Vivid Clarity in Bright Medium-Sized Conference Rooms 3,600 lumens of high brightness enable comfortable lights-on presentations to promote discussion, collaboration, and note-taking in larger meeting rooms with bright lights accommodating up to 20 participants. The high luminance lets even participants seated furthermost clearly see the slides and boosts picture quality with vibrant color for pictures and videos as well as crisp text and fine details. High Contrast for Clear Text With industry-leading contrast and pixel fill factor, BenQ projectors produce the truest blacks and unmatched readability with every character, graph, and chart crisply defined. High fill factor increases clarity for black and white or color images and reduces eye strain for presenters and audiences to stay focused on the content. Integrated 1.5A USB Type-A Power Output In addition to conveniently charging any mobile device, built-in 1.5A USB Type A power output empowers accessories such as wireless HDMI dongles without need for separate power adapters. Universal Multi HDMI & VGA Connectivity Dual HDMI inputs in addition to dual VGA inputs are purpose-engineered to host multiple presenters and their laptop or mobile devices without taking time to take turns. Multiple inputs enable meeting participants to collaborate instantly without complicated adapters or time-consuming IT support. Vertical Keystone for Perfect Alignment Countering the trapezoid effect when the projector must be placed off-center, such as simple placement on top of a table, vertical keystone function adjusts the image for a professionally squared image. Keystone correction makes it easy to project ideally aligned images from a variety of locations.
