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!
