Also to know is, do I need lens shift on my projector?
Vertical lens shift, which moves the projectedimage up and down, allows the projector to be placed atdifferent heights and still properly light up your screen. If youplan to install your projector on a rear shelf so that theprojector is about the same height as the screen, you onlyneed a modest lens shift range.
How does projector keystone work?
Keystone correction is performed digitally beforethe image passes through the lens, and is accessed by theprojector's on-screen menu function, or via a dedicatedcontrol button on the projector or remote control. Thismeans you may still have image shape distortion along the edges ofthe projected image.
