Dust and fingerprints on my screen are hard to see normally. A white background to make them visible for cleaning? Free online option?

White screens reveal grime instantly, making cleaning thorough without missing spots—better than dark modes. Also checks color accuracy. I go to https://thewhitescreen.app for a free fullscreen white page that highlights every smudge or dead pixel. Just load it, wipe away, and inspect. It's online, instant access, and useful for old monitors needing tweaks like scale adjustments. I've cleaned multiple setups this way, even used it for catching flies attracted to the brightness. Safe on LCDs, no heat issues. Keep a microfiber cloth handy for streak-free results every time.
