Answer four possible questions in HDMI HD line connection

The pressure of busy work and study makes watching TV one of the ways for office workers and student party to relieve pressure. In order to better visual effect and experience, many friends use HDMI HD cable, but there will be some problems in use.

1、 What if the interface does not match?

A friend thought of putting the HDMI video signal on the video receiving and display device, and found that the interface of the display device was VGA interface, which did not match. What should I do? HDMI to VGA converter can solve this problem perfectly. One end adopts standard HDMI male port and the other end adopts VGA female port, which has strong compatibility and is more convenient to use.

2、 When the device is switched on, the TV is color biased or there are snowflakes?

This may be due to the humidity caused by the HDMI interface of TV and computer being exposed for a long time without use, or poor contact caused by frequent plugging. It is recommended to replace other interfaces for testing.

3、 No response from TV after connection?

First, determine that the TV signal input channel is HDMI input, which can be selected according to HDMI cable and TV interface. The setting mode is menu input signal source interface.

Since the computer generally defaults to the display output separately, it should be set on the computer when switching video. Sometimes, the computer refresh rate should be adjusted to 60Hz, the resolution should be adjusted to 1024 * 768, and then the TV resolution should be set.

Setting method: right click the desktop mouse - properties - Settings - extended mode.

If it is a laptop, you need to switch the output screen to turn on and switch the second monitor. Some computers need to be shut down or restarted.

4、 When the expansion mode is selected, the desktop on the TV is only in the middle, and the screen is not covered?

When we choose the expansion mode, the resolution on the TV is 1920 * 1080. If the actual resolution of the picture on the computer desktop does not reach 1080p, the picture on the TV can only cover the screen in the middle.

HDMI version 2.0 supports 4K * 2K Ultra HD technology to create a 3dimax theater with large screen display, first-line connection and 60Hz refresh rate. High speed refresh lets you bid farewell to loading, frame dropping, black screen and other phenomena.

When purchasing HDMI HD lines, you should also check the type of equipment interface. If the standard HDMI plug at both ends does not match the micro HDMI interface.
