For a projector in a light walled room then I'd say 2.2 gamma, particularly a projector with fairly low native contrast as the one in your signature. If you use 2.4 you generally need a dark walled room and a projector with good native contrast (ie 30,000:1 and above perhaps). Otherwise you're likely just to suffer from poor shadow detail.

If it's a TV your talking about, this is wrong section ;) , but you may be able to use 2.4 provided you tend to watch in low(or no) light.
