True 4K UHD Resolution

Ultra HD 4K resolution delivers sharper, life-like images and richer colours – 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 colours

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

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 color performance, instant on/off, and an extraordinary life span of up to 30,000 hours.

Colour 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 of your projector for optimal precision.

ISF modes

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


Use the USB-A port to power external devices (5V/1.5A)

Full 3D

Display true 3D content from almost any 3D source, including 3D Blu-ray players, 3D broadcasting, and the latest generation game 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.

Enhanced gaming mode

Enhanced gaming mode optimizes your projector for maximum contrast and vivid colors to capture every detail. It also reduces input lag down to as little as {{ProjInput_Lag}}ms for lightning-fast response times.

Note: When this setting is enabled some settings will be disabled. Please refer to the user manual for more information.*

240Hz smooth motion

Enjoy ultra-smooth fluid motion and reduced ghosting. A high refresh rate makes it easier to keep track of the action, giving you a better chance of hitting your target earlier. Ideal for fast-action gaming.

With six options to chose from you can easily adjust for blackboard, light yellow, light green, light blue, pink and grey walls to get the most accurate color gamut.
