Optoma ZK430ST3700 Lumen UHD 4KShort

Optoma ZK430ST — a 3,700-lumen UHD 4K short-throw laser projector designed for bright meeting rooms, classrooms, and simulation environments.

The Optoma ZK430ST delivers full 3840×2160 (4K UHD) resolution from a short-throw optical design, allowing a large image from a short distance — useful in rooms where a standard-throw projector would need to be mounted far back or create shadowing. At 3,700 ANSI lumens, the image remains legible in a well-lit room. The laser light source provides up to 30,000 hours of operation with no lamp replacement, and instant-on/off eliminates the cooling wait of lamp-based projectors. 4K HDR support covers HDR10 and HLG for compatible content. Two HDMI 2.0 inputs handle 4K/60Hz sources. Suited to corporate AV, simulation, higher education, and large home cinema rooms with limited throw distance.
