item and you can turn on and off the non-main projector monitor with two right-clicks (in the picture it is indicated by an arrow):

click on it with the mouse - and the window for selecting the monitor operation mode will open, just like when you press it on the keyboard win+P:



Now one mouse click replaces many unnecessary and redundant actions. Mode selection:
only computer;
duplicate;
expand;
projector only - will be produced from this label.

For example, for two monitors it is possible to select different mode wallpaper and customize wallpaper: 1 - on this desktop; 2 - for each monitor separately; set a time to change pictures

In this DisplayFusion program window, you can set these options −

Here are the wallpapers on 2 monitors 3360 x 1050px







If as home computer you are using a laptop that has a monitor output, and there is no image on the connected monitor, then for it to work, you need to install latest version your video card drivers.

Using DisplayFusion working on two monitors is much easier! With powerful features such as Multi-Monitor Taskbars, TitleBar Buttons and fully customizable hotkeys, DisplayFusion makes managing multiple monitors a breeze. And with the help of an applet display switch switching between monitors, as well as turning them on or off, can be performed with only two mouse clicks, and having wireless mouse this can be done without going to the computer desk.

Connecting two or more monitors to a PC is an urgent need in a variety of areas. You can create such a system at home.

Connecting one or more monitors to a PC is not difficult. Following the step-by-step instructions, you will quickly make the connection. This will make the use of PC resources more comfortable.

If you think that two monitors connected to one computer is an extra option that has no practical application, then you are mistaken. This feature can be very useful in the following situations:

  1. If you need to organize a presentation in a conference room. The picture from the main computer is transmitted in real time to all monitors connected to it. Working this way saves time and money. In addition, the display can be used as the main monitor. mobile device(tablet or smartphone), that is, the system unit is not needed at all.
  2. If the user activates many windows during work and there is no desire to constantly switch between them, you can simply stretch the desktop over two monitors, which is very convenient in some cases:
    • This function is often used by office workers, where the presence of two monitors helps to save time;
    • Representatives creative professions(artists, composers) who need multiple monitors;
    • For processing statistical data, when you do not need to switch endlessly to compare data in several tables.
    • On several screens it is much more convenient to study large drawings, to consider small details.
  3. Two monitors are simply indispensable in the gaming field. Players often think about how to connect two monitors to one computer, because it would be simply impossible to organize multiplayer shooting games on one screen. In addition, high-resolution plasma screens can be connected for gaming. The gameplay becomes much more fun when the image pleases with the drawing of the smallest details.
  4. Multiple monitors on windows 7 or windows XP are simply necessary for professional programmers who simply take a lot of time to work on a single monitor. On one screen, you can open the code and its result, on the second, documentation and disassembled sections. This saves a lot of time and increases productivity.
  5. The use of two monitors is convenient in production areas, in training, in the service sector. For example, in a bank, an employee's work often involves turning their screen. It is much easier to install a monitor with a "mirror" image specifically for the client. Convenient similar system and in the photo studio.

In fact, connecting two (or even more) monitors to one PC is not so difficult, and it is quite possible to do it yourself. The activation process consists of two stages: hardware and software. At the hardware stage, the PC is connected to the connectors (it is possible to use adapters). On the software - the computer “detects” the monitor. If the screen is not detected automatically, you will need to do it yourself (this will be discussed below).

If the video card has two DVI or VGA outputs, then the connection can be made in just a few minutes. Modern PCs are often equipped with an HDMI connector - it is also suitable for connection, the main thing is that such an output should also be on monitors.

If you only have one video output (DVI, VGA, or HDMI), you cannot connect. How to connect two monitors to one computer in such a situation? You can solve the problem only by purchasing a suitable video card, which has several connectors for connecting screens (this is not necessarily a monitor, a TV screen, and even a tablet display can be used).

Another way out is to buy two video cards. But this is not the best method, as their work will put additional load on the system, and the computer may experience problems.

Connect monitors to PC

This process is not too different for different windows versions. XP, 7 or Vista - the procedure will be approximately the same.

Step one

  • Find the corresponding connectors on the monitors and on the video card of the device;
  • Turn off your computer;
  • Connect the connectors with cables;
  • Press the power button on the PC.

step two

Usually the second monitor should be detected automatically. But sometimes this doesn't happen. Then you can make the screen visible yourself. For this:

  • Press the start key on the desktop;
  • Go to "Control Panel";
  • Select the "Screen" menu;
  • Next "Screen Resolution";
  • Activate the search for the second monitor by pressing the "Find" button.

The procedure for windows 7 and windows XP is similar.

Step Three

Having connected on one monitor, you will see that the second one now shows exactly what is displayed on the main monitor (that is, they work in “mirror” mode). If desired, it is possible to divide the workspace when the monitors will display different information.

