October 18, 2022

VGA and HDMI ports are widely used for POS system to connect the second display. Both of them are digital signal transmission standard, but what’s the difference?

VGA stands for Video Graphics Array, which is introduced by IBM in 1987. Lots of PC manufacturers are conventional to VGA, so it became the standard for all PCs. But it is only for transmitting video signals, nothing else. it’s not suits for some high-resolution applications and cannot transmitting audio signals.

HDMI stands for High-Definition Multimedia Interface. It was designed by some famous electronic product manufacturers like Hitachi, Sony, Toshiba, etc. The audio and video signals can be transmitted by one cable simultaneously. It integrated audio and video into a single digital interface in audiovisual devices. It is the core technology of High bandwidth digital content core protection and digital visual interface.
