Confirm the pixel is dead, stuck, or a dust speck by displaying solid black, white, red, green, and blue screens
Restart the laptop
Gently tap the area around the pixel with a soft microfiber cloth
Use a pixel-fixing app or video that rapidly cycles colors
Run the color-cycling video for 10 to 30 minutes
Apply very light pressure with a soft cloth while the screen is on, if the pixel is stuck
Turn the screen off and let it rest for a few hours
Repeat the color-cycling process if needed
Check the laptop warranty or manufacturer support
Replace the screen if the pixel remains permanently dead
