A new level of connection DisplayPort 2.0 it is already a reality, and in fact i first devices which includes (although adopted in June 2019). This new connector is similar to the previous one (DisplayPort 1.4) but includes a lot of improvements, especially which increases the compatibility of the new generation display and larger resolutions.
When it comes to video streaming, HDMI is the first thing that comes to mind for almost everyone. Version 2.1 of this standard looks forward and supports refinement 8K FPS 60, and with DisplayPort 2.0 it was wanted to do the same thing but with a much broader future. If in the past some high-resolution and / or analytical solutions required several cables simultaneously to support bandwidth, this standard seeks to combine everything with one cable.
DisplayPort 2.0, what features?
The main difference of this level is with the previous one and with HDMI lying heavily on its wide bandwidth; high bandwidth allows multiple data to pass through it simultaneously, so that a large amount of data can be transferred simultaneously. The result is that this supports higher resolutions and higher levels of recovery.
Therefore, the DisplayPort 2.0 cables support up to 77.4 Gbps bandwidth, almost three times that of DP 1.4 and about twice as much as HDMI 2.1 (48 Gbps), which allows it to be used on monitors with a resolution of up to 16K, which is sixteen times longer than the 4K monitors which by mid-2020 have not yet reached the standard. Of course, in addition to high resolution, this high bandwidth allows for high levels of refreshment and traditional HDR. As we said earlier, the idea is to look to the future and I don’t have to update the standard again for many years.
For the same reason VESA seems to want to upgrade the Thunderbolt 3 connector, which is also based on USB 4.0 standard. Finally, with all levels integrated into a single connector, it will make their performance much cheaper, although it may confuse users because we will be talking about DisplayPort, Thunderbolt and USB using the same type of connection.
What decisions can we apply with DP 2.0?
To achieve this broad bandwidth, VESA relies on the physical distribution of Thunderbolt 3 connectors. They have thus obtained a standard that can support, for example, 8K resolution at 60 Hz at 4: 4: 4 color and traditional HDR10 support with no chroma subsampling; for this reason, we can use, for example, the following options:
- 16K resolution (15360 x 8460 pixels) with refresh rate of 60 Hz, 10 bits and HDR (with DSC).
- 10K resolution (10240 x 4320 pixels) at 60 Hz with 8 pieces (excluding DSC).
By two monitors:
- 8K resolution (7680 x 4320 pixels) at 120 Hz, 10-bit and HDR (with DSC).
- 4K resolution (3840 x 2160 pixels) at 144 Hz and 8 bits (excluding DSC).
- 10K resolution (10240 x 4320 pixels) at 60 Hz with 10 pieces and HDR.
- 4K resolution (3840 x 2160 pixels) at 90 Hz with 10 pieces and HDR.
