HDMI HDL interface can provide up to 5Gbps data transmission bandwidth, and can transmit uncompressed audio signal and high resolution video signal. At the same time, there is no need to carry out digital analog or analog-to-digital conversion before signal transmission, which can ensure the highest quality audio-visual signal transmission. How can the computer connect the TV with HDMI high-definition display line?

First of all, you need to have a TV that supports HDMI HD display line input and a computer with a graphics card and HDMI HD display line output. If the computer does not have HDMI HD display line output, DVI output can also be used, but a DVI to HDMI HD display line adapter is needed.

Then we need an HDMI HD display line with an appropriate length. It is recommended not to use a HDMI HDL with a length of more than 10 meters. It is difficult to ensure that a pure HDMI HD display line (without special circuit enhancement) can continue to support the high resolution of 1920x1080 when it exceeds 10 meters.

Finally, it is the connection. Just plug one end of the HDMI HD display cable into the HDMI HD display cable of the computer graphics card for output, and plug the HDMI HD display cable of the TV into the other end. Turn on the computer and LCD TV, and use the remote control to adjust the "signal source" of LCD TV to "HDMI HD display line mode". After changing to HDMI HD display line signal, the TV will display the picture transmitted by the computer, and the sound and image of the computer can be displayed on the TV.

If the TV picture is not displayed due to the resolution mismatch, the resolution of the picture can be set on the computer to achieve the best display effect on the TV. Right click on the computer desktop to pop up the menu and click "display settings". Click "advanced display settings" on the right.

In the resolution setting option, set the monitor to TV. Then the computer will automatically detect and recommend the best resolution, you can adjust the resolution according to the actual effect of the TV display to achieve the best display effect.

Next, set the TV as the default speaker of the computer to synchronize the picture and sound. Find the loudspeaker shaped volume icon in the computer taskbar, right-click and click "play device".

In the "play" settings, select TV "FTV", right-click and select "set as default device". Click "OK" and the TV can be used as a computer speaker.

In this way, the computer image and sound are connected to the TV successfully, and then you can play video on the computer to test the effect.
