Display for MacBook Pro model
The screen on your MacBook Pro 2020 has developed an unusual tint in one area while you were using videos. It seems to be a hardware issue rather than a software problem. You don’t need to replace the entire display unless the tint persists and affects your viewing experience. Consider checking for loose connections or dust buildup, but if the problem continues, it’s best to consult a professional technician.
It could be a minor problem since the ribbon cable works, but it appears a selection was made. Have you attempted to reset the PRAM?
Reset of the PRAM failed. The screen works perfectly, except for the high brightness area.
Have you ever disassembled these items before? It’s pretty straightforward with the right tools. Unless you used one of those three-year Apple service plans, I’d suggest opening the MacBook, giving it a light cleaning, and gently reinserting the ribbon cable. I once dealt with an older PowerBook where a similar problem occurred. It wasn’t as severe, but swapping out the cable and putting it back fixed the color distortion on the left side of the screen. The display itself was fine, though the lines looked completely different. I’m not sure if the cable was the fix or just a simple clean. There was an app that could quickly switch solid colors, which sometimes helped. You might also try checking desktop pictures and manually picking solid colors to see if it makes a difference. It seems the screen is working, but there might be an issue with the signal passing through the cable. It feels like the same feeling as when you take a screenshot and change colors rapidly. The program I used for fast solid color changes is no longer available, but maybe someone can help identify it.
If the panel isn't working properly, consider replacing it when possible.
