1.Dead vs Stuck vs Hot Pixels
A dead pixel is a transistor permanently turned off, appearing as a black dot on light backgrounds. A stuck pixel is locked in an open state on one subpixel (red, green, or blue). A hot pixel has all three subpixels permanently on, appearing as a bright white dot on dark backgrounds.
2.The Fullscreen Color Cycling Method
Thoroughly wipe dust from your screen with a dry microfiber cloth before testing. Then launch a fullscreen pixel inspection tool that cycles through solid white, black, red, green, and blue fields, scanning each quadrant systematically.
Frequently Asked Questions
Can stuck pixels be fixed?
Stuck pixels can sometimes be revived by rapidly flashing RGB color cycles or gently applying localized pressure with a microfiber cloth. True dead pixels (damaged transistors) cannot be repaired through software.
