The Optoma ZK420UST is a short-throw projector that offers 4K UHD resolution and a bright 4200 ANSI lumen laser light source. Its ultra short throw lens allows projecting an image up to 100 inches from less than 12 inches away, making it a convenient solution for spaces with limited room. This projector is well suited for both business use and educational environments where precise and bright images are needed.
The projector’s 3840×2160 resolution guarantees detailed and sharp image quality. It supports HDR technology in Hybrid Log-Gamma (HLG) format, enhancing image contrast and color reproduction. This ensures images and videos are displayed naturally and clearly.
The laser light source provides a bright 4200 lumen output that remains consistent for up to 30,000 hours. Laser technology also ensures fast startup and less maintenance compared to traditional lamp projectors.
The projector features two HDMI 2.0 ports supporting eARC audio, as well as RJ-45 and RS-232 serial connections. Additionally, it includes a 3D sync port, enabling 3D content viewing. The built-in speaker delivers 15 W of sound, and remote control operation is easy.
A throw ratio of 0.25:1 and fixed zoom allow projecting a large image very close to the surface. This reduces shadow formation and space requirements, which is convenient for meeting rooms and classrooms.
The projector’s design is intended for business use: it is compact, weighs 4.5 kg, and includes a Kensington cable lock slot. The noise level is 34 dB in normal mode and 29 dB in eco mode, keeping distractions to a minimum.
A wide range of OSD languages, including Finnish, facilitates settings management. The projector operates at temperatures from 0–40 °C and tolerates relative humidity of 0–80%, making it suitable for various environments.
