Easy stacking function of NP1250 projectors enables higher brightness projection cost-effectively. Cinematic video is powered by HQV (Hollywood Quality Video).¤¤The high brightness equivalent to about 20000 lumens at maximum can be achieved. Since multiple projectors project images, it is possible to arrange the projectors so that the images on the screen will not be disrupted even if the power of either one of the projectors is turned off or anybody or anything obstructs the front of one of the projectors displaying images. Although it used to take time to set up a stack installation with ordinary projectors, a stack configuration with this projector is easy because of the geometric correction tool built into the projector, the camera for the adjustment, and the newly developed dedicated software when installing the projector.