Now you need to decide which monitor mode on windows 7 or windows XP you need:

  • Go to the "Control Panel";
  • Select the "Screen Settings" tab;
  • Open the "Settings" menu;
  • Go to the “Extend” item (desktop extension function on the monitor) or to the “Mirror” item (mirror image);
  • Next, you can select the first or second monitor and adjust the resolution, brightness, and color balance.

Additionally, you can go to the Advanced tab, where there are two options for the desktop position - landscape or portrait. It can be configured separately on each of the monitors, on any windows version(Vista, 7, XP).

Solving connection problems

If the connected monitor displays the message "No Signal", you most likely have one of two problems:

  1. Bad contact. To correct the situation, you can disconnect the wire and reconnect. It is not recommended to move the plug strongly, this can damage the connectors on the wire and the holes on the video card;
  2. windows 7, XP (or other) "sees" the new device, but the image is not displayed on the screen. What can be done in this case? The procedure depends on your OS:
  • To configure the display on Windows 7, activate the "Start" menu, then "Control Panel" - "Hardware and Sound" - "Display" - "Connect to an external display";
  • The procedure for Windows 8 is the same, only on last tab there will be an item "Second screen", and you need to select it;
  • In Windows XP, go to the "Options" window in the "Properties" menu. The “parameters” of the window (desktop) are activated by right-clicking on an empty space.

If the device has a discrete video card (nVidia, ATI, others), then the second monitor is adjusted using the built-in utilities.

You can connect a second monitor to almost any PC. The advantages of such an approach are obvious. Do not neglect this feature. If you have the opportunity to purchase an additional monitor and the specifics of the work is related to the full use of the PC, the second monitor will help save time and simplify the operation of the device.

One of my readers had a question about how to connect a second monitor in “clone” mode. To be honest, I did not think that such a question could arise. But, after going through the forums, I realized that this kind of question is not uncommon.

Someone can’t connect a monitor, someone modern TV, someone does not go a new game in multiscreen mode (displaying an image on several screens), etc. So I had a desire to write more or less detailed description options solving the problem with connecting a second monitor.

Below I will present 4 options for solving the problem, one of them should suit you.

connecting a second monitor in windows 7

For those of you who have installed operating system windows7, most likely the luckiest. The developers of this OS have studied the most important problematic issues of users and provided quite effective solutions.

So, if you have windows7 installed, do the following:

1. Connect a second monitor to the output of the video card.

2. Press the key combination “WIN + P” on the keyboard, this picture will appear

3. Select the desired option and enjoy the resulting picture.

connecting a second monitor to a laptop

If you have mobile laptop, then, as a rule, software developers for it have already taken care of the issue of connecting an external device for video output. It is not always convenient to work behind a small monitor, and you don’t want to strain your eyes.

To connect to a laptop or netbook external monitor or TV, you need to refer to the pre-installed system tools. Most often, a utility from Intel is installed. Look in the lower right corner on the taskbar next to the clock there should be a blue (if not an Intel utility, then a different color) icon.

Right-clicking on it will open the control menu graphics adapter.

Or the second option to call this panel is just to click in a free space on the desktop.

Next, select the “Output to” item –> and in the window that opens, select the option we need. To transmit the same picture as on the main monitor, you must select the “Display Clone” mode (underlined in red).

proprietary utilities from nvidia and radeon

I use this method, and it is suitable for all windows operating systems. What needs to be done? Yes, just open the “Video Card Control Panel”, the icon of which is usually located near the clock.

If you are a happy owner of a GeForce video card from NVidia, then the icon is green (as in the figure), and if you have an Ati Radeon card, then it is red, which still has the inscription “Ati”.

Double-click on this icon –> go to the “Video Card Control Panel” –> find “Display Manager” in the menu on the left –> then go to the item “Installing multiple displays” and adjust the resolution for each monitor by selecting the image display option.

working with CATALYST Control Center

This method is also universal, but unlike the previous one, it has great potential in the field of fine tuning and adjusting the image for a specific situation and a specific application.

The name of this generic connection manager external devices information output - “CATALYST Control Center”.

You can download the latest version from the developer's official website by selecting the appropriate platform.

Installing the program should not cause you problems. After launching the program, go to the left menu item “Display Manager”.

AT this section you are prompted to assign a primary and secondary display, select the resolution and color depth of the desktop for each, and rotate the image if your monitor supports this mode.

