Optoma UHZ66 4K laser projector: one-minute review
The Optoma UHZ66 is a rather staid update to the company’s projector lineup. It offers a bright 4K picture with solid contrast and the useful ability to drop down to 1080p and run at 240Hz for smooth gaming, but it’s not breaking the mold in any particular way. It may have good color, but it does not match competitors like the JMGO N1S Ultra.
HDR viewing on the Optoma UHZ66 leaves plenty to be desired, and its bland design isn’t offset by helpful utilitarian features you find on the best 4K projectors like vertical lens shift — something the BenQ X3100i includes. Factor in the lack of an onboard smart TV system for streaming, the bottom-of-the-barrel remote control, and the weak built-in speaker, and you get a system that’s not offering much value on top of the picture quality.
The Optoma UHZ66 really needed to do more to win our hearts. It’s got a good picture, but the picture is just about all it has, and even at its recent price of about $2,000, a good picture simply isn’t enough.
Optoma UHZ66 4K laser projector review: price and release date
- Release date: October 2023
- Price: $1,999 (around £1,637 / AU$3,230)
The Optoma UHZ66 has been on the market for a little while now, launching in late 2023. When it arrived, it had a retail price of $2,999 (about £2,935, AU$4,460), but street pricing has come down considerably since then. It’s readily available for $1,999 (around £1,637 / AU$3,230) at the time of writing and has wavered between about $1,800 and $2,300 for much of the past year. At $2,999, it would be an immediate pass for us, but at $1,999, it offers a slightly more competitive value.

Optoma UHZ66 4K laser projector review: design and features
- Bland design next to recent competitors
- Limited optical adjustments
- Requires additional home theater equipment
The Optoma UHZ66 is not one of those projectors that’s gotten a recent glow-up, like the JMGO N1S Ultimate or any from Xgimi. Instead, it’s your classic white plastic brick that would look just as at home in an office as it would in a home theater. The front of the projector is a flat piece of white plastic with a large lens protruding out of it. The sides are fully vented with grilles and the rear has an additional grille for even more airflow.
On the top of the Optoma UHZ66, you can find a handful of buttons that allow you to navigate the controls in case you misplace the remote control, which will be easy to do given how tiny it is. The top also includes a little slot with access to the zoom dial. That dial gives the UHZ66 an adjustable throw ratio, though no matter what you’re not getting a fairly long throw. The minimum is a 1.4:1 ratio. While optical zoom is useful, the Optoma UHZ66 unfortunately lacks vertical lens shift. I found placing it on a mantle at the back of a room too high to use it at all and also too low to use flipped upside-down. The most ideal setup is likely mounted to the ceiling with a long throw.
The Optoma UHZ66 sits on three small rubber feet allowing for some angle and tilt adjustments to help you align the projection with your wall. There are also mounting holes to set the UHZ66 up with a ceiling mount.
On the back of the projector, you’ll find a small selection of ports. You get two HDMI 2.0 inputs, including one with eARC, a USB port, a 3.5mm audio output, and RJ-45 and RS-232 ports. Given the projector only has a single speaker, an optical audio output would have also been good to see for more options and compatibility with different home theater setups given that HDMI eARC has a length limit and a 3.5mm port won’t carry a surround signal.
The remote included with the UHZ66 is not meant for much. It’s a flat little thing about the size of a few stacked credit cards. It has three columns of buttons with no way to physically discern between them, which makes navigating it a pain. It also lacks backlighting, so it’s hard to see in the dark conditions of a home theater. It does the job, but it has a long way to go to be user-friendly. It at least provides quick access to a few of the more important settings, such as input selection, picture mode, and keystone controls.
- Design and features score: 2.5/5
Optoma UHZ66 4K laser projector review: picture quality
- Bright, high-contrast 4K picture
- Low latency, especially in 240Hz mode
- System stutters during setting adjustments and signal switches
Let’s start with the good. The Optoma UHZ66 offers a respectably bright image and is easy to get exceptionally sharp with the focus dial. The 4K picture goes a long way at the sizes the projector is ready to display at. The contrast achieved by the projector is also commendable. Many projectors struggle with elevated black levels, but the UHZ66 can dim down quite low for blacks.
