Four Christie HD8k projectors, horizontally and vertically edge-blended to create a 4k image at 25,000 ANSI.

HD projection and design took a further leap forward when QED's senior av technician Adam Bending successfully edge-blended four true High Definition projectors vertically and horizontally to form a single "extreme HD" image of 4k resolution, and at an astonishing 25,000 ANSI lumens in brightness.

This short video is taken from a locked off camera pointing at the screen. The awesome 8.8 megapixel canvas was generated by a high performance multihead PC with four individual graphics outputs each of 1920 x 1080 pixel resolution arranged in a 2x2 display array through QED's Spyder system.

Several native HD sources including live camera, Blu Ray, HD-DVD and PC were all run simultaneously in real time and brought in as true HD picture-in-picture windows over the 4k background.

For extremely high resolution images then QED's "Extreme HD" is the way to achieve a high pixel count and high brightness over any size and shape of canvas. For more information and details on the benefits of "Extreme HD" please contact Paul Wigfield.
