Dual display differences between Windows NT 3.51 and 4.0 Dual display differences between Windows NT 3.51 and 4.0
Due to the way Windows NT implements desktops under these two
versions, dual screen operation differs slightly in the way application
windows behave when maximized and where system dialog boxes
appear. Under Windows NT 3.51, when an application is maximized, it
is maximized to one full screen size whereas under Windows NT 4.0,
the application window becomes the size of both screens. However,
once an application is created, it can be moved to any screen and can
be resized to span both screens. A maximized application can be
moved but not sized unless changed to its non-maximized size.
Under Windows NT 3.51, system dialog boxes are centered on the
“primary” screen and the task manager appears on this screen. In
Windows NT 4.0, the system dialog boxes appear straddling the two
monitors and can be moved. In addition, the task manager can appear
anywhere on the screen when running Windows NT 4.0.
Oxygen control panel dual screen operation Oxygen control panel dual screen operation
The control panel applet that is shipped with your Oxygen card allows
you to disable the dual screen operation, in cases where you only want
to use one display. When disabled, one display is operational and the
other display is blank. After disabling this option, Windows NT must
be restarted for this change to take effect.
This option is provided so that one of the Oxygen cards can be used at
resolutions other than 1024x768 without having to remove the second
Oxygen card. Once the dual screen option is disabled, it has to be re-
enabled with the control panel applet before both the screens are
operational again.
This option is grayed out in the Oxygen control panel unless there are
two Oxygen cards detected in the system.
NOTE : The Oxygen Status page in the Oxygen control panel will show
how many Oxygen cards are detected. For more information, refer to
the
Oxygen Control Panel section on page 24.
