About ScreenGlowWhite

ScreenGlowWhite is a small set of free, browser-based tools built around one idea: sometimes you just need your screen to display a plain colour or a simple test pattern, without installing anything.

What's here

A full-screen colour tool with curated presets and a custom picker, a dead pixel test, and a brightness/calibration check — each one built to be fast to load and simple to use on desktop or mobile.

Who's behind it

Edmund S Ahiakpa. Built and maintained independently.
