  Display Stream Compression, a lossy compression algorithm optimized for the specific use case of device-display transfers (i.e. relatively low compression ratio == very high quality that's claimed to imperceptible even if it can't run lossless, not needing to work on full frames for speed/sub-frame latency, ...)

  I didn't know either. DSC is Display Stream Compression, and has been part of the spec since 1.4. According to Wikipedia [0], > DSC is a compression algorithm that reduces the size of the data stream by up to a 3:1 ratio.... Using DSC with HBR3 transmission rates, DisplayPort 1.4 can support 8K UHD (7680 × 4320) at 60 Hz or 4K UHD (3840 × 2160) at 120 Hz 0: https://en.wikipedia.org/wiki/DisplayPort#1.4 https://en.wikipedia.org/wiki/DisplayPort#1.4
