implement this kind of display system.
The output aspect ratio will be changed depending on the display system. User needs to take
care of the aspect ratio in the source content in advance.
k.
Edge blending will increase the total resolution. Usually, the video quality will be good enough for most
of the applications if output resolution in each projector can reach XGA resolution.
l.
User can connect with other signal sources like Blue Ray or Media Player to other input ports in
VWC-44
.
By
selecting different input ports and applying different
AV-BOX
settings, it will provide different display
modes. For
example, for 3 projector edge blending, user can set all three edge blending, two projector
edge blending and one
has discrete display or each projector has independent content.
m.
AV-BOX
can reduce the CPU loading in PC and reserve more CPU resource to handle interactive
or
other operation without image lag.

Case D: “L/M” shape video wall with edge blending
Below is example of the application in restaurant with “L” shape video wall:
a. 3x WXGA projectors: two projectors edge blending on the front screen and another projector is located
at side wall.
b. The image is met at the corner. It is not necessary to do edge blending at the corner. User just needs to
do geometry alignment to let the image meet at the corner.
c. User can use Video Wall function to split the image into 3x (using ZOOM function) and use PAN and
OVERLAP function to capture the right size of the image and assign to each projector.
d. Three projectors should have the same image captured size to avoid different scaling factor in the
projectors. It can be adjusted through Video Wall Overlap function.
e. To do edge blending on the front two projectors and the image in side wall only needs geometry
alignment and Video Wall setting. User can use any model of
AV-BOX
that has video wall
function
inside.
