Dual LG Ultrawide monitors on Thinkpad USB3.0 Pro Dock not displaying properly mac
 

As the title says, I have a Lenovo USB3.0 Pro Dock with two LG ultrawide 29UM68P monitors hooked up to it, one on displayport and one on DVI (with an adapter), and when both are plugged in I cannot display either at the right full 2560*1080 resolution no matter what I try, although with only one plugged in it works fine on displayport, is this a limitation of my dock or is there something I can do to fix this

For reference my dock's model number is the DK1522 by Lenovo

I figure this is a dock limitation?

Electronic page 24 (printed page 20) of the manual for your docking station --> https://download.lenovo.com/pccbbs/o...0h10911_en.pdf indicates that the maximum resolution supported when two video outputs are in use is 2048x1152. This means the limitation is the docking station hardware.
