Optoma ZK420UST Ultra Short Throw DLP 4K UHD 4200 ANSI lm Laser Projector, White

The Optoma ZK420UST is an ultra-short-throw projector that uses DLP technology to produce a native 4K UHD (3840 x 2160) resolution. Its laser light source provides 4200 ANSI lumens of brightness and is rated for up to 30,000 hours of operation, which minimizes maintenance requirements. The 0.25:1 throw ratio allows the device to project a large image from a short distance, suiting it for installations in smaller rooms or where space is limited.

This model supports High Dynamic Range content through HDR10 and HLG standards, paired with a 500,000:1 dynamic contrast ratio to improve image detail in varied lighting. It has a native 16:9 aspect ratio and is designed to project an image between 100 and 150 inches diagonally. The unit also includes support for 3D content and various preset video modes for different ambient light conditions.

Connectivity options include two HDMI 2.0 ports, a USB-A port, and an Ethernet LAN port for network control. A single 15-watt built-in speaker provides onboard audio for basic presentations or media viewing. The unit is designed for tabletop or ceiling-mounted placement and includes a remote control for operation, along with an automatic power-off function to conserve energy.
