Frequently Asked Questions (FAQ)
What is the difference between a dead pixel and a stuck pixel?
A dead pixel is completely defective and remains permanently dark (usually black) because its sub-pixels receive no power. A stuck pixel is temporarily frozen in a single color state (often red, green, or blue) because of electrical or physical anomalies.
How can I test my monitor or phone for dead pixels?
Launch our Screen Pixel Test and switch to Fullscreen mode. Cycle through solid primary backgrounds (Red, Green, Blue, White, Black). Inspect the display closely; any point that does not match the active solid background color is a dead or stuck pixel.
Can a stuck pixel be fixed online?
Sometimes yes. Stuck pixels can often be forced to reset by rapidly flashing high-contrast RGB patterns over the affected screen area for 10-20 minutes, stimulating the liquid crystals to loosen and resume normal operations.
What is backlight bleeding and how do I inspect it?
Backlight bleeding occurs when the monitor's internal light leaks out around the edges of the bezel panel. You can inspect this by setting the screen test to a solid Black background in a completely dark room, checking if any light spills around the screen frame.
