    My Vista 64 desktop lowers the resolution of my monitor by itself and
    scrambles the icons, is there a fix for this?

  2. You'll have to give us a bit more detail, Dave. What monitor, what video
    card, and in what situation does it change the resolution would all be
    useful information.

    Dave,
    In addition to the data requested by Charlie, does your monitor "disappear"
    from Device Manager when this issue shows up?
    How to you get the resolution back to the normal state?
    In the meantime, this msft "oldie" (still works up to Windows 7)
    http://support.microsoft.com/kb/311272
    can patch (not fix) the problem you mention.
    Just run devcon.exe with no parameters and check if normal resolution is
    restored.
    Trying won't hurt.
    I have to do it from time to time when my screen resolution drops down after
    resuming from standby or when waking up the monitor.

  4. This is after you are done playing a game by chance?

    I experienced this in the RC. Cured it by d/ling the latest video drivers
    for my card & windows 7 64. Probably the same for Vista.

    Here is more info:
    I have a 24" Gateway monitor,FPD2485W, and the video card has been both an
    onboard ATI HD3300 Radeon and an external Nvidea GeForce 6800, both do it
    and I cant pin down exactly what precedes the problem, its after a shutdown
    and happens maybe once a week. Its shutdown and restarted maybe 2-3 times a
    day. The devices dont drop out of device manager as far as I can tell, they
    are always there when I check it.
    I looked at the devcon thing and am not sure what it is, I will look into
    it more.
    Thanks for the help and suggestions.

  7. Disable the onboard video in the bios. You can't have both and not expect
    possible conflicts.

    Dave,
    devcon forces hardware redetection (quite fast, no reboot, just a few secs).
    It does the same job as "Search for new hardware" option in Device Manager.

    I found out that it happens after a reboot with out the monitor being on the
    system. I have a switch to switch the monitor & keyboard between 2
    computers. If I reboot the Vista X64 machine with out the monitor/keyboard
    switched to the Vista machine it will do this, I have to reinstall the
    correct video drivers to correct the problem. I think if Vista doesnt find a
    monitor it will install some default video drivers, which are the wrong
    ones? It didnt do this on Win XP.
    I am using an external video card and the onboard video is disabled during
    all this.
    Thanks
