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.

MSO allows a single display configuration to split its interface across multiple independent stream transports (SST). In eDP 1.4, MSO enables a high-resolution display panel to be segmented into two or four separate operational regions.

For a detailed analysis of how this standard is tested, documentation from vendors like Teledyne LeCroy regarding eDP 1.4 test solutions can provide practical insights into its implementation. Conclusion For a detailed technical overview, see the eDP 1

While searching for the "edp 1.4 specification pdf," you may see version 1.4a or 1.4b. These are minor revisions. The base 1.4 spec introduced the major features. 1.4a clarified PSR2 operation and fixed typographical errors in the timing tables. 1.4b added optional support for 4K at 240Hz by tightening the jitter requirements. For most engineering purposes, , but all are collectively referred to as "eDP 1.4."

Achieves a raw data rate of 21.6 Gbps.
