The portable Optoma ML550 3D Ready Mobile LED Projector delivers 500 lumens of brightness with a sharp 10,000:1 contrast ratio. It features WXGA 1280 x 800 widescreen resolution and can project up to a 100″ diagonal 2D or 3D image. The ML550 is powered by a DMD DLP chip system and its LED light source features a long lifespan of 20,000+ hours. This means you’ll save money because there are no traditional projector lamps to buy or replace. LEDs are also more energy efficient and they produce less heat.
This model also provides multiple connectivity options including HDMI and VGA via a 24-pin universal port. The ML550 supports PC-less presenting via USB, microSD or 1.5GB internal memory. These three options support a variety of file formats including PowerPoint, Excel and Word files/documents. The projector has a built-in 1W mono speaker as well. Other features include a low standby power consumption level that’s less than 1W and a complete on-screen menu that supports adjustments in 16 different languages. This projector even affords wireless presenting, although the optional BI-EXTBGN adapter is required.
