Display Stream Compression, is that it can be used by other cables and ports.USB-Cand Thunderbolt technologies leverage DisplayPort for their video and audio transmission in DP Alt Mode, and in turn, can make use of VESA DSC for greater resolution and refresh rate support. ...
DSC is a mathematically lossy, but visually lossless compression algorithm. That means that although there are some differences in the eventual image that is produced after the compression is applied, the human eye can’t really register it. It uses a range of encoding tools to achieve this but...

For everything over 8K at 60Hz, HDMI 2.1 usesDSC(Display Stream Compression), which is an effective form of data rate compression without any impact on the image quality. It increases latency, but the added delay is imperceptible (below 1ms). HDMI 2.1 Features Other features of HDMI 2.1 inc...
signals, but they differ in several ways. DisplayPort supports higher resolutions and refresh rates than HDMI, and also supports features like Multi-Stream Transport (MST) and Display Stream Compression (DSC). HDMI, on the other hand, is more widely used and supports features like ARC and CEC...
Display Stream Compression 1.2 With HDMI 2.1's new, higher bandwidth requirements, new methods of compression are required. The most common method of compressing video streams is a technology called Display Stream Compression (DSC). It was initially developed with computers in mind and couldn't enc...
Chroma subsampling is one of several compression techniques that can be used to reduce the overall bandwidth required to transmit video. For consumers, DSC has largely taken the place of chroma subsampling, as it is entirely visually lossless and unlocks the kind of additional bandwidth necessary fo...
The information for the DisplayPort (and so USB-C) means a bandwidth of 32 Gbps without Display Stream Compression (DSC). This means that 1440p @ 240 Hz RGB 8-bit can be transmitted with 98% bandwidth need. Whether this is actually available to you depends...

DisplayPort 1.4 was officially released in March 2016, maintaining the existing highest transmission capacity of the previous version (32.4 Gbps). Although it failed to establish new transmission modes, it introduced several notable features, including the incorporation of Display Stream Compression (DSC)...
