The Optoma ZK431ST is a 4K UHD (3,840 x 2,160) DLP business and education projector built around a DuraCore laser light source rated for up to 30,000 hours. It puts out 4,100 lumens with a short-throw lens, so it fills a large screen from close to the wall and casts fewer shadows on a whiteboard. Four-corner correction, keystone adjustment, 360-degree orientation and the Optoma Smart App cover installation and alignment. Against lamp-based 1080p classroom projectors it trades a higher upfront outlay for no lamp swaps and sharper text; against brighter large-venue 4K laser models it gives up some light output.

The Optoma ZK431ST is a short-throw laser DLP projector for classrooms, conference rooms and other business or education spaces. It has 4K UHD (3,840 x 2,160) resolution, which gives up to 8.3 million pixels, and 4,100 lumens of brightness for rooms with moderate ambient light. The short-throw design reduces shadows in limited spaces.
The DuraCore laser light source is rated for up to 30,000 hours of lamp-free operation, so there are no lamp replacements. It turns on and off instantly and uses less power. The light source is mercury-free.
Setup tools include H/V keystone correction with a slide dial, four-corner adjustment, and Smart Fit, which uses a smartphone camera to align the image to the screen frame automatically. Smart Move detects obstacles with the camera and repositions the projection to a clear area. The Optoma Smart Control app works as a remote for power, input switching and status alerts. The projector also supports over-the-air firmware updates and can be managed through Optoma Management Suite, either in the cloud or over a local network.
