I am looking to upgrade my system and integrate it better into my lounge. Currently, I have a pull-up 70" Widescreen which I view from about 3.5m away. Whilst not exactly small it still doesn't match the impact of the better screens at my local multiplex. Is there a generally accepted optimum angle of view for a screen? I know which seats I make a beeline for at the cinema but haven't found a way of turning that into a measurement. My new projector is still undecided until I have seen a few more demos but it will be something capable of 720p native.
