Hdmi cable connect to computer. Step-by-step plan for connecting a TV to a computer via HDMI with Windows setup

HDMI output (High-Definition Multimedia Interface) is needed to transmit the highest quality digital signal. It is used for video and audio broadcasting. So, HDMI, how to set it up? First, a little preface. It must be said that almost all personal computers are equipped with video cards with an output such as HDMI, in addition, HDMI is quite common even on those laptop models that use a standard integrated video card. Let's, for starters, we will try to explore the capabilities of your video adapter. In the event that your video card does not have an HDMI output, you can use the DVI or VGA channel using a special adapter, which is also called a DVI-HDMI connector. A feature of such adapters is the ability to transmit sound signal.

How to set up a TV via HDMI? For HDMI settings you will need instructions from the TV to which the connection will be made, where they will be written specifications. Be sure to make sure that the HDMI input is designed to receive audio. To connect to a TV, you only need an HDMI-HDMI cable, one end of which must be inserted into the computer's video card, and the other will need to be inserted into the TV's connector. If you want the monitor and TV to work at the same time, you will need to enable such a function as the synchronous operation of these devices.

Synchronous operation of devices

To do this, you will need to open the "Start" menu and go to the "Control Panel" (you can go there in any way convenient for you). Next, you will need to select "Screen" and go to the "Screen resolution settings" item. In the dialog box that appears, you will need to activate a feature such as "Duplicate Screen". From now on, the computer will transmit the same image to all devices connected to the video card. If you have a need for both displays to start working separately from each other, you will need to activate the "Expand Screen" mode. In this case, you will need to first assign the display as the main device of the computer.

How to set up sound via HDMI? To set up HDMI, you will need to adjust the audio signal transmission. To perform this action, open the "Control Panel" and click on the "Hardware and Sound" item. Then you need to select "Manage audio devices". A dialog box will appear on the screen, in which you will need the "Manage sound devices" tab. Well, here you need "HDMI Output". Click on its icon with the left mouse button, set "Default".

Now you need to click on the "Apply" button and close the dialog box with "sound devices". Next, as a test, you will need to run some video and make sure that the HDMI output and cable are working properly. It is worth noting that if you unplug the hdmi cable, then the standard audio port will turn on automatically. How to setup HDMI cable? As you can see, the HDMI output is quite easy to set up and you don't need any special knowledge to do it. I almost forgot to tell you about which HDMI cable is better and which one should be chosen for further long everyday use.

Types of cables

There are two types of HDMI cables: high definition and HDTV. It is also worth touching on the topic of the length of the wires and take into account in advance that the length can vary from 1 to 10 meters; but do not forget that the longer the cable, the more likely it is that there will be signal loss. As a result, some manufacturers have sprung up to offer so-called "active" HDMI cables with various technologies that can be used to transfer data over very long distances. When you buy a cable, be sure to point yours to the wire as well as its connectors.

The idea of ​​connecting a computer or laptop to a TV can be quite reasonable if, for example, you often watch movies stored on your hard drive, play games, want to use the TV as a second monitor, and in many other cases. By and large, connecting a TV as a second monitor of a computer or laptop (or as the main one) for most modern TV models is not a problem.

For your computer, the connected TV is just a second monitor, respectively, and all settings are made in the monitor settings. On Windows 10, you can run necessary settings in the following way:

In general, the setup can be considered complete at this point, unless you need to make sure that the TV has the correct resolution set (i.e. the physical resolution of the TV screen), the resolution setting is done after selecting a specific screen in the display settings of Windows 10. If you do not see two displays, instructions can help: .

How to adjust the image on the TV from a computer and laptop in Windows 7 and Windows 8 (8.1)

Click right click mouse in an empty area of ​​the desktop and select "Screen Resolution". The following window will open.

If you have both a computer monitor and a connected TV working at the same time, but you don’t know which one corresponds to which digit (1 or 2), you can click the “Detect” button to find out. You will also need to check the physical resolution of your TV, usually on modern models it is Full HD - 1920 by 1080 pixels. The information must be in the instruction manual.

Setting

1. Select by mouse click the thumbnail corresponding to the TV and set in the "Resolution" field the one that corresponds to its real resolution. IN otherwise, the picture may not be clear.
2. If multiple screens (monitor and TV) are used, select the operating mode in the "Multiple displays" field (more details below).

The following operating modes can be selected, some of them may require additional configuration:

Apply settings and enjoy. The best option, in my opinion, is to expand the screens. At first, if you've never worked with multiple monitors, this may seem a bit out of the ordinary, but then you'll likely see the benefits of this use case.

