Step 4: Define size of input image section to display
The visible area of the monitor wall has an aspect ratio of 220 cm : 120 cm, or 16.5 : 9. To compare the
aspect ratios of the input image and the video wall, we divide the width by the height.
Video wall:
120 cm / 220 cm = 1.8333
Input Image:
16 / 9 = 1.7778
This means the video wall is a little wider than our 16:9 input image. We choose the width of the video wall
to be equivalent to 9000 units.
Step 5: Calculate units per centimeter
Divide the width of the input image section, 9000 U, by the width of the wall, 220 cm, to get the density of
our video wall,
9000 U / 220 cm = 40.909 U/cm , 40.909 units per cm.
Step 6: Measure size for each display
To calculate the sizes for all displays, we need to measure the physical size of the displays in the
Taking the center display as an example, we measure the width (76.5 cm) and height (43 cm) of the
display. Take care to always measure the active part of the screen, not the frame.
The pixel density of the video wall is 40.909 U/cm, so we can transform the physical size into coordinates
by multiplying with the density.

76.5 cm

40.909 U/cm = 3129.54 U
