Firstly, a cinema projector pays attention to the stability, theheatdispersion, and the network function, emphasizing the low failure rate, whichis easy to use;

Secondly, a cinema projectors’ brightness generally up to 5000 lumens, some may exceed10,000 lumens;

Thirdly, cinema projectors are projected to support the HDCP protocol broadcasting, thatis to say, the company has signed an agreement with the film company. If not the cinema's device, it does not support HDCP protocol which can’t display properly, and this is the biggest difference between cinema projectors, general commercial use projectors and project projectors.
