Good to know
Black as a display test
Ideally, a black image shows no light spots at all. Test in a dark room at medium brightness to judge backlight bleed and IPS glow realistically.

Switch between the white and black screen to get a feel for your display's contrast range. It does not replace a measurement, but it quickly reveals obvious weaknesses.
