Short description

The Optoma ZH350ST is designed for businesses, educational institutions, and AV integrators that need a compact short-throw laser projector for continuous operation. With its short-throw lens (throw ratio 0.496:1), it can also be installed in tight spaces without a large wall distance. The IP6X certification protects the device against dust ingress – a clear advantage in industrial or public environments. Thanks to 360° projection and portrait mode, the ZH350ST can be used flexibly in almost any orientation.

Advantages and special features

  • Full HD resolution (1,920 x 1,080) for sharp presentations and video display
  • Laser light source with 30,000 hours – no lamp replacement required
  • IP6X certified: completely dust-tight for demanding operating environments
  • Short-throw lens (throw ratio 0.496:1): 100-inch image from a wall distance of approx. 1.10 m
  • 360° installation and portrait mode for maximum mounting flexibility
  • Approved for 24/7 operation – designed for continuous operation in shift-work and signage applications
  • 3D-ready (DLP 3D) with 120 Hz PC frame sequential support
  • Compact housing: 274 x 216 x 114 mm, net weight 3.0 kg

Image and sound quality

The ZH350ST uses DLP technology and a native Full HD resolution of 1,920 x 1,080 pixels. The laser light source delivers 3,500 ANSI lumens with a contrast ratio of 300,000:1. Image uniformity is 75%. The device displays 1.0734 billion colors and supports the 4:3, 16:9, and 16:10 aspect ratios.

Horizontal and vertical keystone correction covers ±30° each; automatic vertical keystone correction is integrated. Input lag is 8.60 ms – relevant for time-critical applications. 3D content is reproduced via DLP 3D, PC Frame Sequential (120 Hz), and Blu-ray/DVD 3D.

The integrated mono speaker delivers 15 W. For larger rooms or higher audio requirements, a 3.5 mm audio output is available.

The ZH350ST features two HDMI 2.0 inputs as well as an RS232 control port. A USB-A output (1.5 A) enables the power supply of external devices. Wireless expansion is possible via the optional UHDCast Pro module – this is not included in the delivery.

Mounting and installation

The ZH350ST supports table-top, ceiling, and rear projection, as well as 360° installation in any orientation including portrait mode. Operation is approved at temperatures from 0°C to 40°C, a maximum humidity of 80%, and up to 2,500 m above sea level.

The delivery includes: AC power cable, remote control (card style), 2× AAA batteries, and a basic user manual.

The native lens offset is 116%. A manual zoom function is available; lens shift is not built-in.

For wall distance planning: The housing depth is approx. 21.6 cm (W × D × H: 274 × 216 × 114 mm). Add approximately 7–12 cm for the connector and cable exit.

According to the manufacturer, this projector supports image sizes from 30 inches (76 cm) to 300 inches (762 cm).

The projection distance specified by the manufacturer is at least 0.30 m and at most 3.30 m.

Image diagonal Image width (approx.) Projection distance
80 inches 177 cm approx. 0.88 m
100 inches 221 cm approx. 1.10 m
120 inches 265 cm approx. 1.31 m

The calculated projection distances are based on the manufacturer's throw ratio and serve as guidelines. Since the measurement points (e.g., from the center of the lens vs. the front of the housing) often vary in data sheets, a centimeter-accurate calculation is not always guaranteed.

Security features: The ZH350ST is equipped with a Kensington lock port as well as a password-protected interface.

Operating and follow-up costs

Power consumption is a maximum of 139 W during operation, 98 W in eco mode. In standby mode, consumption is below 0.5 W.

No regular lamp replacement required – low maintenance in continuous operation.

Operating mode Lifespan 2 hrs/day 8 hrs/day
Laser normal operation 30,000 hours approx. 41.0 years approx. 10.5 years
ECO mode not available

In the event of a service requirement, the light module replacement must only be carried out by a professional workshop.

Conclusion

The Optoma ZH350ST combines Full HD image quality, short-throw optics, and a dust-tight laser light source in a compact 3.0 kg housing. The 30,000-hour lifespan and 24/7 approval make it economical for continuous operation scenarios such as digital signage or training rooms. IP6X protection and 360° installation freedom expand the possibilities of use to demanding environments where conventional projectors reach their limits. The 15 W speaker and dual HDMI 2.0 setup cover typical installation requirements without additional hardware.
