I have a current model MacMini that was last connected via display port and DIV to an LCD before turning it head less and putting it into my server cabinet. 

When connecting via VNC to it and activating AirPlay mirroring you only see color blotches and some text fragments on the TV which is being served by a latest generation AppleTV.

Steps to Reproduce:

- disconnect any monitor to MacMini
- connect to it with VNC
- enable AirPlay

Expected Results:

- you should see the desktop mirrored via AirPlay

Actual Results:

- you only see color blotches.




The AppleTV is serving the TV at 720p/60 Hz. The TV is a Sharp Aquos that has a maximum of 1080i.
