Optoma ZK431ST Laser Projector

An exceptional image changes how a space is experienced. The Optoma ZK431ST Laser Projector brings Optoma projection technology into a considered setting, pairing visual presence with the practical capabilities required for a well-designed installation. A compact 4K UHD short-throw laser projector rated at 4,100 lumens with a 0.496:1 throw ratio, in a white chassis for business and education.

It has very low input lag (16.7 ms at 4K/60Hz, 8.6 ms at 1080p/120Hz), OMS and Smart Control app management, over-the-air updates and a 15W speaker, and is rated for 24/7 use. That combination matters in real-world use: the projector is intended to support classrooms, conference and meeting rooms, commercial spaces, where image scale, visibility and consistent operation shape the experience for everyone in the room.

Behind the image is a carefully considered technical platform. Model-specific capabilities include 4K UHD; laser (30,000 hrs Eco); 0.496:1 short throw; white chassis; 16.7 ms (4K/60) / 8.6 ms (1080p/120) input lag; OMS; Smart Control app; FOTA; 15W speaker; 2x HDMI 2.0 (4K HDR); 3D sync; 12V trigger; 24/7. These details are more than a specification list: they inform placement, signal integration, day-to-day operation and the degree of control available to the installer.

At Vanté Living Innovations, we favor technology that feels intentional in its surroundings and rewarding in everyday use. This Optoma projector offers a sophisticated foundation for engaging viewing and presentation experiences. Confirm the model's projection geometry, environmental requirements and connection needs against the intended space to create an installation that performs as beautifully as it belongs.
