Product Information

Color depth of 10 bpc (30 bit/px or 1.07 billion colors) is assumed for all formats in these tables. This color depth is a requirement for various common HDR standards, such as HDR10. It requires 25% more bandwidth than standard 8 bpc video. DisplayPort cables differ in their transmission speed support. DisplayPort specifies seven different transmission modes (RBR, HBR, HBR2, HBR3, UHBR 10, UHBR 13.5, and UHBR 20) which support progressively higher bandwidths. Not all DisplayPort cables are capable of all seven transmission modes. VESA offers certifications for various levels of bandwidth. These certifications are optional, and not all DisplayPort cables are certified by VESA.

That means the DisplayPort 2.0 vs. HDMI 2.1 battle is over before it's even started. As far as intergenerational gains go, DisplayPort 2.0 vs. DisplayPort 1.4 is enormous, and should mean that DisplayPort 2.0 becomes the high-end cable for gaming PCs for years to come. When will it be available?Update, October 18, 9:42 a.m. ET: After this article published, a VESA spokesperson responded to Ars' request for comment, informing us that VESA will no longer certify products for DisplayPort 2.0. This enormous bandwidth makes it possible for a DisplayPort 2.0 connection to handle 4K resolution at 240Hz, 5K at 180Hz, and even 8K at up to 85Hz – all without using DSC. HDR content reduces these maximums slightly, but it can still do 8K at 60Hz even with HDR enabled.

Achieving greater alignment between DisplayPort and USB on a common PHY has been a particularly important effort within VESA given the significant overlap in use case models between the DisplayPort and USB4 ecosystems,” Alan Kobayashi, VESA board chair and DisplayPort Task Group chair, said in a statement.

I have not compared switch latency to Display Port, so would be curious if anyone here has impressions

Now based on Thunderbolt 3 signalling, DisplayPort 2.0 shares many characteristics with Thunderbolt 3, including the need for active cabling with transceivers at both ends to achieve the full 77-odd Gbps of payload bandwidth. Using an existing passive cable, bandwidth is reduced to 40Gbps with a usable payload of 38.7Gbps. DSC can provide up to a 3:1 compression ratio by converting to YCgCo and using delta PCM encoding. It provides a "visually lossless" (and sometimes even truly lossless, depending on what you're viewing) result. Using DSC, 8K 120 Hz HDR is suddenly viable, with a bandwidth requirement of 'only' 42.58 Gbps.
