After all - thunderbolt devices should be interchangeable. I find it seriously ignorant by HP to indicate that this hardware mix is only supported by the business products, while I as a premium product (that's what HP call this) user is left in the dark. The HP products are wonderful, but the service/support quality is not up to that level. Instead I would prefer that HP took this seriously and tried to resolve the issue. Both my dockings are under warranty so I can have them returned to HP and purchase from a different vendor and share my HP experience with colleagues and friends and on communities like this. One other observation is that on Laptop 2 Thunderbolt control center does not register the G5 docking, but on laptop 1 the G2 docking is registered. Of course I cannot say for sure this driver is the source, but I can say for sure there are software/driver issues causing this. In both situations, the monitors connect when directly attached to the laptops. The same driver got installed during my travel, and when I got back home and docked my PC no external monitors connect via the docking. On laptop 2: fully functional before I went on a two week travel. got installed (verified by installation date in the updatelog). Later in the same morning Windows Update made a change, the NVIDA - Display - 27.

On laptop 1: fully functional until yesterday morning. This has to be due to some driver changes/Windows update. I have the same issue with more or less the same sequence of tried fixes.
