The Optoma UHZ36 is a 4k UHD single-chip DLP home entertainment projector with a laser-phosphor light source. It has Optoma's PureEngine processing suite and a dedicated Filmmaker Mode for more hands-off, cinema-style playback. For setup, it uses a 1.3x manual zoom lens with manual focus, with an auto vertical keystone to help square the image. It keeps streaming simple by relying on external devices, but you do get two HDMI 2.0 inputs (one with ARC), a 15W built-in mono speaker, and basic integration options like RS232 and a 12V trigger.
Our Verdict
The Optoma UHZ36 is a decent pick for movies. It's bright enough for dim rooms and has good contrast, so you can just turn off the lights and have a good viewing experience. Unfortunately, the projector's image quality is poor out of the box, and the unit isn't colorful, which limits its impact. It's also very light on smart features, as it doesn't have a smart OS.
Bright projector, good enough for dim rooms.
Good contrast that performs especially well in brighter scenes.
Quite inaccurate out-of-the-box.
Decent color gamut overall, but struggles in the Rec. 2020 color space.
Barebones projector with no integrated smart OS.
Struggles in the darkest scenes, with a high black floor.
The Optoma UHZ36 is a poor choice for gaming due to its poor responsiveness, making it unusable for anything but the slowest turn-based titles. It also frame-skips at 120Hz, making it an only 60Hz projector. At least it looks decent in action due to its good brightness and contrast, even if it's not colorful.

The Optoma UHZ36 is bright. While you'll still want to turn off the lights or close the blinds, once you do so, the unit projects a bright image that holds up well even in rooms that aren't entirely blacked out. Unfortunately, it just can't project vibrant-looking colors, so the presentation looks a bit washed out.

Colors are washed out.
The Optoma UHZ36's contrast is good. It performs especially well in brighter scenes, with good separation between elements, even when compared to other projectors. Still, it stumbles in the darkest scenes, with visibly raised blacks.

Popular Projector Comparisons
The Optoma UHZ36 is a solid option for movies if you want a bright picture with decent contrast. However, it falls behind many newer lifestyle and home theater models in a few important areas: it isn't very accurate out of the box, it doesn't fully calibrate into a truly reference-level image, and its color looks comparatively washed out. It's also a poor pick for gaming, as input lag is very high, and it frame-skips at 1080p @ 120Hz, which defeats the point of its higher refresh support. For most people, the Hisense M2 Pro is the better buy thanks to its higher-performing contrast, much more accurate image, and significantly better gaming performance.

The Hisense M2 Pro is better than the Optoma UHZ36 in almost every way except for one: brightness. The Optoma is noticeably brighter, especially if you're using the unit in a room with ambient light. In a darker room, however, the Hisense stretches its legs, with better contrast, a much more vibrant image, and a more accurate image before and after calibration. For gamers, the Hisense is also far better, as it is very responsive at any resolution, and can game at up to 240Hz.
