4K UHD Resolution

With over eight million pixels, Ultra HD 4K resolution brings four times more detail than Full HD, to deliver sharper, life-like images and richer colours - allowing you to sit closer to the screen and enjoy a more immersive experience.

HDR compatible

Capable of receiving and displaying HDR meta data, Optoma HDR compatible projectors allow you to see far more detail and texture. Objects look more solid and life like and the extra detail creates a greater sense of depth. It’s like looking through a window.

Amazing colours

Watch your movies, 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.

Vertical Lens Shift

Simplify installation with vertical lens shift, which provides a wider range of projector placement possibilities. This makes it easier to position the projector in your room and enables a wider range of screen size options.


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


This technology ensures all the information contained in an image is faithfully reproduced on the screen giving a stunning crystal clear, pin-sharp picture.


This mode makes it possible for the projector to reproduce more detailed shades of colour; to provide vivid, balanced colour for vibrant, natural looking images.

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.

Colour Management System (CMS)

Display accurate lifelike colours to best match your viewing environment. This unique feature provides you with the flexibility to fine-tune the colour 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.


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.


Use the USB-A port to power an HDMI dongle, such as Google Chromecast.

Integrated speaker

Complete your home entertainment experience with the convenience of a powerful built-in speaker for exceptional sound quality and an easy set up without the need for costly external speakers.
