The BENQ MH856UST is an optional interactive short throw projector suitable for classrooms and medium-sized meeting rooms. Teachers now can turn any space into an interactive whiteboard and get up to 4 students to collaborate simultaneously with Point Write pens or simply with fingers. This is an ultra-short throw projector so you will be able to create a large image at such a short distance from the screen. With a projection distance this close, you and your audience can move freely without worrying about obstructions between the projector and the screen! As a short throw projector the shadows will be eliminated and there will be no glare in the presenter’s eyes. The bright 3500 lumens means you can project throughout the day. The MH856UST features Full HD resolution giving you great clarity and is suitable for anything from basic data to Blu ray movies! There are two HDMI inputs and two VGA inputs so you can connect to multiple devices at one time. The USB input can be used for PC-free presentations. There are two 10W built in speakers which will be powerful enough for a medium sized audience. Overall, this is a great projector with some great features and connectivity and BENQ offer a 2 year warranty for peace of mind.
