5 Advance settings: Bezel compensation and location alignment
5.1 Bezel compensation
Usually, if the bezel size is less than 5mm, many people may not do any bezel compensation unless user needs
to get accurate alignment. In the above example, if we want to do bezel compensation for all TVs, then we need
to apply [Overlap] function under [Video Wall] menu as below:
Assumption:
a.
Bezel size: Horizontal: 10mm, Vertical: 12mm
b.
TV screen size: 47” (1040mmx585mm)
c.
Input resolution: 3840*2160 (after video wall setting, each TV will receive 1920*1080 signal)
d.
Bezel size:
Horizontal=1920/(10+1040)*10=18.3 pixels
Vertical=1080/(585+12)*12=21.7 pixels
Bezel compensation for TV1:
a.
Right Edge: -18 (enlarge the image to Right direction for 18 pixels)
b.
Bottom Edge: -22 (enlarge the image to Bottom direction for 22 pixels)
Bezel compensation for TV2:
a.
Left Edge: -18 (enlarge the image to Left direction for 18 pixels)
b.
Bottom Edge: -22 (enlarge the image to Bottom direction for 22 pixels)
Bezel compensation for TV3:
a.
Right Edge: -18 (enlarge the image to Right direction for 18 pixels)
b.
Top Edge: -22 (enlarge the image to Top direction for 22 pixels)
Bezel compensation for TV4:
a.
Left Edge: -18 (enlarge the image to Left direction for 18 pixels)
b.
Top Edge: -22 (enlarge the image to Top direction for 22 pixels)
Tip:
a. [Overlap] value is to change the image capture range for each TV. If we reduce the value, then less image will
be showed in the TV—it means the image will be ZOOM IN (enlarged). If we increase [Overlap] value, then
more images will be showed in the TV—it means the image will be ZOOM OUT (shrunk).
b. In the above example for TV1, Left Edge is the border of the image, there are no image can be capture. If
user increases [Overlap] value to “+” position, the image has only few lines in Blanking Area for capture.
Example for irregular TV wall:
TV size: 47” (1040x585mm)
TV resolution: 1920x1080
Grid pattern: 16x9 grids
Each grid=6.5x6.5mm
Each grid: 120x120 pixels
