EDP 1.4 Specification PDF: A Comprehensive Guide
The Embedded DisplayPort (eDP) v1.4 specification by VESA optimizes power for internal displays, supporting up to 8.1 Gbps per lane and driving 4K at 120Hz or 8K at 60Hz using compression. Key features include Panel Self Refresh (PSR), Display Stream Compression (DSC), and partial frame updates to enhance mobile battery life.

Display Stream Compression (DSC): eDP 1.4 supports DSC 1.1, which enables visually lossless compression. This allows for higher resolutions (like 4K and 5K) over fewer wires. Higher performance : EDP 1
Q: Can I use an eDP 1.4 panel with an older eDP 1.2 GPU? A: Possibly, but the PDF clearly states that the link will fall back to the lowest common denominator. You will lose HBR3 and PSR2. Always check the "Link Training" section of the spec for fallback modes. and faster data transfer rates
