This can be purchased from your computer or electronics dealer or from EPSON. (See page 4.) (If you have to raise the front of the projector, you can use the projector's keystone correction to eliminate distortion caused by tilting the projector upward.

If you'll be projecting from overhead, you can get the best-looking picture by mounting the projector parallel to the ceiling, with its lens at least as high as the middle of the screen, but no higher than the top of the screen.

Setting Up the Projector
When projecting from a table, the ideal arrangement is to set the
projector flat on its surface. This way, you can use the lens shift knob
(instead of raising the projector’s feet) to position the image on-screen.
This delivers the best-looking picture.
You won’t need to tilt the projector upward as long as you position it
so that its lens is at least as high as the bottom of the screen, but no
higher than the middle of the screen, as shown:
(If you have to raise the front of the projector, you can use the
projector’s keystone correction to eliminate distortion caused by
tilting the projector upward. But you’ll still get a better picture if you
can leave the projector flat on the table, without extending its feet.)
If you’ll be projecting from overhead, you can get the best-looking
picture by mounting the projector parallel to the ceiling, with its lens
at least as high as the middle of the screen, but no higher than the top
of the screen. Then use the height adjustment knob to position the
image on-screen. You’ll also need to select ceiling projection in the
projector’s Advanced menu. See page 71.
