    Hi all,

    I've been doing a bit of research concerning a new PJ, and have kind of settled on either the Sharp XV-90 or the Pan AE300.

    However, one thing eludes me. I know these projectors all keystone the image to remove the trapezoid effect for ceiling mounts, etc. I have to problem where my screen is facing a door, so the projector will have to be situated to the right of the door (i.e. not directly facing the screen). Do these projectors handle this situation, or will I have to rethink the room?

    Many thanks...

    Will let others comment on the PJs you mention, but the HS10 has both vertical & horizontal correction (digital).

    IIRC, the Z1 has both forms of correction (optical). Digital correction does effect PQ - optical lens shift would be a better option IMO.

    Why not block up the door & thus avoid any correction?

    I would :D

    AE300 also has horizontal & vertical keystone correction.

    Got to agree with Kramer though, Keystone correction has a detrimental effect on PQ. Especially when viewing text, like on a PC desktop.

    If you've no choice with the room layout then I guess it would have to be one of the compromises that you have to live with.
    :(

    Good Luck

    Hmmm,

    I thought there would be downsides to keystoning

    Ho hum - my only other option is bringing the projector to about 9' from the screen, but I figured this would be too close.

    Hi Spanx,

    My DIYprojector is 8' away from the screen, and put's out a screen size of 85" diag.

    And the quality is great via the htpc....

    Cheers

    Of course, as my wife cunningly pointed out, there is actually a projector sized space ABOVE the door. Damn her and her common-sense.
