Use-case page
This black screen for cleaning monitor panels makes dust, lint, fingerprints, and smudges stand out. Use it as a fullscreen screen cleaning tool before wiping your display.
Start cleaning mode
A fullscreen black screen to see dust is useful because dark backgrounds make fine debris and oily marks pop out. Start with black, then switch to white to confirm you removed streaks cleanly. If you also check panel quality, the related dead pixel and HD pages below are a good next step.
A black screen for cleaning helps you slow down and clean only where needed instead of wiping the whole display aggressively.
Black is usually the best starting point for dry dust and lint because particles stand out against a dark field with less glare from the page itself.
If you are already cleaning the panel, it is a good time to run the dead pixel test and then compare the screen on the HD, 1080p, or 4K pages depending on your display.
Cleaning benefits
This use-case page is built around the primary cleaning workflow, but it also helps you move into display testing once the panel is clear.
