Big Box Default Monitor

[Pakled]

I'm trying to run Big Box on my Windows 11 PC that has dual monitors and I'm just curious why Big Box (or even MAME launched from Launch Box) only seems to want to run on my secondary monitor instead of my primary monitor. Is there a setting somewhere that I can change or is this just normal behavior?

Using version 13.1

You can change the display used in Big Box options for Big Box. MAME has an INI file that can be altered as well. I would verify that the correct monitor is still marked as primary in Windows though. LaunchBox doesn't tell emulators/games what screen to run on and so they default open on the default monitor unless that emulator/game overwrites that setting (like MAME does)
