If you are about to purchase or have already purchased an HD TV, then you will certainly be faced with the need to choose an HDMI cable. How to connect an HDMI cable to a TV is an interesting question, but first you need to purchase a cable. This is not a very complicated procedure, but it is necessary to familiarize yourself with some of its nuances beforehand.
Brief characteristics of the HDMI cable
Before connecting an HDMI cable to a TV, it is important to understand their main characteristics. HDMI is a high definition multimedia interface. There are two types of HDMI cables: HDMI Standard and HDMI High Speed. Using HDMI Standard cables, TV receivers of all categories are connected: cable, terrestrial, satellite, including 3D, as well as conventional non-(3D) Blue-Ray players and most HD video cameras. Cables of this category may have different markings, except for High Speed. Gaming consoles, computers, Blue-Ray 3D players. Game consoles, computers, Blue-Ray 3D players are advisable, but not necessary, to be connected with a High Speed cable.
One of the main subtleties of choosing a cable is the requirement for its length, which should not exceed 5 m, otherwise the image quality may deteriorate sharply. Also, the cable must not be kinked. Before purchasing a cable, you need to decide what connectors are on your device. Relatively old models of TVs and other equipment usually have two types of connectors - RCA (otherwise called "tulip", cable with triple wiring) and S-video, a round output with 4 or 9 pins. Newer device models are equipped with an HDMI interface.
To connect the most efficient connection, you need to purchase a cable, which - on the one hand - has a connector on the device panel, and on the other hand - HDMI. Finding such a cable is quite problematic, and if this fails, you need to use adapters that can have two or more connectors of various types.
How to connect HDMI cable to TV
How to connect HDMI cable to TV? The TV must be turned off before connecting the cable. If the TV device has S-video, then the cable is connected with the S-video connector to the TV, and HDMI to the computer.
It is undesirable to connect an HDMI TV to the DVI connector of a computer. Such a connection will result in a significant reduction in picture and audio quality.
After cable connection HDMI TV and computer, the TV turns on first, and then the computer. While loading operating system on the computer, the TV screen flashes, indicating that it is connected to an external source. The TV must be switched to AVI mode, in which the signal to it will not come from external antenna but from a computer.
How to connect the HDMI cable to the TV if the TV is connected to the computer with the HDMI cable for the first time? A mandatory procedure is to configure the video card. To do this, you need to find the properties of the video card. When you enter the "Advanced" tab, you will find the instructions, following which you will get the image of the computer on the TV. In Windows 7, you need to go to the desktop in "Permission" - "Find". The TV device will be detected in the system and it will remain to mark it as the main monitor. If the TV is not detected, then you need to enter the properties of the video card again and repeat all the steps again.
In the properties of the video card, it is possible to adjust the resolution, desktop size, adjust the color and other settings.
If you experience image problems, it can be caused by both the HDMI cable and problems in the connected devices, most often caused by a software error.
To do this, inspect the connectors available on the device. If you cannot determine the types of ports by eye, find their description in the documentation for your computer. Depending on the device model, you can see the connectors of the following varieties:
- HDMI is a digital interface found on most modern computers. It transmits both audio and video, and therefore is optimally suited for outputting a multimedia signal to a TV.
- DVI is another digital port widely used in the market. Transmits only video, no sound.
- VGA is a popular analog connector. Like the previous port type, it only outputs video signal.
- Mini DisplayPort , Thunderbolt 2 , USB‑C and Thunderbolt 3 (USB-C) - digital interfaces, which are present in Apple computers. All of them transmit video and sound. In addition, the Mac can be equipped with an ordinary HDMI connector.
There are other types of connectors. But we have listed the most popular ones. Your device is probably equipped with one or more of them.
2. Determine which connectors for signal reception are on the TV
Look at the TV ports. Most modern models have HDMI and VGA connectors. Older ones are equipped with RCA format ports, the plugs for which are called tulips:
3. Select a cable according to the available connectors
If you have an HDMI TV
If both the TV and the computer have HDMI connector, then everything is elementary: you can connect devices using an HDMI cable. This option will be optimal.
