connect 2370 to 1080p HDTV

maybe somebody else has run into and solved this problem...

I purchased a top-of-the-line 47" Vizio TV. I want to use it as the sole monitor, primarily for Windows Media Center. The TV supports a range of resolutions from the VGA input - most are 4:3 DOS through XGA. The only widescreen resolution is it's native 1920X1080 (1080p).

Here is the problem... the monitor does not fully support the DDC (Display Data Channel) function. When the TV is the sole monitor, the nvidia GO 6100 tries to set a resolution not supported by the TV. When this happens the TV only displays a message "Invalid Format", and as you can't see ANY PC image, there is no way to manually change it to the native 1080p resolution.

With a lot of dinking around, I was able to set up an Extended Windows desktop with 1080p support on the TV. But heaven forbid if a window should decide to open on the out of sight notebook - it's a pain if the cursor accidently slides off the TV onto the notebook display too.

By physically removing pin #12 from the VGA cable (I altered an adapter rather than an expensive cable), I can totally defeat DDC and Win7 treats the TV as an unknown analog monitor with a max resolution of XGA (1024X768).

I have been unsuccessful at using Vizio's published specs to create a working custom resolution, with or without DDC.

Has anyone else tried this and come up with a solution? Vizio tech support is useless. By the way, Windows Media Center is very nice at 1080p full-screen; although the USB TV-tuner can't keep up, playback of photos is gorgeous.
