I upgraded my laptop display but there's a bug where if the picture on display is too high a percentage of one shade of red or blue it will flicker and black screen. So I can watch a pixel test video in regular screen but in full screen, the red and blue slides will just black screen my display. It seems the threshold is about 2/3 of the display. The more homogeneous the colors are on screen the more likely I will get flickering, so I even see occasional flickering in YouTube videos but very very rarely. Stock screen was 1366x768, new is 1080p but the eDP cable pinouts are the same, voltages pretty much the same in datasheets but I need to go back and check.

Any idea what is going on?

Edit: my current solution here, but still don't understand fully what is going on
