Iiyama monitor only does 60 Hz on my ATI Radeon computers

    Hey all, think this is the best newsgroup for this question.

    I've got three computers and am having trouble hooking up an Iiyama
    Vision Master Pro 400 (A701GT). The monitor is coming of computer 1
    and should go on computer 2. Computer 3 is just another workstation.

    When I have the monitor hooked up to computer 2 (AMD Athlon XP 2800+
    w/ ATI Radeon 9600 Pro) I can select several refresh rates but no
    matter which one I choose the refresh rate is always 60 Hz. It's
    pretty apparant with white backgrounds and is also the frequency the
    monitor itself reports on the OSD.

    This computer (2) is running Windows 2000 Professional and I've tried
    the Standard Monitor driver, the Plug and Play monitor driver and the
    Iiyama drivers which I downloaded from the Internet from Iiyama

    On the original computer where it was hooked up (computer 1) it works
    like a charm and I can select 85 Hz and it runs 85 Hz (noticeable
    better and reported by OSD). This is also Windows 2000 Professional
    but the machine is equipped with a Matrox Productiva card.

    This is where the third computer comes in. It's a AMD Athlon XP 3200+
    w/ ATI Radeon 9500 Pro running Windows XP Professional and it has the
    same problem as computer 1. I can select different refresh rates. The
    screen blinks to black momentarly and comes back with Windows asking
    me if it's ok. But it's still always 60 Hz.

    I've googled and searched the news groups, but can't find this problem
    anywhere. It really looks related to the ATI cards.

    TIA for any advice and/or solution (except buying a new monitor ;)

    Hey all, think this is the best newsgroup for this question.
    Any guess what: after hours of fiddling and trying to get it to work.
    Five minutes after I post I to a newgroup I find the fix:

    The refresh rate setting on the monitor tab in display settings does
    not influence the refresh rate of the monitor. The setting that does
    influence is, is the one on the ATI tab Displays where I noticed the
    monitor hookup and it said 60 Hz. Switched it over to 85 Hz and it

    Perhaps this is of some use when indexed by Google for future
    generations ;-)

    I surprised you didn't find it, since it is commonly reported. I had
    the same problem recently, and you can override the 60 hz limit,
    but you have to go pixel hunting in the ati control panel to find
    it :).

    Here's the sequence on my Windows XP system:

    Right click on desktop background
    Select "Properties" from popup menu
    Select "Settings" tab
    Click on "Advanced"
    Select "Displays" tab (NOT Monitor).
    Click the word "Monitor" in the thing above the picture of a
    monitor which looks like it is merely a artsy shaped heading
    with a bite out of the left side, but is actually a button
    that brings up another dialog.
    Finally! On the "Attributes" tab there are controls
    to select max refresh rate, resolution, etc.

    There are adventure games with puzzles that are easier to solve than
    this - a true testament to ATIs interface design :).

    I've googled and searched the news groups, but can't find this problem
    Thing is that I have been running an ATI radeon in computer 3 for
    almost a year and I can also set the refresh rate in the ordinary
    Windows monitor tab in display settings. Apparantly this doesn't
    almost work.

    It's fixed now :)

    Just for future reference: I've got the same problem here. I always
    used to run my desktop on 1152x864 at 75 hz on my Philips 107S

    Since I've got a Sapphire ATI Radeon 9600XT, it only does 60 hz.
    However, the display properties (monitor tab) in Windows says it runs
    at 75, the OSD on the monitor says it is 60 hz...
