    Hi,

    I have a choice of ceiling mounting my Z2 at 14 or 15 foot from the screen. This will result in a diagonal screen size of 107" or 114". The seating position is roughly 12-13 foot from the screen. Will this result in a poorer image quality? I am concerned about VB from this distance. I cannot mount the PJ any closer than 14 foot. Is there also a way on the Z2 to reduce the image size below 107", such as a screen setting?

    I've been looking at the Da-Lite MODEL B 106 inch diagonal (52X92 Nominal Picture Area) Matte White screen. Is this a good starter screen?

    Thanks!

    Al, if you are going to get vertical banding, you'll get it from any distance. Why worry about problems before you even get the projector. If you're worried about VB buy a different projector. You can make the image larger or smaller with the zoom lens. Did you check the "Projector Calculator" at Projectorcentral.com or Sanyo to determine the image size at your throw distance?
    That screen you mentioned is a pull-down screen, right? The problem will be it WILL develop wrinkles, and they cannot be removed. You should make your own screen. I made my 106" diagonal screen for $40.00, using 1X3 pine and Blackout cloth from Joann Fabrics. It is my first screen and I'm very happy with it.

    Jim, thanks for your reply. I tested last night and found that a 100" image was fine (apart from pixelation -see other thread).

    One thing I noticed was that the square area that is projected onto the wall is very light which means that the borders that surround a widescreen image are very high in contrast. I tried to turn down the iris, the gamma etc. to get rid of these light borders but no luck.

    Is this expected to go away when projected onto a decent screen?

    Thanks.
