Vertical= 1080/Y=Y’
d.
To measure the positions in each LCD between the display area and outside borders or center lines
of the video wall.
e.
The final position adjusting value ([Overlap] pixels) will be as following pixels:
TV1: Left Edge= -X1L * X'
，
Right Edge=+X1R * X'
，
Top Edge=0
，
Bottom edge= -Y1B * Y’
TV2: Left Edge = -X2L * X'
，
Right Edge =0
，
Top Edge = -Y2T * Y’
，
Bottom edge = +Y2B * Y’
TV3: Left Edge = 0
，
Right Edge = -X3R * X'
，
Top Edge = -Y3T * Y’
，
Bottom edge = 0
TV4: Left Edge = +X4L * X’
，
Right Edge = -X4R * X'
，
Top Edge = -Y4T * Y’
，
Bottom edge = 0
The above value has already taken bezel compensation into consideration.
5.2.2 Aspect Ratio issue and blanking border in the image
The final display aspect ratio will be X:Y. If user wants to keep 16:9 aspect ratio, then user needs to
adjust the display area and let X:Y=16:9. The position for each LCD will be also changed. However,
the method for calculate [Overlap] value is still the same as above.
The content for the display should have the same aspect ratio as the outlines of the video wall to
avoid image distortion. User can also set none VESA standard output timing with this aspect ratio.
If blanking border appears in the video wall, user can reduce the [Overlap] value to enlarge the
image, then store the settings into [Profile] for this special input source.
5.2.3 More complicated irregular video wall position adjustment
The procedures for this example are similar to 2x2 irregular video wall mentioned in previous section. The
major difference is the base lines for the measurements. In this case, the [Zoom] value in video wall setting
is H=3, V=2. Therefore, user needs to split the image into 3x2. The measuring base lines will be based on
Red & Pink lines in the above drawing.
a.
To calculate the pixel numbers in each measure unit, i.e. “mm” (pixel density)
(Assume to connect with 1920x1080 input signal while doing position adjustment)
Horizontal= 1920/3X=X’, Vertical= 1080/2Y=Y’
b.
The final [Overlap] adjusting value will be as follows (TV1 & TV3 as examples)
