HP Recommended
U28 4K monitor

I can't get the USB C port of the monitor to output power to drive an external soundbar, or offer charge to anything needing a fraction of an amp.  The most annoying thing is that it works only occasionally.  Sometimes after randomly changing power management settings.  Sometimes after reset.  But invariably forgets after power down, and have to keep resetting or plug and unplug.  I wish I could tell what it is thinking.  I don't have a laptop plugged in.  Using the U28 as a monitor for a Roku stick inputting via HDMI, and interestingly powered by a USB A port which is not supposed to deliver power!
