I have hooked up a 3d projector to a gtx 550ti via DVI->HDMI adapter and i can get full 1080p 3d @ 24hz. I decided to hook up the HDMI out (on the nvidia card) to my 1.3a receiver (onkyo sr705) for HD sound. So far I can only get DTS and dolby (as the option for HD sound is not there in powerDVD 12). Also under "supported formats", i see just DTS and dolby.
Reason why i hooked up the DVI out to the projector is because the HDMI ports on the graphics card doesn't recognize my projector as a 3d projector for some reason.
Should I get another DVI dongle and output HD sound or the HDMI out should work? Do you guys see other things under "supported formats?" (under properties)?
