Sometimes you just need the screen white and bright: as a fill light, a tracing lightbox, a quick photo booth backdrop, or to check a display for dead pixels and backlight bleed.
CineGlow's Pure white preset is exactly that — true RGB 255,255,255 at fullscreen with the interface completely hidden. And when pure white looks too cold on camera (it usually does), the Kelvin slider is right there: 5600K reads as clean daylight, 4000K as neutral, 3200K as warm tungsten.
Screen checking tip: at fullscreen white, dead pixels show as dark specks; drag brightness down to spot backlight bleed at the edges. Flip to the solid color presets to catch stuck subpixels.
Open the white screen →Beyond lighting, a full-white screen is a practical tool: it's a tracing lightbox when you place thin paper against a tablet, a dead-pixel test (dark specks are dead subpixels), a backlight-bleed test at low brightness in a dark room, and a quick backdrop for photographing small objects. It's also useful for testing a screen you're considering buying secondhand — a full white field reveals uniformity problems that normal desktop use hides.
