Optoma ZK430ST Short Throw DLP 4K UHD 3700 ANSI lm Laser Projector, White

The Optoma ZK430ST is a short-throw projector that utilizes DLP technology and a DuraCore laser light source. It projects a native 4K UHD resolution of 3840 x 2160, providing detailed images for business and educational applications. With a brightness of 3700 ANSI lumens and a dynamic contrast ratio of 300,000:1, the device is designed to maintain image clarity in rooms with ambient lighting. It supports High Dynamic Range content, including HDR10 and HLG formats, to enhance detail in both bright and dark areas of the picture.

Connectivity options include two HDMI 2.0 ports for high-resolution sources and a USB 2.0 Type-A port for service or power. An Ethernet LAN port enables network-based control and management within an existing infrastructure. The integrated 15-watt speaker provides onboard audio for presentations. The laser light source is rated for up to 30,000 hours of operation, reducing maintenance requirements compared to traditional lamp-based systems.

Designed for flexible placement, this model features a 0.496:1 short-throw ratio, enabling it to project a large image from a short distance away. This makes it suitable for smaller meeting rooms or classrooms where space is limited. The projector can be positioned on a table or mounted to a ceiling, with setup assisted by vertical and horizontal keystone correction of ±15 degrees. The chassis is white, with dimensions of 274 x 216 x 114 mm.
