44 Displaying and Adjusting the Image
2. Once the image is positioned where you want it, release the
buttons to lock the feet in position.
3. If necessary, you can level the picture or fine-tune the height by
turning the projector feet.
Raising the projector causes the image to distort or “keystone,” but
you can manually correct the shape as described in the next section.
Adjusting the Image Shape
In most cases, you can maintain a square or rectangular image by
placing the projector directly in front of the center of the screen and
using the Lens Shift (instead of tilting the projector upward) to adjust
the image height.
If this isn’t possible, use one of these methods to correct the image
shape:
■ If the image tapers inward on the right and left sides only, use
Keystone correction as described below.
■ If the image looks uneven on all sides, you can adjust its shape
using QuickCorner (see page 45).
You cannot use both Keystone correction and QuickCorner at the
same time.
Using Keystone Correction
To adjust your image when the right and left sides are uneven, do one
of the following:
■ Use the Keystone buttons on the projector’s control panel to
adjust the image shape.

note
The image will be slightly
shorter after adjusting. If it’s
important to maintain the
correct aspect ratio, use the
menu system to perform
Keystone correction, then
adjust the Height setting as
needed (see page 45).
