    After installing Vista and trying unsucessfully to upgrade the driver to
    support dual honed monitors, have realized that the driver installation does
    not recognize the OS (Vista) and aborts the upgrade process. I don't know if
    the driver upgrade will solve the single monitor display problem I currently
    have but does anyone out there have any workarounds for this problem?

    I got my G450 Dual Head working using the MS supplied driver then installing
    an updated Power Desk.

    Used Software Explorer tool in MS Defender to remove the MS installed Power
    Desk from startup.

    Downloaded an newer XP "SE" driver from Matrox site (not specifically for
    G450). Same "OS not supported" error on install but the install did extract
    files to C:\MGAFOLD\XP2k....

    From this folder ran PDeskSE.msi to just install the updated Power Desk.
    Re-boot and was able to use power desk to enable and configure Duel Head
