๐ Dead Pixels
Appear as permanent dark or black specks on light backgrounds. Caused by a dead transistor that receives no power. Cannot be revived via software.
โจ Stuck Pixels
Appear as bright red, green, or blue dots on black backgrounds. They occur when a liquid crystal fails to relax. Often fixable with our rapid RGB flasher!
โ๏ธ Backlight Bleed vs IPS Glow
IPS glow shifts color and brightness when you move your head. Backlight bleed remains fixed at the corners or edges regardless of viewing angle.
