    CRT Monitor locked at 60hz.


    Hi, I just bought a new PC but I didn't buy a monitor. So I hooked my new rig to my old ADI Microscan 15 inch CRT monitor (don't laugh and I don't remember the model number). Now the refresh rate is locked at 60hz even if I uncheck the "Hide Unsupported Modes" option. With the old rig I could normally set the refresh rate to 85hz (maximum supported mode), but now I feel some very slight flickring with 60hz.

    Specs for new rig: Intel Dual Core 2.6, 4GB RAM, XFX HD6670 DD3 1GB, Windows 7.
    Old rig : AMD Athlon 1.4, 512MB RAM, Geforce FX5500 256MB, Windows XP SP3.

    The refresh rate is locked regardless of screen resolution. My current is 1024x768.

    I tried the Catalyst Control Center but it gives me only 59hz, 60hz.

    The HD6670 has a VGA port so I connected the monitor directly without having to buy a converter (If it was a possible point of debate).

    Any help would be appreciated.

    Thanks.

    Right click your screen and bring up Screen Resolution. Click on Advance Settings. Select Adapter tab and at bottom select List All Modes then select what you want and see if it changes.

    I googled Aero but I find it's not available in the business edition of Windows 7.

    There is no such thing as Win7 Business edition, only 4 versions...

    Win7 Starter
    Win7 Home
    Win7 Pro
    Win7 Ultimate

    Try this...

    Disabling Aero for Windows 7
    • First, you’ll want to right-click on the desktop and choose Personalize from the menu.
    • Then you can simply scroll the themes down until you see the Basic themes. Choose any of these basic themes and aero will be off!

    I tried that but ALL MODES are stuck with either 59hz or 60hz

    One thing I forgot to mention is that my monitor is defined as "Generic Non-PnP Monitor". I remember it was "Plug & Play Monitor" with my old system. I also remember It didn't have any drivers CDs when I got it. Is there a way to identify the model number so I may find the proper driver from the Internet?

    There's your problem! Find the correct drivers for that monitor and all should be returned to normal!:)

    Wow, the disc had "Windows 7 Buniness Edition" written on it. I right-click My Comuter to find it's Pro edition . I bought that version at a reduced price as part of some MS project to help college students afford Windows. But apparently the guys there don't know what they're doing. Anyway, I disabled Aero but no luck. Still stuck at 60hz.

    Does it have a sticker anywhere on it with any information?

    Does it look like this one.

    After great physical effort, I located the model number of the old lady. It's an ADI Microscan V57. Now I downloaded the so-called "V57 Driver" from ADI official website. But all I get is a PDF manual and an INF file type. I don't know if the INF file can be injected somehow into the system. Now I stumbled upon a little tool called Refresh Lock that apparently can change the monitor's refresh rate . I wonder if anyone used it and if it's safe?!
