How to use
A dead pixel stays black on any color. A stuck pixel stays one fixed color. A hot pixel is always white. Cycle through all colors and inspect your screen carefully in a darkened room.

Tips for accurate testing
🌑 Dim the room
Test in a darkened environment to make subtle pixel defects easier to spot.
👁️ Inspect closely
Move close to the screen and scan slowly, especially edges and corners.
🔄 Test all colors
A stuck pixel may only be visible on certain colors — test all 8 screens.
🛠️ Stuck pixel fix
Stuck pixels (not dead) can sometimes be fixed by gently massaging the area or using pixel-fixing software.
