The Nec NP610 is a very versatile projector providing 3,500 lumens. It is suitable for both educational and business environments. It projects clear and bright images and is well suited for large screens. It has a DVI digital video connection, to be able to project high quality images. It is one of the few projectors that, apart from the vertical keystone, has a horizontal keystone that allows us to correct the shape of the image if we are going to project laterally. In addition, it is a very quiet projector: only 29 dB, even with its high brightness.
