I bought the sam motherboard, listed was the ability to run dual
monitor.....which was one of the main reasons i went with this mobo.
although now that i have it i can not get both of my monitors up on it.
i am using Win Vista premium 32bit, and have DVI connected on my main
and VGA on the second but for some reason it is not working, i tried
everything available to me in the Nvidia control panel as well as the
display settings offered by windows....any ideas? my main monitor is a
ILO 24in HDTV with DVI support and my second is a Viewsonic with both
VGA and DVI. i installed drivers for the viewsonic and still come up
blank. anyone else have this problem with this Mobo?
You might not be alone.

A possible explanation, is one of the monitors does not have a
working and error free EDID table. EDID is monitor information
passed over the serial DDC/CI interface on the monitor cable.
The info travels from the monitor to the video card. The Nvidia
driver may be quite strict about checking it, before
accepting the display.
You can check whether each monitor has an EDID (for Plug and Play)
using this tool. The "raw data" depicted in the screen shot here,
is an example of what the video card uses, to assist it in figuring
out what output resolutions are safe. (The monitor driver does the
same kinds of things, but what I cannot tell you, is whether
the monitor driver completely eliminates the need for a
valid EDID. A thread I was reading just yesterday, someone
had a monitor with a bad checksum on the EDID, and the Nvidia
driver refused to output a signal to the monitor.)

There are other tools for reprogramming the EDID chip
inside the monitor, but if the chip is read-only, you
cannot reprogram it. In any case, you shouldn't need to
do that.
You might also see if you can borrow another monitor,
try some different brands, and see if the results are
still the same.
