So I had to discover myself :D
Many thanks to HP After Sale support in Milan/Italy that replied to my questions.
Turns out that nobody cares to perform intra-vendors tests (makes sense) but they guaranteed me that according to Italian law if you order something (whatever) you have 14 days to give it back for any reason even you just changed your mind.
So I took my risk and bought both monitor and soudbar.
Works like a charm with MacBook Pro (15-inch, 2018), webcam as well and soundbar also.
The only bad news: you have only two USB-A ports, meaning:
- 1 for keyboard
- 1 for mouse
- ... where should I connect the soundbar that has a USB-A cable too?
Nevermind, luckly I had a small passive USB-HUB where I connected keyboard and mouse to release one port for the soundbar.
From my perspective HP could provide at least 4 USB-A ports instead of 2.
