DisplayPort 2.1 bumps that way up to 4K 480Hz using Display Stream Compression (DSC), or 8K 165Hz with compression. The 2.1b variant that is included with Nvidia 50-series cards and was announced at CES supports longer cables for UHBR20, which stands for Ultra-High Bit Rate at 20Gb/s per-lane, with four lanes on tap for up to 80Gb/s of bandwidth.

Dec 27, 2024 · DisplayPort 2.1 is crucial for supporting higher resolutions and refresh rates on PC monitors, such as 4K@360Hz HDR monitors. DisplayPort 2.1 includes three tiers: UHBR10, UHBR13.5, and UHBR20, which feature a max bandwidth of …

Jan 11, 2023 · Display Stream Compression (DSC), providing visually lossless compression and opening the door to significant improvements in resolutions and refresh rates. VESA has invested extensively in visual quality studies through York University to prove that DSC is truly visually lossless not only for SDR but for HDR content.

Oct 13, 2023 · It introduces the Panel Replay (PR) and Display Stream Compression (DSC) technologies, designed for reducing power consumption in high-bandwidth video transmission, and further enhancing video transmission capabilities respectively.

Feb 23, 2024 · You will still use DSC on the DP 2.1 because the GPUs are not there yet (not even the next gen RTX 5K series). The bandwidth needed for 4K 360Hz is almost 110Gbit/s which exceeds by far the limit of 80Gbps that's in DP 2.1 UHBR20. Therefore you will still use DSC!

Jan 7, 2025 · The current HDMI 2.1 standard supports up to 10K@120Hz using Display Stream Compression (DSC) and 8K@60Hz without DSC.

Jan 14, 2025 · VESA announced the 2.1b version of DisplayPort (DP) in January 2024 and now Nvidia has showcased the GeForce RTX 5090 Add-in board (AIB) which will have three DP 2.1b ports as well as an HDMI 2.1b output. Nvidia has lagged behind in DP support compared to AMD over the last year or so.

Dec 12, 2023 · Both DisplayPort 2.1 and DisplayPort 1.4 are backward compatible with all previous versions of DisplayPort. This table summarizes the key differences between DisplayPort P 1.4 and DisplayPort 2.1: Cadence has a very mature Verification IP solution.

Nov 12, 2022 · Full bandwidth is especially important as DSC feature on HDMI 2.1 FRL ports has not been widely supported on TVs or projectors until most recent models. All devices in a chain need to support DSC for compressed signal pipeline to work.

Jan 6, 2025 · What are the resolution/refresh rate limits of displayport 2.1b with and without dsc? What are the important features of DisplayPort 2.1? DisplayPort 2.1 enables up to 3X increase in video bandwidth performance (max payload of 77.37 Gbps)
