Stacking is a low cost, flexible way to achieve up to 44,000 ANSI Lumen from our standard projectors. It involves placing up to four projectors across for instance, an auditorium, so that brightness can be multiplied and redundancy is achieved in the event that one projector or more are not operating.
With stacking, the on-screen image isn’t blocked when the presenter walks past the front of the screen as the unblocked projectors still can project their image filling up to 75% brightness in the shadowed area.
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. Suitable NEC projector series are PA, PX and PH series..

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
