Optoma UHZ45 4K UHD Laser Home Cinema Projector

Advanced Laser Technology

Optoma laser projectors use high-quality laser illumination to deliver exceptional brightness, colour performance and efficiency. With consistent brightness, instant on/off functionality and a long-lasting light source rated for up to 30,000 hours, laser technology provides reliable performance with minimal maintenance.

True 4K UHD Resolution

Experience sharper, more lifelike images with True 4K UHD resolution, delivering 8.3 million on-screen pixels for four times the detail of Full HD. Enjoy stunning clarity, richer colours and an immersive big-screen experience that brings movies, sports and games to life.

HDR10 & HLG Compatibility

Support for HDR10 and Hybrid Log Gamma (HLG) allows the projector to display greater detail, texture and depth. Bright highlights appear more natural, while darker scenes retain impressive shadow detail for a more realistic viewing experience.

Amazing Colour Performance

Enjoy vibrant, accurate colours across movies, television and gaming. Support for the Rec.709 colour gamut ensures faithful reproduction of cinematic colours, while the built-in Colour Management System allows precise adjustments to suit your viewing environment and personal preferences.

Dynamic Black Technology

Dynamic Black technology automatically adjusts light output according to the brightness of each frame, enhancing contrast and image depth. Bright scenes remain crisp and clear, while dark scenes reveal deeper blacks and improved shadow detail.

Immersive Big-Screen Entertainment

Create an impressive cinematic experience with projected images up to 300 inches, depending on room size, projection distance and lighting conditions. High brightness and vivid colours also make the projector suitable for watching movies, sports and television in rooms with some ambient lighting.

Smooth Motion & Enhanced Gaming

Enjoy ultra-smooth gameplay with support for refresh rates up to 240Hz at 1080p, reducing motion blur and ghosting during fast-paced action. Enhanced Gaming Mode optimises contrast and colour while reducing input lag for more responsive gaming performance.

True Cinematic 24p Playback

Support for 24fps playback preserves the original frame rate of cinematic content, allowing movies to be displayed as intended by the filmmaker for an authentic viewing experience.

Flexible HDMI Connectivity & eARC

Dual HDMI inputs make it easy to connect gaming consoles, Blu-ray players, computers and streaming devices. Enhanced Audio Return Channel (eARC) supports high-bandwidth audio transmission and uncompressed 5.1/7.1-channel audio pass-through to compatible sound systems, delivering high-quality movie soundtracks and music.

Integrated Speaker & USB Power

A built-in speaker provides convenient audio playback without requiring an external sound system. The USB-A power connection can also power compatible streaming devices such as Google Chromecast, making it easy to add smart entertainment functionality.

Flexible Installation & Image Adjustment

Four-corner correction, horizontal and vertical keystone adjustment, and advanced geometric correction allow precise image alignment, even when the projector is positioned at an angle or used with an uneven surface. Wall Colour Adjustment offers six presets to compensate for different wall colours, while 360° projection support provides additional installation flexibility.

Quick Start-Up & Quiet Operation

The laser light source reaches full brightness quickly and requires minimal cooling time when switched off. A pause projection function helps conserve energy, while operating noise below 30dB in ECO mode provides a quieter viewing experience.

Reliable Performance & Dust Protection

An IP6X-rated airtight optical engine provides excellent protection against dust, helping maintain brightness and long-term reliability. Designed to support 24/7 operation in standard orientation, the projector is suitable for extended use in demanding environments, subject to the manufacturer's operating recommendations and warranty conditions.
