Hi- I just bought a HP Spectre x360 11th gen (tigerlake 13-aw2004nr) upgrade to the f11 rev A bios. Unfortunately the upper displayport on the dock does not support a monitor. The lower displayport does function when plugged in. I’ve tried 4 separate displayport cables (2 of them new out of the packaging) in the 2 sockets, and consistently it’s the upper port that is malfunctioning. I’ve tried rebooting and unplugging/replugging and occasionally the upper displayport will light up but not at the full native resolution (1920x1200). I’m using 2 Dell U2412m monitors through the displayport connector.
I’ve also tried uninstalling the displayport install software, used the cleaning sw, but to no avail. Any help would be appreciated as this dock is perfect for what I want- if it just worked.
