The Christie CP4450-RGB pure laser cinema projectors defines the premium movie-going experience for large format theatres. Featuring CineLife+ electronics and RealLaser illumination, this compact DCI-compliant projector excels in image quality, operational lifetime, and onscreen brightness. With the CP4450-RGB, exhibitors can impress audiences with incredibly colorful and detailed, true-to-life 4K images while benefiting from a platform designed to support the content and formats of the future.

What you don’t see

Built on the CineLife+ platform, the CP4450-RGB is capable of displaying HFR titles in 4K at 120 frames per second. With this new system architecture and ultrafast processing, audiences won’t see the motion blur typical of the giant screen experiences. These projectors deliver artifact-free images in 2D and 3D. This adds to the already heightened sense of realism created with Christie RealLaser illumination.
