• nView Dualview, Span, and Clone modes support advanced NVIDIA
features such as
Video Mirroring
. See
Note:
Windows NT 4.0 in Multiview mode does not support Video
Mirroring.
• Windows places the taskbar on only a single display.
• Windows replicates (rather than stretches) the background on each display.
• When you maximize an application, it maximizes only to the single display,
and so on.
shows an example of a Dualview system where the left display is
running at 1280x1024 and the right display is running at 1024x768. Notice
that the background is not stretched across the displays and the taskbar
appears on a single display instead of being stretched across displays.
• You can set different color depths per display.
• You can arrange your multi-display desktop to be any shape; it does not have
to be limited to “rectangular” as in Span modes.
• When you run a DirectX or OpenGL application in Dualview mode, it is
accelerated as long as the window does not span more than one display. If the
window spans two displays, drawing is not accelerated in the window.
Note:
In Span mode, drawing is always accelerated.
• Dualview mode works for any display connected to your NVIDIA multi-
display graphics card:
•
PC monitor with an analog connector
•
Flat Panel with a DVI connector
•
TV with an S-Video connector.
For example, you can have a system with the primary display as an analog
PC monitor that supports up to 1600 x 1200 at 100 Hz refresh rate, while the
secondary display is connected to an NTSC TV that is limited to 800 x 600 at
60 Hz refresh rate. The TV has less resolution and refresh rate than the
monitor since the TV encoder on the graphics chip has fewer capabilities
than the analog PC monitor.
