Dead and Stuck Pixel Test
Inspect black, white, red, green and blue full-screen fields for pixel defects.
A fixed dark or bright point is visible on the panel.
This focused entry uses the shared Display protocol. The measurement logic and Evidence version remain identical to the complete lab.
Remove the easiest false alarms first.
01
Set browser zoom to 100%, keep the tab visible and close animated or high-load windows.
02
Confirm the operating-system refresh, HDR and scaling settings before comparing results.
03
Change only one display setting per run and keep room light stable for visual references.
Run one repeatable protocol.
- 01
Clean the screen and enter fullscreen.
- 02
Inspect all five solid fields at normal viewing distance.
- 03
Recheck the suspect point against another image source.
Evidence the result should expose.

Separate observed, review and inconclusive.
Repeat long-frame or visual artifacts after checking zoom, power mode, duplicated displays and the selected monitor mode.
A browser cannot certify panel response time, PWM, peak brightness, gamut volume or calibrated gamma without external instruments.
Start with the likely path, then retest.
