New specification for embedded DisplayPort 1.4a supports 8k resolution




VESA has published version 1.4a of embedded displayport’ standard. The new standard will include higher throughput for video signals possible. These higher speeds should allow 8k associate professor screens on devices like laptops and tablets.

The embedded display port 1.4a’ specification is an extension of the ‘1.4-embedded displayport’ standard, which was published in February 2013. If the specification is based on the “normal” 1.4-display port standard. This gives the 1.4a standard a link rate of 8,1Gbit / s per lane. This higher throughput displays with 8k resolutions need to be controlled, while greater color depths are possible.

Embedded DisplayPort 1.4a also introduces a new feature that has been baptized by VESA multi-SST operation ‘. Through this mechanism, energy-efficient, thin and light screens must be efficiently managed. The multi-SST technology is according to VESA adduced by Samsung to send as cheaper and more economical LCD panels.

VESA has also improved the panel self refresh mechanism. In the 1.4a specification, the GPU can be controlled so that it only needs to update the portion of the screen that has actually changed, after processing a frame. This mechanism should also reduce energy use such as laptops or tablets.

VESA, the first devices that use the embedded DisplayPort 1.4a’ specification in the course of next year on the market.
