[WORKAROUND] AMS2 - Incompatibility with Quad Monitor Setups

i would blame it on Nvidia for sure

 

I'm with AMD but it's the same thing, and then it doesn't matter who is the culprit, I have a problem that I would like to resolve but I've tried everything and it's frustrating, and if anyone has any ideas to make my 4th monitor work I'm interested

 

Sounds like AMS2 really doesn't work well with multi-monitor setup. I have some different issue but the core seems to be the same...
Desktop resolution limited very low with Quest3

 

Well, on the one hand, good to see this thread got some traction and I wasn't the only one with problems...
On the other hand, having seen a video from SimRacing604 on some improvements on the topic of the triple screen options committing changes in the menu as part of one of the 1.6 updates I was curious
Sadly, issues persist - if I enable my 4th (top) display at any time (before AMS2 launches or while it's open) then the app shrinks itself down to a single screen (while maintaining the triple screen aspect ratio/resolution in-game so everything is squished) - given I regularly use my 4th screen for other apps (Discord, browser windows etc.) to see them in the background while driving this is a frustrating obstacle that I hope is core to the Madness Engine (which sounds vaguely right to me from my recollections with Project CARS 2)

 

Have just been able to load in and get this far also, the only thing I'd changed since last trying and posting about the issue is changing the "ForceTripleScreen" value in the XML file to true

Edit: And exactly the same thing for me as t1ny, after closing the game and restarting it while my 4th monitor was active, AMS2 only opened on a single screen - the XML file for TripleScreenSettings was edited after I re-launched the game and it changed the "AllowTripleScreen" value to false automatically

 

same for me my 4th monitor is no longer possible to use on Ams2, I have the same problem as you and there is no solution until Reiza rewrites his script, we are stuck and it's a shame
