I have a small 14’X12’ home theatre with a 120” screen and an Epson PoweLite
Cinema-Pro 1080UB projector. I’ve had this for a few years now, and I
recently had to take my projector down to clean the filter. My projector is
an overhead front mount. When I re-installed my projector the image is not
100% square to the screen frame. I would like to know the easiest, most
precise way to align the image to my screen with the Epson image shift and
zoom controls. I do also have a laser level as well. I have a throw distance
of 13.5’ which is just slightly more than the minimum for a 120” screen.
Thank-you for your assistance.

Hi Malcolm, there is no real easy way. I would make sure that before you start that you make sure that you are 100 percent level and inline with the screen.

Beyond that, it’s just a matter of throwing up a 16:9 image/frame that allows you properly zoom the image then align its horizontal and vertical shifts.

The big recommendation I would make is to try at all costs to avoid the keystone adjustments. Sometimes with keystone adjustments you’ll find that you fix one problem and create another.

It sounds like you have a pretty straight shoot so it shouldn’t take anymore than a few minutes to use your horizontal and vertical adjustments.
