Yeah I think you may be a little disappointed here. There is no Zone2 screen like that. I believe the reason for this is zone2 only accepts ANALOG signals - no reason for all of the fancy GUI for the limited functionality offered by this particular limitation (I have a 2113CI, maybe higher models accept digital signals, but I don't think so).
Now I have only owned this model for about a month, but like you have zone2 feeding a whole house system.
Here's what I have found so far that may or may not assist you
When you press the "zones" button (upper left of your image), you get the ability to control the second zone (which you can rename whatever you want BTW). You can select the inputs for that second zone by touching the source name on screen. This pops up a list of all your inputs. The crummy thing about this is it allows you to select both Digital and Analog inputs even though the second zone can only output ANALOG
This confused me for quite some time until I understood this limitation.
Other observations that you didn't ask for ...
I have found that the volume control does absolutely nothing, which is really frustrating. NOTE - volume does work for airplay.
I have settled on Pandora for a majority of my zone2 music these days. The Denon software doesn't do a great job with Pandora IMO, as there is no way to thumb up/down and impact the playlist with what you want. I would love a way to control Pandora via a tablet web browser and output to the Denon zone2. Maybe there's a way to do this (sort of like Apple's ability within iTunes), but I am not holding my breath. Using the Pandora interface would be a good compromise in my situation at least.
Denon software crashes a fair amount on my android device.
You can access the Denon GUI though your network and a browser. I use a tablet and simply point the browser to index page to control the AVR (http://192.168.1.xxx/top.asp
) - just plug in your AVR's IP address and you're in business. Something to consider if you'd rather not use the apple or android software (although not as pretty).
Hope this helps!
