Stuck Pixel Fixer

Cycle colours rapidly over a stuck pixel to try to free it. Works on stuck pixels only.

Flashing images warning

This test displays rapidly changing patterns which may trigger seizures in people with photosensitive epilepsy. It will not start until you choose to begin, and it stops automatically.

How this test works

The pattern cycles red, green, blue, white and black at about fifteen changes a second over the affected area. The idea is simply to drive the stuck subpixel through its full range repeatedly until whatever is holding it at one value releases. Before that, the page tries to save you an hour: a stuck pixel is lit and shows against black, a dead pixel is dark and shows against white, and this routine can only ever help the first. Most pages selling a pixel fixer do not draw that distinction, which is why people run them overnight against faults that were never going to respond. The routine requires a click to start, and the tool carries a photosensitivity warning because rapid full-contrast cycling is precisely the stimulus that provokes photosensitive seizures.

What the results mean

Stuck pixel
Lit, holding one colour, visible against a black field. Still being driven — this is the one that can sometimes be freed.
Dead pixel
Dark on white, receiving no signal. Nothing here helps, and nothing else does either.
Cycle rate
About fifteen colour changes per second — fast enough to work the subpixel, and chosen deliberately rather than as fast as possible.
Time run
Twenty minutes is a short attempt. Some pixels release only after several hours, and repeated sessions work about as well as one long one.

Common problems and fixes

Nothing happened after twenty minutes
That is normal and not the end of it. Try an hour, or leave it overnight. But first confirm the pixel is stuck rather than dead — the white screen test settles that in seconds.
The pixel cleared and then came back
Stuck pixels do re-stick, often in the same place. Running the routine again usually works as well the second time as the first.
I want to press on the screen as well
Only very gently, through a soft cloth, while the pattern runs. Stop immediately if the display distorts under pressure — it is entirely possible to turn one stuck pixel into a patch of dead ones.

Frequently asked questions

Does a pixel fixer actually work?

Sometimes, and only on stuck pixels. There is no reliable success rate to quote — it works often enough to be worth twenty minutes and fails often enough that it should not be promised. On dead pixels it never works, because there is no signal reaching them to cycle.

How long should I run it?

Start with twenty minutes to an hour. If that fails, overnight is the next thing to try. Beyond that the odds fall steeply, and the remaining options are the warranty or the return window.

Is it safe to leave running?

The pattern itself will not damage the display — it is showing ordinary colours. It carries a photosensitivity warning because of the flashing, so do not leave it running where someone might walk into the room unaware.
