HDMI HD cable application

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 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 need to be noticed by users.

In the current market, HDMI lines are very numerous, varied and varied. Cheaper is only 20 yuan a meter, expensive is a few hundred yuan a meter. Of course, the quality of these wires is also uneven. If you buy inferior wire for cheap, then HD will undoubtedly become empty talk! If you buy a few hundred yuan a meter of wire for HD, the investment seems to be too big. So, how can I buy a cheap and reliable HDMI cable?

Users only need to try it out at the time of purchase! But it should be noted that due to the high cost of HDMI cable, most HDMI displays do not come with HDMI cable. Consumers must add money to purchase original HDMI cables, or directly purchase HDMI cables from third-party channels. It should be noted that some inferior HDMI cables may have stable signals and clear pictures when used at lower resolutions.

But once you start transmitting HD video in 1080i/1080P format, the problem may appear immediately. For example, a large number of snowflakes or stripes appear on the image screen, which makes it impossible to watch normally. Or the quality of the displayed image is significantly reduced, and the clarity is greatly reduced. Therefore, when you test the quality of HDMI cable in actual combat, you must use real 1080P HD video with high resolution and high bit rate. In this way, after the trial, you can successfully buy the HDMI cable and complete the connection of the HDMI display.

How to complete interface conversion

Since the DVI interface can be converted to an HDMI signal by the conversion head. Because the HDMI interface can be backward compatible with the DVI interface. But at this time, you need an HDMI → DVI adapter cable to complete the interface conversion. The method of using this patch cord is very simple. You only need to connect the "big" DVI interface to the graphics card, and then connect the "small block" HDMI interface to the display. The screen transfer can be realized by turning on the power without any settings. However, it should be noted that such an approach wastes valuable resources of the HDMI display, and the picture quality is reduced during transmission. And your computer can't play HDCP copyrighted movies, or it's more cost-effective to spend five or six hundred dollars to buy a new HDMI graphics card.

HDMI connection skills

In most cases, an HDMI interface and an HDMI cable are required to connect an HDMI display device. It is a display device that uses an HDMI display as a game machine and a computer. Since both DVD players and game consoles have an HDMI interface, the HDMI display can be connected not only to a computer, but also to a home theater and game console. At this time, the rich interface behind the display can come in handy.

    Normally, 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 game console. When using HDMI displays together, it is important that we do not plug in the HDMI cable too often, as this can easily lead to wear and tear on 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, moisture and the like from entering the port.
