Video Wall Calibration

Video Wall Calibration

DISPLAX Connect version 3.7.0 and later includes the feature, Video Wall Calibration - added to our existing calibration modes to ease the process of calibrating multiple TILEs in a videowall or table, at once.

DISPLAX Connect will detect all TILES connected to the PC, and instantly set the calibration areas automatically. All connected TILEs are displayed in the left panel in DISPLAX Connect.


The following example has 4 Tiles in Portrait orientation, positioned as 4 vertical columns in 1 horizontal row.




  • Launch DISPLAX Connect
  • Click on the CALIBRATION Menu
  • Select Video Wall



  • A Config Video Wall option will appear, select the appropriate videowall matrix. Our example is 4x1
  • Click on the CALIBRATE button



  • All the TILES calibration area will be automatically filled




  • Due to different resolutions and aspect ratios, the green rectangles indicating the calibration areas may not be correctly positioned. In this case they can be adjusted manually using the controls on the rectangle vertices and corners



  1. Rotate rectangle
  2. Adjust size vertically
  3. Adjust size diagonally
  4. Move the entire rectangle
  5. Adjust size horizontally


  • Ensure the rectangles all fit inside each TILE, leaving a black border of 3-5cm around each.
  • Press Space to start calibration
Note: The rectangles are not attributed to specific TILEs, simply ensure the size is correct and the rectangle is within the TILE's active area as illustrated above during adjustment.
It is highly recommended not to fill the entire TILE display area with the green rectangles, so as to access the Calibration targets correctly.

The calibration targets will appear in one TILE at a time (4 per TILE). Place your finger on the center of each target until the green circle completes itself, then move to the next target.



Once you complete the last TILE, the calibration process will be complete and you can now use all TILEs as one big touch screen.
