Catalyst 5.7 Still Doesn't Work Correctly on Non Standard Monitors

    There is a bug - still not resolved in Catalyst 5.7 - where if you are using
    a non-standard monitor the Catalyst drivers will allow you to set the full
    resolution of the monitor but will not allow you to change the display
    properties. Without the ability to change the display properties, the
    desktop is stuck at 1600x1200, and higher resolutions must be mapped as a
    virtual desktop to the lower resolution.

    Normally you overcome this misfeature by setting the display properties
    manually in Catalyst, and then the physical desktop expands to full size.
    If you have a non-standard monitor however, Catalyst will fail to recognize
    it, and under display properties you see the monitor disconnected, and you
    are therefore not able to set its properties.

    ATI should add a checkbox on the display properties - or on the
    troubleshooting button from that page - that forces recognition of the
    display. That would let the user override the default buggy behavior.

    You call this a bug; some idiot at Microsoft WHQL-testing calls it a safety
    feature. It prevents the ignorant user from using a non-supported res or an
    excessive refresh rate, which can damage the monitor.
    Normally you overcome this misfeature by installing the custom INF file that
    comes with your monitor. INF files can be found either on the manufacturer's
    web site or a repository like http://www.monitor-drivers.com/ . Otherwise,
    google for it.
    Have you tried the utility Powerstrip?

    I did try a few INF variants with no luck. I will try the site you
    reference as well, but at this point I am afraid to touch the system because
    I got it to work through invoking a set of bugs that had desirable side
    effects, and I doubt I could duplicate the sequence if you paid me. :)

    Can you send the URL?

    Thanks for the references.
