True 4K UHD resolution

Ultra HD 4K resolution delivers sharper, more lifelike images and richer colours - so you can sit closer to the screen and enjoy a more immersive experience.

Our DLP projectors offer CTA (Consumer Technology Association) approved True 4K UHD resolution and can project 8.3 million pixels onto the screen. That's four times the detail of Full HD and twice that of competing technologies that deliver just 4.1 million pixels.

HDR and HLG compatible

Supports both HDR10 and Hybrid Log Gamma (HLG) HDR content. With this Optoma projector, you can see much more detail and texture. Objects look more solid and lifelike and the extra detail creates a greater sense of depth.

Lights on Film off!

This versatile projector combines high brightness and vivid colours for lifelike images in any environment. Leave a lasting impression with bigger and bolder presentations any time of day.

Dual HDMI inputs

Play games, stream videos and share photos on the big screen in the comfort of your own home. Dual HDMI inputs let you easily connect your game console, set-top box, laptop, PC, Blu-ray player or media streamer with a single cable. You can even turn it into a smart projector by connecting an HDMI dongle such as Google Chromecast™, Amazon Fire TV, Apple TV™ or Roku® stick.
