Optoma ZK430ST 4K UHD Short Throw Laser Projector
Description
The ZK430ST brings native 4K UHD resolution to Optoma's compact short throw laser projector line, using a 0.496:1 fixed lens to produce a large, detailed image from close to the screen. At 3,700 lumens it's aimed at classrooms and meeting rooms rather than large auditoria, prioritising sharpness and colour over sheer brightness. The DuraCore laser light source is rated for up to 30,000 hours behind a sealed IP6X-rated optical engine, so the projector needs no lamp replacements and keeps performing reliably through years of daily use. Laser illumination also gives instant on/off, useful for rooms booked back-to-back through the school or working day. With a 300,000:1 contrast ratio, a built-in 15W speaker and a compact eco-friendly chassis, the ZK430ST offers a straightforward route to 4K UHD short throw projection for education and small business spaces that don't need the extra brightness of the larger ZK series models.
