VGA and HDMI

Introduction of VGA

The VAG interface is the most common and common interface. The full name of VGA is the Video Graphic Array. VGA supports simultaneous display of 16 colors or 256 grayscales at a higher resolution of 640X480 and 256 colors at a resolution of 320X240.

The VGA interface is the interface that outputs analog signals on a video card, also known as the D-SUB interface. The VGA interface is a D-type interface with a total of 15 pins, divided into three rows of five in each row. VGA interface is the most widely used interface type in video CARDS.

The most extensive type of interface, most video CARDS come with this interface. It transmits red, green, blue analog signals as well as synchronous signals (horizontal and vertical signals) using VGA connection equipment, the length of the cable should not exceed 10 meters, and pay attention to whether the connector is firmly installed, otherwise it may cause virtual shadow in the image.

Introduction to HDMI interface

HDMI, the high-definition multimedia interface, is a fully digital image and sound transmission interface that can transmit uncompressed audio and video signals. HDMI can be used in set-top boxes, DVD players, personal computers, video games, integrated amplifiers, digital stereos and televisions. HDMI can transmit audio and video signals simultaneously, which greatly simplifies the system installation because audio and video signals use the same cable.

Because the DVI interface can handle hd resolution easily, gamers can also enjoy lossless HD image quality while playing games. But there are games out there that have a higher resolution than HD, so the HDMI port has an advantage.
