Product Overview
Optoma ZK430ST 4K UHD Short-Throw Laser DLP Projector, 3700 Lumens, HDR/HLG.
The Optoma ZK430ST is one of Optoma’s most compact and hassle-free 4K UHD resolution DuraCore laser projectors to date. Designed for maintenance-free continuous operation, this 3,700-lumen projector delivers powerful image performance with flexible installation features and extensive connectivity options in a sleek, compact form factor, up to 34% smaller than previous Optoma projector models.
To support Optoma’s commitment to sustainability, the ZK430ST cuts power consumption by up to 45% compared to Optoma’s lamp-based projectors. Energy-saving 4K laser projector DuraCore technology ensures a long product lifespan of up to 30,000 hours without the need for additional lamps, requires minimal maintenance, and is mercury-free, further lowering its carbon footprint.
As an added benefit, the Optoma ZK430ST features an external power supply offering more reliability, portability and energy efficiency.
Designed with the environment in mind, the eco-friendly chassis is made with up to 50% PCR (Post-Consumer Recycled) plastics and the packaging contains up to 97% recyclable materials. In addition, the compact product and packaging size of the Optoma ZK430ST 4K DLP projector allows twice more products carried per container, resulting in more efficient logistics to help further reduce carbon emissions.
Geared for conference rooms, boardrooms, and other corporate spaces, the ZK430ST 4K laser projector has a short throw lens, meaning it can be positioned less than two feet from any wall. For ultimate convenience, it comes with RJ45 and RS232 connection for monitoring and controlling, and a built-in speaker.
