(this was a question about configuring a MBP with an HP Z27 monitor. Wrong forum. Deleted.)
I have this monitor too. I have several peripherals plugged into it, mostly external hard drives, but also a dymo printer and all seem to work fine. But I use the Logitech K380 keyboard, which is recommended by wirecutter and it has 3 Bluetooth radios. It works great between my and my wife’s MacBooks. I would recommend that to you. The keyboard is not very expensive.
