Force BigBox to automatically switch primary displays on start and exit?

[JerichoGenerico]

Hi, all! I'm trying to do as the title suggests. I have two ultrawide displays and one standard display. I want to stream BigBox via Moonlight to my Apple TV, but with the ultrawide, it doesn't scale properly. I want to get BigBox to automatically change my primary display to the monitor of my choice so that everything works fine and loads up on that display. Is this doable?

The BigBox main display will only show on a single display (monitor/tv) that you set in the System Menu.  Also, the 'Primary Screen' you select to use has no direct ties to the "Main Display" you set in Windows.   It's either monitor #1 or monitor #2 (or #3 or #4 etc.).  There are no command-line parameters available to tell BigBox to start on a specific monitor.

To start BigBox on a specific display of your choosing (without launching it and changing it in the UI), you'd need to modify its settings file by changing the value for the Primary Screen, save and close, then start BigBox.

This could be 'automated' by creating a PowerShell Script, batch file, AutoHotkey script or other medium of your choosing that would do the change, save, then start BigBox.  Create 2 of them, one to start it on your Apple TV and another to start it on your ultrawide.

 

Regarding it not scaling properly on the ultrawide, that's out of my area of expertise.  But one thing I have read about is, if you have the displays' Scale (in Windows Display Settings) set to something other than 100%, you could experience something along those lines.
