I decided to prepare a separate article in which to tell in detail and show by example how to connect a TV to an ordinary stationary computer using an HDMI cable. The topic is relevant, and I am often asked about it. In fact, nothing is complicated. But there are some nuances that we will try to understand within 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 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 can be bought in every digital equipment store.
Why connect them? Everything is very simple. The TV can work as a monitor. That is, you can display the image from the computer on the TV screen. The TV can be used as a 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 image but also sound.
I myself, and other users, most often connect a PC to a TV to watch movies on a big screen, or to play. You can also connect a gamepad to your computer and play on the big screen. Some people use televisions instead of monitors. They work with documents, surf the Internet, etc. But it seems to me that this is not very convenient. 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 from different manufacturers: LG, Samsung, Sony, Philips, Panasonic, Ergo, Hitachi, etc. In the same way, there will be no big 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, you can do everything according to this article:.
Preparation: check the HDMI ports on the TV and computer, choose the cable
First, we need to check if our devices have the required ports. We also need an HDMI cable to connect. Let's take a closer look at everything. 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.
We connect the TV to the computer using an HDMI cable
You just need to take a cable, connect it to the HDMI output on your computer and to the HDMI input on your TV.
Important! Devices must be connected when they are off and power off. There is a risk of burning ports. There are such cases.
If you connect the TV as a monitor, that is, a single screen, then the circuit will look something like this:
Let's also consider another case when a TV and a monitor will be connected at the same time.
TV as a second monitor for PC
The monitor can also be connected via HDMI (as in my photo below), over DVI, or even over VGA. As a result, two screens will be connected to the PC.
We figured out the connection. Most likely, in your case there will already be a system unit with a monitor connected to it. And all that needs to be done is to connect another TV to it.
Select HDMI input as a signal source in the TV settings
Most often, after connecting and turning on the devices, there is no image on the TV. An inscription like "No signal", "No signal source selected" or something like that will appear. You need to select a signal source on the TV. The port where we connected the cable.
For 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 a 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 actual process may differ depending on the TV. I have an old LG.
An image from the computer should appear on the TV. This will be either a copy of what is displayed on the monitor (if any), or a clean 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 display mode. There are several of them.
Setting up an HDMI-connected TV in Windows
The screen resolution is adjusted automatically in most cases. 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 with a keyboard shortcut Win + P.
After clicking on them, the "Project" menu will appear. In the top ten it looks like this:
In Windows 7 like this:
Let's take a closer look at each mode.
In most cases, these settings are sufficient.
Additional screen options
To open them, just right-click on an empty area of \u200b\u200bthe desktop. In Windows 10, 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 the mode of operation (which I talked about above).
In Windows 7, the settings of a TV connected via HDMI look like this:
With the image setting on the computer sorted out.
What if the sound from the computer is not going to the TV?
This happens very often. The image appears on the TV, but there is no sound. It does not exist at all, or it sounds from a speaker system connected to the computer. If you want the sound to go through the TV, then the first thing to check is that the sound on the TV is not muted or twisted.
Your TV should be in the device list. 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 the TV still does not have sound from the PC, 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 have never encountered the problem of audio output via HDMI. How many I connected, everything worked immediately after connecting. But there is such a problem.
Connect 4k TV to computer. Ultra HD over HDMI
If you have an Ultra HD TV (aka 4k) and the video card supports this resolution, then there is a chance to get a beautiful and clear image. I checked, everything works. I have a 4k TV from Philips. And in the computer video card GeForce GTX 750Ti, which supports resolutions up to 4096x2160.
There are a lot of nuances. I'm not a gamer, so I'll try to explain as best I can. The fact is that you can display a 4k image via HDMI, and I did it. But most likely we will get a refresh 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 they use DVI cables to connect to 4k monitors. And I have not seen something in DVI TVs.
I connected everything, started up the computer, and saw that the image on the TV was somehow strange, wrong colors. Perhaps this is only in my case.
Everything can be solved very simply. First, I tried to disable UHD (Ultra HD) for the HDMI port to which the PC is connected in the TV settings. The image is normal, but the resolution is 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 became normal. The scale was also 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 think it's not real. Moreover, the video card on my computer is not the newest and most powerful.
I look forward to your comments. Ask questions and don't forget to share tips. Good luck!
The HDMI connection transfers multimedia data in good quality and high speed. Information is transmitted through special cables connected to two or more required devices. HDMI is the most popular digital interface and has replaced the old analog one. In this article, we will explain in detail everything about this type of connection and analyze how to enable it on a laptop.
The emergence of new digital interfaces such as HDMI contributed to the obsolescence of the previously used popular VGA. He not only transmitted the image at a lower quality, but also distorted it, which often caused difficulties in work. The connection in question has a large bandwidth and supports audio transmission.
In addition to HDMI, several other types of digital data transmission interfaces are popular - DVI and DisplayPort. They all have different connectors and some characteristics, which allows you to use the required connection for different situations. Read more about comparing these interfaces in our articles on the links below.
Varieties of HDMI cables
As mentioned earlier, the connection of two devices is made using special cables. They come in a variety of sizes, standards, and only support certain hardware. They also have different connector types and specifications. You can read more about this in our other materials.
Enabling HDMI
It is automatically enabled on all HDMI-compatible devices. Users only need to make a few simple settings so that the connection of the two devices is successful, and a clear picture and sound appears on the screen.
Usually, it is enough to change just a few parameters of the operating system and you can immediately start working on the equipment. For detailed instructions on connecting computers and laptops to a monitor via HDMI, read our articles on the links below.
Causes of HDMI malfunction
Sometimes there are problems in the operation of devices, this may also be due to the connection interface. When using HDMI, two problems are often observed - no picture and no sound. Incorrect device settings, outdated drivers or physical breakdowns are considered to be the main causes of malfunctions. In such cases, it is recommended that you resort to one of several methods for solving the problems encountered. Read more about them below.
Above, we examined in detail the main function of the HDMI interface, got acquainted with the types of cables, figured out how to turn on this connector on a laptop and talked about possible malfunctions. We hope our article was useful and you learned everything you need to know about connecting devices via the HDMI connector.
I welcome everyone! The "seven" has many of its own "proprietary" problems, which are not always within the power of ordinary users to deal with. But we will help you with this! So, the topic of today's tutorial is HDMI cable setup.
We'll look at how to connect the cable;
What settings in Windows need to be activated;
At the end of the article, a detailed video instruction.
After you connected the HDMI cable to the laptop / computer and the TV, right-click on the "Desktop" and select the line "Screen resolution" in the drop-down menu. By the way: at the moment when you 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 "," Resolution "and so on. Further, in the field "Multiple screens" set the function "Duplicate these screens". Now click on the "Apply" and "OK" button. Thus, you activate all the necessary settings for an adequate image.
Moving 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" - "Control audio 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". Below in the same window, you will see the "Speakers" option. Hover the cursor over the TV icon (just the TV, not the speaker) and right-click. A menu will drop out, in which we select the line "Use as default". Attention: if everything was done correctly, a green "bird" should appear in the window near the TV. If you want to turn off the sound, turn off in the "Speakers" window: right-click, select the line "Use as default" and click on it. Here's a strange pattern. However, this is how it works. Click "Apply" and "Ok". By the way, it's probably no longer a secret for you that you don't need to buy a gps navigator if you have an android phone, just
