The results of this testing indicated that DSC met the visually lossless criteria set by VESA. VESA members also concluded subjective testing as a far more robust method to verify visually lossless quality rather than using objective metrics, such as, PSNR which typically designates one value for an image. Overall, observers completed nearly 250,000 subjective image comparisons. The evaluation included a statistically significant number of observers who viewed many images over four image categories including artificial engineered images, text and graphics, such as street maps or different examples of printed material, people, landscape, animals and stills. For the final DSC codec, the visual performance of DSC was evaluated through clinical testing by VESA in collaboration with member companies. This testing was used to fine tune the DSC codec (coding / decoding algorithm). DisplayPort 2.1 enables up to 3X increase in video bandwidth performance (max payload of 77.37 Gbps)ĭuring the development of DSC, the contributing VESA member companies performed ongoing visual tests to uncover visual compression artifacts using different image types and image motion.Support for visually lossless Display Stream Compression (DSC) with Forward Error Correction (FEC), HDR metadata transport, and other advanced features.Advantages of DP 2.0 are enjoyed across both the native DP connector as well as the USB Type-C connector.Improved user experience with augmented/virtual reality (AR/VR) displays, including support for 4K-and-beyond VR resolutions.Improved support for multiple display configurations.Higher refresh rates and high dynamic range (HDR) support at higher resolutions.Two 4Kx4K (4096×4096) displays (for AR/VR headsets) and 30 bpp 4:4:4 HDR (with DSC) When using only two lanes on the USB-C connector via DP Alt Mode to allow for simultaneous SuperSpeed USB data and video, DP 2.0 can enable such configurations as:Three 4K (3840×2160) displays and 30 bpp 4:4:4 HDR (with DSC). Three 4K (3840×2160) displays and 30 bpp 4:4:4 HDR (no compression)
