Epson BrightLink 575Wi 2700-Lumen WXGA Ultra-Short Throw 3LCD Projector

A beamsplitting prism sends red, blue, and green light through three monochrome LCDs to render a video image. The 3-chip 3LCD design features no moving parts in the imaging system, although there is still a cooling fan, and it is also free of the "rainbow effect" artifact sometimes perceived on color wheel-based projection systems.

A single lamp is estimated to last up to 10,000 hours in Eco mode. It provides 2700 lumens of color, white, and interactive brightness. Since this model supports equal color and white brightness, you can be sure both colors and grayscales are rendered in equal brightness.

This projector features a WXGA 1280 x 800 native resolution and a 16:10 native aspect ratio. This is considered a widescreen format, and comes very close to the 16:9 standard of HDTV. This format works well if you plan to show HD video, but can still be used for presentations. The projector supports 16:9 and 4:3 aspect ratios as well.

This projector features two USB ports. The type-A USB port supports PC-less presenting from a USB storage device, compatible digital camera, or mobile device with USB connectivity. It also lets you pass through data from connected USB devices – like a document camera – to the computer. The type-B USB port lets you connect the projector to a Windows or OS X computer to display audio and video (requires driver software installation; high-frame rate video may not be supported).

Multi-PC projection and the Moderator function allows up to 50 Windows/Mac/iOS/Android devices to connect over a network. You can display up to four different device screens from any of the 50 devices simultaneously and control which device screens to display. This feature makes it easy for teachers to encourage and control classroom collaboration. It's also a great way to compare students' work side-by-side.

The included Easy Interactive Tools 3.0 annotation software allows users to control projector settings over the network, record and save video from Epson document cameras, and save/reopen/edit annotation files. It allows access to archived curriculum as well. You can also program the interactive pen button to provide instant access to the most-used tools.

This collaborative learning software helps teachers create high-impact lessons – anytime, anywhere. It offers a multitude of digital resources as well as customizable content. Each BrightLink projector that comes with this optional software includes a four-seat user license, which is available for Windows and Mac.

When using the included Epson EasyMP software with a networked BrightLink projector, teachers are no longer tied down by cables. Educators can wirelessly display and interact with content as they move about the classroom with their laptop, experiencing true interactive freedom.

ActivInspire software enables teachers to engage their students in interactive activities that are designed to grab their attention. Each BrightLink projector with this optional software includes a full version and a five-seat user license, which is available for Windows and Mac operating systems.

You can also use the projector remote to control your connected MHL-enabled mobile devices and you can charge your MHL-enabled mobile devices when they're plugged into the projector's MHL input.

Auto calibration helps you get the projector up and running as fast as possible by calibrating the display and image settings based on your projection environment and setup.

Quick Corner allows you to move any of the four corners of an image independently. This will let you adjust each corner just the right amount to ensure a perfectly rectangular picture.

Quick, convenient control with Instant Off means no cool-down time is required - you just shut down the projector whenever you're finished with your presentation or viewing experience.

Copy menu settings for multiple projector installations and save on installation time. You can copy settings via a USB flash drive, USB cable or LAN.
