Im looking for a decent airplay type app i can simply swipe my ipad into airplay mode with and start using a large screen for games, presentations, chat etc

I just tried Reflections and iDemo, both appeared on my iPads airplay pop up menu but failed to work with firewall on, even after adding their desktop app to the "allowed incoming connections " of the firewall app list, and what about apple TVs, im thinking about getting one for the living room and maybe also using the displays from my ipad.

any advise appreciated.
