I see a warning message about multiple monitors when using the SC Recorder

Download Surgeon's SC Recorder can only work when a single monitor is connected to your machine.
If you have more than one monitor, the SC Recorder doesn't know which monitor is being used, that is why
is shows this warning message.  

Windows 10 gives you the ability to create multiple desktops. If you create a different desktop for each monitor you have
connected to our computer that should solve the problem. However, if you have more than one monitor associated with the
same desktop then you will again see the same error message.

Here is a link to an article about creating multiple desktops.
