Key Features of the Optoma UHZ35ST
- Short-Throw Lens: Projects a massive 120-inch screen from just 4.4 feet, making it ideal for smaller spaces.
- 4K UHD Resolution: Delivers sharp, pixel-perfect image clarity at 3840 x 2160 resolution.
- Laser Light Source: Offers 30,000 hours of low-maintenance performance with DuraCore laser technology.
- Enhanced Game Mode: Ultra-low input lag at 4.4ms (1080p/240Hz) and 16ms (4K/60Hz) for competitive gamers.
- Brightness Rated at 3,500 Lumens: Handles both dark and moderately lit rooms with ease.
- HDR10 and HLG Compatibility: Dynamic Black enhances contrast and color depth, claiming a 500,000:1 ratio.
While its features seem impressive on paper, the real-world performance and comparisons with alternatives reveal where it truly shines—and where it doesn’t.
Display Quality: Immersive 4K… With Caveats
True 4K UHD Resolution
The UHZ35ST achieves 4K UHD resolution using XPR pixel-shifting DLP technology, which reproduces a true 3840 x 2160 image on screen. Movies and games look crisp and full of detail, and the resolution is a major step up from traditional 1080p projectors. Content like UHD Blu-rays and streaming 4K content on platforms like Netflix and Prime Video shine on a large screen.
Despite this, the HDR performance lacks the visual punch that enthusiasts seek. HDR10 and HLG (broadcast HDR) are supported, but colors often feel muted, particularly in scenes with vibrant highlights or saturated hues. The black levels are adequate but fail to match the precision achieved by competitors like the BenQ X3100i or Epson HC3800, which feature more robust HDR rendering and superior contrast handling.
Brightness and Contrast
While marketed as delivering 3,500 lumens, real-world measurements peg peak brightness closer to 2,500 lumens—which, though slightly overstated, is still respectable. It performs well in brightly lit living rooms and moderately controlled environments. For scenes requiring deep contrast, the promised contrast ratio of 500,000:1 doesn’t hold up well, as blacks often appear more grayish than pure black.
In darker environments, the image can appear a bit washed out compared to Epson’s LS12000 or BenQ’s TK860i, which excel in fantastic contrast depth and effective HDR pop.
Display Performance Verdict: Excels at sharpness and brightness for mixed lighting scenarios, but HDR performance and black levels fall short when compared to class leaders.

Gaming Performance: A True Competitive Edge
Gaming is where the UHZ35ST absolutely dominates. Gamers will love its responsiveness, delivering 4.4ms input lag at 1080p/240Hz, 8.5ms at 1080p/120Hz, and 16ms at 4K/60Hz. Competitive games like Fortnite, Call of Duty, and Valorant feel fluid, and casual single-player experiences get the added boost of cinematic visuals on a large screen.
Additionally, the 240Hz refresh rate at 1080p ensures ultra-smooth motion, vital for FPS shooters or fast-paced sports games. That said, enabling Enhanced Game Mode locks out geometric corrections like keystone, meaning you’ll need precise physical placement for distortion-free gameplay.
For gamers on a budget, the ViewSonic PX701-4K, with low lag and similar features, is cheaper. However, it lacks the brightness, brevity of lag, and performance consistency seen in the UHZ35ST, making Optoma the better long-term choice for serious gamers.
Gaming Verdict: Outstanding performance for gamers seeking a massive screen with rapid response times. This is its strongest feature.
Ease of Installation and Portability
The short-throw lens is a highlight of the UHZ35ST—it enables a 120-inch screen size from just 4.4 feet and up to 300 inches at longer distances. This makes it ideal for small or compact spaces where a traditional long-throw projector wouldn’t usually work.
Weighing just 6.61 pounds, it’s easy to set up and move around. However, the absence of zoom and lens shift means you’re stuck relying on manual adjustments or imperfect digital keystone corrections, which can reduce brightness and add distortions. In contrast, competitors like the Epson HC3800 offer horizontal/vertical lens shift, greatly simplifying proper alignment.
For users who need easy installation features, the UHZ35ST may feel restrictive unless placed optimally.
Installation Verdict: Compact and versatile for short-throw setups, but lacks flexibility found in slightly larger alternatives.
Audio and Connectivity
Audio
The built-in 15W mono speaker is serviceable but falls far short of providing immersive sound. Output is tinny, and at higher volumes, it distorts. The lack of EQ options in the settings further limits audio tuning. Gamers or movie enthusiasts should connect to a Dolby Atmos soundbar or a receiver (via eARC) for satisfactory results.
Connectivity
The UHZ35ST includes:
- 2 HDMI 2.0 ports (1 with eARC for high-quality audio pass-through).
- 1 USB-A (5V/1.5A) for media sticks like Fire TV.
- RJ-45 Ethernet for network integration.
- RS-232 port for advanced control setups.
- 3.5mm audio out for external audio systems.
While functional, the lack of Wi-Fi, Bluetooth audio, or built-in streaming apps feels dated, especially compared to projectors like the BenQ TK860i or LG CineBeam projectors, which integrate Smart TV platforms for direct access to apps like Netflix or Disney+.
Connectivity Verdict: Sufficient for most home setups, but outdated for those craving advanced wireless streaming or audio options.

Eco-Friendly Design
A standout feature is its eco-conscious construction:
- The chassis utilizes 50% recycled plastics, paired with 97% recyclable packaging materials.
- The DuraCore laser reduces maintenance and eliminates mercury-based lamps.
- Power consumption is up to 45% lower than lamp-based projectors, offering reduced long-term energy costs.
Beyond sustainability, the sealed light engine with IPX6 dust resistance ensures longevity in harsh conditions—a perfect solution for extended usage or environments prone to dust.
Competitive Comparisons
Finding the best projector requires understanding trade-offs relative to alternatives. Here’s how the UHZ35ST stacks up:
1. BenQ X3100i ($2,199)
- Pros: Superior HDR rendering, Smart TV functionality via Android OS.
- Cons: Slightly bulkier, higher price.
- Verdict: A better choice for HDR content enthusiasts but less portable and pricier than the UHZ35ST.
2. Epson HC3800 ($1,499)
- Pros: Outstanding black levels, adjustable lens shift.
- Cons: Slower gaming response (~24ms latency).
- Verdict: Perfect for home theaters; gamers may prefer the UHZ35ST’s speed.
3. ViewSonic PX701-4K ($999)
- Pros: Affordable, decent gaming latency.
- Cons: Lower brightness and inferior build quality.
- Verdict: The PX701-4K is ideal for budget users but falls behind in premium gaming performance and overall durability.
Final Verdict
The Optoma UHZ35ST is a versatile projector that excels in gaming performance, portability, and usability in compact spaces. It balances ultra-low latency and crisp 4K visual fidelity, making it an excellent choice for gamers seeking large-screen experiences. Its eco-friendly build and DuraCore laser light source make it a fantastic long-term investment for those who value maintenance-free operation.
However, for hardcore home theater enthusiasts, the lackluster HDR performance, limited placement flexibility, and basic audio system might make other projectors, like the Epson HC3800, a better fit. Similarly, users needing smart features or integrated connectivity may feel the absence of wireless/Wi-Fi technologies.
Who Is It For?
- Best For: Gamers, small-room users, and those seeking eco-conscious designs.
- Not Ideal For: Advanced home theaters or buyers wanting integrated Smart TV functionality.
The UHZ35ST shines brightest in hybrid use cases and delivers tremendous performance for its size. While slightly pricey, its strengths make it worth considering for users prioritizing gaming and portability.
