Lens shift projectors

Lens shift

— the projector has a movable lens that can move at least vertically, and in the most advanced models — also horizontally. This function allows you to adjust the location of the "picture" relative to the screen — most often it is about setting the image exactly in the centre. Using a moving lens for this is much easier than moving the projector or screen itself. Therefore, such models can be very useful for those who are not sure that the installation location will optimally match the screen location.
