I decided to prepare a separate article in which I will tell in detail and show with an example how to connect a TV to a regular desktop computer using an HDMI cable. The topic is relevant, and I often get asked about it. In fact, nothing is difficult. But there are some nuances that we will try to understand in the framework of this article.

Almost every, not even the newest TV, has at least one HDMI input. And in the computer, on the back panel of the system unit there is an HDMI output. This means that we can easily connect a PC to a TV using a regular HDMI cable, which you can probably buy in every digital equipment store.

Why connect them? Everything is very simple. TV can work as a monitor. That is, you can display an image from a computer on a TV screen. The TV can be used as the main monitor or as a second monitor. This means that the image from the PC will be displayed on the screen of a conventional monitor and TV at the same time. Or just on TV. It already depends on your tasks. It should be noted that HDMI outputs not only the image, but also the sound.

I myself, and other users, most often connect a PC to a TV to watch movies on big screen, or for playing. You can also connect a gamepad to your computer and play on the big screen. Some people use TVs instead of monitors. They work with documents, surf the Internet, etc. But it seems to me that this is not very convenient. Yes, and the eyes get tired faster. For constant work at the computer, it is better to use a monitor. And connect the TV to watch movies, photos, games, etc.

The connection process will be the same for TVs different manufacturers: LG, Samsung, Sony, Philips, Panasonic, Ergo, Hitachi, etc. Just like there will not be strong differences in Windows settings. Yes, the settings in Windows 10, Windows 8, Windows 7 are slightly different, but not critical. I'll show you everything.

If you have a laptop, then you can do everything according to this article:.

Preparation: check the HDMI ports on the TV and computer, select the cable

First we need to check if our devices have the required ports. We also need an HDMI cable to connect. Let's look at everything in more detail. If you have everything, then you can go directly to the connection and configuration.

If you have ports on both devices and have a cable, then you can connect.

Connect TV to computer with HDMI cable

Simply take a cable, plug it into the HDMI output on the computer and the HDMI input on the TV.

Important! Devices need to be connected when they are turned off and the power is off. There is a risk of burning ports. There are such cases.

If you connect the TV as a monitor, that is, the only screen, then the diagram will look something like this:

Let's also consider another case when a TV and a monitor are connected at the same time.

TV as a second monitor for PC

The monitor can also be connected via HDMI (like mine in the photo below), DVI, or even VGA. As a result, two screens will be connected to the PC.

We figured out the connection. Most likely, in your case it will already be system unit with a monitor connected to it. And all you need to do is connect a TV to it.

Select HDMI input as signal source in TV settings

Most often, after connecting and turning on devices, there is no image on the TV. There will be an inscription like "No signal", "No signal source selected" or something like that. On the TV, you need to select the signal source. The port where we connected the cable.

To do this, your TV remote control must have a separate "SOURCES" or "INPUT" button.

After clicking on it, a menu should open in which you can select the signal source. You can see which port on the TV you connected the cable to (each port has its own number). Or just select an active source. The process itself may differ depending on the TV. I have an old LG.

The image from the computer should appear on the TV. This will either be a copy of what is displayed on the monitor (if any), or a blank desktop (expand).

The main thing is that the picture from the computer appeared on the TV screen. Further, in the Windows settings, we can already change the image output mode. There are several of them.

Setting up an HDMI-connected TV in Windows

Screen resolution in most cases adjusts automatically. So in the Windows settings, we can only change the mode of operation with multiple displays. This is only relevant when a monitor and TV are connected to the PC. If there is only one display, then these settings are not needed.

The easiest way to change the mode in Windows 10, Windows 8 and Windows 7 is a keyboard shortcut Win+P.

After clicking on them, the "Project" menu will appear. In ten it looks like this:

On Windows 7 like this:

Let's look at each mode in more detail.


In most cases, these settings are sufficient.

Additional screen options

To open them, just click right click mouse over an empty area of ​​the desktop. In Windows 10, you need to select "Display Settings", and in Windows 7 - "Screen Resolution".

A window with settings will open, where you can see how many screens are connected to the computer.

You can also define them (by clicking on the "Define" button), change the resolution of each screen and operation mode (which I mentioned above).

