Engineered for Every Display Task
From professional video meetings to monitor maintenance, photography, and restful sleep.
Zoom & Webcam Soft Light
Turn your second monitor or laptop screen into a soft, diffused ring light. Use our Kelvin temperature slider to match your room lighting from 2700K warm candle to 6500K crisp daylight.
Monitor Cleaning & Inspection
A high-contrast white screen immediately exposes specks of dust, fingerprints, water spots, and micro-scratches on glass, IPS, and OLED displays.
Dead Pixel & Subpixel Test
Cycle through pure Red, Green, Blue, Black, and White test patterns to identify dead (dark) or stuck (single color) subpixels across your monitor panel.
OLED Black & Backlight Bleed
Test IPS corner glow, clouding, and backlight uniformity. On OLED panels, `#000000` turns individual pixels completely off for zero power draw and infinite contrast.
Digital Lightbox for Tracing
Place translucent paper or film directly over your tablet or laptop screen. Lock brightness to 100% and enable Wake Lock to trace sketches, calligraphy, and architectural blueprints.
Deep Focus & Sleep Timer
Eliminate distracting glowing screens in dark bedrooms. Combine OLED pure black with offline white or brown noise synthesis and automated sleep countdown timers.