As bright as the UHZ66 may get, it doesn’t appear to want to get as bright as it’s rated for. Instead of hitting its rated 4,000 lumens, it comes closer to 2200 lumens, and even that requires a cooler color temperature setting to achieve. With the default warmer color, it falls toward 2100 lumens. I fiddled with a bunch of settings to see if I couldn’t figure out which might achieve Optoma’s lofty 4,000-lumen mark, but none quite got there.
Running the projector at its brightest settings requires opting for a cooler color temperature which makes the fans kick in. They can be fairly noisy if you’re close to them, though they’re not shrill or very loud in a larger room. Different settings also don’t require the fans to run as hard, such as the dimmer Reference mode.
The color output of the UHZ66 is impressive. ALPD laser projectors haven’t always had the most impressive color gamut coverage in my experience testing, but the UHZ66 blasts out impactful color for something like the opening credits of Cyberpunk: Edgerunners. One catch, though: it doesn’t seem to want to display its full color gamut when HDR is enabled. Everything turns rather mellow when HDR comes on. This is pretty much the opposite of what you’d expect from HDR content, so if you prefer a vibrant look, you’re better off setting your source devices to SDR output. Now, movies and TV don’t look bad in this condition, but they just lack some of the pop that they could have.
Trying to find ideal settings on the Optoma UHZ66 can be a real headache. The projector offers plenty of settings for tweaking the image, but navigating the menus is tedious thanks to the remote. And even just changing the volume on the Optoma UHZ66 is enough demand for the processor to actually cause the image to stutter. Switching picture modes or major settings can see blips where the projector goes out and comes back after a couple of seconds. And this happens not only when you’re changing settings yourself but also when you’re watching content and then back out to a menu.
A boon for gamers is the Optoma UHZ66’s ability to switch between 4K 60Hz and 1080p 240Hz modes. In its gaming mode, latency is minimal. It’s hard to detect input lag at 60Hz on the UHZ66 and it’s practically imperceptible at the 240Hz mode. DLP projection systems are rather fast as well, providing quick pixel response times to avoid ghosting.
The UHZ66’s single speaker sounds boxed in and rather awful. It’s nowhere near loud enough to match the kind of picture you can get from the UHZ66, and really shouldn’t be relied on for anything.
- Picture quality score: 3.5/5
Optoma UHZ66 4K laser projector review: value
- Limited utility for the price
- Calls for streaming devices and external speakers
The Optoma UHZ66 is just one piece of a home theater setup. While it does include a speaker, it’s poorly matched for the theater capabilities of the projector. The lack of an onboard smart TV system also means you’ll need a source device no matter what setup you go for. While there are certainly some nice extras, like the 240Hz mode, it’s still largely filling just one role. If it came with more flexibility, such as an adjustable lens offset or hardware keystone, it would offer more value. But as it is, it’s fairly expensive to leave so much out, especially when competing projectors don’t make such omissions.
| Attributes | Notes | Rating |
|---|---|---|
| Design and features | Vertical lens shift would have gone a long way to making the UHZ66 more flexible, and is it too much to ask for to get some automatic image correction from a projector at this price? | 2.5/5 |
| Picture quality performance | A bright, sharp, and reasonably colorful picture with solid gaming performance, but HDR capabilities leave something to be desired. | 3.5/5 |
| Value | The UHZ66 doesn’t have a mind-blowing enough picture to offset the many features it lacks. | 2.5/5 |

How I tested the Optoma UHZ66 4K laser projector
- Tested at home in multiple, real-world viewing conditions
- Presented the display with a variety of media and formats
- I have tested numerous projectors and displays over the last half-decade
I tested the Optoma UHZ66 at home, in real-world conditions. This saw it faced with ambient light coming in from numerous windows, in-room lighting, as well as ambient noise that both the projector and speaker systems had to overcome. The projector was tested both against a bare, white wall and an Akia Screens CineWhite screen. It was presented with streamed content, HDR and non-HDR, and PC gameplay.
My testing evaluates the projector’s performance with respect to its price and competition from other models I and colleagues at TechRadar have tested.
I have been testing projectors since 2021 and displays for even longer.
