DisplayPort Introduction

The DP interface not only supports high-quality video transmission but also has the capability to transmit audio, USB data, and other forms of data. This versatility makes the DP interface an indispensable part of the modern digital world.

It is worth mentioning that the design of the DP interface is intended to gradually replace traditional VGA, DVI, and LVDS interfaces. Through active or passive adapters, DP can achieve backward compatibility with traditional interfaces such as HDMI. This means you can easily connect various types of devices without worrying about compatibility issues. This makes the DP interface an ideal choice for modern digital connectivity, providing users with more options and greater flexibility. Whether in home entertainment systems or commercial applications, DP has demonstrated its outstanding performance and convenience.
