The Optoma ZK430ST is a short-throw 4K UHD laser projector that produces 3700 lumens of brightness and delivers clear, detailed images even when some ambient light is present. It is well suited for home theaters, classrooms, conference rooms, and retail displays where space is limited yet high image quality is important.

At the heart of the ZK430ST is Optoma’s DuraCore laser light source, rated for up to 30,000 hours of operation. This long service life removes the hassle and cost of routine lamp changes, keeps brightness consistent over time, and lets the projector power on quickly whenever you need it.

The projector supports HDR10 and HLG content, which means scenes show deeper blacks, brighter highlights, and more accurate colors. Whether you are streaming movies, sharing design work, or presenting data-heavy graphics, the added contrast and color precision help every detail stand out.

A 0.496:1 short-throw ratio lets you create a large image from a short distance, so the projector can sit close to the screen or wall and stay clear of foot traffic and shadows. This makes installation easy in small rooms, training spaces, or storefront windows.

Flexible orientation options broaden its use. Portrait projection, 360 degree mounting, and a chassis that is rated for round-the-clock operation open the door to digital signage, exhibition displays, and simulation setups. An IP6X sealed optical engine keeps dust out, which protects image quality and reduces maintenance.

Two HDMI inputs accommodate media players, laptops, and game consoles, while a USB-A port supplies power for a streaming stick. Horizontal and vertical keystone adjustment allow quick alignment so the picture stays square even if the projector is not perfectly centered.
