VESA Publishes eDP (Embedded Display Port) 1.4a Specification - Resolution upto 8K Supported

VESA has revealed the eDP 1.4a standard and the new iteration supports VESA Display Stream Compression, enables new segmented panel display architecture and increases panel resolution support to up to 8K (along with some make new features). eDP is currently beingness utilized in both Nvidia GSync Mobility and AMD FreeSync so this new iteration is of interest to both camps. You lot tin find the full press release published past VESA over at their homepage.

New eDP 1.4a VESA standard ushers in new features for laptops, notebooks and mobile devices

The new VESA standard for desktops (one.iii) was recently revealed and it twas time for the embedded standard (laptops, notebooks etc) to receive an update as well. Some of the primary features of DP ane.3 are also role of eDP 1.4a (such as the 8.1 Gbps per lane and the new HBR3 link ) non to mention DSC v1.1. I think I volition let VESA summarize the new feature for me:

An entirely new feature in eDP v1.4a is "Multi-SST Functioning," or MSO, which supports a new blazon of display architecture that VESA calls "Segmented Panel Brandish." Segmented Panel Display is designed to enable thinner, lighter and lower-cost panels that use less power. In operation, MSO allows the 4 loftier-speed eDP data lanes inside the eDP interface to exist divided up between either ii or four independent panel segments. For lower resolutions, two lanes can exist used to support two panel segments. This panel segmentation enables a higher level of integration on high-resolution displays; each segment can incorporate a separate timing controller with integrated source drivers.

Interestingly the AUX Channel and HPD seem to be favoring a same line return and a serial arroyo with panel division. This leads me to the next feature, something pretty of import for future adaptive sync technologies: The inclusion of the fractional update adequacy for Panel Self Refresh (PSR) that was introduced in eDP 1.four. Fractional update enables the organisation video processor, or GPU, to update only the portion of the brandish that has changed since the video frame update, farther saving organization power.

All in all, the mobility display applied science niche is shaping up very nicely and nosotros already know that Nvidia Mobility will be coming in a few months. To my knowledge AMD Freesync has withal to be commercial in the mobility side of things only I am sure these ii techs will follow each other to the scene soon plenty. While these 2 volition be based on an older variant of eDP, eDP 1.4a is slated to enter mainstream markets past 2022, so its a total yr abroad at least.
