The Epson PowerLite 77c delivers presentations that are sure to impress with 2200 lumens, XGA resolution and high-aperture Epson 3LCD technology - all from a 6 lb projector built to go wherever business takes you. The smart choice for any office, it even includes an energy-efficient E-TORL lamp. Get right to it with Instant On (5-second startup) and auto keystone adjustments. Then, take control of your presentation with the convenient A/V Mute Slide. Just slide it over to instantly shut off images and sound. That way, your audience can focus on you. After you've completed your presentation, shut down quickly using the Instant Off function, and head off to that next important meeting.