The number of pixels on a TV, whether it's LCD or plasma, is fixed. It depends on which company released it, on the diagonal of the screen, and the generation model range. But, today, LG TV, capable of transmitting a picture with hdmi resolution of 1366x768 using the LCD panel of the screen, has to work in 720x576 pixels mode. This is because it is the standard for a conventional television signal. But an expensive TV model from Samsung and LG easily works in a mode that not every monitor has - 1920x1080 pixels.

It is logical that through a cable that allows you to connect to a high-quality hdmi signal source like a netbook or laptop to your LG TV, you can get a better picture. After all, passing through modern processors, which are equipped with PCs, the video signal is significantly improved. In addition, for PC created special programs, allowing you to use the LCD screens of expensive TV models to the limit of their capabilities. At the same time, a high-quality hdmi cable does not affect the picture quality of LG TV receivers.

Advantages of connecting TV equipment to a computer

Samsung's large LCD panels are great for broadcasting an HD movie through them. The diagonal size of the TV in hdmi mode allows you to see many details that are invisible on the monitor screen. Fans of LG technology, who use Internet capabilities instead of a relay network using a netbook or laptop, will understand me. The LCD screens of these types of PCs have a small diagonal. At the same time, this LG technique is able to give a high-quality digital signal. And although big expansion monitor and can convey all the nuances of the picture, its size makes it impossible to comfortably watch movies.

Previously, for any laptop, the rule “it is only for work” was applicable. Today it is a full-fledged PC with all the advantages of this category of technology. And for this reason, a netbook, as well as a laptop today, has hdmi connectors that allow them to be connected through a special cable to a modern TV, it doesn’t matter if it’s LG, Rainford or Samsung - the main thing is that they also have an hdmi connector.

PC hard drive - like a TV tower for a TV

Connecting a TV to personal computer it is beneficial not only with a high-quality picture on the LCD panel of the satellite. Samsung is a renowned manufacturer of quality hard drives. Any of them through the hdmi connector, using a special cable and appropriate programs on a PC, can be turned into a signal source for the latest generation TV from LG. And instead of watching a 720x576 movie through a large Samsung LCD panel, or using the same LG monitor with a resolution of 1366x768 but with a small diagonal LG LCD screen, you can combine the best of both options.

Even with the help of a netbook, you can watch high-definition Internet TV through any TV model with an HDMI connector and a connecting cable. This is also possible with a laptop and any stationary PC. After connecting modern TV to a personal computer, you can independently manage the information flow coming through communication networks.

We connect your TV to LG computer equipment

To connect your own TV to any PC option, from a laptop to a stationary system unit manufactured by LG and other companies, you must:

1. The presence of hdmi connectors both on a laptop or video card of a PC-station, and on your TV.
2. Cable with two hdmi connectors through which devices are connected.
3. Some TV models only have a DVI connector. Then you can use special hdmi-DVI adapters to connect to a computer. In both cases, the signal to the LG LCD panel is transmitted in the same way. The main difference is that the DVI cable is capable of transmitting an analog signal through itself.
4. The use of special software is recommended. It is designed to provide full functional use of a flat LCD TV instead of a standard monitor.

Using a PC as a TV source using a jack connection high precision hdmi is not only an opportunity to see old movies in “new color”. It is also a way to open all the possibilities of LG screens laid down by the creators.

Setting up an additional monitor for a laptop

After using a special cable to connect the hdmi ports on your PC and TV through it, some people forget to switch to the correct input. And instead of pressing one button on the TV remote, they call service center LG, complaining that the model does not work hdmi. Or they start changing the settings on the computer, pulling the cable. And from such actions after a while it really breaks down.

LG remote controls have special button to convert your TV to accept an hdmi signal from a connected PC and turn it into a larger version of a monitor. Press the button, then select the connector to which the cable is connected. Everything, the picture from the laptop should appear on the screen of your LCD panel in a second. And instead of small, albeit very clear pictures visible on the monitor screen, we can see all the small nuances on the large diagonal of the LG LCD panel. Further control of the video stream is performed using a laptop or other PC version, the connection of which is possible via a high-definition hdmi connector.

Duplicate laptop LCD screen is not always convenient

It is not always convenient to connect a separate LCD screen that duplicates PC information. Therefore, the use of an additional LG LCD panel with a laptop is possible as another desktop. To do this, after connecting your PC using the Windows Mobility Center settings, select the “Extend” option.

