Keystone
If the projector is ceiling-mounted and the screen is lower than the projector, you
may need to tilt the projector by adjusting the ceiling mount. If you do so:
•
the top and bottom borders of the image will be unequal in length
•
the sides of the image will be inclined
If the tilt is not excessive, you can use the Keystone function of the projector to
correct the image shape. (See “V Keystone” on page 41)
Note:
Keystone correction may cause artifacts in the image and may not be available
when displaying specific 3D content.
