Optoma ZK431ST-B 4K UHD Short-Throw Laser DLP Projector - Black

The Optoma ZK431ST-B 4K UHD Short-Throw Laser DLP Projector (Black) brings native 4K ultra-high-definition resolution and laser reliability into a remarkably compact, stylish black chassis. Operating at a native 3840 x 2160 4K UHD resolution, it displays over 8 million addressable pixels on screen, rendering exceptionally crisp text, intricate graphics, and cinematic textures with true-to-life clarity. Furthermore, its advanced media processing supports HDR10 and HLG signals, delivering brighter whites, deeper black levels, and an expanded color gamut for an immersive viewing experience.

At the core of the ZK431ST-B is Optoma’s advanced DuraCore Laser light source, featuring an IP6X dust-resistant optical engine. This lamp-free technology eliminates the recurring expenses, hassle, and downtime of traditional bulb replacements while providing up to 30,000 hours of continuous operation in Eco mode. It also enables instant power-on and power-off functionality, maximizing efficiency for both residential media rooms and commercial setups.

Engineered with a dedicated short-throw lens, the projector creates a large, immersive image from close proximity to the screen. This effectively eliminates bothersome presenter shadows and glare, making it exceptionally well-suited for golf simulators, media rooms, and interactive spaces where discreet aesthetics are desired. Installation is further simplified with a 1.1x optical zoom, horizontal and vertical keystone correction, and four-corner geometric adjustment. Additionally, its sustainable design utilizes an energy-efficient external power supply and a chassis built with post-consumer recycled (PCR) plastics.
