Enable DirectDraw
This option allows the user to enable or disable DirectDraw.
DirectDraw is a software interface that provides direct access to
display devices while maintaining compatibility with the
Windows graphics device interface (GDI). DirectDraw provides a
device-independent way for applications to gain access to the
hardware features of specific display devices. If you enable
DirectDraw, your application will have the choice of using
DirectDraw or GDI. If you disable DirectDraw, your application will
use GDI instead of DirectDraw. Please note that in any case, your
application can always use BarcoMed driver functions (i.e.
WinBarco) or other graphics extensions (such as OpenGL).
Monitor Configuration
If the options in this section are grayed out, then they are not
available for the model controller with which you are working.
Under Windows 2000 and Windows XP you can enable or
disable DualView through the drop-down menu.
In SingleView mode the Monitor Configuration section allows you
to select the number of monitors that the current display boards
should drive, as well as how the monitors should be positioned.
For example, if the current board installation is capable of
driving four heads, but you only have three monitors which are
placed in a single row, then you can select the “Three
monitors–one row” option from the pull-down list. This would
cause the Windows virtual desktop to be resized to fit on the
three monitors, and you can move your cursor horizontally from
one screen to the other. If “Custom Configuration” is displayed, it
means that the current monitor configuration was set via the
registry and it doesn’t agree with any of the configurations that
the display control panel supports. Contact Barco Medical
Imaging Systems for further information.
