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

HDMI HD cable

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

Users just 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 their funds to purchase the original hdmi cable, or directly purchase a third-party channel hdmi cable. It is worth noting that some poor quality HDMI cables may have stable signals and clear images when used at low resolutions.

But once high-definition video transmission in the 1080 i/ 1080p specification starts, problems start immediately. For example, a large number of snowflakes or streaks appear in the image, which makes it impossible to observe them properly. If the image quality is significantly reduced, the sharpness is greatly reduced. Therefore, when testing the quality of the HDMI cable in actual combat, it is necessary to use high-resolution, high-bitrate 1080p high-definition video. In this way, after the trial, you can smoothly buy an HDMI cable and complete the connection of the HDMI display.

How to complete interface conversion

Because DVI interface can be converted to HDMI signal by converter head. Because the HDMI interface is backward compatible with the DVI interface. But at this point, an HDMIDVI connection is needed to complete the interface conversion. The way to use this transmission line is extremely simple, we just connect the "big" DVI port to the graphics card, and then connect the "small" HDMI port to the display. Without any Settings, the image transfer can be achieved by turning on the machine. However, it should be pointed out that this is a waste of valuable resources for HDMI displays, and the quality of the image will be reduced during transmission. And your computer can't play HDCP copyrighted movies, so it's more economical to spend 0 or 0 on a new HDMI graphics card.

The use of HDMI connection skills

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

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