6. Select the target monitor for the MP Controller

The first time you load the MP Host plugin, it will be displayed on your main monitor. 

You need to select the target monitor from the big window of the MP Host plugin.

Right click anywhere on the main black area of the big window and from the menu under Monitor, select the target monitor which will be the last monitor in the list.

When you right click anywhere on the empty area of the main window the following menu will show up as shown in this video

The same principle applies to other MP Controller plugins or apps. Each app has it's own properties file in the /MP/Host folder where it stores the selected target monitor.

Troubleshooting the right click:

If you don't see the menu when you right click, see the following suggestions:

1. On the Mac, using a Mac mouse, ensure you have set the Mouse button Secondary Click to "Click on Right Side"

If you are using an Apple Magic Mouse, you have to press the Control key and hold it while you right click to generate the right mouse click.

2.  Check the arrangement of your displays. It is adviced to place the mp controller left ofr theright of your main display, on Mac or Windows. 

3. Try using a mouse that has a right click button instead.

4. Additionally, if you installed UPDD you can right click by touch and hold on the main area of the MP Host plugin.
