I fear it's quite common that the first line supporters are only trained to
deal with "standard" issues.
I'd recommend the following procedure:
1. Re-install everything (Vista 64, nvidia driver and GXM tools, potentially using
a different hard drive), run the GXM wizzard, select the 5040x1050 mode.
This will demonstrate you have a "clean" system. Make sure to document the
software versions you are using.
2. If you still get blank screens, then do your magic to capture a screenshot of the
settings. Then install Linux or WindowsXP and check if your setup works there.
If it works on Linux/WindowsXP but not on a cleanly installed Vista system then
this proves that
a) your setup is technically ok, and
b) there is obviously something wrong with the GXM tool, probably in
combination with the nvidia driver.
I guess a detailed bug report will break the first line support and propagated
up to higher support levels.
