PCI-Express isn’t the only technology getting huge upgrades at the moment. After several years, the DisplayPort spec is getting an upgrade, pushing bandwidth speeds higher than before and opening the door for faster refresh rates at higher resolutions.

DisplayPort 2.0 has officially been spec’d out by the Video Electronics Standards Association (VESA), which more than doubles bandwidth compared to DisplayPort 1.4a. With DisplayPort 2.0, you will get 77.4Gbps of bandwidth, making 16K resolution possible at 60Hz while also paving the way for high refresh rate 8K and 4K displays.

Here are the full specs, including single display, dual display and triple display resolutions and refresh rates:

  • Single display: 16K (15360×8460) @ 60Hz and 30bpp 4:4:4 HDR (with DSC), 10K (10240×4320) @ 60Hz and 24bpp 4:4:4 (no compression)
  • Dual display: two 8K (7680×4320) displays @ 120Hz and 30bpp 4:4:4 HDR (with DSC), two 4K (3840×2160) displays @ 144Hz and 24bpp 4:4:4 (no compression)
  • Triple display: three 10K displays @ 60Hz and 30bpp 4:4:4 HDR (with DSC), three 4K displays @ 90Hz and 30bpp 4:4:4 HDR (no compression).

Pushing up to 16K resolutions is quite a feat but for many of our readers, the key thing to keep an eye on is actually the 4K monitor specs. With DisplayPort 2.0, we’ll finally be able to run 4K displays at high refresh rates without reducing colour to 8-bit or using forms of compression. This will be a big step up but of course, we still need GPUs and displays to actually support the new standard first.

KitGuru Says: It has been a long time since DisplayPort last received an upgrade. It will take a while for the industry to actually adopt this new technology but it looks like it will be a significant step up.

While new GPUs and the new 16-core Ryzen 9 processor were the main stars of AMD’s Next Horizon event during E3 this week, there were some other announcements sprinkled in too. In particular, ASUS ROG announced a new monitor, delivering 43-inches of 4K, high refresh rate greatness.

The monitor is currently being previewed, so it could be a while before it hits retail. Aside from the 4K resolution and 144Hz refresh rate, this monitor stand apart from the pack thanks to Display Stream Compression technology, which is allows Ultra HD video streams across a single interface. This technology means that you can run at 4K/144Hz without chroma subsampling, which was an issue found with the very first 4K/144Hz monitors to hit the market. It also means all of this can be done over a single DisplayPort 1.4 connection, rather than needing two.

As you would expect from a monitor being shown at an AMD event, this display does support FreeSync HDR, so you can do away with screen tearing. This new ROG monitor also supports the DisplayHDR 1000 standard, so you get 1000 nits of peak brightness, 10-bit image processing and 90% DCI-P3 gamut coverage.

We don’t know exactly when this monitor will be launching but hopefully we’ll have an update on that front soon.

KitGuru Says: We have a lot of frequent readers who want more large 4K monitors on the market. Asus seems happy to oblige, with this display sitting at 43-inches while retaining all of the gaming features you could want.
