Example: two screens in portrait

In this example we have two screens rotate clockwise as shown in the figure below.

Two screens rotated 90 degrees clockwise

The bezel between the screens depends on you Cell model. Let's assume the screens are MT550S models, then the bezel is about 65 pixels.

</multihead>

Above we created one window with two areas. Notice how bezel is taken into account when defining the second area origin (graphicslocation element). The dpi value (dots per inch) is for 55" model, corresponding value for 42" model is 52.44.

config.txt

NetBridge {
  host = "10.0.0.1"
  input-rotate = "90"
  input-translate = "1080 0"
}
NetBridge {
  host = "10.0.0.2"
  input-rotate = "90"
  input-translate = "2225 0"
}

In tracker configuration we define that the screens are rotated 90 degrees. The apparent extra 1080 translation is due to the way rotations are handled, see screens and tracker page for explanation.
