The HDMI interface is currently the mainstream high-definition interface, and is widely used in current digital devices and high-definition display devices. And with the continuous development of technology, the continuous integration of HDMI technology has made it popularized in the liquid crystal display market, and the exposure rate is getting higher and higher. When it comes to connecting HDMI displays, there are still some details that require the user's attention.

In the current market, the HDMI cable is very numerous, varied, and varied. Cheaper is only 20 yuan a meter, expensive is a few hundred dollars a meter. Of course, the quality of these wires is also uneven. If you buy cheap wire rods for cheaper prices, there is no doubt that HD will become empty talk! If you buy a few hundred yuan a meter of wire for high-definition, the investment seems to be too much. So, how can we buy a cheap and reliable HDMI cable? Users only need to try it out at the time of purchase. However, it should be noted that most HDMI displays do not come with an HDMI cable because of the high cost of HDMI cables. Consumers must add money to purchase original HDMI cables or directly purchase HDMI cables from third-party channels. It should be noted that some poor quality HDMI cables may have stable signals and clear pictures when used at lower resolutions. However, once the 1080i/1080P HD video is started to be transmitted, the problem may appear immediately. For example, there are a large number of snowflakes or stripes on the image screen, which makes it impossible to watch normally. Or the quality of the displayed image is significantly reduced and the definition is greatly reduced. Therefore, we must use real 1080P HD video with high resolution and high bit rate when testing the quality of HDMI cable in actual combat. In this way, after the trial, you can successfully buy an HDMI cable and complete the HDMI monitor connection.

How to complete the interface conversion

Because DVI interface can be converted to HDMI signal through the conversion head. Because the HDMI interface can be backwards compatible with the DVI interface. But at this time, you need a HDMI → DVI cable to complete the interface conversion. The method of using this adapter cable is very simple, only need to connect the "big" DVI interface to the graphics card, and then connect the "small header" HDMI interface to the monitor. Without any settings, start up the screen transmission. However, it should be noted that such practices have wasted some of the precious resources of the HDMI display and the picture quality will be reduced during transmission. And your computer can not play HDCP copyright movies, or spend more than five or six hundred dollars to buy a new HDMI graphics card more cost-effective.

HDMI connection tips

In most cases, connecting an HDMI display device requires an HDMI interface and an HDMI cable. It is a display device that uses the HDMI display as a game machine and a computer. Since both DVD players and game consoles have HDMI interfaces, HDMI displays can connect not only to computers, but also home theaters and game consoles. At this time, the rich interface behind the monitor can come in handy. Usually, the DVI connector on the back of the monitor is used to connect the graphics card in the computer, and the HDMI connector is used to connect a DVD player or a game console. When using the HDMI display with both devices, we must not unplug the HDMI cable too often, as this can easily lead to joint wear. In order to better protect the connector of the HDMI cable, when not in use, a plastic protective sleeve should be put on the connector to prevent dust, water vapor, etc. from entering the port.

In short, the current technology and development trend, HDMI interface has the tendency to replace other high-definition interfaces.
