Design and Build Quality
The ZH350ST features a compact and lightweight design, making it easy to transport and set up in various environments. Its black chassis is sturdy, with well-placed ventilation to prevent overheating during extended use.
The lens is positioned for short-throw projection, allowing it to be placed close to the screen or wall, which is ideal for small rooms or tight spaces.
Brightness and Image Quality
With a brightness rating of 3,500 lumens, the ZH350ST performs well in well-lit rooms, making it suitable for classrooms and conference rooms where ambient light cannot be completely controlled.
The projector uses DLP technology and has a native resolution of 1280×800 (WXGA), which provides clear and sharp images for presentations, videos, and general multimedia content.
Color accuracy is decent for business and educational applications, though it may not satisfy professional video editors or home theater enthusiasts seeking high-fidelity color reproduction.
Short Throw Capability
One of the standout features of the ZH350ST is its short-throw lens, which can project a 100-inch image from just around 1 meter (3.3 feet) away.
This reduces shadows cast by presenters and allows for flexible placement in small rooms. The short throw also minimizes the risk of the projector being in the way or obstructing the audience’s view.
Connectivity
The projector offers a variety of input options including HDMI, VGA, USB, and composite video, ensuring compatibility with most laptops, desktop computers, and media players.
It also supports 3D content, which can be a bonus for educational or training environments that make use of 3D visuals.
Audio
The built-in 10W speaker provides adequate sound for small to medium-sized rooms, eliminating the immediate need for external speakers in basic setups.
However, for larger venues or applications requiring higher audio fidelity, connecting external sound systems is recommended.
Ease of Use
Setup is straightforward, with keystone correction and manual focus adjustments helping to quickly achieve a clear and properly aligned image. The projector’s menu system is user-friendly, and it comes with a remote control for convenient operation.
Lamp Life and Maintenance
The Optima ZH350ST projector uses a lamp with an average lifespan of around 6,000 hours in Eco mode, which helps reduce maintenance costs and downtime. Replacing the lamp is relatively simple, and the projector includes filters that are easy to clean or replace.
Noise Level
The fan noise is moderate but generally unobtrusive during presentations. In quieter environments, it may be noticeable but not distracting.
Pros:
Bright 3,500 lumen output suitable for bright rooms.
Sharp WXGA resolution with good image clarity.
Short throw lens ideal for small spaces and reducing shadows.

Verdict:
The Optoma ZH350ST is an excellent choice for businesses, schools, and other environments requiring a bright, short-throw projector that is easy to set up and use.
Its strong brightness and flexible placement options make it particularly well-suited for small to medium-sized rooms with ambient light.
While it may not meet the needs of high-end home theater users or professional color work, its value and performance for general multimedia and presentation purposes are solid.
