➢
In multiple projector applications, the Overlap value can be determined by VNS Excel Spread
Sheet as showed in below chart with RED mark. User can follow this value to get the right overlap
settings with clear image.
➢
This Overlap value will be calculated based on several factors
—such as input resolution, projector
native resolution (GeoBox output resolution), quantity and overlap region size.
➢
If the overlap regions have different size due to installation position limitation, please use Irregular
Excel Spread Sheet to calculate overlap value.
➢
User can use Video Wall overlap setting to fine-tune the image position in overlap region. It can
compensate geometry mis-alignment and let image become much clearer.
6.4. [Position]: shift image position without changing image size
After cropping, user can shift image position at H&V directions without changing image size. Usually, it is
for video wall application to fine tune image position. In projector edge blending application, user only
changes Overlap value in one edge but not execute image position shift.
