Setting monitor preferences
In the Monitor Preferences section of the DOME tab, you
can select Sync on Green, Composite Sync, and Pedestal.
If your monitor is set for these options, you should select
them here. Refer to your monitor manufacturer's
recommendations for more information.
To disable DirectDraw
Select Disable DirectDraw on the DOME tab if desired.
DirectDraw™ is an Application Program Interface (API)
that allows direct manipulation of the video display.
DirectDraw applications expect the screen to be repre-
sented as a single element. If you are using multiple
Md4/PCX boards, more than one screen can represent
the Windows NT desktop.
With multiple displays representing the desktop,
DirectDraw applications cannot access the entire desktop
and therefore may not function properly.
Screen 2 is upper-right
Screen 3 is lower-right
