Drive 4K and higher resolutions using just 2 lanes instead of 4. 4. Advanced Link Power Management (ALPM)
Released as an advancement over eDP 1.3, the 1.4 revision introduces smarter power management and higher data rates. It relies on the VESA DisplayPort 1.3 physical layer standard but tailors its features specifically for internal, embedded displays where power conservation and space reduction are paramount. 1.

: Driving higher resolutions and color depths over fewer physical wires.
Facilitates adaptive sync protocols to synchronize panel refresh rates directly with varying game frame rates. Drive 4K and higher resolutions using just 2
The pins are architecturally divided into three functional categories:
At its core, eDP 1.4 adapts the external DisplayPort 1.2a and 1.3 physical layer capabilities for internal use. It enables device manufacturers to transmit massive amounts of video data across minimal physical wires, reducing electromagnetic interference (EMI) and allowing for thinner device chassis designs. 2.

If you are a display designer, embedded systems engineer, or a developer, keeping up with the eDP 1.4 specification is crucial for creating next-generation devices.
