No guarantee for "full", but I had a previous model and the G2 & G5 were able to connect the notebook to two monitors. 2x Ultra-Wide probably not, 1x Ultra-Wide and 1x normal should work.

I tested 2 different docking stations from HP today and both did not work. I will probably have to contact HP. Thanks anyway.

Should work in my opinion. But to be on the safe side, I would ask HP.
