Friends! Everything you do on the computer, watch movies, cartoons, chat on Skype, play, view photos, slides or Internet pages in a browser, all this will be shown on the screen of your TV if the TV is connected to the computer via an HDMI cable. Nowadays, almost any TV has an HDMI input, and most produced video cards 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 it all on your TV. There are slides or photos, please look. I’m not talking about games, because I’m not a supporter of them; they take up 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, a not entirely new 4 series (LED type), purchased several 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 an Nvidia video card installed and also has an HDMI connector.
As I already said, our TV has two HDMI connectors. With the TV turned off, connect the HDMI cable to HDMI connector 2,
We connect the reverse end of the cable to the HDMI connector of the video card of the 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 this message: “The cable is not connected” “Check the cable connections and the 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.
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 our computer’s desktop 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 we can see in the window that appears, our main screen is set to the second (2) Samsung SyncMaster 971P monitor, and in the “Multiple Screens” parameter we have set “Display the desktop on only 2 monitors”, which is why the image is only present on the computer monitor screen, but it's not on the TV
We bring everything in this window to this state. Select a parameter
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 automatically be set to the same resolution of 1366 x 768. If not, then either the TV or 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 set the resolution on the TV correctly, otherwise why would I connect it then. I set the resolution to 1366 x 768 on my Samsung TV, the image is perfect.
And on a computer monitor this resolution of 1366 x 768 looks like this.
And nothing can be done here. If you want the perfect image on your TV and computer monitor, then they must support the same screen resolution, that is, have the same characteristics. There is no sound on the TV after connecting the TV to the computer via HDMI Friends! Don't 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 to Start->Control Panel->
Hardware and Sound->Sound
If you don’t have anything in this field, right-click on an empty space and in the menu that appears, check the “Show disabled devices” items. "Show connected devices"
Now we look at the name of our TV, in my case it is Samsung, we need to turn it on and turn off the rest. Right-click on Realtek and select Disable.
We also turn off the speakers.
Samsung – Enable, Apply and OK.
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 am often asked about it. In fact, it’s nothing complicated. But there are some nuances that we will try to understand in this article.
Almost every TV, even not the newest one, 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 can probably be bought in every digital equipment store.
Why connect them? It's very simple. The TV can work as a monitor. That is, you can display images from a computer on a TV screen. The TV can be used as the main or second monitor. This means that the image from the PC will be displayed on the screen of a regular monitor and TV at the same time. Or only on TV. It depends on your tasks. It should be noted that HDMI outputs not only images, but also sound.
I myself, and other users, most often connect a PC to a TV to watch movies on big screen, or for play. 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. And your eyes get tired faster. For permanent job It is better to use a monitor when using a computer. 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. Just as there will be no significant 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, select a cable
First we need to check if our devices have the necessary ports. To connect we also need HDMI cable. Let's look at everything in more detail. If you have everything, then you can proceed directly to 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 the HDMI input on your TV.
Important! Devices must be connected when they are turned off and the power is off. There is a risk of burning the ports. There are such cases.
If you connect the TV as a monitor, that is, a single screen, then the diagram will look something like this:
Let's also consider another case when a TV and monitor are connected at the same time.
TV as a second monitor for a PC
The monitor can also be connected via HDMI (like mine in the photo below), via DVI, or even via VGA. As a result, two screens will be connected to the PC.
We sorted 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 the devices, there is no image on the TV. A message like “No signal”, “No signal source selected” or something like that will appear. On the TV you need to select the signal source. The port where we connected the cable.
To do this, your TV remote must have separate button"SOURCES", or "INPUT".
After clicking on it, a menu should open in which you can select the signal source. You can see which port on your TV you connected the cable to (each port has its own number). Or simply select an active source. The process itself may vary depending on the TV. I have an old LG.
The image from the computer should appear on the TV. This will be either a copy of what is displayed on the monitor (if there is one), or a blank desktop (expand).
The main thing is that the picture from the computer appeared on the TV screen. Next, in the Windows settings we can change the image output mode. There are several of them there.
Setting up an HDMI-connected TV in Windows
The screen resolution is adjusted automatically in most cases. So in Windows settings we can only change the multi-display mode. 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 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 the top ten it looks like this:
In Windows 7 like this:
Let's look at each mode in more detail.
In most cases, these settings are quite sufficient.
Additional screen options
To open them, just right-click on an empty area of the desktop. In Windows 10 you need to select "Display Settings", and in Windows 7 - "Screen Resolution".
A settings window 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 operating mode (which I talked about above).
In Windows 7, the settings of a TV connected via HDMI look like this:
We figured out how to set up the image 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’s not there at all, or it sounds when it’s connected to the computer. speaker system. If you want the sound to come through the TV, then first check that the sound on the TV is not muted or distorted.
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 the 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 start the installation. At this moment, let the HDMI cable be connected to the computer.
I showed how to check these settings in Windows 7 in the article. Be sure to watch it and read the comments. There is a lot of useful information there.
I have never encountered a problem with audio output via HDMI. No matter how many times I 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 a 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 the computer has a GeForce GTX 750Ti video card, 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 it is possible to output a 4k image via HDMI, and I succeeded. But most likely we will get a frame refresh rate of 30 Hz. Which is very little. To get 60 Hz, we need a video card with HDMI 2.0 and the same cable. This is why DVI cables are used to connect to 4k monitors. But I haven’t seen anything on DVI TVs.
I connected everything, started the computer, and saw that the image on the TV was somehow strange, the colors were wrong. Perhaps this is only in my case.
Everything is resolved very simply. First, I tried in the TV settings to disable UHD (Ultra HD) 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 became normal. The scale was also automatically set to 300%. Otherwise everything would be very small. It can be changed if necessary. I haven't tried playing at this resolution. But I think that this is not real. 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 tips. Best wishes!

