Why test with a red screen?
Red isolates one RGB channel, making certain stuck or dead pixels easier to see than on mixed content.
Red screen
A uniform red screen isolates the red color channel so you can spot dead pixels, stuck subpixels, and panel uniformity issues.

Warum einen Red-Bildschirm nutzen?
Red channel test
Verify the red channel renders evenly from edge to edge on LCD and OLED panels.
Stuck pixel check
Pixels stuck on green or blue may appear as contrasting dots against pure red.
Mood lighting
Red provides dramatic ambient light for photography, streaming, or creative setups.
Red screen for color-channel diagnostics
Cycling red, green, and blue fullscreen colors is a standard quick test for subpixel defects without specialized software.
Perceived red brightness depends on gamma and color temperature — compare results with white and black for context.
