Answer: HDMI, DVI, VGA, DisplayPort

A: The VGA interface is also known as the D-Sub interface. The VGA interface adopts a 15-pin pin-type structure and adopts an analog protocol, which is the interface used by many old graphics cards, notebooks and projectors.

Answer: Due to a series of problems such as wire and signal interference, VGA can generally only reach 1200p resolution when used, and the fonts are easy to be blurred at high resolution. If the signal line is long, the image will be smeared.

Answer: There are DVI-A, DVI-D and DVI-I on the DVI interface, which can be divided into single channel and dual channel. The DVI-A (DVI-Analog) interface only transmits analog signals. The DVI-D (DVI-Digital) interface is a purely digital interface and is not compatible with analog signals. DVI-I (DVI-Integrated) interface, compatible with both DVI-I and DVI-D plugs, compatible with digital and analog signals. Their connectors are shaped differently and cannot be plugged in if the connectors do not match.

Answer: "Single-channel DVI interface: 1920*1200@60Hz Dual-channel DVI interface: 2560*1600@60Hz, 1920*1080@120Hz"
