I would just like to say - my first pj has been a 4805. it has been set up (fairly) properly - and i have got to say that after many many films it is a fantastic projector - i still smile every time i turn it on! yes on occasion on areas of similar colour i can see screen door even at nearly 2.5 times screen width (1.85), but it really doesnt matter, watch the film! its amazing, its far better than the cinema! rainbows -yes i did see them - they do seem to have dissapeared tho! i know other people have talked of this - i was v sceptical - i almost threw the pj away in disgust cos of this when i bought it! (demo'd - didnt see them - at home saw them straight away!) i just had to say that for what is a budget pj it has created a superb cinema experience for me and i can be quite picky! P.
