True 4K UHD Resolution

Ultra HD 4K resolution delivers sharper, life-like images and richer colors - allowing you to sit closer to the screen and enjoy a more immersive experience.


Our DLP projectors provide CTA (Consumer Technology Association) approved True 4K UHD resolution, capable of projecting 8.3 million on screen pixels. That's four times more detail than Full HD and twice as many from competing technology, which only delivers 4.1 million pixels.



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 and the extra detail creates a greater sense of depth.



Amazing color

Watch your movies, TV shows and play games with stunning colors in any environment. Optoma projectors provide reliable performance suitable for any content and environment. Our home projectors are capable of reproducing the Rec.709 color gamut, the international HDTV standard to guarantee accurate reproduction of cinematic color exactly as the director intended. Or more saturated colors for a punchy looking image, great for gaming and animated movies.




Using sophisticated frame-interpolation technology, advanced motion control processing eliminates motion blurring or image judder, even in high-speed action sequences.



Color Management System (CMS)

Display accurate lifelike colors to best match your viewing environment. This unique feature provides you with the flexibility to fine-tune the color settings for optimal precision.



ISF modes

This feature allows you to save your calibrated day and night mode settings for the highest possible viewing experience.



Full 3D

Optoma projectors can display true 3D content from almost any 3D source, including 3D Blu-ray players, 3D broadcasting and the latest generation games consoles.



Dual HDMI inputs

Play games, stream videos and share photos on the big screen in the comfort of your own home. With dual HDMI inputs, you can easily connect to your games 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 like the Google Chromecast™, Amazon Fire TV, Apple TV™ or Roku® stick.



Built in media player

Watch movies directly from your projector without the need of a laptop or PC by using the built-in media player. Simply copy your files to a USB stick and watch them on the big screen.