Setting up the desktop of each monitor is carried out using the context menu called by right-clicking on the image of the corresponding display:

You can choose from three desktop configurations:

  • By default, the found display is connected in extended desktop mode. All programs will open on the main desktop, but you can drag them to the second one with the mouse.
  • Cloning simply creates a copy of the desktop on the second display. This is convenient, for example, for organizing training or various presentations. All you have to do is connect a projector or plasma panel more.
  • The stretched desktop is useful when using two monitors installed in close proximity to each other. Your desktop is fully stretched across both displays, creating a kind of panorama.

Perhaps some of you will say that the second monitor is overkill. But, I assure you that for those who use a computer not only for Internet surfing, but also for work, it creates great convenience and comfort, as well as increases productivity (improves ergonomics).

Also recently, connecting multiple monitors has become popular among gamers. For example, I often connect a TV to a computer in order to watch online movies from the Internet on the big screen with the whole family.

By the way, about monitors, here is a picture to cheer up, called “Milk formula gives 10 health and 10 mana” (do not forget to comment).

How to connect a second, third ... tenth monitor to one computer

The multi-monitor configuration of a PC today will not surprise anyone. And soon, we must expect, the presence of a single display on the table will become the exception, not the rule. So say people who have had the opportunity to compare the convenience of working at a computer with one and several monitors. And the second option, according to their words, is much more convenient than the first.

Statisticians are of the same opinion. According to their research, if you connect 2 monitors instead of one, the productivity of personnel involved in processing a large amount of information increases by 15-60%. What can we say about gamers for whom multi-monitor systems are the only way to go headlong into the virtual world?

How many monitors can be connected to one computer. Connection conditions

It is unlikely that anyone is able to name the exact number of possible monitor connections to one PC, but 50 or more can definitely be. It all depends on the budget that you are willing to allocate for it. To create video walls from dozens of modules, as, for example, in the photo below, special controllers are used. Their task is not just to display the image on many screens, but also to provide each picture with a decent quality.

However, video wall controllers are an extremely expensive solution that not every enterprise can afford. A more affordable option is a video server with several multi-channel video cards. But even it can cost the owner several hundred thousand rubles.

The average user, like most of us, does not need such excesses. Homemade gaming systems consist, as a rule, of no more than six monitors, and they can be connected not just to one computer, but to one video card. But in order to achieve the highest possible image quality, it is better to distribute monitors so that there are no more than two or three monitors per video camera.

Connecting two monitors is supported by almost any modern video card, even built into the processor (chipset). Three or more - All AMD models from Series 5 and NVIDIA GTX 600 and up.

In addition to multi-channel support, the following is important for creating multi-monitor configurations:

  • The presence on video cards of outputs that match the inputs of monitors (the use of adapters is allowed in extreme cases when there is no other way to connect). Moreover, AMD requires a mandatory DisplayPort interface on at least one of the displays (with the exception of individual branded video cards with a built-in DisplayPort-DVI adapter). NVIDIA does not set such conditions.
  • Support by video drivers for resolutions of all monitors.
  • Sufficient amount of video memory. 2048 Mb - a conditional minimum for a two- or three-monitor configuration in a non-gaming system. For four or more monitors, especially if you plan to use the computer for games, the memory should be at least 2 times more.
  • high throughput data buses (from 128 bits) and good speed memory (the more the better). The narrower the tire, the higher the speed should be.

To connect monitors to different video cards, the latter do not have to be combined into SLI or Crossfire. In some cases, in addition to a discrete card (inserted into the slot), you can use the integrated video if the BIOS supports it. motherboard(there is an option "Always Enable" for the output of the built-in video card). But in such configurations, each pair of displays served by one video chip operates independently of the other. This means that creating a common visual space on all screens will not work.

If your computer is equipped with a single video card, you can connect monitors to several of its ports, or to one. To connect 2 or more screens to one video card with 1 input, you will need a signal divider - a splitter. For example, as in the photo below. This modification can distribute a signal to 4 monitors, but the picture quality, as a rule, decreases (it depends not so much on the splitter as on the video capabilities). If the stream is barely enough for a single screen, dividing it into “streams” will reduce both resolution and clarity and refresh rate. And the more connections, the lower the quality.

When connecting a splitter to displays with different resolutions, the picture quality on them will be different: on some it is better, on others it is worse. And you won’t be able to correct it individually, except perhaps through the settings of the monitors themselves.

AMD cards with Eyefinity technology (powered by ATI's Radeon R800 series GPUs) allow you to attach up to 6 displays to them and combine them into a single visual space. But here everything is tied to the DisplayPort interface, which, unfortunately, not all devices are equipped with.

