Description

The Optoma ZH451 is built with Miracast technology for seamless wireless display sharing and presentations, without extra hardware, simplifying collaboration in meeting rooms, classrooms and other professional spaces. It delivers 4,600 ISO lumens from a DuraCore laser engine, cutting power consumption by up to 45% compared with Optoma's lamp-based projectors. With Optoma Management Suite (OMSC), IT managers can remotely manage the ZH451 and other compatible devices from the cloud, with effortless control, real-time monitoring and scheduling to reduce downtime. The projector is also compatible with the Optoma Smart Control App for quick adjustments from a phone. A 1.6x zoom lens, 360-degree and portrait projection give flexible mounting options, while dual HDMI 2.0 and VGA inputs, RS232, RJ45 and a 15W speaker cover typical boardroom and classroom connectivity needs.
