The LFC works with projectors with most normal throw projectors and some short throw projectors (throw ratio 0.50-2.0).
Compatible projectors must have HDMI input and support 1080p input resolution. Projectors of any size and brightness can be used. As long as you can see the projected image well on an object, then Lightform will be able to perform a scan.