The following are valid combinations of connection interfaces when building multi-monitor systems using AMD Eyefinity technology:

  • To combine 3 monitors into one system, one of them must be connected via DisplayPort or miniDisplayPort (miniDP), the second via DVI, and the third via VGA, HDMI or the same DVI.
  • If there are 4 monitors, two devices must be connected to DisplayPort, the third to DVI, and the fourth to VGA or HDMI.
  • In a five-monitor system, all 5 or 3 monitors are connected to DisplayPort (miniDisplayPort), one or two to DVI and one, if left, to HDMI.
  • A six-monitor configuration provides a connection through miniDisplayPort only.

NVIDIA Surround/3D Vision multi-monitor technology allows you to create a shared gaming space from up to three monitors. However, this requires either a dual-processor video card, or a combination of two or three cards in SLI. You can connect several more displays to the remaining video outputs, they will work independently of the others.

If you do not have the task of building a video wall to display one image on several screens, it is not necessary to adhere to the above rules. Monitors can be connected in any configuration through any interfaces, counting 2 devices per 1 video processor. In this case, each of them will display its own desktop, and you can switch between them, drag windows from one table to another, etc.

How to connect and configure additional monitors in windows

Physical connection of devices

The process of physically connecting a second, third, etc. monitor to the ports of the video card is not difficult. Just plug the connectors of the connecting cables into the jacks of both devices, remembering to unplug them first.

When creating a dual-monitor configuration, use the same interfaces whenever possible, such as DisplayPort only or HDMI only, so that the image quality on the two screens does not differ much. If there are no identical ports on your video card, connect through different ones, for example, DVI and HDMI or HDMI and VGA. Using adapters from one interface to another is permissible only in extreme cases, since signal conversion is always accompanied by its losses, sometimes significant. The same goes for splitters. If it is possible to do without them, try to do without.

After connecting, turn on the power system block and monitors. Recognition of the latter, as a rule, occurs automatically. You just have to customize them to suit your needs.

Connecting a second monitor to laptops is done in the same way as to a desktop PC. The only difference is that the video card that will serve the additional screen is determined by the system, not the user.

Multi display adapters

If the picture quality on the main and additional displays varies greatly, and also if you need to connect not one, but 2 additional monitors to your laptop, a specialized device will help out - a multi-display adapter. This is a small box with a processor inside, resembling a multiport splitter, and a few cables included. With one cable, the box is connected to the output of the video card, the rest are connected to the monitor inputs. It receives power from a USB port or an external adapter.

An example of such a device is Matrox DualHead2Go Digital SE.

Setting up additional screens in windows 10 and 8.1 and 7

After the first turn on, the image on the additional monitor, as a rule, duplicates the main one. Sometimes the desktop is stretched to 2 screens at once. For selection desired mode press combination windows keys+P (Latin) - this will open the projection panel.

In windows 10 and 8.1 it looks like this:

In windows 7 - so:

The option "Duplicate" (Repeated) reproduces the same picture on all displays. "Expand" - makes the second screen a continuation of the first.

If the system was not able to automatically recognize the second display, open the "Display Settings" through the context menu of the desktop.

Click the "Detect" button (In windows 7 - "Find").

If the device is physically intact and properly connected, the system will most likely recognize it immediately. If not, open the "Multiple Displays" list and select "Try to connect anyway..." to a monitor that is not detected.

If this does not help, you should check the contacts and, if possible, connect the device with another known-good cable to another video output or another video card.

The "Define" button in the same section allows you to select which of the two displays will be the main (first), and which - additional (second, third, etc.).

To change the settings of one of the displays of a multi-monitor system - the size of the displayed elements, the brightness level, the orientation, the resolution, the color rendering, etc., click on the rectangle with its ordinal number in the gray field under the heading "Customize your screen".

Changes will take effect after saving. You don't need to restart your computer for this.

Additional configuration settings for multiple displays are found in the NVIDIA and AMD Catalyst Control Panel menus.

Setting up additional screens in windows XP

To access the display settings in windows XP, also open the context menu of the desktop and click "Properties". Next, go to the "Settings" tab.

If the second monitor is correctly recognized, 2 display icons with sequential numbers will appear in the gray box. The "Find" option, as in modern versions of windows, is not here.

By default, the same desktop image is displayed on both screens. If you want to stretch it, click on the second display icon and check the "Extend desktop to this monitor" box.

Setting up each screen individually is done in the same way as in windows 10: click on the monitor icon in the gray field and set the desired parameters. The "Screen resolution" and "Color quality" options are there, and the rest - scale, adapter properties, etc. - is hidden behind the "Advanced" button.

Most of the settings take effect immediately, but some - only after restarting the computer.

Connecting a second monitor (TV). Switching between monitors in windows. +90

Sometimes the question arises of connecting an external monitor, TV or projector to the computer. The reasons for this action may be different: there is not enough working space for one monitor, there was a desire to watch a video or play on a new large-screen TV, or you need to make a presentation by connecting a projector to your computer.

