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.

width:

76.5 cm

40.909 U/cm = 3129.54 U≈3130 U
