What are the types of computer cables

Computer PC monitors involve many interfaces, including VGA, DVI, HDMI, USB, and DP. Some of these interfaces are also divided into different types and versions. Now let's talk about the types of computer cables.

　　VGA interface:

　　VGA interface is a common interface that we have been using since the CRT era. It is a color-difference analog transmission interface. The D-type port has 15 holes on it to transmit different signals. In addition, the VGA interface is also called a D-Sub interface.

　　Characteristics:

　　1. In theory, it can support 2048x1536 resolution picture transmission.

　　2. Because VGA is an analog signal transmission, it is susceptible to interference, and signal conversion is easy to cause signal loss.

　　3. At 1080P resolution, users can obviously feel the loss of the picture through the naked eye.

　　4. It is recommended to use the following monitors with 1080P resolution.

　　VGA is currently the most widely used display interface. Almost most of the low-end displays have a VGA interface, but because of its shortcomings, the high resolution cannot reach the refresh rate it should have, and only the image input has no sound input. Makes it difficult to have room to play in the high-end display.

　　DVI interface:

　　DVI (Digital Visual Interface). It is an interface standard introduced by the Digital Display Working Group (DDWG) in 1999 by Silicon Image, Intel, Compaq, IBM, HP, NEC, Fujitsu and other companies. The DVI interface is relatively complicated, mainly divided into three types, DVI-A, DVI-D and DVI-I. And DVI-D and DVI-I are divided into single-channel and dual-channel.

　　The above is an introduction to the types of computer cables. I hope that everyone will be helpful after understanding the types of computer cables.
