NEC's machine is quite good. It takes a long time to make a projector, which is specially used for projectors. The product line is also relatively complete, from low-end entertainment projectors to business projectors, to portable projectors, to engineering projectors, NEC is very professional. NEC also has some patented technologies of its own, such as air-cooled pump technology, which is very good for the projector to dissipate heat and has its own focus, that is, when adjusting the size of the screen, the projector can focus itself, which is also a very good function. Let's not talk about it. Qianli Projection City is the general agent of NEC projectors. For details, please consult the professional engineer of Qianli Projection City.