Connecting a second monitor. Connector types

To implement one of the above tasks, or something similar, firstly, you need to acquire the necessary equipment. To connect a second monitor or TV to a computer, you need a video card with at least two outputs (HDMI, DVI, VGA, etc.). Most modern video cards are equipped with two or three output connectors, so this should not be a problem.

Attention! All connections to the video card should be made with the computer turned off.

If everything is connected correctly, then immediately after turning on the computer, the image will be displayed on both monitors, but after a few seconds, the additional screen will turn off. This is because the video driver controls the display of images, and two monitors will work until it is loaded.

Setting up windows to work with two monitors

Now it remains to configure the display on the main and additional monitors. The fact is that the computer defines one monitor as the main one, the other as an additional one. You can configure dual monitor modes in windows 7 in the Display Settings window. To do this, follow the link Screen resolution from the context menu of the desktop

In this window, you can assign a primary monitor and a secondary monitor, set the screen resolution, select the display orientation, and select the dual monitor display mode.

In the settings it is possible to change their roles and places. There are four options for displaying an image when connecting a second monitor (projector, TV):

  1. Display desktop only on 1 In this case, the image will be displayed only on the main monitor.
  2. Show desktop only on 2 The option is similar to the previous one, only the image is displayed on an additional monitor.
  3. Duplicate these screens When this mode is active, the image is duplicated on both monitors.
  4. Expand these screens When activated this mode the taskbar will be displayed only on the main monitor, and the second monitor extends the boundaries of the first. By default, open programs will be displayed on the main monitor. They can be easily dragged to an additional screen by grabbing the title bar with the mouse.

Depending on the location of the main and additional monitors, the space may expand in different directions. The relative position of the two monitors can be adjusted by simply dragging the monitor icons in the display settings window

The Detect button allows you to determine which monitor you are currently behind. When you click on it, a large number appears on each of the monitors, indicating the number of the monitor in the windows settings.

It is very convenient to switch the image display modes on monitors using the Win + P hotkey combination. When you press win + P, all 4 options for displaying an image on monitors are available. Switching between monitors is carried out as follows: simultaneously press Win + P and, without releasing Win, press P until the desired mode is selected

Also, the combination of hot keys Win + P may be needed in the following case. You used two monitors, and then removed one of them from the system, and at the same time the main one. The next time you turn on a computer with one monitor, the screen may be black. This is where the combination Win + P is needed to switch the mode.

If you have an ATI video card and when outputting to a TV or a projector, the image does not occupy the entire screen, and you see black bars around the edges, then you need to turn off the scaling mode in the Catalyst Control Center video card driver settings by setting the slider to 0. The scaling mode is used in if the permission additional monitor or the TV is larger than the main one.

How to use multiple monitors in windows 7

When I work a lot with the computer, a way to increase the efficiency and organize myself better tasks is to use multiple monitors for the same computer. In windows 7, adding a second (and third - if you have two VGA ports to your computer/laptop) monitor can be configured in just two ways:

  • shortcut Keyboard: Use the keyboard shortcut windows + R (where windows key It's a windows key sign on it)
  • Control Panel > Appearance and Personalization > Display > Change Display Settings (Or just right click on Desktop > Screen Resolution)

Using the windows + P key combination highlights one desktop Quick menu of options (which can be accessed from Control Panel > Display > Connect to Projector) Namely: Computer only (Using the primary monitor only) Duplicate (Shows the same desktop on both monitors) Extend (Extended desktop to two monitors connected) and Projector only (Use only the second monitor), from which you can choose the most convenient for you (as a rule, when you connect a second monitor to a laptop, the windows option is automatically selected, duplicates ).

The second way is to set up multiple monitor screen resolution. The 1 and 2 numbers displayed on the monitors will help you to distinguish between the primary monitor and the secondary when you want to change the settings for them (well, you can click on the Identify button to ensure that they are displayed correctly).

To set the display mode on multiple monitors use the drop down next Multiple screens It contains all the quick menu options displayed context windows+P.

How to connect two monitors to a computer or laptop: setting up in windows

In order to increase productivity when working at a computer, many users decide to connect a dual monitor to a system unit or laptop. Working on two screens, you can expand the desktop space or, if necessary, duplicate the image from one of them to another. You can connect two monitors to almost any computer or laptop, but this procedure has a number of nuances, both on windows 7 and on windows 10, which we will pay attention to in this article.

What you need to connect two monitors to your computer

An external monitor is connected to the system unit or laptop through the output on the video card. To connect two screens, it is necessary that the video card can send a signal through at least two outputs. Almost all video cards released since 2005 have two or more connectors for connecting an external monitor. On laptops, as a rule, there is only one such connector, but in this case, the laptop display itself can serve as a second monitor.

