Release 331 Graphics Drivers for Windows - Version 331.82 RN-W33182-02v01 | 20
Known Product Limitations
 If HDMI-HDTV (Audio Disabled) is selected and you want to test whether your
HDMI audio does, in fact, work, then select HDMI-HDTV (Audio Enabled) and the
driver will prompt you with instructions for testing HDMI audio with the display.
 If HDMI-HDTV (Audio Enabled) is selected, then the driver has not successfully
detected that an incompatible display is connected.
Future drive versions will properly identify such displays and disable audio.
 If there is no HDMI connector option in the NVIDIA Control Panel->Change
Resolution page, the display does not support audio and has properly reported this to
the NVIDIA driver.
Using HDMI/DisplayPort Audio in Dualview or Clone Mode
Configurations
Two Audio-enabled Ports
In a multi-display configuration where both HDMI/DisplayPort audio ports are enabled,
only the primary display will provide the audio.
One Audio-enabled Port
In a multi-display configuration where only one audio port is enabled, such as when one
display is a DVI display, then the HDMI/DisplayPort display can provide the audio
whether is it the primary or secondary display.
GPU Runs at a High Performance Level (full clock speeds) in
Multi-display Modes
This is a hardware limitation and not a software bug. Even when no 3D programs are
running, the driver will operate the GPU at a high performance level in order to
efficiently drive multiple displays. In the case of SLI or multi-GPU PCs, the second GPU
will always operate with full clock speeds; again, in order to efficiently drive multiple
displays. Today, all hardware from all GPU vendors have this limitation.

Performance Group version 6.03.06.00
The GeForce GTX 295 fan control does not function properly when using the NVIDIA
Control Panel Performance Group version 6.03.06.00. For proper fan control, use version
6.03.12.00 or later.
