4.4. Get installation data from VNS Excel Spread Sheet
➢
VNS can provide an Excel Spread Sheet for user to calculate necessary installation data for the
project. It is important data for installation and setup.
➢
Below are assumptions for the above 3x projectors edge blending system Excel calculation.
✓
Screen Size: 6.5m*1.5m with watching distance within 2m (pixel pitch less than 2mm)
✓
Input signal resolution: 3840*800 (Pixel pitch is 6500mm/3840=1.7mm = 1.7m watching
distance, optimized vertical resolution is the same as projector native resolution: 800)
✓
Number of projectors: 3 projectors
✓
Projector resolution and lumens. 1280*800 (native resolution), 3200 Lum
✓
Overlap pixels and dimension. 8 grids=8*32= 256 pixels (50cm)
✓
Projector throw ratio: 1.2-1.7 (based on projector spec)
➢
How to operate VNS Excel Spread Sheet
✓
Input all the data in Yellow column, including Source Resolution, Projector Resolution
(GeoBox output resolution), Screen size, Projector throw ratio, Projector Lumens, No. of
projector and Overlap Pixels. User can try different configurations and select the most cost
effective one with the image height a little higher than required.
✓
User will get below data from the Spread Sheet.
-
Final image size for each projector is 250cm*1.56cm with Overlap region of 50cm in width.
-
The image height should be higher than the required one. User can shrink the vertical
height to required dimensions through geometry alignment. The vertical adjustment range
in each edge is 1200 pixels.
-
Optimized content resolution: 3328*800 (This is the ideal resolution to set EDID). It is
suggested to select the same vertical resolution (800) as projector native resolution to get
the best result.
