Full-screen colour test ⓘ

Found a dead pixel?
Run the pixel-jog fixer ⓘ

Full-screen colour slides may reveal dead pixels; a flashing pixel-jog square can help to revive stuck ones.

Full-screen test:
• Page enters full-screen.
• Tap to cycle colours.
• Tap the ✕ button to exit.

Pixel-jog fixer:
• Cursor becomes a cross-hair—tap the faulty pixel.
• A 250 px square flashes random colours (max 10 min).
• Tap anywhere on the page to stop.

⚠️ Rapid flashes can trigger photosensitive epilepsy.
