The Optoma UHZ55 is the latest addition to the 2024 line of 4K home entertainment projectors. At a $2,499 EST (Optoma Estimated Street Price), Optoma is positioning the UHZ55 as a high-quality home theater and high-performance gaming projector.
The UHZ55 uses a DLP 0.47-inch Digital Light Processing (DLP) chip with XPR shifting technology and a 1.3x zoom lens to project a 4K UHD (3840 x 2160) image as large as 300 inches diagonally onscreen. Its laser light source can deliver 3,000 ANSI lumens of brightness, a dynamic contrast of 2,500,000:1, and all with up to 30,000 hours of extended life.
Regarding gaming, the UHZ55 provides players with a big-screen gaming experience made up of 1.07 billion colors, HDR compatibility, and blazing fast speeds as low as 3.2 ms at 1,080p 240 Hz and 16.2 ms at 4K 60 Hz. That makes the gameplay smooth, and the delay between pressing the trigger and the action on the screen is almost indiscernible.

Optoma has been in the projection industry since 2004 and is today a leading large-display brand and, specifically, the world's number one 4K UHD projector brand.
The Optoma UHZ55 laser projector follows the company's popular 2022 model, the UHZ50. Except for the chassis's black color, the UHZ55 appears identical to the UHZ50 in both design and features. Those following consumer electronics will likely be relatively familiar with this practice. It is not unusual. However, looks can sometimes be deceiving. Even though the UHZ55 seems to have features and specs identical to the UHZ50, Optoma has decided to price the UHZ55 $300 less than the previous model without removing any features or reducing performance, at least on paper. It remains to be seen if Optoma is improving the UHZ55's performance.
In this review, I will briefly overview the UHZ55's key features and benefits and then discuss the projector hardware. In the Performance section, I will also discuss the results of my testing and discover any changes from the UHZ50 that Optoma may have made.
Let's get started.
The UHZ55 uses a DuraCore single blue laser plus phosphor light source with a six-segment color wheel (RGBRGB). Optoma rates the max brightness of the UHZ55's laser as 3,000 lumens, identical to the 2022 model. The UHZ55 can display the entire Rec.709 color gamut and 85% of the DCI-P3 color space. DCI-PE is the primary color space used to standardize colors in the film industry and for digital theatrical motion picture distribution. Designed for ultra HD and HDR, it typically displays pleasantly saturated and vibrant colors. The incredibly bright light source used on the UHZ55 is built to last up to 20,000 hours in NORMAL light output mode and 30,000 hours in ECO mode.
The uniform brightness of the projector's DuraCore laser light source creates a uniform image with no visible hot spots and allows the UHZ55 to display HDR-encoded content. Therefore, projected images are more color-accurate and offer increased detail in darker areas. This improved performance enables movies to be seen as the creators intended and enhances the gaming experience when playing HDR-encoded console games.
One key benefit of the UHZ55's 3,000-lumen light source is the viewing experience that frees you from the confines of a darkened room to enjoy movies, games, or presentations in spaces or situations where ambient light is unavoidable. This is called lights-on viewing. The ability to achieve lights-on viewing depends on a projector's brightness (lumens) and contrast ratio.
The UHZ55 features a 2,500,000:1 dynamic contrast ratio, which allows the projector to preserve image depth and detail even in well-lit environments. Projectors lacking sufficient brightness or contrast may produce washed-out images in the presence of ambient light, reducing the color and clarity of the projected image. Using an ambient light-rejecting (ALR) screen can enhance image quality even more by absorbing ambient light and reflecting the projector's light back to the viewer.
The UHZ55 is not a smart projector in the sense of an Apple TV or Google TV device, but it does come with access to the Optoma application store. Users can download and install various streaming apps from companies like Hulu and Netflix. That's where the smart media integration ends because that experience is nothing like Android or iOS. I would have preferred that Optoma provide a fully integrated Android TV solution like many other brands of projectors, especially at this unit's price point.
The UHZ55 comes with Optoma's INFOWALL and WALL COLOR ADJUSTMENT modes and their Great Masters' collection functionality, like the CinemaX projectors that I recently reviewed. InfoWall lets you display custom wallpapers and information such as recent news, date, time, and weather onscreen when the projector is not being used to watch movies. Optoma also includes its Great Masters app, which lets you display famous artwork.
