Release 331 Graphics Drivers for Windows - Version 331.82 RN-W33182-02v01 | 22
Known Product Limitations
Display Output Selection not Available on “Bridgeless” SLI
On graphics cards that can operate in SLI mode without the SLI connector (such as the
GeForce 6600), you cannot select which monitor to display the output. On the SLI display
property page, the option box to select the output display is not available.
More Monitors are Listed in the Windows Device Manager
than are Actually Connected
 Problem
Many monitors are listed in the Windows Device Manager hardware tree even when
only a few are actually connected or enabled.
 Explanation
NVIDIA chooses to expose all potential monitors even though they are not yet
connected. Such an implementation makes multiple device handling easier in certain
situations, such as when a user unplugs a monitor and plugs another one in at a
different port.
The only impact is a cosmetic in the plug-and-play manager. There is no functional
impact at all and the GDI is not aware of the multiple monitor listing.
DirectX Fails When Detaching/Reattaching Displays in
Dualview Mode
This problem can be duplicated as follows:
1 Enable both displays in Dualview mode.
2 Detach monitor 2 and apply settings.
3 Reattach monitor 2 and apply settings.
DirectX runtime fails on monitor 1.
This is not an NVIDIA bug, but a limitation in the operating system where DirectX does not
enumerate the second device. DirectX can be restored to both displays by rebooting the system
OpenGL Viewport Scaling Problem in Horizontal Span Mode
With nView Horizontal Span mode enabled, when opening an OpenGL model in a
viewport, the model image is scaled too large to fit in the viewport. The problem occurs
with such applications as Maya 5.0 and 3D Studio MAX 4.26.
This is not an NVIDIA bug, but a limitation in the application’s ability to properly maintain the
aspect ratio in Horizontal Span mode.
