He drafted an email to the firmware lead. "Subject: Re: Black Screen Issue - Root Cause Identified. Reference: VESA EDP 1.4 Spec, Page 184, Section 5.2.3. We are violating T3 timing. Change the backlight delay to 100ms. The PDF doesn't lie."
To prevent video playback stuttering, eDP 1.4 allows the panel to seamlessly adjust its refresh rate to match the frame rate of video content. For example, when playing a 24 fps movie, the link can dynamically drop the display refresh rate from 60Hz down to 48Hz or 24Hz, eliminating frame-skipping artifacts while dropping system power consumption. eDP 1.4 Pinout and Electrical Changes edp 1.4 specification pdf

The displays of the future rely on the standards of today. eDP 1.4 represents a mature, powerful, and well-documented bridge between silicon and screen. He drafted an email to the firmware lead
The eDP 1.4 specification is an industry-standard interface designed to transport video and audio data from a system-on-a-chip (SoC) or GPU to a flat panel display (typically LCD or OLED) in mobile and portable devices. It builds upon the DisplayPort 1.2 architecture but adds critical features aimed at reducing power consumption and supporting higher resolution panels in thin form factors. We are violating T3 timing
“The source must allow a minimum of 100ms for the panel internal logic to stabilize before asserting the backlight enable signal.”
Enables 4K (3840x2160) and QHD+ resolutions at 60Hz or higher while preserving battery life during office productivity tasks.