To connect a computer that does not have an HDMI port to an HDMI TV, you will also need a special signal converter along with an HDMI cable. Which one depends on the connector available on the computer. These can be DVI → HDMI, VGA → HDMI or other adapters to HDMI.
In addition to the HDMI cable, you can often connect an additional audio cable to such converters, the other end of which is inserted into the computer. This allows you to transmit audio bypassing the limitations of DVI and VGA. An audio cable is often sold with a converter.
www.amazon.com To connect to a Mac HDMI TV with a Thunderbolt 2 or Mini DisplayPort connector, you will need a Mini DisplayPort to HDMI adapter along with an HDMI cable. For it to transmit sound, ask the store for such an adapter with audio support.
If you have a VGA TV
For a VGA TV, the procedure will be similar. Only you will need an HDMI → VGA, DVI → VGA or other converter, depending on the computer port. The main thing is that it converts the signal to VGA.
If you have an RCA TV
If you have a very old TV model with tulips at your disposal, then converters like HDMI → RCA, VGA → RCA and others that output an RCA signal are suitable.
In order not to make a mistake when buying a cable or converter, you can tell the seller the types of connectors on your TV and computer: he will select the appropriate option for you or check your choice for compatibility.
4. Connect devices via cable
Turn off your computer and TV beforehand for safety reasons. Next, connect the devices using a cable (and, if necessary, a converter). Only then turn on the devices. If the TV does not automatically detect the computer as the signal source, then do it yourself in the TV settings.
5. Adjust the picture on the TV using a computer
If the image is blurry, open system settings on the computer and find the partition responsible for the monitor. Here you can set the resolution that matches your TV and, if necessary, change the video display mode.
How to connect a computer to a TV via Wi-Fi
Modern smart TVs can be connected to computers wirelessly via local wifi network. Technologies like DLNA and WiFi Direct allow you to broadcast video, music and other content on a TV screen or completely duplicate the image from a computer on a TV, turning the latter into wireless monitor. And in the case of Wi-Fi Direct, you don’t even need a router for this.
For example, on LG devices for such functions there is a service. And Samsung TVs offer similar features as part of the AllShare service.
Settings wireless connection may differ depending on the manufacturer and model of the TV. Some devices establish a connection in a semi-automatic mode. Others require additional software to be installed on the connected computer.
Therefore, formulate universal instruction that suits all users is difficult. If you want to connect your TV to a computer via Wi-Fi, you will find the necessary information in the paper manual or on the official website of the manufacturer along with the software needed for this.
Watching movies or YouTube videos, playing video games, editing documents on a large display is much more pleasant. Especially when you consider that in our era, LCD TV is gaining more and more popularity. Connecting a computer to such a screen will not require too much effort. Next, we will look at how to connect hdmi to a TV from a computer. To do this, you only need to make sure that the necessary outputs are present on the devices and use the most convenient method for this.

Well, lovers of active computer games will feel all the realism of the ongoing actions on a large TV matrix.
In reality, positive aspects There are many applications for this combination of devices. And most often they relate to creating a comfortable working environment or entertaining the owner.
Connecting the TV to a personal computer or laptop, it becomes possible to:
Now most users are interested in the ability to view IPTV. After all, why spend money on cable TV or watch an uncertain reception of an on-air signal, if it is possible to contemplate your favorite TV channels for nothing from the official page of the television company? For this reason, the question more and more often arises: “how to connect a TV to a computer via an HDMI cable?”.
Requirements, at which it is possible to connect Personal Computer to TV screen:
The HDMI cable must be long enough. The assortment here is huge, there is even an opportunity to find a cable up to 20 meters in size. Often the LCD TV is placed on the wall. And therefore, for most users, if an HDMI cable is connected to a TV, this creates problems. Although there is a simple and convenient solution.
Look for a 90 degree angled HDMI adapter designed for this exact purpose. The direction and shape of its bend is different. For this reason, before purchasing this adapter, consider which side it will have an input and output.
