When multiple displays are configured in 3D Vision Surround mode, clocks should drop to idle levels when on the desktop. If clocks on your card are not dropping, check the following:
- Confirm the display refresh rate is set to a maximum of 60Hz in the NVIDIA Control Panel under Change Resolution. Note that full screen games can still be run at 120Hz even when the desktop is set to 60Hz.
- Confirm that no 3D applications are running that may be putting load on the graphics processor. This can include performance utilities, video, and other applications that use the GPU.
