Press Go full screen and look across the whole display. Press Esc or click Exit full screen to return.
What the results mean
This pink lights all three sub-pixels, with red strongest, so a dot that looks wrong here could be any of them. Its pale tone makes a greenish or yellowish patch on part of the panel easy to spot.
Common questions
What is a pink screen useful for?
Mixed colors expose tint differences across a panel better than pure ones. Pink in particular makes a greenish patch obvious.
My screen shows pink on its own after a drop.
A pink or magenta tint that appears by itself usually means a damaged panel or cable, not a software issue. This page can't fix that; it only shows a solid color.
Can I change the shade?
This page uses one fixed pink. The purple and red pages give you neighbouring colors.
