From my HP Specter USB-C laptop I connected: 1. J5 Build JCA374 dock to add HDMI output (it also powers a laptop via USB-C ) 2. UGreen HDMI to VGA Converter with Audio connected to the HDMI output of Dock3. UGreen supplied a power cord for a standalone USB-A charging box to AC4. An old pair of computer speakers connected to AC power (via another standalone USB-A charging box)5. The stereo speaker input is connected to the UGreen.6 audio jack. An old male to male VGA cable connected to an old Samsung VGA7 display. Samsung screen on AC8. VGA male to UGreen female. Summary: Four AC power sources (screen, speakers, UGreen adapter, laptop), two self-powered USB-A chargers (leftovers from old phones, etc.) Samsung VGA screen - mute with jack - male VGA cable Old desktop stereo computer pair of speakers Everything works (for now; first day). Make sure you understand how to adapt to your computer's output. HDMI to VGA, not VGA to HDMI.
