Under [Offset] menu, user can try [Gain] and [Offset] color compensation to let non-transition and
edge blending area to have the same color. After this step, user will see grey bars near the
borders of edge blending area. User can use [Corner] to eliminate these grey bars.

Image quality fine tuning
The final performance will be a combination of many factors—projector characteristics,
projector
setting, screen, ambient light and
AV-BOX
setting.
Banding in overlap area under dark environment is caused by light leakage in the projector optic
system. It is not possible to be fixed by signal manipulation. The only way is to raise the black
level in none transition area through [Offset] menu.
AV-BOX
edge blending default setting is for projector with 2.2 gamma settings. To
select
projector display mode near 2.2 gamma setting will get the best result.
The projector may retain light leakage near the border of the imager. It is not possible to be fixed.
The factors affect final image quality
i.
AV-BOX
settings:
Edge Blending settings: Gamma, gain, Offset, Color
Image Properties: To select Preset Mode to Neutral, sRGB or Bluish
Individual projector color adjustment [Color] function under [Edge Blend] menu.
ii.
Projector:
To adjust image position of the projector and reduce keystone angle.
Increase Overlap region & reduce off axis angle
To change Display Mode, usually Standard, sRGB/Neutral will get better result.
Try different color settings. If necessary to use 3D color adjustment in the projector.
iii.
Screen: To use lower gain value screen.
13.8 Edge blending with
VWC-44
+ 104
a
、
It is possible for user to use
VWC-44
+ 104 for 3 projector project. The default grid pattern size in
VWC-44
is 32x32 pixels/Grid and 104 is 50x50 pixels/Grid.
b
、
We propose user to apply any external grid pattern from PC or to use Gwarp to set grid size at
50x50 pixels for
VWC-44
geometry alignment. Then it can match the grid pattern in 104.
c
、
Continuously press [Pattern] key in
AV-BOX
will change the color of internal grid pattern and
user will also find external grid pattern from signal source.
d
、
Use [Warp] menu to do geometry alignment in 104 first, then use [3x3 Curved] and 5x3 Curved]
alignment in
VWC-44
to align the grid pattern together.
e
、
After finish geometry alignment, please execute Video wall setting and Edge blend settings. The
procedures are the same in both
VWC-44
and 104.
