You’re comparing features on home entertainment projectors. What are the benefits of Vertical Lens Shift?
Achieving optimal image positioning, size and shape is critical to satisfying home entertainment viewing and is in large part dependent on the proper positioning of the projector and screen. The constrained spaces in many viewing environments, however, can make achieving this particularly challenging. Vertical lens shift is a tool that assists in properly aligning the projector’s lens with the projector screen, making it far easier to correctly mount or position a projector for optimal image quality. Projectors with vertical lens shift have the ability to move the projected image up and down to easily accommodate placement/installation at a variety of heights. Conversely, projectors without lens shift must be positioned with 100% accuracy to project an image with the proper shape and distribution across the screen.
Vertical lens shift enables users to:
Raise/lower the projected image without changing the angle relationship between the projector and the screen – eliminating the need to physically move the entire projector
Successfully install in spaces with limited vertical height, such as low 8-foot ceilings, whether ceiling mounted or placed on a rear shelf
Preserve head room in spaces that would otherwise require an extender pole for accurate positioning
Achieve correct image positioning without the need for compression and scaling (as used with Keystone correction), which can cause decreased resolution, artifacts, and often imperfect results