Like previous Optoma models, the company even considers customers who don't have or won't always use a projection screen with their WALL COLOR SETTING feature. This technology works great even if you don't have a white wall. As the name implies, Optoma's Wall Color setting lets you alter the projected image based on the color of your wall. With six options to choose from, you can easily adjust for projecting on various colored walls, including blackboard, light yellow, light green, light blue, pink, and grey, to get more accurate color reproduction despite not projecting onto a white surface.
The UHZ55 offers a robust built-in media player that allows you to play content like movies, audio files, and even presentation files directly from the projector without needing an external device such as a laptop or PC. All you have to do is copy your documents, images, and videos to a USB stick, and you can play, display, or listen to them on the UHZ55's big screen. Like 3D, this feature seems to be disappearing from many projector brands, but I'm glad to see that Optoma is keeping it.
Another noteworthy feature is that the UHZ55 is WiSA-certified to deliver wireless audio excellence and work seamlessly with other WiSA-certified products. WiSA technologies enable ultra-high-quality audio to be transmitted and received wirelessly, with perfect synchronization and no perceivable latency.
The Optoma UHZ55 is a pretty typical home theater projector design. Basically, it's a square box with a lens on the front, controls on the top and side, and inputs on the rear. This projector's design and layout are identical to the UHZ50, except that this new model is black, which I think is great because it should reflect a smaller amount of ambient light back at your screen than the creamy white UHZ50. Big thumbs up, Optoma.
Like most Optoma projectors, the design of the UHZ55 is neutral in the regard that the projector is not going to draw huge attention to itself, but it is attractive.
The projector measures (W x D x H) 13.26 x 10.43 x 4.69 inches (337 x 265 x 119.3 mm) and weighs 11.02 lbs (5 kg).
The Optoma UHZ55 has an eight-button control panel with a simple configuration on top of the projector. There are LED lights for light source status, projector temperature, and projector power status. There are individual buttons for Power On and Power Off. One button launches the projector Menu, and four directional keys do double duty for Keystone Correction and Source selection.
I have to say that I prefer the more traditional control panel arrangement where navigation controls surround an option select button. I find that style is easier to use by touch.
All the inputs and connections are located on the rear of the UHZ55. The projector comes with three (3) HDMI 2.0 inputs. You should use #1 if you plan to leverage the projector eARC functionality, #2 should be for gaming, and input #3 is best for taking advantage of Optoma's PureMotion (motion smoothing technology). Since this is a common industry practice, I understand limiting eARC to one HDMI input, but tying gaming and motion interpolation to a specific input could make dual console gaming setups inconvenient. The same applies to motion smoothing if you have multiple sources for media, and who doesn't?
I'm guessing that Optoma assigned specific technology like PureMotion to one input because PureMotion technology can't be turned completely off. To address this, Optoma fixed PureMotion to HDMI input #3 so users can choose motion smoothing or not. I think Optoma needs to fix this on future models because most of us have multiple video playback devices and, in many cases, more than one video game console.
The UHZ55 has three USB Type-A inputs, with one dedicated to Service and Power functionality. This is great if you want to add an external HDMI media stick like a Google TV or Amazon FireStick that requires 5V power in addition to the HMDI input they are plugged into. All the USB inputs are only USB 2.0. Optoma has wisely kept an RJ45 network connector and an RS232 port for control. Finally, the UHZ55 offers S/DIF and 3.5 mm Audio Out ports, a 12V trigger, and a 3D Sync connection.
Like the Optoma UHZ50 projector, the remote is smaller in the style of many HDMI-based smart media sticks. Personally, I prefer the older style remote with its far more direct shortcut buttons. It just feels more comfortable in my hand because it is taller, wider, and about an inch thicker than the new remote control for the UHZ55.
Since this smaller remote is smaller, all the writing on it is smaller. However, I like that Optoma has turned down the backlight from the slightly larger older remote, which was glaringly bright when used in the dark. Reaction times from pressing the button to an action happening are noticeably slower on this remote than on other projectors I have reviewed.
Overall, the remote control experience is frustrating. During my review, I sat behind the projector, and due to the poor placement of the IR sensor, I had to hold the remote above my head to get a solid connection. This became quickly tiring. The menu system was sometimes slow to respond or hesitant as if the menu navigation processor was overwhelmed. Also, the image would get choppy whenever I pressed a button while the menu was onscreen. I'm not really critical of this experience since it happens when the menu is onscreen, but I point it out as further evidence that this projector's menu controller is underpowered.
