Lights on viewing

This versatile projector combines high brightness and vivid colours for vibrant, true-to-life visuals in a wide range of environments. Make a lasting impression with bigger and bolder presentations any time of day.

*With no direct sunlight or lights directed at the screen.

Laser technology

Optoma laser projectors use high-quality lasers to create the projected image. In many situations, the perceived brightness from laser illumination projectors can be twice that of an equivalent lamp-based model. They also deliver increased efficiency to maintain consistent brightness, superior colour performance, instant on/off and an extraordinary life span of up to 30,000 hours.

DuraCore

Industry-leading lifetime is achieved using Optoma’s DuraCore technology, implementing advanced laser diode cooling techniques and an innovative dust-resistant design.

Short Throw

With a short throw lens, you can project an impressive 100" image from just over a metre away. This allows you to place the projector closer to the wall, reducing shadows so you can present with ease.

HDR and HLG compatible

Capable of receiving and displaying both HDR10 and Hybrid Log Gamma (HLG) HDR content. This Optoma projector allows you to see far more detail and texture. Objects look more solid and lifelike, while the extra detail creates a greater sense of depth.

Amazing colour
