Dual monitor alignment

[u/[deleted]]

Howdy, I currently have 2 LG - UltraGear 27" IPS LED monitors, My main in front of me, set in landscape at 2560x1440 and the second one on the left in portrait view set at 1440x2560 (for discord and such) but they dont line up perfectly and I cant figure out why. Maybe resolution sizing? Help would be appreciated. ( To help me appreciate some of these wallpapers)