The Optoma UHZ55 has a 1.3x manual zoom lens with a focal length of
12.81 mm ~ 16.74 mm. The projector has a vertical lens shift of +10% with a native offset of 105%. Focus is adjusted using a ring, a slider located on the top front of the projector adjusts a zoom range of 1.3x, and the vertical lens shift is controlled by a wheel directly behind the zoom control.
The UHZ55 has a 1.21:1 ~ 1.59:1 throw ratio and has a manufacturer's recommended projection distance of 47.24" to 318.9" inches diagonally on a 16:9 screen.
The UHZ55 includes powerful auto-alignment tools (Four Corner, Zoom, Aspect Ratio, Image Shift, and 3x3 Warp). These tools are convenient, but I recommend that users spend some extra time manually aligning the projector position to the screen before choosing digital adjustments because they negatively affect overall picture quality.
The menus on the UHZ55 follow Optoma's traditional design, characterized by simplicity and logical navigation that provide access to all projector functions. This projector features two menu systems: the Core and Home menus. The Home interface is more visual and resembles the design of Android TV. However, it is disappointing that Optoma has not integrated all of the projector's functionality into it. Instead, only a limited number of controls are available in the Home menu, leaving most of the functionality in the Core menu.
The UHZ55 supports a limited number of native applications available in the Optoma marketplace. Only two major streaming service applications are available: Prime Video and Netflix.
I strongly recommend using an external device like a Google TV, Firestick, or Apple TV to get the complete streaming media and application experience.
The UHZ55 uses a single blue laser diode and a six-segment color wheel to generate the three primary red, green, and blue colors needed to display moves, television, and game content accurately onscreen. Optoma does post a color range in their materials of 85% of the DCI-P3 color space. The UHZ55 can produce a pretty impressive visual color palette, allowing images to be dynamic and saturated. Overall, I found the CINEMA color preset mode the best display movies and TV shows.
This projector's image is consistent with other Optoma projectors' blue laser phosphor (BLP) projectors, which were reviewed on our website. Most recently, I reviewed the ultra-short throw CinemaX D2 Smart and the CinemaX P2. The UHZ55's colors are good, Most of the projectors preset picture modes are warm with moderate red hues with the exception of the brightest modes of the projector leaning more blue green, which is typical.
The UHZ55 produced vivid and pleasantly saturated colors in a wide range of content that I projected. Except in the modes designed to support bright environments, it displayed vibrant reds and blues without the greens becoming too harsh.
Out-of-the-box (OOTB) HDR preset picture mode colors are slightly more saturated than SDR, but the difference is not overly dramatic. The projector's 3,000 ANSI lumens of brightness is more than enough for decent HDR performance, but I preferred the higher brightness I saw with SDR content. Even in my light-controlled space.
As I've noted in past reviews, Optoma's color engineers are some of the industry's best. This is clear when running through the projector's movie and game-centric preset picture modes.
The UHZ55 offers a comprehensive range of color adjustments, making it easy to tailor the image to your liking. If skin tones appear too red or the image seems too blue, you can fine-tune the color and gamma settings to achieve the perfect balance. Like other Optoma models, the UHZ55 delivers good color accuracy immediately and even better results with professional calibration.
In the gallery above, I captured several stills in different modes and with various content to highlight the differences between specific preset modes. These demonstrate how each mode impacts the image quality and helps you choose the best settings for your viewing preferences.
Optoma projectors have several preset modes to enhance your viewing experience based on content and room lighting conditions.
The best modes for Standard Dynamic Range (SDR) content are CINEMA, HDR-SIM, and REFERENCE. CINEMA mode is ideal for movies, offering rich colors and deep contrast. HDR-SIM mode boosts contrast and color depth, giving SDR content an HDR-like quality. REFERENCE mode prioritizes color accuracy, making it perfect for those who value true-to-life colors.
BRIGHT mode is best for its high brightness in rooms with uncontrolled ambient light, though it sacrifices some color accuracy. GAME mode provides a good balance with dynamic colors and a warmer image, making it more pleasant than BRIGHT mode in moderately lit environments. For those who want custom settings, USER mode allows full programmability to suit specific needs and preferences.
If you want to make quick BRIGHTNESS, CONTRAST, and SHARPNESS adjustments to improve the picture quality of your projector in your room, there are several free test patterns available on t the Murideo website and their YouTube channel. Murideo also has written instructions in the resource section of its website. Also, check out our YouTube video on utilizing several test patterns called Optimize The Image of a Projector or TV Using Free Murideo Test Patterns.
