Two monitors - One of them not working

Hi! Can anyone help me solve this problem please?

I have no problem making my two monitors work in Windows XP. However, after
I installed Vista, one of the monitors remains black. I have not unplugged
anything or in any way changed the connections. The only change to the
computer is that Vista has been installed, so I reckon the problem has to do
with the driver.

I use a Matrox Millennium G550 graphics card for a dual head (monitor)
solution.

Downloading and installing the driver marked as DualHead2Go on this web page
did not solve my problem:

P.S. There are no yellow question marks in the device manager.
 
Did you go into the display settings, and enable extending your desktop to
the second monitor? In almost all cases people need to manually enabled the
second monitor somehow.
 
Same problem here:

Windows Vista Beta with Asus motherboard P4C800 de luxe and Matrox G550 in
AGP.

Matrox G550 running fine on one monitor but second one is not detected. Both
are the same ones and run fine under XP.

May be related:

I got an optional update on windows update for the Matrox card (st00%%EN)
but it doesn't install.
Always fails.

In device manager: When I remove the current Matrox driver and restart back
to VGA, it automatically finds a Matrox driver.and says I am up to date.

In Windows update the optional Matrox driver keeps being shown as available
update, downloads it again but never installs properly.

1. Did anybody here got the Matrox G550 working in dualmonitor setup?
2. Did anybody got the Windows update/install for the card properly
installed?
3. Where doe the DL updates and temp files go now? (in XP they where
visiable in the Windowsfolder with $xxxxx)
4. Is there a way to completely clean al related drivers for Matrox,
download the update and (manual) force Device manager to use it?
 
Ok found a solution, which means it is possible to use dual monitors with
the Matrox G550 card and Vista beta 2

After a few times trying to install the windows update Matrox driver (failed
everytime) I set the display driver back to VGA, without restarting.
Then again I choose ":update driver manually" in the device driver and found
more than one driver available on the computer. Apperently the windows
update placed the right files somewhere but could not install properly.
So I choose the Matrox G550 Series driver (instead of the Matrox G550
Millinium as before) and restarted
After rebooting an little PDESK icon appeared in the tray and there I could
enable the second monitor.

Works like a charm now!
Hope other people can use this solution too.

I've had no luck at all with my ancient Matrox Dualhead G440. Every driver I
downloaded crashed at booup. No sign of PDESK anwhere here. Did you already
have PDESK installed because you upgraded, or did you install it yourself?
 
It installed with the Vista drivers I think. It is clearly different from
the old XP version.

Unhook the monitor that remains black. All the monitors on your system will
them be working. Problem solved!
 
What do you mean with "unhook"? Disconnect and reconnect? Sorry, but
it's my English.

Thanks Linus
