Optoma ZK521ST-B 4K UHD Short-Throw Laser DLP Projector - Black

The Optoma ZK521ST 4K UHD Short-Throw Laser DLP Projector (White) brings native 4K ultra-high-definition resolution and high-output laser reliability into a versatile short-throw design. 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 absolute clarity. Furthermore, its advanced media processing supports HDR10 and HLG input signals, delivering brighter whites, deeper black levels, and an expanded color gamut for an immersive viewing experience in well-lit environments.

At the core of the ZK521ST 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 professional installations and specialized simulator setups.

Engineered with a dedicated short-throw lens, the projector creates a large, immersive image from close proximity to the projection surface. This effectively eliminates bothersome presenter shadows and glare, making it exceptionally well-suited for golf simulators, interactive museum exhibits, and compact boardrooms. Installation is further simplified with a 1.2x optical zoom, horizontal and vertical keystone correction, and four-corner geometric adjustment. Additionally, its sustainable design utilizes an energy-efficient power supply and a durable white chassis built to blend seamlessly into modern ceilings or media rooms.
