Introduction to the HDMI interface of the monitor: The HDMI interface of the monitor is a fully digital video and sound transmission interface, which can send uncompressed audio and video signals at the same time. Only one HDMI cable is required for use, which greatly reduces the difficulty of installation and use. HDMI interface is the current mainstream interface, generally in set-top boxes, DVD players, personal computers, TVs, game consoles, integrated amplifiers, digital audio and TV sets are equipped with HDMI interfaces
Monitor VGA interface introduction: The VGA (Video Graphics Adapter) interface of the monitor is an interface that uses analog signal transmission, and is also the common name of the D-Sub interface; the VGA interface has a total of 15 pins, divided into 3 rows with 5 holes in each row, which is the most widely used in the previous graphics card. Interface type, now eliminated by the mainstream HDMI switch 5 in 1 out splitter
The difference between HDMI interface and VGA interface is as follows: 01. The HDMI interface is a digital interface; the VGA interface is an analog interface 02. The HDMI interface supports simultaneous transmission of digital audio and video. If the monitor is a TV, only one HDMI cable is needed to connect it; 1 additional wire is required to connect 03. HDMI interface is anti-interference during signal transmission; VGA interface is easily interfered by other signals during signal transmission 04. The HDMI interface supports 4K high-definition resolution; the VGA interface will be distorted at high resolution, and the fonts and pictures are a bit virtual Which one is better, HDMI or VGA interface: Both HDMI interface and VGA interface are a format of video signal transmission. HDMI interface supports synchronous transmission of audio and video. VGA interface is easily interfered by other signals, does not support synchronous transmission of audio and video, and is easy to be distorted at high resolution, so relatively speaking , When wiring, we generally choose the HDMI interface first, and then choose the VGA interface. If it is at 1920*1080p resolution, the general image difference is not very large, and the interface can be selected according to the actual situation; in general, the display HDMI and Which VGA interface is better? HDMI interface is better than VGA interface.
