I have my setup in a living room that is rectangular and as such can only watch stuff on the short length of the room. I have a electric ceiling mounted 2m wide screen and a Panny AE500 on the ceiling at a distance of around 9-10 ft away from the screen, I also sit beneath the pj so the distance is the same and it is wonderfull. Playing games on it is stunning via the xbox 360 and films etc are superb. Even at this distance from the screen I cant see any screen door effect and very minor
VB but it aint enough to even think about tbh. I should imagine a Z4 or similar will not have any of the probs like that though.
