I have 3 imacs in my office and am looking to connect them to my samsung tv so i can use it as a 2nd screen for presentations, or general use as a 2nd screen. can i do this with Apple Tv?
also, one imac has minidisplay port and the other has thunderbolt ports. not sure which models they are.
if the mac is running mtn lion and it's new enough to support airplay mirror you can clone the imacs screen never make the tv a second desktop
if you want second desktops you need to use the thunderbold / minidisplayport (it's the same connector) to hdmi converters
