So... I'm feeling kind of silly here thinking this shouldn't be a big deal... but... I just changed the resolution of my display to 3840x2160 and figured it would 'just work' but it isn't. I took a look at my pinballx.ini file and saw that the default values for Monitor=1 was a whole lot less than 1920x1080, but it still worked when I was in 1920x1080, regardless I figured I would update it to be: WindowWidth=2160WindowHeight=3840 And that hasn't helped. I must be missing something, but I'm not sure where to look next. ini attached.PinballX.ini
