FAQ
What is a white screen used for?
Finding smudges before cleaning a monitor or TV, acting as a soft light for video calls and selfies, or serving as a makeshift tracing lightbox.
What does the black screen reveal?
On a fully black screen you can spot LCD backlight bleed and judge OLED black uniformity, and dust or fingerprints stand out on glossy panels.
How do I find dead pixels?
Cycle through red, green, blue, white and black, looking for dots that stay lit or dark. Use our dedicated dead pixel test for a guided check.