Most often, DVI, VGA and HDMI connectors are used to connect the monitor ( various versions). On modern laptop models, a USB Type C or Thunderbolt connector can also be used to transfer information to an external monitor. Due to the obsolescence of VGA technology, the user may encounter a situation where it is impossible to connect a monitor due to the lack of a corresponding connector on the video card. In such a situation, adapters, for example, HDMI-VGA, which are easy to purchase, will help.

Please note: Your monitor may have multiple ports for connecting to your computer. Before purchasing an adapter, we recommend that you carefully examine all the connectors on the back of the display.

How to set up dual monitors

Most often, when connecting the system unit in the operating room windows system to the monitor, all necessary settings are performed automatically. Accordingly, immediately after the system boots, both screens will work, and the user will only have to configure the monitors' mode of operation. The following three options for computer operation are possible under windows control with monitor:


The operation of two monitors is handled differently on modern windows 10 or more early versions operating system. Consider how to set up two monitors in different versions of windows:


Please note that if the image on the monitor is blurry, you must also select the correct resolution in the screen settings.

It is worth noting that some video card manufacturers release their own software that allows you to set up two monitors on your computer. If you have such software, you can use it to customize screens, most often it is more functional than standard settings in windows.

Consider how to connect a second monitor, and what is needed for this. The following instructions are for Windows 7 and Windows 10. Before you start connecting, determine what you will use the second monitor for and select desired type connections.

The second screen is useful in such cases:

  • For watching a movie and surfing the Internet at the same time. Also, you can turn on the game, and watch the video on the second monitor;
  • View multiple browser windows at the same time;
  • Video editing. This procedure takes more than one hour, so using a second monitor will allow you to control the installation and continue to use the PC.

There are three possible connection modes - switching the picture to the second screen, duplicating the image on both monitors, or continuing the desktop on the second screen.

In the first case, as soon as the new display is detected, the first screen of the computer will turn off and you will only be working with the second monitor. Image duplication allows you to see the same process on all connected monitors. An extension is a type of connection in which the new screen becomes a visual extension of the first one, which allows you to run several programs at once. An example of an extension is shown in the figure:

Requirements and connection types

To work with multiple screens, your computer's video card must support this feature. On older computers, it can be difficult to connect to an integrated graphics card, but more than 90% of modern PCs will “see” a second display without any problems.

There are several connection types:


Wired connection of a second monitor

Before you can connect a second monitor to , you must make its physical connection to the system. Decide on your monitor type (analog or digital), then look for a VGA or HDMI output on the back of the display. A similar connector should be in your computer.

Take a wire for connection and connect two VGA connectors or two HDMI connectors (one on a computer or laptop, the second on the monitor itself). Make sure the wire is well connected to both devices. The slightest inaccuracy can provoke an arbitrary shutdown of the second monitor.

At the last stage of the connection, you need to turn on the power additional screen i.e. plug it into a power outlet. The cable connecting the screen and the PC and the power cable are included with the monitor. If necessary, HDMI-HDMI or VGA-VGA adapters can be purchased at any hardware store.

Instructions for Windows 7

After the physical connection, you can start setting up two displays. Let's see how to do it in . Often in this version of the OS, nothing can happen immediately after connecting. On the second screen, the image does not appear until you move the mouse or do some other action on the first monitor.

After the appearance of a duplicate picture of the first monitor on the second, you need to proceed with the settings. Built-in OS options allow you to select the type of display of the desktop and other windows. The user can continue to use both monitors in image mirroring mode or adjust their extension.

In the first case, it will be convenient to watch movies. For example, you want to connect your TV as a second monitor to watch videos and do not need to work with other computer functions in parallel. Choose duplicate pictures.

If you want to work on your computer while watching movies and opening other programs, choose an extension so that the second screen desktop becomes an extension of the first one.

Follow the instructions to open the settings window:

  • Right-click on an empty space on the desktop;
  • In the list of actions, select the "Screen resolution" item;

  • In the new window, click on "Find" if the second monitor did not turn on automatically. Also, in these settings, you can click on the number of the screen you need and adjust its resolution, orientation and type of desktop display;
  • To expand two monitors, open the "Multiple Displays" option and select "Extend these displays" from the list.

How to connect a second monitor to Windows 10

To connect and configure a second monitor in Windows 10, follow the instructions:

  • Open the system settings window by pressing the Win + I key combination;
  • Click on the "System" tile;

  • In the new window, select the "Display" tab and in the right part of the window click on "Screen Resolution";
  • Further, as in Windows 7, select the monitor number and configure the type of image display, its resolution, and other available options. Note that in Windows 10 it is possible to connect to a monitor that supports wireless connection.

