    Hi There,
    Just about to finish off my 2 year long loft conversion.
    The problem I have is I have a chimney positioned about 14ft from the screen.
    When I position my 4805 I can only get a 75inch image at full zoom, and my screen is 85inch.
    Is there anything that I could do to get a full size screen image.
    NO SIDE KEYSTONE :(
    Thanks,
    Barry.

    yes but its a real pain in the you know what!!!! you can extend throw by using a mirror to reflect image on to screen, positioning of mirror and PJ are uber critical and geting a good image is even harder, never done this with DLP. But have with LCD units dont know if the mirror will create any image complications. Also you need a very high quality completely uniformly flat mirror, not easy to find!

    Was this not a consideration before you bought? On the Image Size calculator @ the Infocus site the Maximum Image size for a 13ft throw (I'm using 13ft as your chimner breast is 14ft from the screen and allowing 1ft in for the projector positioning) is 46.4(H) x 82.5 (W) and Minimum 38.6 (H) x 68.7 (W) 78 - 94 (D), so a 75 inch screen size seems reasonable. I am looking very seriously at this PJ and would be positioning approx 9.5ft away and would get a max 33 (H) x 60 (W) screen, which looks huge in the room I have. How are you finding the PJ other than your problem with screen size?

    Hi There,
    Hornydragon - I think I remember reading over at avsforum about a mirror you can buy, not sure for which projector. Do you have any idea??

    Digisocialist - Well I think I picked this projector up for a bargin, only 2 weeks old, with 12 hours on the clock. I was going to wait to see what the new D5 LCD chip looked like, next year, but I could never resist a bargin. I intended only to keep it for 1 year, so If I can not resolve this issue, I think I can live with a 6ft screen for 1 year.
    I am busy finishing off my loft conversion, so I have only had it running for about 20 mins, onto a white wall. Well! even that was impressive, very good blacks, did not see 1 rainbow at all. I was only using a old cheap dvd player at the time. I am waiting for the new Panasonic dv97s with HDMI, which will be released at the end of this month.
    Thanks,
    Barry.

    Baz,

    Sounds like you've done well there. I'll check out the Panasonic dv97s also as I too am in the market for a good dvd. :)

    Z1/2 has a funky wall mount available where PJ points directly up onto a mirror, use in rear projection system with CRT and LCD no hassle suggest you get your bathroom mirror and have a play
