The Optoma ZK400 is a 4K UHD laser projector that delivers 4000 lumens of brightness, so images stay clear even when the lights are on. It suits conference rooms, classrooms, sports bars, and public venues where large, detailed visuals need to cut through ambient light.

Inside, a DuraCore laser engine drives the picture and is rated for up to 30,000 hours of use. That means years of operation without lamp replacements or frequent maintenance. Support for HDR10 and HLG brings extra depth to shadows and highlights, while a 2,000,000:1 contrast ratio helps subtle details stand out on screen.

Installation is flexible. A 1.5 to 1.66:1 throw ratio and manual 1.1x zoom give you room to place the projector where it fits best. Horizontal and vertical keystone correction up to ±30 degrees, along with four-corner adjustment, make it easy to square the image on uneven surfaces. The chassis also supports 360-degree orientation and portrait mode, an advantage for digital signage and creative staging.

Connectivity covers most modern sources. Three HDMI 2.0 ports handle 4K signals from media players, gaming consoles, and streaming devices. A USB-A port can power an adapter or wireless dongle, and audio outputs feed external sound systems if the built-in 20-watt stereo speakers are not enough. Gamers and fast-action content benefit from a 4 ms input lag that keeps on-screen motion responsive.

Designed for 24/7 duty cycles, the ZK400 is a reliable choice for museums, retail displays, and control rooms where downtime is not an option. Mount it on the ceiling, hide it in an equipment rack, or set it upright for a towering portrait display—the projector is built to stay bright, sharp, and dependable day after day.

  • Native 3840 × 2160 resolution produces true 4K UHD images
