NAME
lcdscrub - attempt to repair burn-in on LCD screens
SYNOPSIS
lcdscrub [-display host:display.screen] [-visual visual] [-window]
[-root] [-delay number] [-spread number] [-cycles number] [-fps]
DESCRIPTION
This screen saver is not meant to look pretty, but rather, to repair
burn-in on LCD monitors.
Believe it or not, screen burn is not a thing of the past. It can hap-
pen to LCD screens pretty easily, even in this modern age. However,
leaving the screen on and displaying high contrast images can often re-
pair the damage. That's what this screen saver does.
