1. Introduction: What are HDMI and DP?
Let's explore HDMI (High-Definition Multimedia Interface) and DP (DisplayPort), two major standards used for digital display connections. While both technologies provide a way to transmit audio and video signals, they have different features and purposes, allowing users to make the right choice based on their needs.
What is HDMI?
HDMI is an interface that transmits high-quality video and audio signals through a single cable. It is commonly used in home AV devices such as TVs, Blu-ray players, and gaming consoles.
What is DP?
DP is a digital display interface developed by VESA (Video Electronics Standards Association). It was originally designed for computer and monitor connections. DP offers advanced features compared to HDMI and is particularly preferred for high-performance applications like PC gaming.
