3) Exit: ESC or tap/click screen

Tint: pink/green corners or uneven colour

Brightness: uniformity across the panel

Dust: specks show clearly on white

Eyes: white at max brightness can be harsh.

Heat: phones can warm up — take breaks.

OLED: long bright static screens aren’t ideal.

Is it truly white? yes — the overlay is #fff.

Looks warm/cool? that’s your colour temperature.

Why banding? try 766 gradient test.

Dead pixels? use 763–765 colours too.

Fullscreen blocked? browser policy.

Try again after a direct tap, or use START only.

Exit: ESC (desktop) or tap (mobile).

For checks: mid brightness often reveals issues better.

For photos: raise brightness for a cleaner fill light.

White screens are great for spotting tint, uniformity issues, and dirt.

They also work as a quick fill light for small product photos.

Exit instantly with ESC (or tap), and avoid long max-brightness sessions.
