Intensity pro and Radeon 5770 ?

Hi,

I'm experiencing some problems with my Intensity Pro that I think might be due to some incompatibility issue with the ATI Radeon 5770 in my Mac Pro 3.2 ghz (Mid 2012).

With the intensity pro card installed it takes about 5 minutes to boot, and there's nothing showing on the display until the finder appears. However I've found out I can speed it up by unplugging and plugging the MiniDisplayPort to VGA adapter back in. When I do that, I immediately get an image on the display and the computer starts to boot.

With the intensity pro uninstalled the computer boots just fine and there's no problems with the displays.

It's all a bit mysterious and I'm not sure if it's a faulty gpu or some issue with the Intensity Pro.

Has anyone had any similar problems ?

Thanks.

Mac Pro, OS X Mountain Lion (10.8.2)

Is the firmware/drivers up-to-date on the Intensity Pro?

Apologies for bumping up an old thread, but I am having the same issues. I had two 5770s in my Mac Pro, but have sold one and bought a Blackmagic Intensity Pro instead for use within Pro Tools 10.

I downloaded the latest drivers from Blackmagic and installed them and the card. Now when I turn my Mac Pro on, one of the three screens connected to the 5770 won't turn on unless I unplug and replug it. Practically what the OP describes above. When I uninstall the Intensity Pro, everything works fine as normal.

Was there a solution to this? Or does anyone know of one?

Thanks.
