Fix the stuck pixels on your screen.
The official Kuycon tool to revive frozen sub-pixels on your monitor. Free, no install, right in your browser.
Rapidly flashing content. Not recommended for photosensitive or epileptic users.
Why the official Kuycon tool
We build screens. So we know exactly how to stimulate a panel to unstick a pixel, safely.
Tuned for our panels
The flashing frequency and pattern are set to effectively stimulate the sub-pixels of Kuycon monitors.
Free and no install
Everything runs in your browser. No download, no data sent, on desktop and mobile alike.
Backed by warranty
If a pixel resists, our support advises you. The warranty covers dead or bright pixels beyond 3, or as soon as one is in the centre of the screen.
How it works
Locate the pixel
Run Test my screen to pinpoint the faulty pixel on solid color backgrounds.
Position the area
Move and resize the flashing window to precisely cover the stuck pixel.
Let it run
Allow 10 to 30 minutes, up to 1 hour. Repeat if needed. The pixel often unsticks on its own.
Stuck pixel, dead pixel or bright pixel?
Kuycon PixelFix is a free tool that runs in your browser, with no install. It flashes red, green and blue very fast over a small area of the screen to restart a frozen sub-pixel, and shows full-screen solid colours to find faulty pixels.
- Stuck pixel: a red, green or blue dot that stays lit. The sub-pixel still gets power but no longer changes state. This is where PixelFix has the best chance of working.
- Bright pixel: a white dot that stays lit, easy to see on a black background. All three sub-pixels are frozen; a PixelFix session is worth a try, with no guarantee.
- Dead pixel: a black dot, easy to see on a white background. The pixel no longer lights up and no software can repair it.
Test your screen in two minutes
First wipe the panel with a dry microfibre cloth, because dust looks like a dead pixel (see our cleaning guide). Then run "Test my screen" and go through the colours in full screen: white reveals dead pixels, black reveals bright pixels, and red, green and blue reveal frozen sub-pixels. Note where each dot is before you start the repair.
What the warranty covers
The Kuycon warranty covers dead and bright pixels beyond 3, or as soon as one is in the central area of the screen. A coloured sub-pixel is not covered, which is exactly where PixelFix is most useful. Everything is explained with diagrams in our article Pixel or sub-pixel: what the Kuycon warranty covers, and the difference between a stuck pixel and a dead pixel in Stuck pixel or dead pixel?
Frequently asked questions
Stuck pixel vs dead pixel, what is the difference?
A stuck pixel stays lit on one color and can often be repaired. A dead pixel stays permanently black, with no power, and usually cannot be fixed by software.
Is it safe for my screen?
Yes, the method is widely used and considered safe. Just avoid running it on a loop for entire days. On OLED panels, keep sessions short.
How long does it take, and does it always work?
From a few minutes to a few hours, and the result is not guaranteed: some stuck pixels recover after the first session, others never do. Start with a 10 to 30 minute session and repeat.
What if it does not work?
Some pixels cannot be fixed. If your Kuycon screen is under warranty, contact our support. Avoid pressing on the panel, which can damage it.
Does it work on OLED, laptop and phone screens?
Yes. It works on any screen shown in a browser: OLED and LCD monitors, laptops, tablets and phones. On OLED, keep sessions short to avoid any risk of image retention.
How do I know if the pixel is fixed?
After a session, run Test my screen again on solid colors. If the dot is gone on every color, the pixel is repaired. If it persists, repeat the repair a few times.
Provided free of charge, with no guarantee of results: fixing a stuck pixel depends on its nature. This tool does not replace the manufacturer's warranty.
