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 :p 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.

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...

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 :confused:. 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.

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?!

Right click the inf file it should have an Install choice. You can also open it to see what it is doing.

It didn't work! :(

The right-click-install gave an error message. However I was able to choose the INF file manually using the Monitor's "Update Driver" button in Device Manager (a solution I got from sevenforums :p), thus displaying all available drivers in the INF file. Strangely the V57 model wasn't there. but the V77 was there and the only difference between them is the size (V57 15in, V77 17in). So I chose the V77 anyway making the monitor identified as "Display device on:VGA" instead of "Generic Non-PnP Monitor". Same 60hz

I also found the option to install the monitor as "Generic PnP Monitor". This added many "interlaced" modes with refresh rates between 25hz and 30hz.

Hmm. 2 days and no reply. Now I officially lost hope. However after some searching It's probably the video card driver. Something with Windows not letting the driver overriding the EDID settings, and manufacturers not doing anything about it. Could someone at least verify this?

If the video card is identified correctly and the monitor isnt... I'd say (educated guess) :sarc: that it is an unsupported Win7 monitor.

After all. most of us dumped CRT's years ago... and sorry, but ADI isnt a name that comes to mind when I think monitors!

If you have access to another video card, certainly try it... but I highly doubt anything will change! Honestly, I'd look for a more modern monitor first! If $ is tight... look to eBay or Craigs list!

Thanks for the help everyone. I know the monitor is ancient but I noticed that a lot of people are intentionally using CRT for gaming because of the higher refresh rates (I'm a gaming :geek:). But since mine is stuck at 60hz I'm better off getting a modern one anyway. I just need the green light from the $ :p.

Solved!!! Finally :D

I was toying with Catalyst Control Center and I found a little setting under the My VGA Displays tab -> Properties (VGA Displays) called "Use Extended Identification Data (EDID) or driver defaults", I unchecked it and I was able to set the maximum resolution and refresh rate manually, thus overriding the Windows settings. It was hiding in plain site!. I must've been blind. I was always looking in the Desktop Management tab -> Desktop Properties in CCC. Wow. Just wow.

Thanks again everyone.

Solved. :)
