What a purple screen tests
Purple is one of the most useful diagnostic colors because it drives the red and blue sub-pixels hard while leaving green almost off. On a healthy panel the purple looks even from corner to corner. If you see greenish patches, the red or blue channel is weak in that region; if the purple looks patchy or banded, the panel has a uniformity problem that white and black tests can miss.
Wide-gamut OLED and quantum-dot displays sometimes oversaturate purple into neon. That is a calibration choice rather than a fault — compare against violet #8F00FF and lilac #C8A2C8 above to see how your panel renders the whole purple range, then check the other channels on the 8-color screen test.
A purple tint appearing over everything is a different problem — usually a loose cable or failing backlight on older LCDs. If your whole display looks purple during normal use, run the monitor test patterns; if the tint follows the test colors, the panel or cable is at fault, not the content.

Why test a screen with purple?+
Purple mixes red and blue while skipping green, so any panel weakness in those channels shows up fast. Faint green patches or blotchy purple regions indicate uniformity problems or a dying backlight zone.
