Compact short-throw laser projector

The Optoma ZH350ST is a new DLP business projector with a 0.496:1 throw ratio, letting it fill a 300-inch diagonal image from just over three metres away. Its 3,500-lumen laser light source delivers Full HD 1080p brightness for meeting rooms, classrooms or signage installations that need a large picture in tight spaces.

HDMI 2.0 input limits

Two HDMI 2.0 ports accept 1080p signals up to 120 Hz vertical refresh and 140 kHz horizontal refresh, so modern laptops and media players connect without adapters. The single 3.5 mm audio output and 15 W built-in speaker handle basic sound, while RS-232 and a 1.5 A USB-A power port support control systems and streaming sticks.

30 000-hour laser life and image range

The maintenance-free laser is rated for 30 000 hours at full power, removing lamp replacements for years of daily use. Native 16:9 content scales across 30 to 300 inches diagonal with 300 000:1 static and 2 000 000:1 dynamic contrast, but the fixed 0.496:1 throw ratio means rooms needing longer projection distances or lens shift will require a different model.

Questions about this item

What image size can I get with the 0.496:1 throw ratio in a small room?

The short-throw lens produces a 30 to 300 inch diagonal image from 11.81 to 129.92 inches away, so a 100 inch picture needs roughly four feet of throw distance.

How does the 3500 lumen rating look in a lit meeting room?

At 3500 lumens the 1080p DLP image stays readable with lights on, and the 300000:1 native contrast keeps dark detail visible without washing out.

What does the dual HDMI 2.0 input actually support?

Two HDMI 2.0 ports accept 1080p at up to 120 Hz, plus 4:3 and 16:10 signals, while the USB-A port supplies 1.5 A for streaming sticks.
