I have a latitude 7390 with Intel UHD card connected to a TB16 (K16A) dock. I have two 27 inches screen, a HP Envy 27S connect to mDP, and a Dell U2718Q connected to HDMI.

I can get 3840x2160 or 2560x1440 on the HP screen and only 1920x1080 at 30Hz on the Dell screen which looks really bad, how is it and is there anything I can do about it?
