    My projector is 8.5 feet away from my screen and the lens is 7" above the centerline of a 27" tall screen. Is it better for me to angle the projector downward a little or to use the lens shift feature to move the image down...or a little of both?

    Thanks,

    Craig

    If the lens shift is optical, that's okay. If it's a "digital keystone correction," avoid it like the plague.

    Do you really mean 27" high screen from 8.5' throw?

    Yes, I really meant 27" high. It's 48" wide. (16:9)

    The lens shift is optical (Panasonic AE900U)

    Use the lens shift....that is why it is offered on that projector. Keystone essentialy changes the overall picture by removing pixels. However if you have to use a little keystone that will not be a big deal and probably not detectable.

    To get the most out of your projector, it is best to install the projector close to the height of the top edge of the screen.

    This allows the light to bounce off the screen and down towards the viewer, providing a brighter picture.
