Update - had the GT750 about a month now. - Turns out that plugging headphones directly into the audio out causes distortion. Connecting to a hifi and plugging headphones in to that works fine. - Bought a Panoview DP-9080MWL 80" pull-up screen to use with the projector. Works really well without having to drill into the walls, would recommend this for anyone in a rented house! - I noticed that the focus changes a bit while the projector warms up, so it's best to set focus after 5 mins or so. - I'm now using the component and S-Video connections as well as HDMI, works well!
