GlowScreen

What is GlowScreen?

GlowScreen is a free, browser-based utility that turns your screen into a pure, full-screen color display. Whether you need a white screen for cleaning, a black screen for contrast testing, or colored screens for photography lighting and video production, GlowScreen delivers instantly—no installs, no tracking, no distractions.

Simply pick a color, hit fullscreen, and your display becomes a calibrated light source or test pattern.

3. Set resolution (optional) — Choose a preset (480p–8K) or enter custom dimensions.
