Description
The Optoma ZH420 is one of Optoma's most compact and hassle-free Full HD 1080p DuraCore laser projectors to date. It delivers 4,300 lumens with a 300,000:1 contrast ratio (2,000,000:1 dynamic) and accepts 4K UHD/HDR input, while the laser light source is rated for 30,000 hours of maintenance-free operation. A 1.16-1.49:1 throw ratio and 1.3x zoom cover screen sizes up to 322 inches, with 360-degree and portrait projection for flexible installation. Dual HDMI 2.0 inputs, RS232 and RJ45 control ports support both corporate AV and home entertainment use, and an external power supply improves reliability and portability. Built with sustainability in mind, the ZH420's chassis uses up to 50% post-consumer recycled plastics and packaging with up to 97% recyclable materials, alongside up to 45% lower power consumption than a comparable lamp-based projector.
