Stuck pixel fix
A small patch that flashes red, green, blue, white and black many times a second. Drag it over a stuck pixel and leave it running. It can free a lazily stuck subpixel; it cannot bring a dead one back.
Photosensitivity warning. The fixer flashes bright colours up to 30 times per second. Rapidly flashing light can trigger seizures in people with photosensitive epilepsy and can cause headaches or nausea. Do not run it if you or anyone who can see the screen is sensitive to flashing light. Stop immediately if you feel unwell.
Why flashing sometimes works
In an LCD, each subpixel is a tiny cell of liquid crystal that twists to let backlight through. If the crystal settles in a stuck orientation, or the cell's transistor is marginal, the subpixel can sit permanently open. Hammering it with rapid on/off transitions gives the crystal many chances to snap back to responding. A dead subpixel with a failed transistor gets no signal at all, so flashing cannot reach it.
A realistic routine
- Find the exact position with the dead pixel test. Stuck pixels show best on black.
- Float the patch over it at 20 changes per second for 10 minutes.
- Check again on black. Repeat up to about an hour in total.
- Still there? Photograph it and contact the retailer or manufacturer while you are inside the return window.
On OLED, a bright dot that won't go away is usually a stuck emitter or driver fault. Flashing is safe to try but less often helps; see the burn-in test for retention issues instead.
Questions people ask
Does a stuck pixel fixer actually work?
Sometimes. Rapidly switching a stuck subpixel between states can free a liquid-crystal cell that is lazily stuck. Results reported by users vary widely, and it cannot revive a dead transistor. It will not harm the panel to try for 10–30 minutes, but the flashing is not safe for people with photosensitive epilepsy, so look away while it runs.
How long should I run it?
Start with 10 minutes, check, then try up to an hour in total. If nothing has changed after that, more time rarely helps.
Is pressing on the pixel a good idea?
Gentle pressure through a soft cloth is a common tip, but pressing on an LCD can create new pressure marks or damage the panel, and it can void a warranty. We do not recommend it on a monitor you may still return.
Can this fix OLED burn-in?
No. Burn-in is uneven wear of the emitters. Use your OLED's built-in pixel refresh or panel maintenance routine instead, and see our burn-in test.
