What is DP 1.4?
DP 1.4 (DisplayPort 1.4) is a display interface protocol used to transmit audio and video signals. It is the fourth version of the DisplayPort protocol, released in 2016, with significant improvements in performance and functionality compared to previous versions. The following is a detailed analysis of DP 1.4:
1. Main features
High bandwidth:
The maximum bandwidth of DP 1.4 is as high as 32.4Gbps (although the real effective bandwidth is 25.92Gbps), which provides users with higher bandwidth support to cope with higher-quality audio, video and graphics display needs.
High resolution support:
Supports up to 8K resolution (7680×4320 pixels) and 60Hz refresh rate, and each display can display two video streams simultaneously at 4K resolution. This allows users to enjoy a more detailed and smooth visual experience.
Color performance:
Introducing full-light range color to provide a more realistic and vivid image display. At the same time, it supports HDR (high dynamic range) technology, providing higher contrast and richer color expression. In addition, it also supports a maximum 12-bit color depth, which can present more realistic colors and more detailed images.
Multi-stream transmission:
Supports Multi-Stream Transport (MST) technology, which allows a single DisplayPort output signal to be divided into multiple sub-signals, each sub-signal can independently control a display. This provides greater flexibility and efficiency for multi-screen display and multitasking.
data compression:
Supports VESA's Display Stream Compression (DSC) technology, which can compress high-resolution video signals before transmission, effectively saving bandwidth resources.
Synchronization technology:
Supports Fixed Rate Link (FRL) technology and Adaptive Sync technology. These technologies help reduce video display stuttering and tearing and improve user viewing experience.
Built-in data encryption:
DP 1.4 also provides built-in data encryption to protect the security of sensitive data being transmitted.
2. Application fields
DP 1.4 lines are widely used in monitors, TVs, laptops and other fields. Its high-speed and stable data transmission capabilities allow users to enjoy a better visual experience and usage experience on these devices. For example, in the field of monitors, DP 1.4 lines can achieve a refresh rate of up to 60Hz, making the display smoother; in the field of TVs, many high-end TVs are equipped with DP interfaces, which can be connected to computers or other devices through DP 1.4 lines to watch HD movies or playing games; in the field of laptops, many high-end laptops are equipped with DP interfaces, which can be connected to large-screen monitors or projectors through DP 1.4 cables to achieve high-definition output.
3. Summary
To sum up, DP 1.4 is an advanced display interface protocol that provides high resolution, high refresh rate, high color fidelity and faster data transmission speed. It brings users a better visual experience and higher work efficiency, and is one of the important standards for modern multimedia transmission.
