I recently bought a used dell u2212hm on eBay. The seller said it didn't have any stuck or dead pixels, but when I powered it on I saw a black dot on the screen. I have owned multiple devices with stuck and dead pixels before, and the defect on the screen didn't look like one so i was thinking that it might be a scratch or something. Is it a stuck/dead pixel or a scratch and is there anyway I can fix it?
Thats a pressure spot not dead pixel.
Someone used kung fu finger jab directly into the screen.
This damage is permanent. Its not manufacturer defect. And its not covered as bad pixels under warranty.
