I understand the frustration with this. If I use two VGA monitor ports, I can toggle the monitors any way I choose. If though, I want to use aa VGA as the primary (#1) monitor, and I use HDMI as the extended monitor, IT then becomes #1, and the app that I am running becomes useless. I need o be able to manipulate the video feed from the #1 monitor, the VGA, and display the chosen video on the HDMI monitor. Now, how do I manage this in Windows 10? I use use both monitors in my project.
