New Install, dual display but not working correctly


New install of Manjaro with KDE Plasma. I have 2x 34in 3440x1440 144hz monitors. Only 1 of them is working and only at 60hz (I cannot choose any other refresh rate). The other monitor says it’s max resolution is 1024x768. These are identical monitors but different name brands (same hardware underneath). Any help to get this working is appreciated. I have attached some info below that might help.


PS. For whatever dumb reason I cannot post my system info, it thinks im posting a link.

Remove what looks like a link, then it should work.
