eVGA GF 9600 GT problems with HDMI resolutions

Tried to use a DVI to HDMI cable to run a 16:9 display, and it just
won't
do it. I get overscan, or very bad underscan. Anybody else have this
problem?
I can use a GF 8600 GT in the same box, and it gives 16:9 with no
problem
at all over a DVI to HDMI cable.

Also, if I switch to a VGA adapter, and go to the VGA input on the
16:9
display, the GF 9600 GT works fine and gives a 16:9 resolution full
screen
display with no distortion.

I notice the 9000 series cards are using the same 175.xx driver in XP.
Could that be the problem? Is the 9600 a much more Dx10 Vista card?

EVGA tech support says there are several kinds of
HDMI ????????????? Meaning ?? They recommend using
an DVI to HDMI converter at the card, and then go
HDMI to HDMI on the cable ... missing wires in some
of the cheap cables ????????????? So HDMI is still
fighting the standards war ??

The middle group, allows a monitor to send its characteristics to the
computer. The data is called EDID. The two pin clock and data interface,
is a low speed serial bus. Occasionally, you'll run into cabling,
where not all possible wires are present, but doing that for HDMI
would be pretty stupid (not much savings).

To see what the monitor is sending on that serial bus, you
can try this program.

If you cannot see info coming from the monitor, then the
video card will have less info to go on, in terms of
driving a signal. One way to fix that, is to install
a monitor-specific driver, but not all companies offet
them. For example, if you went to the Westinghouse LCD TV
site, looking for a driver for when a PC drives the TV set,
they'll tell you "all our products are Plug N' Play", meaning
they are relying or DDC low speed serial interface, to
carry the resolution information from the monitor to the
computer.

That doesn't explain your problem, but hints at a necessary
component to making it work right.
