Dead Pixel questions, fixes and result guides.
Practical answers for common dead pixel problems, confusing results and setup questions — with a direct path back to the live test.
How do I check a monitor for dead pixels?
Use solid black, white, red, green and blue fullscreen patterns and inspect the panel from a normal viewing distance. A pixel that stays consistently dark or stuck on one color across patterns deserves closer inspection.
Can a stuck pixel come back to normal?
Some stuck subpixels can be intermittent, but there is no guaranteed browser-based repair. Avoid aggressive pressure or flashing methods that could damage the panel or create discomfort.
Why do dead pixels show better on certain colors?
Different solid patterns activate red, green and blue subpixels in different combinations. A defect can therefore be much easier to see on one background than another.
What is the difference between a dead pixel and a stuck pixel?
A dead pixel often stays dark, while a stuck subpixel can remain red, green, blue or another fixed color. Several solid patterns help distinguish them.
Can this website repair a dead pixel?
No. The tool is for visual inspection only and cannot repair physical panel damage.
How accurate is this dead pixel tool?
A web page can help you inspect pixels, but it cannot repair physical display damage.
What should I do if the dead pixel result looks wrong?
Clean the screen gently, test multiple colors and confirm the mark stays in the exact same panel location. This tool can reveal a symptom but cannot repair damaged display hardware.
