You can set up any Video-Wall, as long as screens are mounted in landscape or portrait orientation. So, you can create video-walls like this one:

If you wanted to do bezel compensation or set up an asymmetric video-wall, you need to measure actual distances between the screens’ viewable areas. 

Use the Test Card above and make sure it covers the whole area of the screens. So, in the general case of an asymmetric video-wall, you should have something like this to do the measurements.

Remember: The Test Card should cover the whole area of the screen. Make any changes required to have a similar result to the one above.

The Test Card has a white line exactly on the edges of the viewable area of the screen. Use that to make your measurements.

A fundamental note: make sure these measurements are as precise as possible, or else you risk misalignment and will have to do it all over again. Measure in millimeters or use 1/16ths or 1/32nds of an inch. It would help if you were as precise as possible.

For each screen:

Measure the distance from the top-edge white line of the top-most screen to the screen’s top-edge white line. Let’s call this SCREEN_TOP.

e.g., The top-edge white line of the top-most screen (TV3) to the top-edge white line of each screen.

Measure the distance from the left-edge white line of the left-most screen to the screen’s left-edge white line. Let’s call this SCREEN_LEFT.

e.g., The left-edge white line of the left-most screen (TV1) to the left-edge white line of each screen.

Measure the distance from the top-edge white line of the screen to the bottom-edge white line. Let’s call this SCREEN_HEIGHT.

Download or copy this Google Spreadsheet.

  • Punch in the above numbers, and it will do the math for you. Then go directly to the final step below.
  • Go into your Portal and do the following for each Video Stream feed matching each Screen:
    • Set the “Top” cropping percentage as calculated by the spreadsheet.
    • Set the “Left” cropping percentage as calculated by the spreadsheet.
    • Set the “Bottom” cropping percentage as calculated by the spreadsheet.
    • Set the “Right” cropping percentage as calculated by the spreadsheet.

The result would be something like this:
