With the continuous development of technology and the continuous integration of HDMI technology, it has been widely promoted in the LCD market, and the exposure rate is also higher and higher. When connecting HDMI monitors, users still need to pay attention to some details. HDMI interface is the mainstream high-definition interface, which is widely used in the current digital devices and high-definition display devices.

HDMI HD cable

In the current market, HDMI line is very many, various, various. The price is low, only 20 yuan a meter, more expensive is a few hundred yuan a meter. Of course, the quality of these wires varies. If we buy poor quality wires at a low price, HD will undoubtedly become empty talk! If you buy a few hundred yuan a meter high wire, the investment seems too big. So, how can we get a cheap and reliable HDMI line?

Users only need to buy, try and know! However, it should be noted that due to the high cost of HDMI cables, most HDMI displays do not include HDMI cables. Consumers must increase funds to purchase the original HDMI cable or directly purchase the third-party channel HDMI cable. It should be noted that some poor quality HDMI cables may have stable signals and clear images when used at low resolution.

But once the high definition video transmission in 1080i / 1080p specification starts, the problem will appear immediately. For example, a large number of snowflakes or stripes appear in the image, which makes it impossible to observe them correctly. If the image quality is obviously reduced, the definition will be greatly reduced. Therefore, high resolution and high bit rate 1080p HD video must be used when testing the quality of HDMI line in actual combat. In this way, after trial, you can purchase the HDMI cable and connect the HDMI monitor.

How to complete the interface conversion

Because the DVI interface can be converted into HDMI signal through the conversion head. Because HDMI interface and DVI interface are downward compatible. But at this point, an hdmidvi connection is needed to complete the interface conversion. The use of this transmission line is very simple. We just connect the "big" DVI interface to the video card, and then connect the "small" HDMI interface to the monitor. Without any settings, image transmission can be realized by starting the machine. However, it should be pointed out that this is a waste of valuable resources of HDMI display, and the image quality will be reduced during transmission. And your computer can't play HDCP movies, so it's more economical to buy a new HDMI card for 500 or 600 yuan.

Skills of HDMI connection

Connecting to an HDMI display device requires an HDMI interface and HDMI cable in many cases. HDMI displays are used as display devices for games and computers. Because DVD players and game consoles have HDMI interfaces, HDMI monitors can be connected not only to computers, but also to home theaters and game consoles. At this point, the rich interface behind the monitor will come in handy.

Typically, the DVI connector on the back of the monitor is used to connect to the graphics card in the computer, and the HDMI connector is used to connect to a DVD player or console. When both devices use the HDMI monitor, we should not plug in the HDMI cable too frequently, because it is easy to cause connector wear. In order to better protect the connector of HDMI wire, plastic cover should be installed on the connector when it is not in use to prevent dust, water vapor, etc. from entering the port.
