Nvidia revealed the GeForce GTX 1080, the world's first graphics card with DisplayPort 1.4 support on 6 May 2016. [115] AMD followed with the Radeon RX 480 to support DisplayPort 1.3/1.4 on 29 June 2016. [116] The Radeon RX 400 series will support DisplayPort 1.3 HBR and HDR10, dropping the DVI connector(s) in the reference board design.
DSC version 1.2 was released on 27 January 2016 and is included in version 1.4 of the DisplayPort standard; DSC version 1.2a was released on 18 January 2017. The update includes native encoding of 4:2:2 and 4:2:0 formats in six-pixel containers, 14/16 bits per color, and minor modifications to the encoding algorithm.
USB4 Version 1.0 only defines how to tunnel DP connections according to the DisplayPort 1.4a specification (up to HBR3 speeds). USB4 Version 2.0 updates this support to the full DisplayPort 2.1 specification (up to UHBR20 speeds). Notably, the USB4 specification explicitly carves out needing to support the UHBR13.5 DP speed, even if UHBR20 is ...
[18] [19] They also stated: "Legacy interfaces such as VGA, DVI and LVDS have not kept pace, and newer standards such as DisplayPort and HDMI clearly provide the best connectivity options moving forward. In our opinion, DisplayPort 1.2 is the future interface for PC monitors, along with HDMI 1.4a for TV connectivity".

DisplayPort 2.0 can support higher than 8K resolution at 60 Hz losslessly due to new UHBR 10, 13.5, and 20 signaling standards (DSC 1.2 used in DisplayPort 1.4 for that resolution is not lossless) in 8 bit and 8K 60 Hz with 10 bit color and use up to 80 Gbit/s (effective bandwidth 77.37 Gbit/s), which is double the amount available to USB data ...
This is wrong as neither DisplayPort uses logic levels of 3.3 V (see above) nor does HDMI use 5 V logic levels. They both use differential signaling where the exact differential voltages aren’t specified, but are both way below 1 V. --Lukas.fink1 21:26, 1 March 2024 (UTC) Hi, thanks for the observations. Will review later today.
The 1280 × 1024 resolution is not the standard 4:3 aspect ratio, instead it is a 5:4 aspect ratio (1.25:1 instead of 1. 3:1). A standard 4:3 monitor using this resolution will have rectangular rather than square pixels, meaning that unless the software compensates for this the picture will be distorted, causing circles to appear elliptical.