In Windows 7, the settings of a TV connected via HDMI look like this:

We figured out the image settings on the computer.

What to do if the sound from the computer does not go to the TV?

This happens very often. The picture appeared on the TV, but there was no sound. It is not there at all, or it sounds from the connected to the computer speaker system. If you want the sound to go through the TV, then first check if the sound on the TV is muted or twisted.

Your TV should be in the list of devices. You need to right-click on it and set "Use as default".

If the TV is not in the list, then right-click on an empty area and check the boxes next to two items: "Show disconnected devices" and "Show disconnected devices".

If this does not help, and there is still no sound from the PC on the TV, then try reinstalling the video card driver. Just download it and run the installation. Let the HDMI cable be connected to the computer at this moment.

How to check these settings in Windows 7, I showed in the article. Be sure to watch it and read the comments. There is a lot of useful information there.

I've never had a problem with HDMI audio output. How many connected, everything worked immediately after connection. But there is such a problem.

Connecting a 4k TV to a computer. Ultra HD over HDMI

If you have an Ultra HD TV (aka 4k) and your video card supports this resolution, then there is a chance to get a beautiful and clear image. I checked, everything works. I have a Philips 4K TV. And in the computer video card GeForce GTX 750Ti which supports resolutions up to 4096x2160.

There are a lot of nuances there. I'm not a gamer, so I'll try to explain as best I can. The fact is that you can output a 4k image via HDMI, and I did it. But most likely we will get a frame rate of 30 Hz. Which is very little. To get 60Hz, we need a video card with HDMI 2.0 and the same cable. That is why DVI cables are used to connect to 4k monitors. And I haven’t seen anything on DVI TVs.

I connected everything, started the computer, and saw that the image on the TV was some kind of strange, wrong colors. Maybe it's just in my case.

Everything is solved very simply. First, I tried to disable UHD (Ultra HD) in the TV settings for the HDMI port to which the PC is connected. The image became normal, but the resolution turned out to be normal, 1920x1080. Therefore, this method is not very suitable for us.

To get a real 4k image with natural colors, you just need to change the screen resolution to the maximum 3840x2160 in the display properties in Windows 10.

The image immediately returned to normal. The scale was automatically set to 300%. Otherwise everything would be very small. It can be changed if necessary. I have not tried to play at this resolution. But I don't think it's realistic. Moreover, the video card on my computer is not the newest and not the most powerful.

I look forward to your comments. Ask questions and don't forget to share your tips. Good luck!

I welcome everyone! The "seven" has many of its "branded" troubles, which are not always easy for ordinary users to deal with. But we will help you with this! So, the topic of today's lesson is setting up an HDMI cable.

  • We will look at how to connect the cable;

  • What settings in Windows need to be activated;

  • Detailed at the end of the article Video instruction.

After you have connected HDMI cable to a laptop / computer and TV, on the "Desktop" right-click and select the line "Screen resolution" in the drop-down menu. By the way: at the moment when you have connected the cable, you will see a window in which the “Screen Settings” field and a circle divided into two parts, with numbers 1 and 2. Set the settings in the required fields, such as: “Screen ”, “Permission”, etc. Next, in the "Multiple screens" field, set the "Duplicate these screens" function. Now click on the "Apply" and "OK" button. So you activate everything necessary settings for an adequate image.

Let's move on to the sound settings on the TV: these settings are made on the computer! Click on "Start" - "Control Panel". In the system settings window that opens, select the "Hardware and Sound" item. Click on it and select the options "Sound" - "Manage sound devices". By clicking on it, you get a separate "Sound" window. In this window, you should see the icon of the TV connected to the computer, for example "Samsung". A little lower in the same window you will see the "Speakers" option. We move the cursor over the TV icon (namely the TV, not the speaker) and click the right mouse button. A menu will pop up, in which we select the line "Use by default". Attention: if everything was done correctly, then a green “bird” should appear in the window near the TV. If you want to turn off the sound, then turning off is done in the "Speakers" window: right-click, select the "Set as default" line and click on it. Here is such a strange pattern. However, that's exactly how it works. Click "Apply" and "OK". By the way, it's probably not a secret for you that gps navigator you don’t have to buy if you have an android phone, you just need

