MAtrox G450 PCI card in Windows 7

[Harry_PC]

I have a matrox G450 PCI Graphics Dual VGA card. This is working fine in a Windows 7 Ultimate 64 bit SP1 system. I now want to reinsatll Windows on a SSD and although the new installion is fine, I cannot get the G450 to work in dual mode. Both screens do work, but they show the same screen. I cannot find any drivers that will successfully load.

The Driver Details are shown in Device Manger as
C: \Wmdows\system32\DRIVERS\g400dhm sys
C: \Windows\sy3lem32\g400dhd dll
C: \Windows\system32\MtxCIP2 dll
C: \Wlndows\Sys\WOW64\PDesk\puninst.exe

Thank You

Don't you have the "Extend" option in the Windows settings?

Yes this is there using the HDD which has the card working. But when I try and install the driver, on the new drive (SSD) the installation fails. The screen resolution window you refer to shown only one screen, and both monitors show exactly the same image, as if there is only a single monitor attached to a card with a single head.

Force "update" the driver from Control Panel > Hardware, using "have file" option and pointing to the location where old drivers was saved.