Errors when connecting a monitor and solutions

When connecting two, three or more displays to one computer, problems often arise. Let's consider what to do if the computer does not see the second monitor or there are problems with the image.

Image distortion

If you encounter severe image distortion on the second monitor, most likely the gadget is connected using an analog VGA cable. Loss of quality in such cases is the norm, because for the transmission of an analog signal, a double conversion of data bytes is performed. Eventually. Information is "lost" on the way to the second screen and the picture is not of the best quality.

Sometimes image settings can fly off. We recommend that you go into the display configuration menu and check which resolution is selected. It is possible that the second screen automatically chose low quality or inappropriate scaling:

If your PC video card has an HDMI input as well as a VGA one, it is enough to use another monitor with digital connection support to solve the problem.

Randomly turn off the second monitor

If after you've managed to connect a second monitor to your laptop or PC, the second screen suddenly turns off, the problem is with the cable. It may be damaged, or you may not have connected it properly in the computer's connector panel. Also, check the power of the monitor, the corresponding connector and socket may also be broken.

The second reason for a sudden shutdown is a malfunction of the video card drivers. The software needs to be updated. To do this, go to the Device Manager window.

Follow the instructions to open the Manager in Windows 7:
  • Open the "Start" menu on the left side of this window, right-click on the "My Computer" field;
  • In the drop-down list, select the "Management" item;

  • On the left side of the window that opens, select "Device Manager". The following window will appear:

To open the Manager in Windows 10, follow these steps:
  • Right-click on the Start menu icon;
  • As a result, a list will appear quick access, in which you need to select the following field:

If the laptop does not see the second monitor, after launching the Device Manager, you can update the drivers automatically. To do this, just right-click on the "Display adapters" item, and then select "Update configuration" from the list. A similar action must be performed for the "Monitors" device group:

The computer will send a request to the Microsoft server and begin searching for new driver versions. An Internet connection is required to complete the installation. After updating the software, be sure to restart the computer and reconnect the secondary display.

Nothing happens after connecting.

The reason why the second monitor is not visible at all is the incorrect definition of the connection type. You may have used a digital HDMI connector while your graphics card only supports analog VGA.

It should also be noted that the video card can only support one connected monitor. In this case, the only way to solve the problem is to install a new video card.

Now you know how you can connect a second monitor to a computer or laptop. In case of problems, check the scaling settings, reinstall the integrated video card driver software, or try a new connection cable. If you have any questions while setting up the second screen, leave them below in the comments.


There are only three options for connecting 2 monitors to one computer. Almost any user can use them, regardless of the experience of using computer technology.

Although the most effective options will have to make certain costs. And, in any case, to configure the system and data display mode.

The need for two monitors

There are many options for using two displays at the same time on one computer.

First of all, such a system with multiple monitors will allow you to keep many more windows fully open.

For a designer, constructor and photo artist, an enlarged working area means greater detail of objects.

Users who use graphs and diagrams also increase work efficiency - with two monitors there is no need to constantly switch between several documents, which are conveniently placed on one, doubled area.

Another fairly common possibility of using two screens is gaming applications. They provide best review on both sides.

And for laptop owners, an additional wide screen (which can even be used as a plasma TV) allows you to get much more pleasure from the game.

Two screens will also come in handy for programmers, giving them the opportunity to see how the result of their work will look in several browsers.

In production, during the educational process and in the office - each such workplace or study place may require displaying information from one computer on several monitors at once - this will save both space (you will not have to sit together at one display) and money (no need to purchase another computer).

Connection steps

The first stage of connecting (physical) multiple screens is quite simple.

This will require that the computer has a sufficient number of inputs of the appropriate type, the same number of cables and, if necessary, adapters.

After that, the system itself can determine the presence of two information output devices and adjust the image, or you will need to manually configure using standard Windows Tools(or other OS).

There are only three ways to physically connect 2 monitors:

  1. With the help of a video card that has several outputs (Fig. 3). If the computer was purchased to work with graphics, and the video card is modern and powerful enough, it may already have several connectors installed - for example, 2 HDMI or 1 VGA and 1 HDM. If there is only one input, you may need to purchase a new video card;

2. Installing an additional video card in the second slot of the motherboard.

This option is suitable if you have an old GPU on your computer, and there is no possibility of buying an expensive new board with 2 inputs;

3. Using a special splitter (splitter). This method is the most inexpensive and suitable for any computer, however, it can lead to a decrease in the allowable frequencies for monitors.

Image quality will decrease, which will be especially noticeable when running on FullHD video screens. To work with static images, the use of a splitter is quite acceptable.

