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

How to use these tools
• Full-screen colour test – start the test, then tap/click to cycle through colours. The solid fills make dead (black/white) or stuck (red/green/blue) pixels easy to spot. Tap ✕ to exit.
• Pixel-jog fixer – choose the exact spot of the faulty pixel, then let the flashing square run for a few minutes. Tap anywhere to stop.
• ⚠️ Rapid flashing may affect people with photosensitive epilepsy.

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