Using Dual 4k Monitors via ultra slim docking only supports 4k in one monitor and 1080 in other.

I have 2 4k Monitors that I've connected to my laptop via ultra slim docking station, and it all detects fine and all that is good, however the problem is I can only get 3840x2160 resolution in one of the monitor and not both. In the 2nd monitor I only get 1920x1080 resolution which defeats the purpose of having 2 4K monitors for a better experience.

I've tried all settings, dock firmware upgrades but nothing has worked out to give me 3840x2160 resolution in both monitors.

I have this same issue. Did you ever resolve it?

I was able to resovle this by switching the Refresh rate for both monitors to 29 hz. Since the refresh rate is lower it does lag a bit when you are moving mouse or at times watching a video, however you get used to it after few days.

Does anyone know if this is a limitation of the hardware or has HP resolved it with a firmware update?
