Stuck pixel fixer

Runs locally

A stuck pixel sometimes recovers after rapid color changes. A dead (always black) pixel cannot be fixed this way.

Photosensitivity warning: this test uses flashing light and fast-changing images, and may play sounds. If you have epilepsy or are sensitive to flashing light, do not use it.

Warning: this tool shows rapidly flashing colors. Do not use it if you have photosensitive epilepsy or are sensitive to flashing light.

How to use

Find the stuck pixel with the monitor test first.

Let it run for 10–20 minutes. Look away from the screen while it flashes.
Check the pixel again. Repeat a few times if needed.

Frequently asked questions

Does it really work?

Sometimes. It helps with pixels stuck on one color, not with dead pixels or pixels that have physical damage.

Can it damage my screen?

No. It only shows changing colors, like a video would.
