HDMI is the global standard today for high-definition video with rich stereo audio. HDMI stands for High-Definition Multimedia Interface, a standard for transmitting digital video and audio signals from a source to a display.
HDMI signals are transmitted digitally in an uncompressed format. The result is superior picture quality and sound. Originally developed by a consortium of electronics manufacturers, HDMI has become the de facto standard for connecting consumer audio/video components.
Laptops, PCs and computer monitors sometimes include a choice of HDMI or DisplayPort ports. For all applications up to and including 4K/60 Hz, HDMI and DisplayPort can be considered equivalent interfaces and you can use either one. If you are a gamer looking for a high-resolution image and very low latency, DisplayPort might have a slight advantage.
