Quick Answer
A stuck pixel (frozen on one colour) is usually fixable for free with JScreenFix or UDPixel in 15-30 minutes - it is different from a dead pixel, which stays black and needs a warranty claim. Run the software tool first; if that fails, a gentle pressure method sometimes works. Most monitors sold locally carry a 2-3 year warranty, so keep your invoice if the panel is genuinely faulty.
Stuck vs dead: confirm first
Cycle a full-screen image through black, white, red, green, and blue at your panel's native refresh rate, whether 60Hz or 144Hz. A stuck pixel shows the wrong single colour on some screens; a dead pixel stays black on all of them. Stuck pixels are caused by a sub-pixel frozen in one state and respond well to rapid colour flashing. Dead pixels have lost power entirely and software cannot revive them.
The free software fix
JScreenFix runs in any browser and flashes a noisy block of colour over the stuck area at high speed - drag it onto the affected spot and leave it for 15-30 minutes. UDPixel does the same on Windows. This is genuinely free and resolves the majority of stuck pixels without touching the panel or risking your warranty.
Pressure method and warranty
If software fails, power off, lay a soft microfibre cloth over the pixel, apply light pressure with a rounded blunt tool, and power on as you release. Do not press hard. If the pixel is dead, lodge a warranty claim: monitors at Evetech carry 2-3 year cover, and LG, Samsung, and MSI each publish a dead-sub-pixel threshold before replacement.
FAQ
How do I fix a stuck pixel for free?
Run JScreenFix in your browser or UDPixel on Windows and let the flashing block sit over the pixel for 15-30 minutes. This clears most stuck pixels at no cost.
What is the difference between a stuck and dead pixel?
A stuck pixel is frozen on one colour and is often fixable; a dead pixel stays permanently black and usually needs replacement. The colour-cycle test tells them apart in seconds.
Will a stuck pixel get worse over time?
A stuck pixel can sometimes clear on its own or with a fix tool, but it will not spread. A growing patch of black pixels, however, points to a panel fault worth a warranty claim.
Try JScreenFix free for 20 minutes first - if the stuck pixel persists or is dead, lodge a warranty claim through Evetech with your invoice and a photo of the defect.
