  The HDMI interface of the monitor is a fully digital video and sound transmission interface that can send uncompressed audio and video signals at the same time. It only needs one HDMI cable to use, which greatly reduces the difficulty of installation and use. The HDMI interface is the current mainstream interface. Generally, set-top boxes, DVD players, personal computers, TVs, game consoles, integrated amplifiers, digital audio and TVs are equipped with HDMI interfaces.
  The monitor VGA (Video Graphics Adapter) interface is an interface that uses ana-log 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. It was the most widely used interface type on graphics cards in the past, but has now been eliminated by the mainstream.
  The difference between the HDMI and VGA interfaces of the monitor
  The differences between the HDMI interface and the VGA interface are as follows:
  01. The HDMI interface is a digital interface; the VGA interface is an ana-log interface
  02. The HDMI interface supports synchronous transmission of digital audio and video. If the monitor is a TV, only one HDMI cable is needed to connect; the VGA interface does not support synchronous transmission of audio and video. When using, the video needs to be connected with 1 VGA cable and the audio needs another cable to connect
  03. The HDMI interface is anti-interference during signal transmission; the VGA interface is easily interfered by other signals during signal transmission
  04. HDMI The interface supports 4K high-definition resolution; the VGA interface will be distorted at high resolution, and the font and picture will be a little blurry
  Which is better, the HDMI or VGA interface of the monitor
  The HDMI interface and the VGA interface are both formats for video signal transmission. The HDMI interface supports synchronous transmission of audio and video. The VGA interface is easily interfered by other signals, does not support synchronous transmission of audio and video, and is easily distorted at high resolution. Therefore, relatively speaking, when wiring, we generally give priority to the HDMI interface, and then choose the VGA interface. If it is at a resolution of 1920*1080p, the general image difference is not very large, and you can choose the interface according to the actual situation.
  In general, the HDMI interface is better than the VGA interface.
