Description
The ZH450 brings Full HD 1080p resolution to Optoma's compact DuraCore laser projector line, offering 4,500 lumens of brightness in a chassis up to a third smaller than earlier lamp-based equivalents. A 1.4-2.24:1 manual zoom lens gives installers flexibility over throw distance without needing a short throw or ultra short throw variant.
The sealed, IP6X-rated laser engine is rated for up to 30,000 hours, effectively eliminating lamp changes and filter maintenance over the projector's working life, while an external power supply improves reliability and keeps the unit compact. Laser illumination also means instant power-up and shutdown, useful in back-to-back classroom or meeting room bookings.
With a 300,000:1 contrast ratio, a 15W integrated speaker and a chassis built with recycled plastics as part of Optoma's Eco Promise, the ZH450 is a practical, low-running-cost Full HD projector for education and corporate spaces that need dependable everyday brightness.
