The Monitors tab
Windows uses a strange algorithm to number the monitors: the first monitor ever connected to the computer is monitor 1, the next monitor connected is 2 and so on.
BioniX Background Switcher allows you to change that order so you can re-assign numbers to the monitors based on their physical order. So the monitor order shown in BioniX Background Switcher CAN BE different than the order shown in Windows Screen Resolution panel.
To change the order of the monitors just click the spin box in each monitor (see image below). Press Apply to apply changes.
If you press the Refresh button BioniX Background Switcher will reread the monitor configuration from Windows (you will loose change made to the spin boxes).
Clone wallpaper on all monitors
Each monitor will show the same wallpaper. The wallpaper will be stretched independently to fit to each monitor.
A different wallpaper will be set to each monitor.
The same wallpaper (if large enough) will be stretched across multiple monitors.
