The eDP 1.4 standard introduced several revolutionary features that optimized the communication between the graphics processor (GPU) and the internal display panel.
While eDP 1.4 is widely used in millions of devices today, it has been succeeded by . The newer version further refines PSR technology and adds support for Adaptive-Sync, which eliminates screen tearing in gaming—a feature that had its roots in the power-saving protocols of version 1.4. edp 1.4 specification pdf
Instead of the GPU sending 60 full frames every second to the screen, eDP 1.4 can tell the display to "remember" the static image. If only the mouse cursor moves, the GPU only sends the data for those few pixels. This efficiency is why modern Ultrabooks can achieve 12+ hours of video playback. 📑 How to Access the Official PDF The eDP 1
📍 The eDP 1.4 specification is the "gold standard" for high-efficiency mobile displays, balancing extreme high-definition visuals with the aggressive power saving required for modern portable computing. Instead of the GPU sending 60 full frames
Building on earlier versions, PSR2 allows the GPU to enter a low-power state when the screen content is static. It only updates the specific parts of the screen that change, significantly extending battery life.