The external LCD now uses the cable and hdmi connection as a tool that allows you to add a computer additional screen. At the same time, the PC is easily able to support the broadcast of the movie in hdmi-quality via cable, and the user can simultaneously give the computer parallel tasks on the second video panel. You can also set the following operating modes through the mobility center:

1. "Computer only." Although a cable is used to connect equipment via hdmi connectors, in this mode the picture is only on the PC LCD screen.
2. "Duplicate". Information from the PC screen is duplicated on the LG panel one to one.
3. "Expand". The user himself asks the computer what and which of the LCD screens in this moment broadcasts.
4. "Projector only." Through the connecting cable, the picture is sent only to the connected LCD panel. The PC screen is inactive.

For extended use of LG LCD flat screens, the Projector Only mode is recommended. For work, it is optimal to work together with a PC and an additional screen via an hdmi connection and the “Expand” option. But in fact, each person decides for himself the question of his own comfort.

Note.

Many owners of both devices try to connect a computer to a TV via HDMI. Some get it right away, others have problems. Let's say right away that at first glance, it would seem that it is not a difficult task, but it can turn into many problems.

Connection problems

What are the common problems:

1. There is a picture on both devices, but the sound on the TV responds;
2. There is an image on the monitor, but it is not on the TV or there is an inscription, “Cable is not connected”;
3. With a high resolution of the TV screen, for example, Full HD 1920x1080, the computer monitor distorts the image.

Terms and Conditions

Conditions under which it will be possible to connect a computer to a TV:

1. The presence of an HDMI cable, preferably version 1.4 and higher if you need support for 3D mode;
2. The presence of an HDMI output on a computer video card or laptop;
3. If possible, support two devices of the same screen resolution;
4. Installed OS Windows 7, 8, 10.

HDMI cable must be selected the correct length, the choice here is large, you can find cables up to 20 meters long.

Often the LCD TV is attached to the wall. For many, when connecting an HDMI cable to it, this causes difficulties, although everything is simple here, everything has already been invented before us.

Use, invented just for such a case.

The 90 bend can be in different directions, so before buying such a corner, consider where the cable will go.

You may also encounter the problem of the lack of HDMI output from the video card. Look, it can be built in somewhere else, for example, integrated into the system board.

If it is not there either, then it will not work to connect the computer to the TV, unless there is a second DVI output on the video card.

For this case, you can use a DVI-HDMI adapter as a solution to the problem.

If you want to connect other devices to the TV, for example, a camera, then it must have a mini-HDMI output. This also applies to tablets, netbooks, etc.

Accordingly, the cable must be appropriate.

If, for example, the TV has only one HDMI input, and there are many sources, for example, a computer, laptop, camera, tablet, etc., then you can additionally get an HDMI switch, the so-called “switcher”.

Using the special remote control included in the kit, you can quickly switch between data sources.

You can save money on switchers by buying a cheap Chinese version from 5 to 10 dollars. You can order directly from China, though you have to wait a couple of weeks.

They work no worse than those sold in our stores. And expensive models will be justified only if you often watch videos in Full HD quality.

What does the user get

By connecting the TV to a computer and other devices, it becomes possible to:

• Watch videos of any format, from AVI, MP4, MOV to Full HD and Blu-ray, from the TV screen;
• View slide show;
• Play computer games;
• Chat in in social networks and on skype
• Work with documents and programs;
• View large format photographs;
• Conduct online conferences and much more.

It is convenient, practical, modern.

When we figured out all these points, we proceed to connect the computer to the TV.

Connection process

Let's take TV as an example. An expensive model, but it doesn’t matter, in most cases the algorithm of actions is the same for both expensive models and cheap ones.

Wimdows 7 operating system, read how to install it.

We connect our HDMI cable to the appropriate sockets on a computer or laptop. At the same time, the monitor is connected to the computer via the DVI output.

ATTENTION- all devices must be de-energized, otherwise the HDMI ports may fail and then you will not connect anything anywhere.

The TV has four HDMI inputs, which is good news. One of them is visible in the photo.

We connect our cable to it. We carefully check that the connectors are tightly seated in the sockets.

We turn on both devices and watch the monitor and TV.

As a rule, such information appears on the TV screen:

1. Cable not connected;
2. Check the source setting and cable connection.

This situation needs to be corrected.

We take the remote control from the TV in our hands and press the button "Source" (Source), it is located at the top right.

In the menu that appears, select "External", and then press HDMI and confirm by pressing the button on the remote control located in the middle.

If everything is connected and configured correctly, then on the TV screen you should see the splash screen of the computer desktop.

If not, then the screen extension settings are not configured.

Here we are using the method − duplicating screen.

To change the settings anywhere on the computer desktop, right-click, and a window with a menu will appear.

Press " Screen resolution" and configure the settings as follows:

• Screen - ½ multiple monitors;
• Resolution - 1920 x 1080 (TV screen resolution, yours may be different);
• Orientation - landscape;
• Multiple Screens - Duplicate these screens.

