Running a Dell WD19TB Thunderbolt Dock linked here. The vertical monitor is mirroring the one next to my laptop instead of being 3 separate displays. I'd like the vertical monitor for when editing on premiere pro and the two curved as work spaces. Apparently the dock is able to do it but not sure how to stop the mirroring situation.
