What’s Display Stream Compression (DSC)?

Display Stream Compression is a data compression technology developed by VESA to reduce the bandwidth and enable video interfaces to handle high resolution and high refresh rate video transmission.

DSC is now a common feature for most displays and is widely used in video transmission standards like DisplayPort 1.4 and HDMI 2.1. With DSC, these connectors become more capable. They can transfer for example 8K@120hz images or even up to 10K@120hz.

As the technology uses a special algorithm to identify patterns and compress redundancies, the compression is efficient, visually lossless, and will not affect viewers’ experience.
