Fast charging & Data transfer
As technology innovation marches forward, new kinds of devices, media formats, and large inexpensive storage are converging. They require significantly more bandwidth to maintain the interactive experience users have coe to expect. In addition, user applications demand a higher performance connection between the PC and these increasingly sophisticated peripherals. Super Speed USB addresses this need by adding an even higher transfer rates to match these new usages and devices.
DisplayPort 2.0 offers 80Gb of bandwidth, or 2.46x as much as DisplayPort 1.3/1.4. Effective bandwidth is 77.37Gbps, up from 25.92Gbps, an increase of 2.98x. The reason the effective gain is larger than the theoretical standard gain is because of additional efficiency baked into the data encoding standard, which allows DP2.0 to use a higher percentage of its theoretical bandwidth.
DisplayPort (DP) 2.0 is the newest specification released by VESA (Video Electronics Standards Association) in June 2019. This new release comprises of a number of new features and upgrades from the previous DisplayPort 1.4 spec. Let’s get to know the differences between DisplayPort 1.4 vs DisplayPort 2.0, and learn what we can expect with the latest release.
Upgrading to DisplayPort 2.0
While DisplayPort 1.4 has its stake in the market, we will soon be seeing a wider adoption of the latest DisplayPort 2.0 spec from many companies. What can we expect with the newest release?
DisplayPort 2.0 introduces three different bit rates per lane over four lanes, including 10Gbps, 13.5Gbps, and 20Gbps. This means that DP 2.0 can in theory triple its max link bandwidth up to 80 Gbps. However, at this time, VESA is focusing on creating passive cables supporting UBHR 10 (Ultra High Bit Rate), delivering a total of up to 40 Gbps. By increasing the bandwidth to this length, it is stated by VESA, that “DP 2.0 is the first standard to support 8K resolution (7680 x 4320) at 60 Hz refresh rate with full-
While the physical plugs and backward-
All four Thunderbolt connections, therefore, are devoted to transmission, and voila — 80Gbps of signal. This is part of where DisplayPort’s efficiency gain comes from — the move to 128/132-
Cable replacements, however, may be required. DP2.0 introduces three bit rates per lane, at 10Gbps, 13.5Gbps, and 20Gbps. Currently, there are plans to build passive cables for the UHBR 10 standard, which delivers 40Gbps or half the bandwidth that the standard theoretically supports. Any DP cables you see marked 8K ready are UHBR 10 and should conform to the link’s requirements.
For now, however, VESA hasn’t sketched out anything past this. Active cabling may be required to push the kinds of 10K – 16K displays that DP2.0 will theoretically support.
Ordinarily, there’s a substantial lag between when a new standard is available and when GPUsSEEAMAZON_ET_135 See Amazon ET commerce pick it up, but the fact that DisplayPort 2.0 is based on Thunderbolt could speed overall adoption.
DP2.0 packs enough bandwidth to allow for native 8K support without any kind of colour compression or chroma subsampling. Even HDR can be supported with this kind of bandwidth jump. Up to 16K panels can now be connected with DP2.0 and DSC compression, while 10K@60Hz with 24-
