I have contacted ATI but have gotten no response. I recently upgraded to WIndows 7 and now my multiple monitors are not working because there is no driver available for my secondary video card. I see the card listed as "ATI FireMV 2250 (Microsoft Corporation WDDM)" with an exclamation point in Device Mgr.

I tried the Vista x64 driver for the card but was met with an error message during installation that I was using an incompatible OS.

I don't need any special functionality other than the ability to display 1280x1024 on a monitor attached to this card. Is there a generic driver I could use for this card? (alternate 2nd question: Is there any hope of ATI releasing a 64-bit Windows 7 driver for this card?)

Have you tried 'brute force' instead of the ATI installer?

Extract the Vista x64 driver (e.g. with Unviersal Extractor) and then install it manually via the device manager, ignoring all warnings about uncertified drivers.

Note: you should make a drive image before 'pulling such stunts'!

Edit: by 'brute force' i meant manual driver installation (Let me pick > Have Disk)

A super idea... I was not aware of Universal Extractor (that gets a point just for the sheer helpfulness for all kinds of driver installation woes :) But alas, when pointing to the extracted inf I am met with a msg: "The folder you specified doesn't contain a compatible software driver for your device. If the folder contains a driver, Make sure it is designed to work with Windows for x64-based systems." p.s. Fortunately this is a very fresh Win7 install - the only thing installed thus far is FireFox, so I don;t mind if I hos the system- it's worth it! –  Phatteus Dec 17 '09 at 11:51

I tried a number of different approaches here... an interesting point I neglected to mention initially- When I booted into Win 7 for the very first time, there was video on my third display. After a minute or so, it shut off apparently due to a driver issue.

Today I reset the driver to the Standard VGA driver and rebooted. No luck. But then I installed the same driver that was initially not working (Win 7 WDDM driver) and - wtf - it's working now. Let's hope for more than just a few minutes!

(this is actually Phatteus... my accts are screwy on this new OS installation)

You should edit your post, rather than add an answer, and you should indicate that you're not longer looking for a solution. –  harrymc Dec 17 '09 at 14:44
    
I can't edit my post- that is the issue... I can't seem to "be" Phatteus :) –  Shoeless Dec 17 '09 at 15:11
