Pixel Check - TV Pixels Check and Repair
Apple TV / Utilitaires
Pixel Check is a simple tool that would help you to spot dead/stuck pixels on your TV or monitor screen, and can also repair (unstuck) some of those stuck pixels if they're not already physically damaged.
Simply read and follow the instructions that appear as soon as you launch the App. It's as simple as that!
Please note that sometimes a screen pixel is already physically damaged (completely dead, not just stuck), and in that case, it can not be fixed/repaired by any software means.
