Turning off 1 screen disables the other too

Just installed 7100 and was setting up. I have a Toshiba HDTV on DVI (display numbered 1) and an Acer lcd on VGA (labeled 2). The acer is set as the primary display and all appears fine but when I'm not using the hdtv I'd like to turn it off and just use the lcd. When I turn off the hdtv I hear the sound for disconnecting hardware and the signal is cut off from the lcd putting it to sleep.

I tried the latest nvidia drivers (oh yeah, 8600GT) and it made the system super crashy with bsod's and everything. Can I disable plug and play, which I suspect is the problem, on just that monitor?

I picked up an ATI HD4650 at work with dual dvi's. It doesn't seem to care as much which is the primary monitor. Now when I turn off the HDTV I get the same device disconnected sound but the signal comes back on on teh LCD>
