orangery tv projector help

[jasoncook]

Hi all just had an orangery built at the back of the house it only gets direct sun in the morning it is 6.5 m x 4.1 m, I was considering a 60 plasma for the wall but was wondering about putting a projecter at the back and a 2m screen,so will a projector stretch to 6 m what sort of resolution can i get compared to a hd tv.The unit or the tv will be fed via sky and blue ray. Will light affect the picture using a projector vs the plasma.The budget is about £1500 I already have a surround system to fit but would like a bit of advice on the visuals Thanks Jason
