• Instant setup: get a clear, aligned picture in seconds with auto keystone and focus
• Compact & lightweight: weighs less than one pound and fits anywhere

• LED technology: Built with LED technology, this projector uses high-quality individual red, green and blue LEDs to create the projected image. In many situations, the perceived brightness from LED illumination can be twice that of an equivalent lamp-based model. This smart technology also delivers increased efficiency to maintain consistent brightness and superior color across an extended lifespan.

• Vivid HD Resolution for Crisp Visuals: Enjoy bright, sharp images with WXGA resolution (1280x800) and a large projection size ranging from 50” to 100” for immersive viewing at home, work, or on the go.

• Auto keystone: Auto keystone automatically adjusts the trapezoid effect to create a perfectly aligned image when a projector is off-axis, or the desired projection surface is not perfectly flat. (Auto keystone only adjusts the image in the vertical plane.)

• Native office viewer: Give presentations directly from your projector without the need of a laptop or PC using the built-in office viewer. Simply copy your Word, Excel, PowerPoint, PDF or JPEG files to a USB stick, SD card or microSD (depending on the projector input) and display them on the big screen. (See the Specifications tab for a full list of inputs.)

• Built-in media player: Give presentations directly from your projector without the need of a laptop or PC using the built-in media player. Simply copy your documents, images and videos to a USB stick / SD card / microSD card (depending on the projector input) and display them on the big screen.

• Seamless Wireless Sharing with Display Share: Effortlessly share content using the Display Share App—compatible with Android, iOS, Windows, and macOS—for screen mirroring, casting, and smart remote control without a PC (Wi-Fi dongle required). Ideal for presentations, collaboration, and digital signage applications.

• Optoma file manager: Optoma file manager allows users to manage files and folders. Users can also access cloud drives and browse, create, rename, copy, move and delete files.

• Direct power off: Power off your projector immediately or directly at the main power source. This means you don’t have to wait for the projector to cool down before turning it off.
