High brightness projection with Easy Stacking Function  Projector stacking delivers outstanding brightness in a unique budget-friendly solution
Stacking involves placing up to four projectors across for example an auditorium, so that brightness can be multiplied and redundancy is achieved in the event that one projector is not operating.
Stacking is a perfect solution for achieving high brightness as high as 30,000 ANSI lumen, at a much lower cost compared to buying one 20,000 ANSI lumens projector. With all the benefits of being able to combine the projectors into one room or separate them into a number of rooms at your control.
With stacking, as the projectors are ordinarily spaced out horizontally, image on-screen isn’t blocked when someone walks past the front of the screen as the unblocked projectors still can project their image.
In addition NEC has created simple to use but powerful Stacking Correction software so that you can quickly and easily achieve a perfect set-up. A stacking configuration is easy because of the Geometric Correction
Processing built into the projectors, the camera for the processing and the newly developed dedicated software when installing the projector. Since the adjustment data will be stored in the projector, the PC and the camera are no longer required after initial setup.
Projectors can also be temporarily removed and used individually and a stacking solution can still work when one projector fails. |
