This is a
dual-monitor system configuration
The program generally detects dual-monitor systems
by itself and accommodates its appearance automatically. However, if
your dual-monitor system does not work entirely through Windows and
relies on video drivers for that functionality, then the program will
most likely be confused. By enabling this option you will explicitly
tell the program that you have a dual-monitor system. This solution
should work fine for majority of dual-monitor configurations, but there
is no guarantee it will work in all cases.
NOTE: You have to position both
screens so they are leveled at the top with primary screen on the left.
Any other set up will cause the
program's interactive desktop feature to not work correctly.
When this option is enabled you will get the same
wallpaper on both screens in a dual monitor configuration. However, for
this option to work properly both screens have to have the same
resolution and they also have to be leveled at the top with primary
screen on the left. Any
other set up will end up with some unexpected result.
