RefreshDisplay
Normally, most of the drivers do not update the whole display, but
only the areas that have changed since last update. So it might be,
that some faulty pixels would stay a longer time. To avoid this, the
plugin makes a complete refresh from time to time. This parameter
defines how often a complete refresh will be done.
e.g.: A value of 5 means, that the plugin will make a complete
refresh on every 5th update.
A value of 0 completely disables complete refreshs.
Possible values: 0 <= x <= 50
Default value: 50
