I tried this on an 9020SFF with a Nvidia quadro 510. Everything seems to work great except a couple of minor things.
The computer is connected to a Sharp 40 LCDTV via the DP adapter supplied with the video card. With the resolution set at 1080P there is underscan, and selecting in overscan results in too much with the menu bar at the top and bottom clipped off.
I tried a couple of things, this script here
The script says it can't find the parameter in the file (/var/db/.com.apple.iokit.graphics). The author gave some suggestions but they did not work.

Gives a similar error about not being able to find the parameter in the file (/var/db/.com.apple.iokit.graphics)
I also tried switchresx, but so far have been unable to find a correct resolution to set. In windows, I can set underscan and the display works correctly. I tried the resolution set from that in switchresx and it did not work.
The second thing is the audio seems to default to headphones each time the system is booted up. I have to switch the audio to sharp hdmi and it works fine from then until the next reboot.
