Like the title says, should I replace it? Store's policy says items can be replaced with the same brand which is fine with me. I have an AOC E2250swdn. The dead pixel is found at the lower left corner of the screen, right beside the windows start menu. It's visible in lighter colors and cannot be seen in black and darker colors. I've tried online video fixes and rubbing it with a damp cloth.. Should I be worried? I can live with 1 dead pixel but I'm afraid maybe more dead pixels will appear starting with this one.
