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 20,000 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.
NEC Stacking Solutions operate with differing ANSI Lumen Projectors. So NP2250 units can for example be combined with NP3250 units. Projectors can also be temporarily removed and used individually and a stacking solution can still work when one projector fails. |

SIMPLE STEPS TO SET UP STACKING
- Place the selected projectors alongside each other
- Power up each Projector
- Perform rough Optical Adjustment of Focus Zoom and Lens Shift
so all Projected Images are just covering the screen
- Connect all Projectors to a common network via LAN or WLAN.
- Set up a standard camera or Web Cam
- Open the NEC Stacking Correction Program
- The Software will find the addresses of all projectors on the network automatically
- The Camera settings are checked using a standard test pattern sent to the projector via the network
- The software automatically adjusts each Projector using Various Camera Images of Test Patterns
- The Stacking Set up is completed after 2-3 minutes. the frame of the screen was detected automatically
