HP Recommended

We use HP Zbook G11 laptops with 100w HP G6 dock. We have an issue where our Samsung monitors(L24r65) are failing to be detected when 2 screens are plugged in via DisplayPort. The screens will continue to flick on and off and windows goes into a detection loop. The issue only occurs with this dock and monitors combo. 

It works fine using a single monitor or if we use the old G5 dock it works with dual monitors fine. Also works fine using a different model of monitors.
I have updated all firmware and drivers using the HP assistant with no joy.
I have tried with new cables Displayport cables.
Just wonder if anyone has seen this issue with Samsung monitors ?
