Hmm... with the firmware I have (which is a bit old), it only says Dolby True or DTS MA... with nothing on the sample rate. And I mean it shows both with the "or", it does not show which precisely. However, if you have it hooked up a certain way with your receiver, your receiver OSD should be able to show you. I have all my video inputs going to my Duo, then the Video out (not the audio only out) is hooked up to HDMI input 1 on my Onkyo. The Onkyo is then hooked up to my display. I get both on screen displays this way.
