What are the important features of DisplayPort 2.1?

DisplayPort 2.1 allows a maximum bandwidth of up to 80 Gbps (depending on transport mode), is forward compatible with previous DisplayPort standards, and supports DSC (Display Stream Compression) and MST (Multi Stream Transport ).





  • DisplayPort 2.1 enables up to 3X increase in video bandwidth performance (max payload of 77.37 Gbps)

    • Maximum link rate to up to 20 Gbps/lane and features more efficient 128b/132b channel coding, delivering a maximum payload of 77.37 Gbps

    • First standard to support 8K resolution (7680 x 4320) at 60 Hz refresh rate with full-color 4:4:4 resolution, including with 30 bits per pixel (bpp) for HDR-10 support

  • Beyond 8K resolutions

  • Higher refresh rates and high dynamic range (HDR) support at higher resolutions

  • Improved support for multiple display configurations

  • Improved user experience with augmented/virtual reality (AR/VR) displays, including support for 4K-and-beyond VR resolutions.

  • Advantages of DP 2.0 are enjoyed across both the native DP connector as well as the USB Type-C connector

  • Support for visually lossless Display Stream Compression (DSC) with Forward Error Correction (FEC), HDR metadata transport, and other advanced features

 



 

Example Configurations:

  • Single display resolutionsOne 16K (15360×8460) display @60Hz and 30 bpp 4:4:4 HDR (with DSC)
    One 10K (10240×4320) display @60Hz and 24 bpp 4:4:4 (no compression)

  • Dual display resolutionsTwo 8K (7680×4320) displays @120Hz and 30 bpp 4:4:4 HDR (with DSC)
    Two 4K (3840×2160) displays @144Hz and 24 bpp 4:4:4 (no compression)

  • Triple display resolutionsThree 10K (10240×4320) displays @60Hz and 30 bpp 4:4:4 HDR (with DSC)
    Three 4K (3840×2160) displays @90Hz and 30 bpp 4:4:4 HDR (no compression)

  • 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 @144Hz and 30 bpp 4:4:4 HDR (with DSC)
    Two 4Kx4K (4096×4096) displays (for AR/VR headsets) @120Hz and 30 bpp 4:4:4 HDR (with DSC)
    Three QHD (2560×1440) @120Hz and 24 bpp 4:4:4 (no compression)
    One 8K (7680×4320) display @30Hz and 30 bpp 4:4:4 HDR (no compression)
