You could use this to check blacklight bleeding. You could use this as a mirror. You could use this to trick your parents that the computer is off when it isn't so you can play minecraft/fortnite after midnight without having to enter the password (that u probably don't know) on your parents computer xDDDDDDDDD You could use this to check dead pixels. You could use this as a timer. You could use this to clean