The Optoma UHZ55 offers good color performance, particularly for its price range. However, users seeking the most accurate color reproduction may want to consider professional calibration, something we strongly recommend doing here at Projector Reviews.
Optoma claims that the UHZ55 can display 3,000 ANSI lumens of brightness, and based on my experience with other Optoma DLP projectors, I expect it to measure close to that claim. As with most projectors, using the most accurate picture modes on the UHZ55 results in a noticeable drop in brightness, which is perfectly fine for viewing in a dark room.
I measured the brightness by taking 3-4 readings from about 15-20% out from the center of the lens. This method approximates ANSI lumens well unless the projector's brightness significantly diminishes at the edges, which the UHZ55 does not.
The brightest picture preset on the Optoma UHZ55 is BRIGHT mode, while the brightest lamp source setting is NORMAL. These settings provide maximum brightness, making them suitable for well-lit environments.
How close did the Optoma UHZ55 come to hitting its target of 3,000 lumens?
According to my testing, the UHZ55 measured 3278 lumens in the projector's BRIGHT picture preset mode. This reading exceeded the manufacturer's rating by 278 lumens.
The chart below shows my measurements of the projector's out-of-the-box picture modes.
Optoma UHZ55 4K Preset Mode's Brightness | ||
---|---|---|
Picture Modes | Brightness Measured (ANSI Lumens) | |
CINEMA | 2091 ANSI Lumens | |
HDR-SIM | 2247 ANSI Lumens | |
GAME | 2227 ANSI Lumens | |
REFERENCE | 1167 ANSI Lumens | |
BRIGHT | 3278 ANSI Lumens | |
USER | 3257 ANSI Lumens |
The UHZ55 has an average dynamic contrast rating of 2,500,000:1, and while that's not low, dynamic contrast ratings tend to be the least conservative numbers of almost all the manufacturer's performance ratings. I can tell you that the UHZ55's black floor is about the same as that of similarly featured Optoma projectors. That is to say, they are more of a deep gray approaching charcoal.
The blacks will not compete with the deep, inky blacks found on LCOS projectors. However, the UHZ55 produces surprisingly good black levels for a single-chip DLP projector. The UHZ55 does provide decent contrast with nice details in the darker areas of displayed images.
As you can see in my screen captures in the gallery above, the projector does a decent job showing details in the darker areas of the picture.
The UHZ55 has a Dynamic Black feature that enhances shadow detail by dynamically adjusting the laser output, revealing more details in darker scenes. The UHZ55 maintains good shadow detail without excessively crushing displayed blacks. When this feature works, it's great. However, there are times when the stepping effect of lowering the output of the projector's light source is noticeable, and at these times, I find myself shutting it off.
This projector's black levels and overall contrast performance make it ideal for a mixed-use environment, which is exactly how Optoma positions the UHZ55. It is an excellent home theater and gaming projector designed for living room environments.
The photos in the galleries above mostly feature dark scenes, where you can still see a decent amount of detail in the shadows. The UHZ55's black levels are better than average and significantly superior to projectors that use traditional lamp-based light sources. This results in a richer, more detailed viewing experience, especially in low-light scenes.
HDR has four out-of-the-box presets: BRIGHT, STANDARD, FILM, and DETAIL. FILM is the most accurate to my eye, but all the modes offer similar brightness. If your room is fully darkened, FILM mode is best for a good movie. Some other presets may have more punch, but FILM mode makes movies look the best.
HDR is often difficult to display accurately on a projector. You can't always see a dramatic difference between the projector's HDR mode and the same content in SDR. However, that's not the case with the UHZ55. HDR modes on this projector display with color that is just a bit oversaturated. When watching Dune: Part Two and Mad Max: Fury Road in HDR, two movies purposely mastered to provide dramatically saturated colors, especially during the desert scenes, the UHZ55's tendency to overdrive the colors made scenes borderline unnatural. Even in more muted scenes, like any of the Atlantis scenes from Aquaman: The Lost Kingdom, characters seemed almost video-game-like. Dark area detail was quite good in most HDR content, which is great for both movies and gaming.
The difference between HDR and SDR on the UHZ55 is not dramatic, but it is noticeable, with most content looking better in SDR.
Here are some images from various videos and photos in 4K and HD resolution. These photos have not been adjusted for color and are as close to what I saw onscreen as my camera could capture. What I saw onscreen actually looked a bit better to me.
