Technology has changed dramatically and the display screen has 4K resolution, then 6K / 8K has gradually appeared more than the market, the connection standard supporting it as well as DisplayPort certainly need to upgrade. That came true, three years after the latest standard launch, DisplayPort 1.4a, the latest connectivity standard DisplayPort 2.0 was introduced, providing nearly three times the bandwidth of its predecessor.
Specifically, on June 27, the Video Electronics Standards Association (VESA) officially announced DisplayPort 2.0 connectivity standard, as a perfect step for the arrival of the first 16K monitors. First in the world only in the next few years. DisplayPort is an image export standard used in Thunderbolt 3 ports, on older Apple computers, and also with many removable monitors that support DisplayPort ports. DisplayPort is currently in version 1.4a (released in 2016), and the latest DisplayPort 2.0 has been upgraded to triple the bandwidth: from 25.92Gbps to 77.4Gbps.
This is clearly a good news for users who use high resolution screens. DisplayPort 2.0 is the first standard to support 8K resolution at 60 Hz image refresh rate with full color 4: 4: 4 resolution, along with 30 bits per pixel (bpp) to support HDR10.
And thanks to wider bandwidth, DisplayPort 2.0 can support exporting images up to 16K (15,360 x 8,460) at 60Hz. But because this resolution has not yet appeared, it is more realistic, you can output to 3 4K screens at the same time with 90Hz scan frequency or export to 2 8K monitors at 120Hz.
We can take examples to make the most of this bandwidth level like:
- For a screen
– A 16K screen (15360 × 8460) @ 60Hz and 30 bpp 4: 4: 4 HDR (with DSC)
– A 10K screen (10240 × 4320) @ 60Hz and 24 bpp 4: 4: 4 (uncompressed)
- For two screens
– Two 8K (7680 × 4320) monitors @ 120Hz and 30 bpp 4: 4: 4 HDR (with DSC)
– Two 4K screens (3840 × 2160) @ 144Hz and 24 bpp 4: 4: 4 (uncompressed)
- For three screens
– Three 10K screens (10240 × 4320) @ 60Hz and 30 bpp 4: 4: 4 HDR (with DSC)
– Three 4K screens (3840 × 2160) @ 90Hz and 30 bpp 4: 4: 4 HDR (uncompressed)
It all comes through a separate DisplayPort connector. If connecting via USB-C as enabled by DisplayPort Alt mode, the parameters are as follows:
- Three 4K screens (3840 × 2160) displays @ 144Hz and 30 bpp 4: 4: 4 HDR (with DSC)
- Two 4K x 4K monitors (4096 × 4096) displays (for AR / VR headsets) @ 120Hz and 30 bpp 4: 4: 4 HDR (with DSC)
- Three QHD screens (2560 × 1440) @ 120Hz and 24 bpp 4: 4: 4 (uncompressed)
- An 8K (7680 × 4320) display @ 30Hz and 30 bpp 4: 4: 4 HDR (uncompressed)
With DislayPort 2.0, VR glasses will also see smoother, sharper images as it can now handle two 4K x 4K monitors with a refresh rate of 144Hz, significantly reducing dizziness and lagging. when wearing virtual reality glasses. Previously, the VR glasses used only 2K resolution, so the image was not as clear, and if the resolution increased, it had to reduce the scanning frequency, so the motion picture was not smooth.
DisplayPort 2.0 will be compatible with its previous versions, including key features, such as Forward Error Correction (FEC), and HDR metadata transport, along with support for USB Type connection cables. -C and Thunderbolt 3 for data transfer.
VESA said the first technological devices to incorporate DisplayPort 2.0 will be available by the end of 2020.
