Spectacular 100” Full HD 1080p image from only 12” away

Equip space-constrained environments with the 4,000 lumens 1080p Optoma ZH420UST, driven by laser-phosphor technology for stunning images with up to 30,000 hours of life from the light source. A throw ratio of 0.25:1 enables 100-inch projections from 12 inches away, ideal for small classrooms, meeting rooms, boardrooms and digital signage.

Built-in warping adjustments provide image manipulation and projection onto virtually any geometric surface, including support for up to 17 x 17 individual point adjustments. The geometric flexibility makes combining multiple ZH420USTs to produce one large, bright and ultra-wide image easy.

Amazing Color

Our projectors are capable of reproducing the Rec.709 color gamut, the international HDTV standard to guarantee accurate reproduction of cinematic color exactly as the director intended.

Full HD 1080p

1080p (1920×1080) resolution renders sharp and detailed images from HD content without downscaling or compression, which is perfect for movies, TV shows and gaming.

Ultra Short Throw

Ultra short throw projection enables closer placement to the wall with reduced shadows for easy presenting. The placement makes it perfect for interactive applications and education environments, too.

DLP Technology®

DLP® (Digital Light Processing) is a proprietary technology from Texas Instruments™ that offers digital projection with higher contrast, faster response time, good pixel structure and virtually no color degradation.

Full 3D

Display true 3D content from almost any 3D source, including 3D Blu-ray Disc™ players, 3D broadcasting, and the latest-generation game consoles. Support for 144Hz rapid-refresh rate provides ultra-smooth flicker-free images. DLP Link 3D glasses required.

MHL Connectivity

Turn your projector into a smart display by connecting your smartphone or tablet with a single cable using MHL; now you can view presentations and documents, stream videos and share photos on the big screen.
