New GITEX Christie introduces the new J series projector range

Christe is a very well known projector manufacturer. The opening of The Atlantic in Dubai was, in fact, done using the company's projectors. They are at Gitex to showcase some of their new products this year. One of them is the Christie J series range, a compact (in its class) projector solution that combines the best of the company's innovations into one affordable package (if ever these things can be affordable). The most interesting feature of the projector is the Christe Twist, a hardware-based pixel mapping technology that can adjust any image onto the surface it is projecting on, and stitch multiple images into one seamless image. An example is below. The Christe J series is also fitted with the 3-chip DLP platform along with 22,000 lumens of Xenon brightness to help deliver proper color accuracy and clean, crisp images. The J series comes in various low to high-end models, with the Christe Roadster HD20K-J featured above carrying a price tag of USD 80,000.
