I tried to do that with my phone and there was no way to get it show full screen without it distorting extremely. So, I think laptop & HDMI is the way to go. But I'm sure it's only a matter of time before someone gets drunk and trips over the cord, spilling beer all over the table and frying my laptop.
One other thing I noticed is while using the D&DB app the Maps feature isnt available on my iPhone or my Amazon Fire Tablet. The tools menu is not there that I can find. While trying to access the tools menu on both devices with an internet browser, the Tool menu is there but the Maps feature is not.