We are pretty lucky with the sheer amount of high-quality content currently available. For overall video quality, I tested various 4K and HD content from top streaming platforms like Max, Apple TV, and Disney+, which offer many movies in 4K HDR. So much content on streaming is still Standard Definition, but this Optoma 4K projector's upscaling is excellent.
Blu-ray images were crisp, with few compression artifacts and YouTube videos also looked fantastic, especially with a good internet connection. Even older, lower-resolution content, like the Standard Definition version of Moonlighting, scaled up well with minimal distortion.
While the Optoma UHZ55 is a Home Entertainment projector, it is also a great option for gaming enthusiasts. The UHZ55 has a GAMING mode with a 17 ms input lag for 4K/60Hz gaming and as low as 4.4 ms for 1,080p/240Hz gaming. Optoma has an excellent history of gaming performance on its dedicated gaming projectors, and I'm happy to say that gaming on this projector was not only a smooth, judder experience but also fast. The low input lag ratings of the various resolutions meant there was only an almost imperceptible delay from when I pressed a button on my Xbox controller to the corresponding screen action.
The built-in 20-watt (10-watt x2) sound system is usable but uninspiring, and I expected better from a home theater and gaming projector. Although better than a mono speaker, the Optoma UHZ55’s sound is not very dynamic, and the projector's stereo imaging is lacking.
I strongly recommend that users of this projector take advantage of the upgraded eARC functionality to connect to an external sound system to get the best overall movie and gaming sound experience from the UHZ55. The UHZ55 eARC supports PCM, Dolby Digital/+, and DTS-HD signals. However, the eARC function is supported only if the source is HDMI1.
The fan noise is relatively low; I found it only noticeable when a movie or show was quiet or my game paused. The Optoma UHZ55 is a quieter projector than most, and audible noise is not an issue.
The UHZ55 uses a blue laser plus phosphor system that powers Optoma's BrilliantColor technology and covers 85% of the DCI-P3 color gamut, enhancing the overall viewing experience. In my testing, this projector looked its best when set to SDR mode. The colors looked well-balanced and looked great, depending on the preset picture mode selected. Also, the projector has a decent Color Management System (CMS), allowing it to be professionally calibrated.
The Optoma UHZ55 is a 4K DLP projector with an estimated street price of $2,499. It utilizes a single DLP (0.47" DMD) chip to reproduce 4K UHD resolution (3,840 x 2,160 pixels). The UHZ55 measured 3278 ANSI lumens, which are 278 lumens higher than Optoma's estimated brightness rating of 3,000 ANSI lumens. In my experience testing the projector, the UHZ55 provided more than enough brightness to enjoy movies with the lights on or in the daytime.
HDR modes disappointed me by displaying oversaturated colors and sometimes making some people onscreen look cartoonish. This was not a problem with SDR modes.
While not LCOS level, the UHZ55's black-level performance is still very good for this type of projector. Blacks are not easily crushed, and there is an acceptable amount of dark area detail, making watching movies, TV, and games enjoyable.
The UHZ55 offers wireless connectivity and some smart functionality via the included USB WiFi dongle or wired RJ45 connector. The USB adaptor provides users with wireless internet connectivity and access to Optoma's application portal, where a small number of apps are available for this projector. Internet access is also available via the projector's RJ45 wired connector.
While there is a lot I like about the UHZ55, there are several things I do not. The projector's native streaming applications are severely limited, with the only major streaming services available for download being Netflix and Prime Video. The limited amount of popular streaming apps alone makes me strongly recommend an external streaming device.
Users can buy a brand new Google TV stick or FireStick for $19.99 from multiple providers, offering them full access to thousands of applications far above what Optoma's app market offers and, frankly, of better quality.
The remote is sluggish, and the remote sensor placement can make it troublesome for the remote and projector to communicate with each other. The processor that controls the menu system seems underpowered, providing an overall sluggish experience when using the onscreen menus. Also the Optoma app store just does not have enough content. If Optoma wants to remain competitive, it needs to start offering Google TV as part of its projector package, even if it means packaging an HDMI streaming dongle with the projector.
Lastly, this projector's onboard audio performance is not near where it should be for a projector meant for home entertainment and gaming. The sound is not very dynamic or immersive.
Despite its flaws, the UHZ55 offers impressive features and picture quality and is worth considering if you are looking for an all-around home entertainment projector.
