Setting driver options
You have these two choices for setting driver options:

The Disable DirectDraw option has specific conditions that

choose this option.
To disable DirectDraw
In the Driver Options field, select Disable DirectDraw.
Click Apply or OK.
DirectDraw is an API that allows direct manipulation of
the video display. DirectDraw applications expect the screen
to be represented as a single element. If you are using one
M2/PCI board with multiple screens, or multiple M2/PCI
boards, more than one screen represents the Windows NT
desktop.
With multiple displays representing the Windows NT
desktop, DirectDraw applications cannot access the entire
desktop and may not work properly.