Question: HDMI connection: The monitor keeps turning off and then turning on again
please tell me: asrock h170 pro4 motherboard with built-in video card. The monitor can only be connected via avg+HDMI adapter, because... The motherboard only has an HDMI connection. There is no video card. The monitor keeps turning on and off. When connected to a TV, the same thing happens.
The cable is working fine: I connected it to the laptop via HDMI - everything worked. Fine. (used 2 cables: AVG+HDMI, HDM+HDMI).
P.S. tell me how to fix it? M. payment 2 days. At the same time, I brought it from the service center - after a complete diagnosis. There was a manufacturing defect, they said the Bios was completely reset, the rest was said to be normal. Monique and the TV flicker every 1-2 seconds, and you can’t really see anything in the BIOS either. constant flickering.
Answer: magirus, if only they charged me for diagnostics - which should be free. Although they wrote what the reason was on the receipt. You'll have to go to them again.
All PPC, Windows is loading, it starts flickering every second and the inscription appears on Monica: Out of Rage! - and no longer loads.

Correction, video is built into the processor. I didn’t take a video card, so I connected the Monica via MP.
Hi all. The following problem arose: when I start the system unit, the speaker starts beeping continuously for 10-15 seconds, then it reboots and continues in a circle. In this case, no signal is sent to the monitor. I tried to run without RAM and listen to the speaker signal. The speaker signal is a different beep, but the system still reboots. And sometimes the speaker beeping may not even occur when I changed the RAM slots and it did. I tried resetting the BIOS, it didn't help. I started it without a processor, the motherboard does not reboot in this case. I tried to install another processor, the speaker still beeps and reboots.
Relatives brought the system unit and said that the computer went out while playing Skyrim. Just like that. I hope I explained everything clearly)

Tomorrow I'll try to get another power supply. There were other motherboards at home. I used them to check the performance of the power supply. I connected the power supply and tried to start it without RAM to find out the functionality of the board. Without RAM, the speaker began to squeak, after connecting the RAM, the squeaking stopped and that was it. Although I’m not sure about the functionality of these boards, since they are old, and they also refuse to show the image on the monitor(

Guys, thank you all. I identified the problem) It was a RAM issue. When I removed the plate the signals simply changed.
Today I borrowed a working RAM from a friend and checked it. Everything worked)
Question: The difference between the integrated graphics core of the processor and the graphics card built into the motherboard
Hi all!
Please explain the difference between the integrated graphics core of the processor and the video card built into the motherboard.
I still have a few questions about this (all of the below assumes you don't have a discrete graphics card).
1. As I understand it, in order for the motherboard to have ports for video output, it must have a built-in video card. Or not necessarily?
2. Is it possible to display video on the monitor if there is only integrated. graph. core in the processor (no video card in the motherboard)?
3. Will performance increase in the presence of both an integrated graphics core in the processor and a video card built into the motherboard?
Thank you all so much in advance for your time.

1. As I understand it, in order for the motherboard to have ports for video output, it must have a built-in video card. Or not necessarily?
In order to display images from these ports, you need to have an integrated graphics core in the processor or on the motherboard.

2. Is it possible to display video on the monitor if there is only integrated. graph. core in the processor (no video card in the motherboard)?
Possibly, if the motherboard supports image output from the processor core graph.
Message from thedriveee
3. Will performance increase in the presence of both an integrated graphics core in the processor and a video card built into the motherboard?
Modern Intel does not have integrated devices on the board, everything is in processors. I don’t know whether it’s possible to use the built-in percentage and the one on the board together on AMD. I think not. The integration on the board is very weak. You can only get a picture from them, nothing more.

Question: 3 monitors at the same time - VGA + HDMI + laptop monitor
Hi all.
Very often, laptops have two connectors for image transmission, VGA and HDMI. The question is, is it possible to work simultaneously on a laptop monitor and two connected monitors?
I tried to connect two VGA monitors using this scheme, one via an HDMI adapter, but only two work at the same time. Tried it on two different laptops, on two different OS (Windows 7, Winodws 10).
Perhaps someone knows how to make three monitors work simultaneously?

Using a connection via the HDMI interface, multimedia data is transmitted in 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 analogue one. In this article we will tell you in detail everything about this type of connection and figure out how to enable it on a laptop.
The emergence of new digital interfaces such as HDMI was facilitated by the obsolescence of the previously popular VGA. Not only did it render the image with lower quality, but it also distorted it, which often caused difficulties in work. The connection in question has a large throughput and supports audio transmission.
In addition to HDMI, several other types of digital data transfer 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 at the links below.
Types of HDMI cables
As mentioned earlier, the connection of two devices is made using special cables. They come in different sizes, standards and only support certain equipment. In addition, they have different types connectors and specifications. You can read more about this in our other materials.
Enabling HDMI
On all devices that support HDMI connection, it is automatically enabled. Users only need to complete a few simple settings so that the connection of the two devices is successful, and a clear picture and sound appear on the screen.
Usually it is enough to change just a few operating system parameters and you can immediately start working on the equipment. Detailed instructions For information on connecting computers and laptops to a monitor via HDMI, read our articles at the links below.
Causes of HDMI failure
Sometimes malfunctions occur in the operation of devices; this may also be due to the connection interface. When using HDMI, two problems are often observed - lack of image and sound. The main causes of malfunctions are considered to be incorrect device settings, outdated drivers or physical failures. In such cases, it is recommended to resort to one of several methods for solving the problems that have arisen. Read more about them below.
Above, we examined in detail the main function of the HDMI interface, became familiar with the types of cables, figured out how to enable 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 an HDMI connector.
