My laptop is flickering a black screen, or holds a black screen in place when high contrast videos and images are visible to large parts of the screen (or at least that's what I've gathered). Although I've found ways of working around this temporarily, it's not very sustainable. For the record, I've tried methods mentioned in many forums but haven't had much success. I would love for some advice please. Thank you so much in advance!