Advice: when using a laptop, the possibility of connecting a second monitor should already be provided (there is an additional connector in the side part). Changing the video card on many portable computers is not only expensive, but often simply impossible. However, most modern laptops and even netbooks have a monitor input by default.

Compatibility of cords and inputs. Ports

To connect monitors to computers, a cable is required to align their connectors. Two displays will require the same number of cables of the correct type.

Connectors can be as follows:

VGA. A few years ago, this was the standard connector for most monitors and computers.

Now to combine an old PC and a new display, or, conversely, an outdated screen and modern device, an adapter may be required;

DVI. A more modern interface that provides support for analog and digital signal;

HDMI. The connector is suitable for connecting a computer to devices with clear digital signals, such as TVs and plasma panels.

Often found not only on PCs, laptops and TV sets, but even on tablets (in the form of miniHDMI);

DisplayPort (mini DisplayPort). An interface that has a number of advantages over even HDMI.

Not very common, but allows you to connect multiple screens with a higher resolution (up to 4K);

USB. A standard port that has been found on computers for over 15 years. Not very suitable for transmitting high-quality images and is rarely found on monitors.

However, it solves the problem of compatibility, for example, for a laptop or netbook with missing connectors for video of a different type.

Basically, it is simply impossible to connect the cable incorrectly due to a large number plug differences.

The only problem that may arise in this case is the lack of suitable adapters. And all you need is to find and buy the right parts.

For laptops with a monitor connector, the task is even easier.

And if you want to connect your computer to a TV or monitor located at some distance, you should use WiFi extenders.

Monitor setup

After 2 monitors have been connected to the computer, the operating system usually quickly detects and configures both on its own.

And on each screen, you can see the same image, which can be convenient when transmitting the same information to a group of users.

Advice: at different resolutions of monitors, the images on them are automatically adjusted. Therefore, it is desirable to use screens with the same aspect ratio (4:3 or 16:9).

However, in some cases auto tuning does not happen - one monitor starts up normally, the second shows no signal.

Most often this happens due to a bad signal (especially if splitters for 2 monitors are used).

Another reason is the lack of suitable operating system settings.

To fix the problem, do the following:

  • Open the "Display" tab - through the "Start" menu (for W7 and higher) or through the settings tab in the desktop properties window (for W XP);
  • Select Screen Resolution Settings.

If both screens are connected, configured and working properly, you will see two images with numbers.

Here you can also adjust the resolution of each display and even its orientation (for example, turning it on its side and working with an image in portrait format).

When one of the screens is dimmed, press the Find button.

If the monitor was connected correctly, the system will set it up after a while and enable the output of information.

Now you can press the Win and P keys at the same time, after which you can see the settings panel on the screen.

Selecting the item " Duplicate”, you get the same image on each display.

When choosing " Expand» The picture will be enlarged by as many monitors as are connected to the computer.

There can be not only two, but also three or even 9.

Laptops sometimes have a special button for more convenient connection and configuration of an additional display.

With it, you can switch the image from laptop on a large display.

In this case, the laptop may show the same image, part of the image, or even turn off if the connection was made to improve the usability of the device.

Two desktops

Often a situation arises when the monitors should not have a duplicate or extended image, but two completely different pictures.

It is almost impossible to implement such an opportunity using your own computer.

To do this, you will need to purchase a professional (or additional second, which may be ordinary) video card and organize several independent information flows.

A special device will help simplify the task, the task of which is to connect two monitors to one computer and organize two workflows.

Device called M atrox DualHead2Go will allow you to work with 2 displays, even with a low-power GPU and analog output.

In addition to connecting the adapter itself, for its operation you will need to install the drivers that come with it.

If necessary, with the help of Matrox DualHead2Go you can connect two monitors even to a laptop.

Thus, mobile computer will immediately receive 3 displays, 2 of which will show one information, and the third - another.

Tablet use

If desired, you can connect not only a full-fledged monitor or TV, but also a regular tablet as an additional screen.

This will require the installation of one of two applications:

  • ScreenSlider that works with Android;
  • iDisplay for both Android and iOS.

Each program has two parts - for a computer and a tablet. At the same time, both Windows and MacOS can be installed on a PC.

The first part will add a new virtual monitor to the system, the second will start working on the tablet only after the IP of the computer has been entered.

With both applications, you can stretch the image across multiple monitors or duplicate the image. They will also help set the orientation of the screens.

findings

After you have managed to connect and configure both monitors, you can get an image extension, increasing the level of convenience for working or playing.

If at the same time there are still some small problems with displaying data (black bars at the edges or insufficient clarity), it is worth checking the settings of the video card (several video cards) or updating the corresponding drivers.
