The Video Electronics Standards Association (VESA) has announced the latest version of Embedded DisplayPort (eDP) 1.4a standard that will bring 8K resolution to notebooks.

The new VESA eDP 1.4a standard will feature the new Display Stream Compression (DSC) standard v1.1 as well as enhanced segmented panel display architecture. Providing maximum link bandwidth of up to 32.4GB/s, the new eDP 1.4a standard allows support for resolution of up to 7680x4320, also known as 8K.

The new higher HBR3 link rate will provide 8.1GB/s per lane and with Multi-SST Operation (MSO) feature, allows the eDP interface to be divided between two or four independent panel segments, thus providing the aforementioned 8K resolution.

With maximum link bandwidth of 32.4GB/s, the interface will allow output of 8K at 60Hz or 4K at 120Hz with 10-bit color. This will be quite important when it comes to Virtual Reality devices as well as high-performance notebooks.

The rest of the features include an updated Panel Self Refresh (PSR) that was already seen with eDP 1.4, which enables the GPU to update only the portion of the display that has changed since video frame update, thus providing further saving in power.

It will certainly be a while before we see some implementations of the new eDP 1.4a standard, but some manufacturers, like Samsung, are certainly interested in it.
