The Home Cinema projector ZH551 from Optoma features a 4K UHD resolution and an image size ranging from 20 - 300". The size depends on the distance between the projector and the projection surface, which is adjustable within 1 - 9.3m.
DLP (Digital Light Processing) technology is the most widely used projection technology. The image is created when the projector's lamp light passes through a rotating color wheel and is reflected by a chip with hundreds of thousands of tiny mirrors, known as DMD (Digital Micromirror Device). DLP projectors are suitable for well-lit environments such as school rooms or conference halls, providing good color performance.
This projector has a brightness of 5100 ANSI Lumens and a contrast ratio of 3000000:1. Contrast ratio indicates the difference between the darkest and brightest parts of an image, serving as a quality indicator. A projector with a low contrast ratio may appear washed out, while one with a high contrast ratio offers a more realistic image with greater depth.
Brightness indicates the projector's ability to project light over a specific surface size. The brighter projectors are recommended for use in spaces with ample lighting.
The projector is equipped with a Ethernet port to enable wired connections to the local network, allowing streaming online content or software updates.
