whats the best way to use 2 monitors?

[abispac]

I’ve got two R5 430 cards and I’m trying to build my last cab with a dual-screen setup. The main goal is to play Punch-Out!! and Super Punch-Out!! properly, but I’d also like to use the second monitor as a marquee display for most other games.

Here’s where I’m stuck:

EmuDrivers detects both cards.
I installed the drivers and Windows 11 recognizes both cards.
I’m running the latest GroovyMAME.
In VMMaker, I see a bunch of AMD monitors listed, but they all appear as enabled no matter which one I choose.
In Windows, I only see my current LCD monitor and one CRT monitor (eventually I’ll remove the LCD once everything is working).
I’ve searched online but couldn’t find any guides that cover this setup on Windows 11. Does anyone know the proper way to get this working with GroovyMAME? Any advice would be greatly appreciated.

Thanks!