For TV screens that support a resolution of 1920 x 1080, you can set the resolution to 1280 × 720, while the stash of folders and files on the TV will be displayed in large sizes.

Click "OK".

Such actions should correct the situation.

Screen resolution problem

The problem may arise in the mismatch between the resolution of the TV screen and the screen of the monitor or laptop.

For example, there is an LG 19M35A-B monitor that supports HD 1366 x 768 resolution, and we have a TV that supports 1920 x 1080 screen resolution in Full HD video format.

In this situation, it will not be possible to achieve an ideal picture simultaneously on both screens. Here you need to choose what is more important now and set such a resolution in the settings (see above).

Or get a monitor, for example, LG 22MP55D-P, which already supports Full HD 1920×1080 resolution and then you will have a perfect image on both devices.

Desktop extension method

This method is not suitable for everyone. It is necessary that in the settings of the video card of your computer there was an opportunity to configure the resolution of several displays.

Most NVidia video cards have such capabilities.

Again, right-click anywhere on the screen and go to "Screen Resolution" (see above).

• We expose the main screen, for example, the BeenQ monitor;
• Resolution 1280 x 1024;
• Orientation - landscape;
• Multiple screens - expand these screens.

No sound

Reason 1

Situations when there is no sound after connecting a computer to a TV are common.

It must be remembered that both video and audio signals are transmitted through the HDMI cable, and if the TV supports 3D, you need a cable version 1.4 and higher.

But, as a rule, this is not a hardware problem, but a software one. All settings are in Windows 7.

At the top, click on the "Sound" menu item.

By going to the next section, you may not see the device we need there.

To make it appear, right-click anywhere in the window and click "" in the additional window that appears.

We have Samsung - 1. We activate it by right-clicking and the "Enable" menu item. Don't forget to click OK.

Now the sound on the TV should appear.

Reason 2

The next reason for the lack of sound is the lack of support for high definition audio output.

To see if it's supported given function computer at the moment, go to "Device Manager".

To do this, right-click on the icon "Computer" - "Properties" - "Device Manager". Or press the Win+Pause hotkeys.

Pay attention to the item "", there should be as shown below.

If there is no such device, then reinstall the drivers on the video card or update them.

Reason 3

If the TV has several HDMI inputs, then, as a rule, the first of them is guaranteed to receive digital audio by default, while the other inputs need to be configured (depending on which TV model).

To do this, you need to delve into the settings of the TV and set the desired parameters.

Some moments

If you want the boot process to be displayed on the TV screen and not on the monitor screen when the computer boots, then disconnecting the latter from the network will not be enough, it must be disconnected from the DVI output.

Outcome

Summing up, we can say that connecting a computer to a TV is not difficult, it is enough to get an HDMI cable of the right length and have the necessary inputs and outputs on both devices.

At the same time, hardware problems, as a rule, are quite rare, basically you need to know how to correctly set certain settings in Windows 7 in the TV settings interface.

Video on connecting a laptop to a TV.

Under ideal conditions, all work will take you up to 10 minutes.

There are several situations when you need to connect your TV to your computer via HDMI or USB cable. Fortunately, modern TVs fully support this feature. But first you need to clarify in what specific capacity you want to use this bundle. Well, for example, you can simply use the TV instead of the monitor. This method is the most common, and when a user enters a query on the topic of our article in a search engine, he usually needs this information.

How to connect a TV to a computer instead of a monitor?

Quite often there are situations when it is advisable to connect a TV to a computer in order to have a larger monitor instead of a small screen. For example, if you're playing a game, it's much nicer to see everything on a large display. Or if you want to watch a movie from the Internet directly on your TV, but your zombie maker does not support an Internet connection.

There is such a situation when the computer has only a DVI digital output, and the TV has HDMI, how to connect them in this case, because DVI is not designed to transmit sound? There is a way out, but it does not always work - you can try using a dvi-hdmi adapter connected to your computer. And already connect the hdmi cable to it and stretch it to the zombie. At the same time, to transmit sound, you need on the motherboard from the built-in connector sound card S / PDIF (if it is available, of course) transfer the audio signal through the internal cable to a similar video card connector so that it is also fed into the DVI output. Again, this option may not work on all models. motherboards and video cards, so it's better to choose simpler methods.

How to mirror screen from PC to TV via wifi on Windows 7 or 10?

Displaying a computer screen image on a TV can be realized not only by different types cables, but also via WiFi. There are several ways to do this.

• On computers with Intel processors and Windows 10 already has a built-in feature called . With its help, it is easy to duplicate a computer screen on a TV wirelessly without third-party software.
