but sharing about overall experience, I'm really happy with FP5. It works flawlessly with my 4k monitor and docking station. I can just plug it and use from mouse/keyboard/monitor. That's just awesome. FP4 was probably working similarly with FHD but I don't have any low resolution screen anymore, so I never tested it (I just can confirm that it couldn't drive 4k resolution).
I just hope FP7 will have fully fictional USB-C again (as FP6 allows only charging, no docking capabilities!!!)
