FAQ
Can I test my monitor on any device (desktop / laptop / mobile)?
Yes, though the experience is best on larger screens and desktops. Some test patterns may be harder to evaluate on smaller/mobile displays.
Does it require registration or payment?
No. It’s free and does not require you to create an account.
Will it damage my eyes if I leave full screen for too long on bright colors?
Bright colors in full screen can be harsh. Use short intervals, reduce brightness, or look away regularly.
What should I do if I find stuck or dead pixels?
Depending on your warranty/monitor brand you might get replacement. Sometimes pixel massage tools help, but results vary.
