The Viewsonic PS501X is a high brightness XGA short throw projector for education. With the ability to project 100″ images from a distance of 124cm from any projection surface the projector is flexible enough to fit any classroom design and keeps the presenter clear of the projection beam. For times when lights in the classroom must be kept on a high brightness of 3500 ANSI Lumens ensures that images remain clear and detailed. Fit For Classrooms of All Sizes 0.61 short throw projection gives you room to work with when positioning the projector. With the flexibility to be placed within inches of a screen users will be able to project big images in any space while also keeping presenters clear of the projection beam and avoid image shadows. Bright Images in Any Environment Packed with 3500 lumens of brightness and a 22000 1 high contrast ratio this projector is guaranteed to produce bright images in any setting even in spaces with high ambient lighting. Best in Class Colour Accuracy ViewSonic’s proprietary SuperColor™ Technology offers a wider color range ensuring users enjoy true-to-life color projection in both bright and dark environments. Fantastic 3D Viewing The HDMI port allows users to display 3D imagery directly from 3D Blu-Ray players and connect to HDMI-enabled devices such as laptops tablets and media players. Interactive module compatible With the optional interactive package (PJ-vTouch-10S) this projector becomes an interactive tool that transforms any surface into an interactive whiteboard. With the multi-touch capability users can simultaneously annotate write or draw on the projected image to interact with the content and share ideas. Integrated Power Source A built in USB power output (5V/1.5A) can be used to supply power to HDMI dongles eliminating the need for separate power adapters for connected dongles. Extended Lifespan When the Power Saving setting is turned on and no signal input is detected the projector will automatically switch into Eco Mode and SuperEco Mode. Reminder for Time Management The Presenter Timer is an embedded on-screen timer and a great time management tool for helping presentations run on schedule. Sleep Timer The sleep timer allows the projector to automatically power down after no signal has been detected. An easy way to save energy and extend the projector’s lifespan.
