Christie has been constantly evolving their best-selling M Series line of projectors since their introduction in 2007, and that tradition continues with the M 4K25 RGB 3DLP laser projector.
A hallmark of the M Series since its inception has been its small, rugged design. The new M 4K25 RGB, that starts shipping this November, is 20.7 x 24.3 x 106.6 inches (HWD) and 92 pounds without a lens. Within that enclosure is a dust-sealed 0.95-inch 3DLP chipset capable of 4K UHD (3840×2160) resolution up to 60 Hz and 96% of the Rec. 2020 color gamut. There’s a Mirage upgrade that ups that to 120 Hz in both 2D and 3D stereoscopic formats, and a Mirage Pro upgrade option provides frame rates up to 480 Hz at UHD resolution.
The RGB laser light source outputs 22,500 ANSI lumens (25,000 ISO lumens) of brightness and has a life of up to 50,000 hours before reaching half brightness. The light source can be serviced and replaced in the field as well. Christie’s proprietary LiteLOC technology automatically manages the light source brightness over time to keep its presentation consistent. A self-contained liquid cooling system keeps the projector running cool and quiet, with a rated sound level up to 46 dBA in standard mode in an environment up to 72 degrees Fahrenheit.

Since it’s an M Series projector, the M 4K25 RGB is compatible with the M Series rigging frame and can be placed in any orientation. It is also compatible with existing M, J, and Crimson Series lenses. The Christie range of standard lenses can provided throw ratios as low as 0.37:1 and as high as 10.4:1 and a contrast ratio of 2,000:1 in standard fan mode. Ultra-high contrast zoom lenses (that will be available in early 2022) range from 1.3-2.5:1 and provide a 7,000:1 contrast ratio, although brightness is reduced by 30%.
The M 4K25 RGB doesn’t have swappable input/output cards, instead having all connections built-in. Included are four 12G-SDI, two HDMI 2.0, two DisplayPort 1.2, HDBaseT, Fiber for use with a Christie Link Transmitter, SDVoE, a 3D sync, and audio out. Christie’s Terra SDVoE connectivity allows for uncompressed 4K signals with zero latency over 10G networks. A full-color LCD panel provides full control of the projectors menus and TruLife+ electronic color convergence, which can also be accessed through a web interface, which individually adjusts red, green, and blue with a remote.
