Boardroom and classroom presentations get a boost in quality and versatility with the PowerLite 1850W. Adapting to almost any layout, this projector provides the ultimate in setup flexibility. Place the projector anywhere in the room and get perfectly rectangular images using the horizontal keystone correction slider bar. Impressive widescreen (WXGA) resolution and 3700 lumens of colour and white light output ensure sharp, larger-than-life images, while a 1.6x optical zoom makes it easy to display larger images from shorter distances, saving valuable space. Advanced connectivity offers even more flexibility with HDMI inputs for both video and audio, 3-in-1 USB Plug 'n Play connectivity and PC-free presentations.
