Fix stuck pixels with rapid colour flashing
A stuck subpixel can sometimes be freed by rapidly cycling colours for 10–30 minutes. Warning: this flashes quickly.
How the fixer works
Rapid changes exercise the liquid crystal of the stuck subpixel and can release it.
Gentle pressure method
Some people press gently with a soft cloth over the pixel while the screen is off; risky, so be careful or avoid.
Photosensitive epilepsy warning
Flashing images can trigger seizures.
