Why can't I see Photoshop on my External Monitor?

I have an Intensity Pro card installed, and can see After Effects and Premiere outputs in the monitor, but the Photoshop picture wont show up. I read that it should install automatically with the drivers, but it doesn't show up in the import-output options in Photoshop.
Any suggestions?

CS6, Intensity Pro, HP z820 workstation

Thanks in advance

A picture is only as good as the glass it comes through. And the person using the camera has something to do with it too.
