I can confidently tell you that it is not the HDMI cable. I have tried several hubs until I found one that actually works with the same monitor and cable setup. I have been using Dex since S8, and never was able to get it working with that on 2k (edit: Dex worked fine but only 1080p) until my USB hub got lost/stolen and got the Zedela one. I am also told the expensive Microsoft Hub works for sure, and is my next purchase when this corona business is done and finances arent a scare.
