In a statement, James Choate, compliance program manager for VESA, said that DP40 and DP80 cables were enabled by "improvements in both the DisplayPort connector and cable design." The cables are also backward-compatible with other DisplayPort link rates, such as HBR 3 and 2. According to VESA, there are now DisplayPort and Mini DisplayPort DP40 and DP80 cables from companies including Accell, Bizlink, and WIZEN. There should eventually be UHBR-certified monitors and video sources, but today's announcement is only accompanied by UHBR-certified cables. Of course, it's possible that some products will still claim such performance without going through VESA's certification process, but UHBR certifications seem to be the only way to know for sure if the DisplayPort 2.0 product will give you that impressive bandwidth. Meanwhile, "DP40 UHBR" certification calls for support for a 10Gbps link rate (UHBR10) and a maximum throughput of 40Gbps via four-lane operation. VESA's new "DP80 UHBR" certification means the display, cable, or video source supports up to a 20Gbps link rate (what VESA calls UHBR20) and a throughput of up to 80Gbps via four lanes. The Ultra-high Bit Rate (UHBR) Certification is what you'll have to check for if you want to be certain about these figures. This enables extreme uses, like 16K resolution with display stream compression (DSC), 10K without compression, or two 8K HDR screens at 120 Hz.īut just because a monitor or cable, for example, is DisplayPort 2.0-certified doesn't mean that's the performance you'll get. The spec can support a max throughput of 80Gbps compared to DisplayPort 1.4's 32.4Gbps. VESA's latest certification is around DisplayPort 2.0. Technology certifications, like DisplayPort and HDMI, generally provide an overview of associated products' capabilities to give shoppers an idea of expected performance, like a monitor's max speed or cable's max bandwidth, before even using them. In case anyone wonders, I want to use the AVR to be my HDMI switch for all the gear instead of massive cabling behind the TV.VESA, which makes the DisplayPort spec, today announced a certification program aimed at helping consumers understand if a DisplayPort 2.0 cable, monitor, or video source can support the max refresh rates and resolutions the spec claims.
#HDMI 2.1 BANDWIDTH FULL#
So my question is, do we think that 2022 and all the vendors will come to their senses and go full 40/48 Gbps on all ports in their next line up? When I look at the current line up (at least the tiny info that vendors write in their spec) there are very few that has all HDMI ports with 40 Gbps. And hugging this forum and the reviews in search of next AVR is really therapy and test of my patients. The pandemic, factories filling up with water and all other negative things that has been going on that causes more ore less the entire technology industry and all affected to completely halt/slow down development as well as releases, slay brands due to poor sales is not helping either. I am in search of my next AVR and it’s a struggle. To my understanding the full bandwidth currently of sharing audio and video features in HDMI 2.1 (even 2.1a) would only require 40 Gbps of bandwidth.
