Optoma Technology UHZ66 4000-Lumen UHD 4K Laser Projector

The Optoma UHZ66 is a laser projector designed for people who want theater-class 4K pictures at home without fussing over bulbs or room lighting. It delivers the full 8.3 million-pixel detail of Ultra HD, so movies, sporting events, and streamed shows look crisp and lifelike on screens that can fill an entire wall.

Brightness is a standout strength. With 4000 lumens, the image stays vivid even when the curtains are open or the lights are on, which makes it practical for living rooms, game rooms, and multipurpose spaces. HDR10 and HLG compatibility deepen contrast and pull out extra color detail, so shadows look more nuanced and highlights pop without washing out.

If gaming is part of the plan, the UHZ66 keeps pace. When set to 1080p at 240 Hz it can reach input lag as low as 4.4 ms, giving fast-twitch players the responsiveness they need for competitive play. Sports fans benefit too, because the same high refresh rate keeps on-screen action smooth and engaging.

Installation is straightforward. A 1.6× zoom and a standard throw lens give you room to adjust distance and screen size, so the projector works whether it is on a coffee table, ceiling-mounted, or placed on a rear shelf. Two HDMI 2.0 ports handle modern consoles, streaming sticks, and 4K Blu-ray players, while the built-in 15 W speaker provides clear audio when an external system is not available.

The laser light source is rated for up to 30,000 hours, which eliminates lamp replacements and reduces long-term cost. Optoma also built the chassis with recycled materials and engineered it for lower power draw, so owners get reliable performance with a lighter environmental footprint.
