The Green Slim series is the perfect choice for customers looking to upgrade their existing installed projectors. An industry-leading 2x optical zoom means that a Green Slim model will replace any installed projector seamlessly without having to change the ceiling brackets. This will help to keep budgets under control & disruption to a minimum. The Green Slim series offers brightness levels up to 3000 ANSI lumens more than enough for even a large bright classroom or meeting room – & a choice of XGA & WXGA resolution. All models have HDMI connectivity allowing users to present HD content for rich & vivid presentations. They are also light & portable so that they can be moved easily between rooms.
