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, superior colour across an extended lifespan.
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.
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.
Built-in media player
Share presentations directly from your projector without the need for an external device such as 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.
Integrated speaker
A built-in speaker offers excellent audio support and an easy setup without the need for costly external speakers
Direct power on
The projector will start up instantly when power is supplied to the unit. This eliminates the need to manually turn on the projector via the remote control or the keypad, ideal for use in rooms with a “master” power switch.
24p
Most movies are shot at 24 frames per second (fps). To preserve the purity of the original image, Optoma projectors can accept high definition sources at 24 fps to display movies exactly as the director intended.
Portrait projection
Ideal for digital signage applications you can rotate your projector 90 degrees to project a portrait image.
