Visualizer & HDMI (Projector)

[Coogan]

Hi there, got a question about the visualizer.
I'm using two monitors, primary & secondary.  Both are hooked to DVI, no problems there.
I have a third connection, a projector hooked to my HDMI @ 1920 x 1080.  I'd like the visualized to start on the HDMI screen at the same resolution.  For some reason
the visualizer is starting at a very different resolution than the projector is set at.  It cuts off half of the visualizer.
Does any one have any advise that may help?
(I have the projector set to 1920 x 1080 in the Nvidia Control Panel)

Thanks.
