The firmware recognizes the native graphic driver and will apply the screens automatically by default.
Define two or more monitors:
- Go to User Interface > Display in the structure tree.
- Select 2 (or more) under Number of screens.
A yellow and a white rectangle for the primary and secondary screens will be shown:
Autodetect Resolution: The operating system reads out the EDID (Extended Display Identification Data) of the monitors through DDC (Display Data Channel). With these data, the correct resolution for the monitors can be recognized and set.
Automatic Monitor: Automatic assignment of the screen to the graphic connector (monitor).
- Drag and drop the rectangles to position the screens.
By default, the primary screen is the one where the taskbar is situated.If the Autodetect resolution is not available check the DDC Option under User interface > Display > Options. The DDC Option must be enabled (default setting).
