HDMI Cables, possible physical adapters

Andy

Recently purchased a portable monitor with USB Type-C and Micro USB ports. Plan is to use as additional display on an HP 250G laptop. Laptop has full size HDMI and VGA ports for display. Connecting any of three USB's on Laptop to USB Type-C on monitor gives power, but no signal, and Windows 10 settings shows no options for multiple displays, except for option to detect a wireless display. Connecting an old VGA monitor to VGA on laptop, Windows 10 settings shows multiple display option. This all led me to dig further to find that laptop from factory is set up with only VGA and HDMI for external display. 1) Can I use a physical adapter to connect Laptop HDMI (or VGA) to Monitor USB Type-C successfully? 2) Am I able to switch a USB on Laptop in settings to output display? 3) Am I missing something with drivers? Thank you!

Does anyone know if this adapter is bidirectional?

Depending on the monitor, there may be drivers on the manufacturer's website you'll need to install to use it properly, so I would definitely check that first. You might be able to use an adapter? But normally USB HDMI adapters are designed to go from USB to HDMI, as opposed to from HDMI to USB.

There wouldn't be any special settings to enable to output video over USB, either your laptop supports it or it doesn't (most do).

That adapter, as far as I can find, is one-directional, from DisplayPort to HDMI only.
