Using the Projector
Adjusting the Image Shape
If the projector is raised in the front or the back, like this:
your projected image may not be square or rectangular; it may have a
“keystone” shape like one of the examples shown below.
To correct this, hold down the
Shift
button on the projector’s control
panel and press the top or bottom
Keystone
button until the corners
of the image are square.
After correction, your image will be slightly smaller.
The keystone adjustment remains in the projector’s memory, so if you
later change the position of the projector, you might need to adjust
the keystone setting as well.
If the image becomes distorted or blurry after you make a keystone
correction, try decreasing the
Sharpness
setting in the Video menu,
as described on page 30.
note
You can also correct keystone
distortion by displaying a test
pattern (as described in the
next section) or through the
projector’s Setting menu (see
page 35).
