Purple screen FAQ
- What is a purple screen used for?
- Ambience, mostly — purple is the classic gamer-room and party glow, and a spare monitor showing this page does the job of an LED strip. Technically it's also a red-plus-blue check: purple drives those two subpixel channels with green off, so a dot that looks wrong here but fine on green narrows the fault down.
- Is a purple screen the same as a blacklight?
- No. A blacklight emits ultraviolet — light beyond what displays produce or eyes see — which is what makes posters and security ink fluoresce. A purple screen just mixes visible red and blue; it won't make anything glow, cure UV resin, or reveal stains. Panels deliberately emit almost nothing in the UV range.
- Why does purple look blue or magenta on my screen?
- Purple balances two primaries, so panel differences tip it easily: a display with a dominant blue primary drags it toward violet-blue, while a strong red or a warm picture mode pushes it toward magenta. If two of your devices disagree, both are 'correct' by their own calibration — purple just makes the disagreement visible.
