If I mirror my 27 iMac to my 50' Panasonic st50 will the resolution be 1080p? So I won't have the same desktop space as I have using the iMac with its original screen? Also, is gaming a valid option through the airplay mirroring? I've tried using plex, and I can connect my TV to the server no problem, with no lag at all playing a movie. The TV is plugged through ethernet to the router, and my iMac is connected through wi-fi, in the same room as the router and TV.
