while pushing higher resolutions like 4K and 8K. Before this version, internal display interfaces often consumed significant power just to keep a static image on the screen. Key innovations in the eDP 1.4 standard include: Panel Self Refresh (PSR):
DSC is a "visually lossless" compression algorithm. It allows a display to transmit data that would normally exceed the physical bandwidth of the cable. edp 1.4 specification pdf
You might assume that with eDP 1.5 (released around 2019) now available, version 1.4 is obsolete. That is far from the truth. while pushing higher resolutions like 4K and 8K
For a standard 4-lane eDP connection, this effectively increased the maximum available bandwidth from 21.6 Gbps to 32.4 Gbps. This bandwidth boost was essential for driving 4K (3840 x 2160) panels at 60Hz and beyond without the need for chroma subsampling (compressing color data). It allows a display to transmit data that
Here are the four pillars of the eDP 1.4 specification that changed the industry.
