Eco-friendly compact high brightness 4K UHD laser projector
The UHZ35ST is one of Optoma’s most compact and hassle-free 4K UHD DuraCore laser projectors to date. Designed for maintenance-free continuous operation, this 3 500-lumen projector delivers powerful image performance with flexible installation features and extensive connectivity options in a sleek, compact form factor, up to 34% smaller than previous Optoma models.¹

To support Optoma’s commitment to sustainability, the UHZ35ST cuts power consumption by up to 45% compared to Optoma’s lamp-based projectors.² Energy-saving DuraCore laser technology ensures a long product lifespan of up to 30,000 hours without the need for additional lamps, requires minimal maintenance, and is mercury-free, further lowering its carbon footprint.

An added benefit, the UHZ35ST features an external power supply offering more reliability, portability and energy efficiency.

Designed with the environment in mind, the eco-friendly chassis design is made with up to 50% PCR (Post-Consumer Recycled) plastics and the packaging contains up to 97% recyclable materials.³ In addition, the compact product and packaging size of the Optoma UHZ35ST projector allows 2x more products carried per container, resulting in more efficient logistics to help further reduce carbon emissions.¹

The UHZ35ST offers superior contrast, accurate true-to-life colour reproduction for movie lovers and delivers bright 3500 lumens so sports fans can enjoy live action with the lights on. It also reduces input lag down to as little as 4.4ms (1080p 240Hz) – perfect for a competitive gaming advantage.

Big screen entertainment
Create and view images far larger than any TV with a projector. You can create a massive up to 300” image*. Perfect for recreating the immersive cinema experience in the comfort of your own home.

Lights on viewing
This all-round home entertainment projector combines high brightness and vivid colours for vibrant, true-to-life visuals in well-lit environments* – ideal for watching TV shows, sports and movies or gaming with family or friends any time of day


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 colour
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.

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.

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.

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

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.

Enhanced gaming mode
Enhanced gaming mode optimises your projector for maximum contrast and vivid colours to capture every detail. It also reduces input lag down to as little as 4.2ms for lightning-fast response times.

240 Hz 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.

Get right inside the action with the most immersive experience possible – a huge screen up to 300in.* Far larger than the average TV, split-screen multiplayer games are more enjoyable to play on the big screen.

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.

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.

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

Geometric correction
Adjust individual points to get the image perfectly square using the advanced built-in geometric correction tool. Ideal if you are not using a screen and have an uneven wall you want to project onto.

Wall colour adjustment
Don’t have a white wall or a projector screen? No problem! With the “Wall Colour” setting, you can alter the projected image based on the colour of your wall. 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 colour gamut.
