Why gray matters
Gray sits between black and white, so uneven brightness and color tint can be easier to see. It is useful for checking large monitors and laptop screens.
It can also reveal streaks after cleaning because smears often show clearly on mid-gray.
How to inspect
Open fullscreen and sit at your normal viewing distance. Look for patches that are warmer, cooler, brighter or darker than nearby areas. Some variation is normal on many displays.
