Chosen Solution

I have these light streaks that appear in some areas and disappear in the midst of the colors I never erased the screen and I don’t know what to do And the problem frustrates me in some games when it appears

I want to point out that what I noticed is that these relics were in the form of menu icons for a game I played a lot ( Although it is not very clear, I made sure that it takes the same place and shape as the icons in this game ).   (It is noticeable that this defect does not appear in the five colors R-G-B & Black & Withe = with app UDPixel)

@kinglords It’s almost like screen burn in but you’d think that it would be noticeable when testing solid colours as well. Maybe try a different resolution (frequency refresh rate <144Hz) and check. If the monitor is no longer covered by the warranty you may have to open it up and check for anything obvious on the control board, although I think that it’s more likely to be the LED pixel drivers in the panel, which are internal to the panel Here’s the service manual that may help.
