Product Summary
The Optoma ZK521ST is a professional 4K UHD short throw laser projector engineered to deliver bright, detailed images in spaces where installation distance is limited. With 5,300 lumens of brightness, true 3840 × 2160 Ultra HD resolution, and long-lasting DuraCore laser light source technology, it provides crisp presentations, immersive visuals, and dependable performance without the maintenance associated with traditional lamp projectors.
