i-tec quatro ultra wide

[NetMajom]

Hello

I have:
* i-tec USB-C Quattro Display Docking Station with Power Delivery 85 W
* Dell P2417H (native resolution: 1920 × 1080)
* LG ULTRAWIDE (native resolution: 2560 × 1080)

I have a problem,, if I connect both of the display, the LG ultra wide is not "WIDE", its forcing the DELL resolution.

I have an Asus dock too. If I connect the LG ultra wide to my Asus Dock, its good, but its very frustrating, that I must use 2 docking station to it if I want to use the LG in Wide. I don't want to use both, because the I-tec docking station was very expensive, and I want to use only that.

Is there any solution to use both of my monitor with I-tec and the display link, or I must use 2 docking station if the monitors are not the same?
