Fix USB to HDMI Device Not Detected on Windows
If a USB to HDMI adapter is not working, the most common reason is that the adapter’s USB graphics chip does not have the correct driver installed, so the key fixes are identifying the adapter chip, installing the proper driver, using a compatible high-speed USB port, checking Windows display settings, disabling USB selective suspend, and testing the adapter, cable, and monitor on another system.
