3M are always bringing out new projectors that have something different from the rest, that is what they do best, they develop new technologies. They don't have a huge range of projectors but  they tend to focus on a certain feature and in this case it is the fast growing short throw projectors and they are for fixed use only .

Bring portable audio and video performance to the smallest office, classroom or living room with our Digital Media Systems (DMS)700 Series projectors. Features include Vikuiti™ Super Close Projection for a 1.5m diagonal screen image from 70cm away, Hollywood Quality Video (HQV™) displayed on almost any surface from just 89" away.

Digital Media System (DMS) 800 Series combines projection, sound, and an interactive whiteboard into a single wall mounted solution, to provide the core tools needed to get your audience watching and participating at the same time, whatever your situation
