Safety precautions cannot be neglected. Any manipulations with devices must be performed before de-energizing them. It is better to completely unplug the power cables from the outlet; for the computer, you can simply turn off the power supply with the corresponding button.

USB connection

The USB connection method of the computer is only suitable for TVs that have an HDMI port. If you take a USB to USB cable and connect devices with it, then nothing will happen. For this method, you will need to purchase a special converter – an external video card that runs from the computer’s USB port. You will also need an HDMI cable.

  1. you need to connect the USB cable of the converter to the corresponding port on the computer;
  2. Connect the HDMI cable to the converter, and the other end to the TV;
  3. it remains to select the signal source, in this case it will be the HDMI connector to which the HDMI cable is connected.

This method can be done through a USB to VGA converter. However, it will not work to transmit sound over a VGA cable. You will either have to pull the jack 3.5 wire directly from the computer, or buy a converter to which you can connect both cables at once.

How to connect a computer to a TV with an HDMI cable

Perhaps this is the most popular and easiest way to connect a TV to a computer. It uses only one cable, transmits both video and audio, and the quality of data transfer is one level higher than that of alternatives.

HDMI connector
Before you start connecting, you need to make sure that both devices have an HDMI port. Usually on TVs it is located on the side, occasionally in the back of the device.

A computer could have multiple HDMI ports, but one could come from the motherboard and the other from a discrete graphics card. If you have a discrete graphics card, you need to connect to it. But if it is not there, then you can connect it to the motherboard. The only difference is what will be involved during the data transfer. If you have everything you need, then you can proceed to the connection process. Step-by-step instruction:

  • connect the first end of the cable to the HDMI input on the TV;
  • the second end to the HDMI input on the computer;
  • select the desired port in the TV settings.

Connecting a TV to a computer via hdmi

HDMI must be long enough. The maximum length at which there will be no signal loss is 10 meters. However, in some situations, the length can be increased to 20-30 meters. To increase even more, you will need to use either external amplifiers or a wire with an already built-in amplifier.

VGA

The VGA interface was previously the connection standard. But even today, monitors and TVs are equipped with an input for this type of connection. Since some computers do not have other outputs, which is especially true for older models, this option may be the only way to display an image on the screen.
How to connect a computer to a TV wirelessly and via cableAlmost every TV has the ability to connect via VGA. You need to find the output on the computer, and the input on the TV. Step-by-step instruction:

  • connect VGA input and output with a cable;
  • you need to make sure that it sits tightly;
  • tighten the screws on the sides, this mount will not allow you to accidentally pull out the wire;
  • It remains to select the signal source in the TV settings.

Special attention should be paid to the process of choosing a cable. VGA also has a maximum length at which it will function properly. For a resolution of 1920×1080 it will not exceed 8 meters, but for 640×480 it can reach 50 meters. As already mentioned, VGA does not support audio transmission, like HDMI, so you have to look for a solution to the problem. The simplest thing is to use computer audio equipment, or use the same 3.5 jack, but its maximum length does not exceed 3 meters.

How to connect a computer via DVI to Smart TV

If for some reason your computer does not have an HDMI port, you can use a DVI to HDMI cable. Almost every computer has a DVI connector, but not on a video card.

Giants such as NVIDIA or AMD have long abandoned DVI and VGA. Some motherboards that support integrated graphics still have a DVI connector, but this is only a matter of time.

As for TVs, there are usually no DVI inputs, since more modern connection options have long been replaced. The most reliable and easiest way to connect via DVI is to purchase a special adapter. You can also use a DVI to HDMI cable.
How to connect a computer to a TV wirelessly and via cableBoth interfaces can transmit high-quality signals in Full HD resolution. DVI also supports audio transmission. Step-by-step instruction:

  1. connect a part of the DVI cable or adapter to the appropriate connector on the computer;
  2. insert the other end into the TV;
  3. select the HDMI port as the signal input.

Older TVs have a DVI port, so you can connect directly with a DVI to DVI cable. However, in this case, no sound will be transmitted. Only with the use of a special adapter to HDMI, it is possible to transmit sound from the DVI output.

How to connect a computer to a TV wirelessly via Bluetooth

Usually, it is a laptop that is connected via Bluetooth technology, since not all computers support Bluetooth without a special adapter. This is convenient, because you do not need to buy and look for meters of wires. And you can also connect wireless headphones to watch a movie on the big screen and not disturb anyone. This method is more reliable and durable than a wired connection. They can tear, damage entry ports, or simply fail. However, to use this technology, the TV must support Bluetooth. You can check the availability of this function in the TV sound settings. If the technology is present, it will be possible there, for example, to find a sound output device.

Connectors for RCA wires are not available on the computer, therefore, in order to connect the computer in this way, you need to purchase a converter. The modern way to connect to a video card is an HDMI interface. Therefore, it is advisable to buy an HDMI to RCA converter. Of course, you can use a VGA to RCA converter, but in this case you will not be able to transmit the audio signal.
How to connect a computer to a TV wirelessly and via cableThe converter needs power. Usually, a mini USB to USB cable is included with which you can power the device. It is enough just to insert the USB into a free connector on the computer, and then the other end into the power port of the converter.

  • yellow – video signal output;
  • red – left audio channel;
  • white – right audio channel.

Step-by-step instruction:

  • connect the HDMI cable to the input of the converter, and the other end to the computer’s video card;
  • on the other side of the converter, connect tulips corresponding in color;
  • insert the power cable into the device, and the second part into a free USB port on the computer;
  • it remains to connect the tulips to the TV itself, this happens in the same way, you need to insert a wire of the corresponding color into the desired connector.

How to connect a computer to a TV wirelessly and via cable   The converter may be powered by a single HDMI cable, so in some cases it may not be used. Also on the body of the device is a switch that is responsible for the color standard. You can try different options to find the best one.
