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.

Earlier this week, the repair experts at iFixit opened up the 2018 MacBook Pro
, uncovering Intel's new JHL7540 Thunderbolt 3 controller, introduced earlier this year as part of its "Titan Ridge" family.
While the specifications for the JHL7540
lists compatibility with DisplayPort 1.4
on Intel's product database, it's not as clear-cut as it sounds, as support also relies on graphics, which vary by MacBook Pro model.
MacRumors reached out to Apple for clarification. Here's what we learned:
- The new 15-inch MacBook Pro with Touch Bar models support DisplayPort at High-Bit Rate 3 (HBR3), a signal standard of both DisplayPort 1.3 and DisplayPort 1.4. Apple says the dedicated Radeon Pro graphics can drive up to two 5K displays at 60Hz, each over a single stream.
- The new 13-inch MacBook Pro with Touch Bar models support DisplayPort at High-Bit Rate 2 (HBR2), a signal standard of DisplayPort 1.2. This is a limitation of the Iris Plus Graphics 655 in these models, as Intel's integrated GPUs do not support DisplayPort 1.4.
What that means:
- The new 15-inch MacBook Pro theoretically supports DisplayPort 1.4, which Apple confirmed, but at least for now, it still can't drive an 8K display. It could be possible with VESA's lossless Display Stream Compression standard, perhaps, but it's unclear if this can be enabled down the road.
- For now, then, the new 13-inch and 15-inch models have the same compatibility with external displays as the previous-generation MacBook Pro: up to two 5K displays or up to four 4K displays on the 15-inch model, and up to one 5K display or up to two 4K displays on the 13-inch model.
For comparison, 2016 and 2017 MacBook Pro models are equipped with Intel's JHL6540 Thunderbolt 3 controller
, which supports DisplayPort 1.2.
In related news, Apple has also confirmed that all four Thunderbolt 3 ports on the new 13-inch MacBook Pro with Touch Bar are now full speed
, compared to only the two left-facing ports on the equivalent 2016 and 2017 models.Discuss this article
