HDMIインターフェースは主流のHDインターフェースです, which is widely used in the current digital equipment and high-definition display equipment. And with the continuous development of technology, the continuous integration of HDMI technology has made it popular 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 users need to pay attention to.
In the current market, HDMI cable is very many, uneven, wide variety. The cheap ones only cost 20 yuan a meter, and the expensive ones cost several hundred yuan a meter. Of course, the quality of these wires is also uneven. If in order to buy cheap inferior wire, then high-definition will undoubtedly become empty talk! If you buy a wire of a few hundred yuan a meter for HD, the investment seems to be too big. So, how to buy a cheap quality and reliable HDMI cable?
Users only need to try it out when they buy! However, it should be noted that due to the high cost of HDMI cables, most HDMI displays do not come with HDMI cables. Consumers must add money to buy the original HDMI cable, or directly buy the HDMI cable from a third-party channel. It should be noted that some inferior HDMI cables may be stable and have a clear picture when used at a lower resolution.
But as soon as you start streaming 1080i/1080P HD video, problems can arise immediately. For example, a large number of snowflakes or stripes appear in the image screen, resulting in abnormal viewing. Or the image quality of the display is significantly reduced, and the clarity is greatly reduced. Therefore, when we test the quality of the HDMI cable in actual combat, we must use the real 1080P high-definition video with high resolution and large bit rate. In this way, after the trial, you can successfully buy a good HDMI cable and complete the connection of the HDMI display.
How to complete interface conversion
Because the DVI interface can be converted to HDMI signal through the converter head. Because the HDMI interface can be backward compatible with the DVI interface. But at this time, you need an HDMI→DVI conversion cable to complete the interface conversion. The method of using this adapter cable is very simple, just need to connect the “big” DVI port to the graphics card, and then connect the “small” HDMI port to the display. Without any Settings, you can switch on the screen transfer. However, it should be noted that this approach wastes some of the valuable resources of the HDMI display, and the picture quality will be reduced in transmission. And your computer can’t play HDCP copyrighted movies, or spend five or six hundred dollars to buy a new HDMI graphics card is more cost-effective.
The use of HDMI connection skills
In most cases, connecting an HDMI display device requires an HDMI port and an HDMI cable. The HDMI display is used as a display device for both game consoles and computers. Since 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 display comes in handy.
Normally, the DVI port on the back of the monitor is used to connect to the graphics card in the computer, and the HDMI port is used to connect to the DVD player or game console. When the HDMI display is used by both devices, we must not unplug the HDMI cable too often, because it is easy to lead to wear of the connector. In order to better protect the connector of the HDMI cable, when not in use, a plastic protective cover should be placed on the connector to prevent dust, water vapor, etc., from entering the port.
