VESA today announced the release of DisplayPort 2.0, the first major update to the standard since DisplayPort 1.4 in March 2016.


DisplayPort 2.0 has a max effective bandwidth of 77.4 Gbps, nearly triple that of DisplayPort 1.4, enabling support for displays with up to 16K resolution, higher refresh rates, HDR support at higher resolutions, improved support for multiple display configurations, and more.

The increased bandwidth is the result of VESA leveraging Thunderbolt 3's physical layer. DisplayPort 2.0 is the first standard to support 8K resolution at a 60Hz refresh rate with full-color 4:4:4 resolution and HDR-10 support.


DisplayPort 2.0 configuration examples via DisplayPort, USB-C, or Thunderbolt 3 ports, which will all support the new specification:
Single display resolutions
- One 16K (15360x8460) display @60Hz and 30 bpp 4:4:4 HDR (with DSC)
- One 10K (10240x4320) display @60Hz and 24 bpp 4:4:4 (no compression)

Dual display resolutions
- Two 8K (7680x4320) displays @120Hz and 30 bpp 4:4:4 HDR (with DSC)
- Two 4K (3840x2160) displays @144Hz and 24 bpp 4:4:4 (no compression)

Triple display resolutions
- Three 10K (10240x4320) displays @60Hz and 30 bpp 4:4:4 HDR (with DSC)
- Three 4K (3840x2160) displays @90Hz and 30 bpp 4:4:4 HDR (no compression)
DisplayPort 2.0 also supports VESA's new Panel Replay capability for improved power efficiency when connecting to high-resolution displays.

VESA has made the DisplayPort 2.0 specification available to manufacturers and expects the first products incorporating the standard to appear on the market by late 2020. DisplayPort 2.0 is backward compatible with previous versions of the standard and incorporates all of the key features of DisplayPort 1.4a.

DisplayPort 2.0 will certainly be beneficial to Apple's high-resolution products like the upcoming Pro Display XDR, and it will likely be supported on future Macs, but it is unclear when the company will adopt the standard.

Awesome, I suppose? I'm guessing most laptops, Mac or PC, won't really benefit without a serious update to graphics chip, which itself brings about a new set of thermal challenges. On the desktop side, I suppose that likely just leaves the Mac Pro, and PC towers seriously capable of driving so many pixels?

Not until a future Thunderbolt standard incorporates DP 2.0 and 80 Gbps bandwidth - or Apple backtracks and adds DP connectors to their Macs and displays. Thunderbolt only got DP 1.4 support last year.

Wow, just wow. But how much will a 16k monitor cost, when one becomes available? Definitely for pro video processors, at least for a few years.
Many thousands. Then some Chinese company will ramp up production a year or two later and butcher prices down to a few hundred dollars for entry level. Like what happened with 4K TVs and monitors. They were several thousand then BAM, several hundred.

While others see a specification for what appears to be absurd resolutions and refresh rates (by today's standards), I see a specification with some room to grow all while allowing things today that were not otherwise possible. I like it.

I think that bandwidth is sufficient to be able to run an eGPU on an internal monitor at reasonable 1440p resolutions. Could be a game changer for iMacs and eGPUs.

Serious, MacRumors editors...the most important, well, relevant part of the Press Release was left out of this article.

From the Press Release:

When using only two lanes on the USB-C connector via DP Alt Mode to allow for simultaneous SuperSpeed USB data and video, DP 2.0 can enable such configurations as:

• Three 4K (3840×2160) displays @144Hz and 30 bpp 4:4:4 HDR (with DSC)
• Two 4Kx4K (4096×4096) displays (for AR/VR headsets) @120Hz and 30 bpp 4:4:4 HDR (with DSC)
• Three QHD (2560×1440) @120Hz and 24 bpp 4:4:4 (no compression)
• One 8K (7680×4320) display @30Hz and 30 bpp 4:4:4 HDR (no compression)​

The above specs are much more relevant to most of the computing public in the near-term. The market penetration of 4K and subsequently 4K gaming and AR/VR applications is something we should all be paying attention to for the foreseeable future. Whoever in the Marketing Department at VESA came up with 10K as a bullet point gets props for creating it out of whole cloth, unless they know something we don’t know. Sure, a Medical Imaging monitor may hit 10K shortly, but consumers are still wrapping their head around 4K, much less 8K and higher. The 16K resolution is just absurd for almost every consumer front facing application. I love future proofing and high end specs as much as the next person, but driving a 4K display @144Hz or 4K VR@120Hz with full color and HDR is incredibly important in the immediate future. Hell, Digital Cinema Projectors are only pushing 4096x2160.

Of course, this sort of support is only going to be relevant to us (Mac users) when Intel revs the next Thunderbolt 3 controller to support DP 2.0. Alpine Ridge (2016-2017 MBP, 2017 iMac and iMac Pro) has DP 1.2 and Titan Ridge (2018-2019 MBP, 2018 Mac mini, 2019 iMac and 2019 Mac Pro) have DP 1.4, but DP 1.4 support is limited to Coffee Lake and above on is limited to the eDP connector for an LCD panel.

The most important thing is how the morass of USB-C 3.2, 3.2+2, USB 4.0 will interoperate (or not) with Thunderbolt 3 and when and if Thunderbolt 4 becomes a real thing or not and move users to DisplayPort 2.0 (or not). Certainly this connectivity will be integrated into PCIe-based AIB GPUs first and motherboards and controllers, CPUs second. This is where the rubber meets the road in terms of PCIe 4.0+ being relevant for most of us, aside from the possibilities of PCIe 4.0-based SSD controllers and NAND pushing into 5–7GBps Read/Write speeds on an m.2 NVMe stick.

The future is always just around the corner.

I would upvote this more if I could.

16K? Seriously? Unless your screen is as big as a house, I don't see how people benefit. Your eyes can only detect so much.
It's not about the big picture. It's about the small details in that picture. Instead of trying to discern certain aspects of the picture, you can now see them with the higher resolution.

Think of magnification of small details when retouching a picture or editing video.

Agreed, the average Joe will quite possibly never notice the difference to 16k. I can only see 16k being something good in a movie theater, where detail is expanded.

So with this we can finally make use of the full potential of a eGPU rather than the bottleneck we have today?
Not for nothing but I believe a big part of that bottleneck is planned to be improved with a fall update in the shipping version of Catalina. Someone posted a screenshot of it somewhere (maybe on this site) but I can't find it.

Thanks!

My view is that 4K is relevant today, especially getting HDR better visibility and market penetration. Maybe 4K gets skipped and we go right to 8K (I don’t think so), but AMD and NVIDIA are still going to have a hell of a time making a reasonably priced GPU push 8K@144Hz.

To me, this means more for VR, although I am not really sold on VR for myself...but it is still important. I guess I wish the author had incorporated the additional portion of the press release into the article.

Wherever my feet take me…
I wonder what Thunderbolt 4 will bring? With the final PCIe 5 specification here, and 6 sometime in 2021 (according to Wikipedia). Plus, with USB-4 taking a lot from Thunderbolt 3, and now this.

In some ways, I wonder if/when we'll go from 2D displays to 3D? Not sure how that would work, though.
