Quick Answer

With a Ryzen 7 9800X3D processor in the mix, first confirm the dot is truly dead and not just stuck. Dead pixels show no colour at all and cannot be repaired in Windows 11; stuck pixels sometimes recover. If it is dead, lodge a warranty claim, since many monitors near R18,000 carry a pixel guarantee.

Confirm Dead vs Stuck First

Run a full-screen test at 1080p cycling black, white, red, green, and blue for 20 minutes. A dead pixel stays black on every screen; a stuck pixel holds one colour. This step decides whether you attempt revival or move straight to a warranty claim on your a Ryzen 7 9800X3D processor.

Why Software Cannot Fix a Dead Pixel

A dead pixel has lost power to its sub-transistors, so no pixel-cycling tool can light it even after 20 minutes. Tools only help stuck pixels. With a Ryzen 7 9800X3D processor confirmed working elsewhere, accept that a truly dead pixel needs hardware service, not a Windows 11 setting.
