Windows 7 won't let me use my SDTV as a monitor.

When I had Windows XP on one of my PC's, I was able to use my 36" Trinitron CRT as a monitor for some old school gaming, watching movies, and TV episodes with a 7pin to Component connection. It was the greatest thing for SD quality stuff, since HD stretches, lags, and gives different color quality. Now with Windows 7 my NVIDIA Driver won't let me do it the way I want to. I could do this nicely with 640x480 and 800x600 with the 60HZ refresh rate.

So. I am using a Geforce 9400 GT with driver version 181.20 (i'm sure that the XP driver might have been a lower number).

when I connected the cable to the TV, and opened NVIDIA control panel it immediately changed the settings to dualview without asking me. I switched the display to the TV and the only resolution that works is 720x480. 640x480 was not available on the control panel, but it was in the windows settings. In 640x480 it only gives me up to 30hz for interlaced. and when I change it to 800x600 it only offers up to 30hz for interlaced display. The higher ones which is 59 or 60hz are non-interlaced which wont support 480i.

Either 640x480, or 800x600 would work fine. Please help me if you can.

Thanks.
