But in that article, we analyzed all possible connection methods from the most ancient interfaces (VGA, tulips) to the most modern HDMI. But times are changing and today HDMI is the most advanced interface that is present in all modern TVs and which is used most often. Therefore, today we will dwell on this in more detail. We will deal with the connection, as well as with possible problems.

So, how to connect a TV to a computer via HDMI

The first thing we need is to make sure that this interface is available on both devices - TV and computer (or laptop), looks like this:

Their prices vary greatly, both on the length of the cable itself and on the quality of workmanship (the material from which it is made, etc.). I took the cheapest cable 3.3 meters (price is about $ 4) it shows everything perfectly, even high-resolution files - 1080p shows without any jambs. See for yourself which cable to take. And of course, do not forget about the length so that it is not too short.

We connect this cable to the computer (laptop) and to the TV. As a rule, LCD TVs have several HDMI inputs - connect to any, there is not much difference. And on the TV, select the HDMI source. Samsung has a separate HDMI button for this, or press SOURCE (other manufacturers should have something similar):

and select the desired source, depending on which slot number you inserted into, you select it:

Next, let's deal with setting up a computer.

If you connect the TV to the computer as the main monitor, then it should be automatically detected. If you connect the TV as an additional monitor, then most likely you will have to configure something. As a rule, there are no problems, everything is quite simple and quickly set up, the system is still more modern, but it doesn’t always work out so smoothly. But now let's try to figure it out for different versions of operating systems.

So the setting for Windows 7

Right-click on the desktop and select "Screen Resolution":

The following window will appear:

And here, in the "Multiple screens" field, select the mode you need. You can either duplicate the image on both the main and additional monitor (TV) or Expand, that is, in other words, enlarge the screen on the right side or leave only one of the screens active. Here you yourself choose all the modes in turn, and see what's what. And after you select the desired mode, click "Apply" for the changes to take effect, and then confirm your action again by clicking "Save Changes" in the pop-up window:

For laptops running Windows 7, things are even easier. To select the appropriate display mode, you just need to press the key combination Fn + F4 (perhaps in some models it will not be F4, but another button, the main thing is to see that something like a monitor is displayed, as in the screenshot below, there may also be other characters or slightly different picture):

After pressing the combination of these keys, you will see the following window:

And alternately pressing F4, while holding Fn, select the desired mode.

This seems to have been sorted out. Here, in principle, problems should not arise, but with Windows XP, as I said, everything is not so simple. Firstly, in the case of a laptop, XP simply does not understand the Fn + F4 key combination, I don’t know why, but I couldn’t make friends with this Windows with these hot keys. Secondly, in the case of a computer, it is also far from always possible to set up an additional screen (in our case, a TV) through the screen settings, so you have to get into even more jungle. But, there are no hopeless situations, so now let's look at how to solve the problem of connecting a TV to a computer running Windows XP.

Connection setup for Windows XP

First, we try to set up the connection through the screen settings. Right-click on the desktop and select "Properties", and then go to the "Settings" tab:

And in this window, you can select your TV as the main screen by selecting screen 2 and checking the box next to "Use this device as the main one" or you can Extend the desktop by selecting the appropriate item below. Then click "Apply". And close this window. But, unfortunately, it is not always possible to set up a TV connection to a computer in this way. And if nothing works for you, move on.

If all of the above methods do not suit you, then the only option left is to configure the connection through the utility of your video card. And here, unfortunately, I won’t tell you a single recipe, since everyone has their own hardware, someone has Intel, someone has Nvidia, someone has Radeon, someone has a newer video card, someone is older, accordingly, these utilities will be different, but the principle is very similar, only the exact name will differ, and the general meaning will naturally be the same. I will show on the example of Nvidia, but I will repeat for others - all actions are similar.

So, right-click on the desktop and select "NVIDIA Control Panel":

And in the window that opens, click on the plus next to the “Display” item to expand the entire contents of the section and go to the “Installing multiple displays” item:

and in the right part of the window, select the desired mode and click "Apply". If one of them does not work, choose another. As a rule, the "Clone" mode works without problems.

Well, that's all. All I could say. If you still can’t connect the TV to your computer via HDMI, then ask in the comments, I’ll try to advise something sensible.

And that's all. I say goodbye to you. Good luck to all. And see you soon on the blog.

With respect, Roman
