I'm running Premiere CS5.5 on a MacPro with a newly installed Nvidia Quadro 4000 card. The video and CUDA drivers from nvidia have been installed properly I believe. But when I'm in premiere and setting up a new project the drop down options for Renderer are non selectable. The only option is "Mercury Playback Engine Software Only."
When I connect my monitor to the nvidia card, I'm using the HDMI port and a HDMI>mini-DVI adapter. Could that be an issue? Should I be connected directly to the full size DVI port on the card?
