GeForce FX 5200 dual monitor/display problem: Identical images nomatter which mode chosen.

I'm having the same problem as here:
http://groups.google.co.uk/group/al...ual+monitors+identify+as+one#97c0d65d689d062c
but the solution found does not apply to me. Let me describe the
problem:

I have just installed a GeForce FX 5200 card in order to get a dual-
display function to enlarge my desktop. Both screens are LCD; one is a
Dell, the other a MAG. They both have VGA plugs and I am using a DVI-
to-VGA adaptor to allow the use of the DVI port. There doesn't appear
to be any difference if I switch the ports ('standard' and DVI) into
which the monitors are plugged. The problem is that, although both
Windows and the NVIDIA control panel recognise that two monitors
exist, I cannot extend my desktop across the two - the same image is
displayed on both monitors at all times. I have tried every option in
the Windows display control panel as well as every option in the
NVIDIA control panel.

Both monitors are recognised (two monitors are shown in the Windows
display control panel and both, named, monitors are listed in the
NVIDIA control panel. A screenshot is here: http://www.brookwade.com/printscreen.jpg
.. Interestingly, although I only see the left hand half of this image
on both screens, if I use "print screen", the resulting image is 2
screens wide. The 'empty' area on the right hand side of the
screenshot is not displayed on either monitor.

Nevertheless, if I click on 'identify' (in either the Windows or the
NVIDIA control panel), a large "1" appears on both screens, as opposed
to a "1" on one and a "2" on the other, which would normally be the
case.

It seems to me that the problem is more fundamental than one of
drivers, but I don't know enough to work out what it is. Could it be a
BIOS thing?

Anyway, if anyone can help, I would be incredibly grateful; I've
already spent 3 hours on this!

Many thanks in advance for your time.

I'm afraid that's not the problem. I've done that and the wizard runs
fine. What I get is the same half of the dual-screen desktop on BOTH
monitors. If I change the orientation, I get the other half of the
dual-screen desktop on BOTH monitors. Basically, the computer thinks
everything is just fine. But both monitors display the same thing all
the time, no matter what I do!

 

Yes, I get clone view even when I choose Dual View. However, as I
pointed out, it is not a 'normal' clone view - the computer attempts
to spread the desktop over two monitors but displays the same half on
both. I'm convinced the machine is treating both ports as the same as
even when I choose "Only use one display (single)", I get an image on
both screens. This time, however, it is a perfect clone view as the
computer is not trying to split the desktop onto two displays so I get
the whole desktop on both screens. I'm using WinXP Pro and the driver
is 6.14.11.7519 (according to Windows' "Device Manager", although the
file I downloaded unpacked itself into the folder: Win2KXP\91.31 ).

As I said earlier, because it seems so much of a fundamental / low-
level problem, I can't help thinking it's something to do with the
BIOS. Could this be?

 

Hi,

Thanks, I'll give those a go. It might be a while till I reply but
thanks in advance for your time.
