How many kinds of computer monitor cables are there?

The types of computer monitor connection cables mainly include:

1、VGA

The VGA interface is also called D-sub, 15 pin, which is divided into three rows and is an old-fashioned interface. Now it has basically begun to be eliminated. The VGA interface can hardly be found in the new graphics card. Basically, it is used on the integrated graphics card of old computers or new computers. VGA interface transmits 640x480 SD video signal by default, but actually supports 18.

2、DVI

DVI is relatively friendly, the full name is digital video interface, which minimizes the transmission of differential signals based on TMDS, and it was also the most common and basic display interface a few years ago. DVI-A used in the VGA analog era was first introduced, and then DVI-I with simultaneous analog and digital transmission was introduced. The latest one is DVI-D. Single channel supports the same resolution as dual channel, but the refresh rate is only half. Dual channel supports maximum 1080P 120hz and 2560 x 1600/60hz.

3、HDMI

HDMI is the most mainstream high-definition interface at present, which is called "high-definition multimedia interface". It can support video and audio. If your monitor has audio, you can realize audio transmission, such as LCD TV and some monitors that support audio. It is characterized by high resolution, small interface, no compressed audio stream and rich protocols. The earliest version of 1.0 was launched in February 2002, and the bandwidth was increased from 1.3/ 1.4 to 10.2Gbps.

4. Differential pressure

The abbreviation of DisplayPort is DP, which is a digital high-definition interface and compatible with the current mainstream HDMI interface. Both support one signal line to transmit video and audio signals at the same time. The bandwidth of DP interface has reached 10.8Gbps since the first generation, supporting 2560 x 1600 12bit output. At present, the most popular DP 1.2 has reached 2 1.6Gbit/s, surpassing HDMI2.0 and supporting 1080P 240, 2K 165, 4K 75 and 5K 30. DP 1.3 supports 2K 240, 4K 120 and 8K 30.
