White screen to clean your monitor

Steps

1. Open Instant White on the display you want to clean.
2. Tap Clean monitor (full white).
3. Enter fullscreen so bezels and menu chrome disappear.
4. Wipe with an appropriate screen cloth; re-check on white.

Tips

• Power off if you use any liquid near ports — then re-open white to verify.
• Gray or black fields can help spot different residue types.
