I'm not messing with you, I swear. I just quadruple checked it on a fresh Mint 16 install and had the same result:
Right-click on the desktop, select "Change Desktop Background"
When the System Settings screen comes up click "All Settings"
Scroll to the bottom and in the Hardware section click "Display"
I just did it and that's exactly what I got. If you're not seeing it I suppose you could be seeing a different issue but the Display settings should bet there.