It may also be that there is no HDMI output in the video adapter of the PC. Look for it above on the panel coming from motherboard, since the video card can be built into it. When there is no such port anywhere, then you will have to connect the PC to the TV in a different way. To do this, you need to find a DVI standard video output on your computer.
In this case, you will have to purchase an additional HDMI to DVI adapter. If other types of devices, such as a camera, are connected to the TV, they must have a mini-HDMI port. This applies to tablets as well as other compact devices.
Naturally, another cord is needed. For example, if the TV has only one HDMI port, and you need to connect many devices, such as: system unit, laptop, camera or other gadget. Then you need to buy an additional HDMI-switch. And using the remote control included in its kit, you can very conveniently change the video signal sources.

D. or 3D video signal.
Connecting a TV as a Monitor
Be careful! When connecting a PC, all devices must be turned off, otherwise the HDMI interfaces may be damaged. And with this outcome, there will no longer be an opportunity to view the video signal on TV, and in the worst case, the video adapter or TV board will burn out.
As an example, consider the Samsung UE55F6500 TV model. Pretty popular pattern. Basically, the connection procedure is the same for both expensive products and inexpensive ones.
Connect the HDMI cable to a suitable socket on the computer. In this case, the monitor is connected to the video card using the DVI output.
Samsung UE55F6500 has 4 HDMI port. We connect to one of them with a cable from the computer. We carefully control that the connections are quite tight. We start the TV and PC and see what happens on both screens.
Most likely, the inscription will appear on the TV matrix:
- "Cable not connected";
- "Weak signal or none";
- Check the computer's video signal and cable connection.
This problem needs to be fixed. First, use the TV remote control to switch the signal source using the “Source” button, it should be located at the top of the D.U. A menu will appear in which you need to select an item called “External”, and then select HDMI and press the OK button located in the center.
If you have connected and configured everything correctly, then the wallpaper on the desktop will be displayed on the TV screen. Windows desktop. If this does not happen, then the screen extension parameters are probably set incorrectly.
In this case, you must use the "screen mirroring" mode. To find and use it, you need:
For television matrices operating at a resolution of 1920 by 1080, a resolution of 1280 by 720 is allowed. However, in this state, the scales of icons, folders and files on the TV screen will become larger and will not be so convenient to work with.

- There is a picture on the monitor, but only the message "Cable not connected" is displayed on the TV.
- There is an image on two screens, but the TV has no sound.
Incorrect resolution problem
This problem may occur due to a mismatch between the TV video resolution settings and the settings on the monitor or laptop.
For example, you have an LG monitor that operates at a resolution of 1366 by 768, and a TV with a matrix that supports the characteristics of a 1920 by 1080 screen is connected. In this case, get perfect picture It will not work on two devices at once. Here it is necessary to decide what is more important in this moment. And set such screen parameters that will correctly display the picture on the device you have chosen.
Or purchase a monitor with the best performance, which can support Full H. D resolution. In this combination, an ideal image without distortion will appear on all screens at once.
No sound on the connected device
First reason
Cases where sound does not appear after connecting a computer to additional screen, are often. It must be remembered that with the help of an HDMI cable, not only video is output to the TV, but also an audio signal. And to view 3D videos, you need a 1.4 standard cable. However, most often this is a non-technical problem. Here the reason is the incorrect configuration of the operating system. To eliminate it, you need to perform the following actions:
After such actions, the audio signal will appear.
The second reason
Another reason for the unavailability of the audio signal is the lack of support for high-definition audio. To find out if there is such a function on the computer, and whether it is currently enabled, you need to go to "Device Manager". To do this, you need:
Third reason
When a TV has many HDMI ports, the default one labeled first must necessarily support digital transmission. sound signal. Other HDMI sockets may need to be configured. It all depends on the TV model.
To establish sound reception on other ports, you should look for necessary settings in the TV menu and set the desired mode.
Conclusion
In conclusion, it should be noted that it is not difficult to connect a computer to a TV. To do this, you just need to purchase an HDMI cable of the required length and find HDMI sockets on the paired devices. However, technical difficulties are generally quite rare. In most cases, you just need to understand how to properly configure OS Windows 7, as well as set the correct parameters in the TV menu.
