The Pro8530HDL is the perfect solution for large venue Pro AV projection requirements, thanks to a centred lens, sealed engine and multiple adjustment features like vertical lens shift, 1.6x optical zoom, horizontal & vertical keystone, plus 4-corner adjustment. Utilising a unique Flex-In (Flexible Installation) design, the Pro8530HDL integrates an intuitive form with high flexibility and an easy installation process, making it the ideal installation projector. Equipped with 5,200 lumens and Full HD resolution, the Pro8530HDL is powered by SuperColor and SonicExpert to provide a professional audiovisual performance. It boasts a bilateral opening top cover, 4x HDMI (1 of which is MHL) and an intuitive PortAll compartment to accommodate optinal HDBaseT solutions (an affordable way of transferring High Definition audio and video over long distance), wireless dongles, or PC stick integration for versatile application. The sealed optical engine prevents dust and moisture from affecting the lighting system, ensuring the image quality is maintained for a long period of time. This tool-free dial controls the lens shift function easily for vertical adjustments without any loss of optical quality. This feature provides flexible projector placement for challenging installations, with less locational limitations. Equipped with a 1.6x optical zoom lens, the LightStream projector provides mounting flexibility with a wider throw distance range. This zoom lens also enables the projector to project images up to 60% larger than a conventional projector equipped with a fixed focal lens. Horizontal and vertical Keystone correction, plus auto vertical Keystone eliminates crooked and distorted images for a perfectly proportioned picture every time. The automatic vertical keystone (and 4-corner adjustment) also improves usability and makes setup and image positioning more convenient. Horizontal and vertical Keystone correction can only solve symmetric distorted image problems. When it comes to non-symmetric crooked images, 4-corner adjustment can make images right. With a centred lens position, the projector is easy to align and even easier to set up, without having to guess and tediously adjust your surroundings. ViewSonic's Flex-In design provides flexible installation that brings easy adjustment and maintenance. The tool-free and simple top cover design provides users ample room to adjust or change a dongle or lamp conveniently, making ceiling mounted applications easier to manage. This projector comes equipped with Crestron RoomView Express, an easy-to-use network management system that lets administrators remotely observe and control over 250 projectors from a single PC, such as power on/off, lamp life etc.
