Advantages and Disadvantages
Advantages
- Bright, accurate 4K HDR/HLG support with laser illumination for long life and stable output.
- Short-throw optics enable large images from close distances—great for small rooms and tight installs.
- Extensive geometric correction (keystone, four-corner, 5x3 warp), digital zoom and image shift simplify alignment.
- Comprehensive connectivity: HDMI, USB power, RS-232, RJ45 with Crestron/Extron/PJLink/AMX support and web control.
- Gaming Mode reduces input lag significantly (down to 4.4ms at 1080p240), plus multiple picture presets and CMS tuning.
Disadvantages
- 3D mode limitations: 4K not supported and requires 60Hz/1080p for best performance.
- Advanced features and network setup require some AV/network knowledge for full use and security configuration.
- Digital zoom can degrade image quality compared to optical adjustments.
- Some model-dependent features (HDR, HDMI 2.0 specifics, accessories) vary by region and SKU.
- Regular maintenance needed: keep vents clear and follow lens-cleaning precautions to avoid damage.

Frequently Asked Questions
Throw distance and image size depend on the short-throw lens ratio and chosen model. Refer to the projector's distance table for exact values; generally short-throw models produce large images from short distances, ideal for small rooms.
Is this answer helpful?
Yes — HDR and HLG are supported on compatible HDMI inputs. The projector can auto-detect HDR/HLG signals and enable HDR processing to enhance dynamic range, deeper blacks and brighter highlights. HDR mode may override other picture presets while active.
Is this answer helpful?
Connect an RJ45 cable, configure DHCP or manual IP under Control > LAN, then access the projector's web interface using its IP address (default credentials: admin). It supports Crestron, Extron, PJLink, AMX and HTTP/Telnet control for integration.
Is this answer helpful?
Keep intake and exhaust vents unobstructed with at least 30 cm clearance, avoid dusty or humid environments, use a soft cloth or compressed air for lens cleaning, power down and allow the cooling cycle before unplugging, and follow manufacturer-recommended service procedures.
Is this answer helpful?
Yes. Enable Gaming Mode to reduce input lag significantly. Input lag varies by resolution and refresh rate — for example, it can be as low as 4.4 ms at 1080p240, while 4K60 in Gaming Mode measures around 16.9 ms.
Is this answer helpful?
The unit is a Class 1 laser product (Risk Group 2) compliant with IEC and FDA regulations. Avoid staring into the beam, supervise children, and do not disassemble the projector to prevent hazardous exposure.
Is this answer helpful?
Use High Speed or Premium Certified HDMI cables (up to recommended lengths) to ensure signal integrity, especially for 4K/HDR content. Proper cabling helps avoid handshake and image-quality issues.

Product Description
Optoma UHZ35ST — Powerful Short-Throw 4K Laser Projector
The Optoma UHZ35ST is a high-performance short-throw laser projector designed for home cinema, gaming, and professional AV installations. Combining laser illumination with DLP technology and extensive image controls, it delivers bright, accurate 4K images from a compact chassis and short throw distance, making it ideal for rooms where space is limited but picture quality is paramount.
This projector emphasizes longevity and reliability thanks to a laser light source with long life and stable output. It supports multiple predefined picture modes — Vivid, Cinema, Reference, Game, Sport, Bright and DICOM Simulation — so users can quickly choose an image profile tailored to movies, gaming, sports or specialized grayscale content. HDR and HLG processing are supported on compatible inputs, automatically switching when HDR content is detected to maximize dynamic range and color depth.
Installation is flexible: the UHZ35ST supports 360° orientation, multiple projection orientations (front/rear/ceiling), extensive geometric correction tools (V/H keystone, four-corner adjustment, 5x3 warp), digital zoom and image-shift functions to precisely align images without physically moving the unit. Short-throw optics provide large images from close distances, and the projector includes zoom and focus controls plus adjustable feet for quick setup.
Connectivity covers modern AV needs: dual HDMI inputs (HDMI 2.0 where applicable), USB power out (5V/1.5A), RS-232 for legacy control, RJ45 network for web-based management and remote control protocols (Crestron, Extron, PJLink, AMX). LAN control and an integrated web server let administrators power on/off, adjust brightness, and monitor status remotely. The keypad and dual IR receivers give flexible local control, while user-programmable remote buttons and HDMI CEC support simplify daily use.
Advanced image tuning includes a full CMS (color, hue, saturation, luminance), BrilliantColor™ options, selectable color temperatures, gamma presets, and wall-color correction modes for projecting onto painted surfaces. A comprehensive OSD menu and multilingual support make configuration accessible; OSD items can be locked for secure deployments. For gamers, a dedicated Gaming Mode reduces input lag dramatically (down to 4.4 ms at 1080p240 in ideal settings).
Safety and maintenance are covered with clear guidance: ventilation clearance, environmental operation limits, laser safety notices, lens-cleaning precautions, and procedures for powering down and cooling. The unit supports password protection, security timers, and configurable power behaviors (Direct Power On, Signal Power On, auto power-off and sleep timers).
Notes:
- Short-throw design is perfect for small rooms or tight installations; measure throw distance against the projection table for precise sizing.
- Use High Speed or Premium Certified HDMI cables for best results, and keep vents unobstructed for reliable cooling.
- For 3D, use DLP-Link glasses and recommended frame rates; 4K content is not supported in 3D mode.