I answer all questions in detail.
Friends! Everything that you do on your computer, watch movies, cartoons, chat on Skype, play games, view photos, slides or Internet pages in a browser, all this will be shown on your TV screen if the TV is connected to the computer via an HDMI cable. Now, almost every TV has HDMI input, and most of the video cards produced have an HDMI output.
The HDMI interface was invented in order to connect two high-tech digital devices(they are undoubtedly your computer and TV) and transfer information from device to device without loss of quality. Such transmitted information can be an image and multi-channel high-quality sound. If you have a movie or cartoon on your computer, in any HD, Blu-ray or AVI, MOV, MPG, MP4 format, then you can watch all this on your TV. There are slides or pictures, please see. I'm not talking about games, because I'm not a supporter of them, they take a lot of time from young people, which can be spent on studying. We connect the TV to the computer via HDMI with a second monitor To connect the computer to the TV, we will use an HDMI cable, it looks like this and can be up to 20 meters long, choose the cable of the length you need.

For example, let's take a Samsung TV, not quite a new 4 series ( LED type), bought a few years ago, but it already has two connectors for connecting HDMI devices.

The computer that we will use to connect to the TV was also purchased about three years ago, it has Nvidia graphics card and also with an HDMI connector.

As I said, our TV has two HDMI connectors. With the TV turned off, connect the HDMI cable to HDMI connector 2,

The reverse end of the cable is connected to the HDMI connector of the video card desktop computer. The computer, in turn, is already connected to the monitor (also Samsung SyncMaster 971P) with a DVI cable.

We turn on the computer and TV. There may not be an image on the TV right away, instead we see such a message “Cable is not connected” “Check the cable connection and source parameter” or “ Weak signal or no signal"

On Samsung TVs, to display a list of all available video sources, you need to press the Source button on the remote control (Source).

A menu appears on the TV, in this menu, using the remote control, select the HDMI 2 connector,

Now, on our TV, an exact copy of the desktop of our computer should appear. But again there is nothing, the same error appears on a black screen. So we go to the "Screen Resolution" settings. Right-click on the desktop and select Screen Resolution.

As you can see in the window that appears, we have the second (2) Samsung SyncMaster 971P monitor set as the main screen, and in the “Multiple screens” parameter we have set “Display the desktop only on 2 monitors”, which is why the image is present only on the screen of the computer monitor, but it's not on TV


We bring everything in this window to this state. Choose an option
Multiple screens: "Duplicate these screens"
In the "Screen" parameter, "Multiple monitors" is automatically set, click Apply and OK.

The desktop of our computer appears on the TV.

The resolution of our small Samsung TV is 1366 x 768. If your computer monitor supports this resolution, then it will be set to the same resolution of 1366 x 768 automatically. If not, then either the TV or the monitor will have the wrong resolution. For example, my Samsung SyncMaster 971P monitor has a maximum resolution of 1280x1024. When using a TV and a computer monitor at the same time, the main thing for me is to correctly set the resolution on the TV, otherwise why did I connect it then. I exhibit on Samsung TV 1366 x 768 resolution, picture perfect.

And on a computer monitor, this resolution of 1366 x 768 looks like this.

And nothing can be done here. If you need perfect image on a TV and a computer monitor, then they must support the same screen resolution, that is, have the same characteristics. No sound on TV after connecting TV to computer via HDMI Friends! Do not forget that the HDMI interface transmits video and sound over one cable and we can specify in the settings operating system use the TV's built-in speakers to output sound.
Let's fix the problem by using a TV instead of a monitor. Go Start->Control Panel->

Hardware and Sound->Sound

If you don’t have anything in this field, right-click on an empty spot and in the menu that appears, check the items “Show disabled devices”. "Show connected devices"
Now we look at the name of our TV, in my case it is Samsung, you need to turn it on, and turn off the rest. Right click on Realtek and select Disable.

Turn off the speakers too.

Samsung - Enable, Apply and OK.

An HDMI connection transfers multimedia data to good quality and high speed. Information is transmitted through special cables connected to two or more necessary devices. HDMI is the most popular digital interface and has replaced the old analog one. In this article, we will tell you in detail everything about this type of connection and analyze how to enable it on a laptop.
