Screen test
Step through color patterns to look for blotches or dead pixels.
Choose a color, inspect the panel, then confirm only what you saw yourself.
Not started
Current color: Red (1/13)
Visual confirmation only — not automatic dead-pixel detection or certification.
Details and limits
How to check
Pick a named color or advance to the next one, then use fullscreen if you need to inspect edges. There is no automatic flashing loop.
Limits
We do not claim automatic dead-pixel or backlight-bleed detection. Outcomes are user-confirmed.
If something feels wrong
If you see blotches, change brightness, reflections, or a screen film, then recheck the same pattern.
FAQ
Fullscreen failed.
Browser policy may block it. Windowed patterns still support visual checks.
Can a screenshot prove no dead pixels?
No. Screenshots do not prove panel health.
