Verdict
The Optoma UHZ66 suits gamers and movie fans who want a sharp, bright picture, but it has few ports and no smart TV platform.

Third-party reviews

What customers like about Optoma UHZ66

  • 4000 ANSI lumens give a bright picture on a large wall.
  • A 303 inch maximum picture fills a big wall.
  • The 240 Hz refresh rate keeps fast motion smooth.
  • A 16.9 ms input lag suits fast games.
  • The laser light source is rated for 30000 hours.
  • Pixel shifting adds sharpness to 4K content.

What customers don't like about Optoma UHZ66

  • Focus is fixed, so sharpness depends on where you place the projector.
  • There is no Wi-Fi or smart TV function, so streaming needs another device.
  • The built-in speaker is only 15 W, so most buyers add sound.
  • The 1.3 m minimum throw distance needs room behind the projector.

Verdict

Dark room, big wall: that is where the Optoma UHZ66 does its job well. It is a 4K laser projector with 4000 ANSI lumens, and it can throw a picture up to 303 inch wide. The 240 Hz refresh rate and 16.9 ms input lag keep fast games smooth and quick to respond. Pixel shifting adds sharpness to 4K content, and the laser light source is rated for 30000 hours, so the light will last for years. It can also be mounted on a ceiling, which keeps it out of the way. The trade-off is focus: it is fixed, so you set sharpness by moving the projector, with no manual focus. It suits a gamer or film fan with a dark room, a plain wall and a separate speaker.
