The Christie® 4K7-HS combines the cost-savings of 1DLP® technology, the long illumination performance of laser and the image quality of 4K UHD resolution. The result is a high-performance 7,000 lumen, 4K UHD, HDR10 compatible laser projector that won’t blow your budget.

What makes the 4K7-HS outperform the competition is the enhanced color performance thanks to the patented Christie BoldColor Technology. Colors appear natural and with the added fidelity of 4K UHD resolution, visuals are lifelike and clearer than ever.
