Optoma - DLP-projektor

The Optoma ZK451 is a laser DLP projector designed for presentation and multimedia environments that demand detailed 4K UHD imagery and reliable, continuous operation. It delivers 4,500 lumens of brightness and a high contrast ratio to maintain clear, legible content in well-lit rooms while supporting large image sizes and flexible throw distances for varied installation needs. The long-life laser light source provides up to 30,000 hours of operation for reduced maintenance, and comprehensive connectivity including multiple HDMI inputs, USB ports, VGA, and wired LAN enables easy integration with meeting-room systems and network management. Built-in image adjustments such as vertical and horizontal keystone correction, a manual 1.6x zoom lens, and 360° projection support simplify setup, while a built-in 15 watt mono speaker and a low noise level of 29 dB help maintain focus during presentations. Security features including a Kensington slot, security bar, and password protection support fixed installations and shared spaces where device control is important.
