To calculate the height, in pixels, of the active screen area of the monitors:
Measure the distance from A to C but only the active screen area, i.e. do not include the outer bezels.
In this example A to C = 900mm.
Measure the active screen area between A and G
In this example A to G = 448mm.
Calculate the following:
The distance between A to G (448mm) divided by the distance between A to C (900mm) multiplied
by the source height (1080).
(448 ÷900) x 1080 = 538
Input the number 538 as the Height for each region.
Top and Left Measurements
The Top and Left dimensions determine where each region is placed over the source canvas. As in all
computer graphics applications, the top left corner is taken to be the origin. (0,0)
Region 1
In this configuration, monitor 1 (Region 1) is displaying the top left of the source canvas, therefore Top
should be zero and Left should also be zero.
Enter zero in both the Top and Left box.
Region 2
Monitor 2 (Region 2) is displaying the top of the source canvas, therefore Top should be zero, the same as
monitor 1 (Region 1).
Enter zero in the Top box.
To calculate the left figure (point Y, Fig.1)
Measure the distance between A and B (1500mm) minus the distance between Y to B (730mm),
divide by the distance between A to B (1500mm) then multiply by the pixel width of the source
(1920).
1500mm-730mm = 770mm
(770mm÷ 1500mm) x 1920 pxels = 986 pixels
Enter 986 into the Left box for Region 2.
Alternatively, simply subtract the the previously calculated region width (934) from the known input
canvas width:
1920 - 934 = 986
