How to Spot Dead Pixels
This tool fills your entire screen with a single color. This makes it easy to spot any pixels that are not working correctly.
- On White Screen: Look for black dots (Dead Pixels).
- On Black Screen: Look for bright colored dots (Stuck Pixels) or uneven lighting (Backlight Bleed).
- On Red/Green/Blue Screens: Look for pixels that are a different color than the rest.
