Do you need help with the USB C to HDMI hub not working properly? One of the users shared his experience: “When I connect it to the USB C port on my laptop, it is able to recognize the device, but the monitor linked to the HDMI port on the hub does not work. The USB ports are normal, though. When I unplug and re-plug the HDMI cable that connects to the monitor, it ends up with no signal. The laptop’s display settings do not detect the second external monitor, even though it’s connected through the hub. I tested with another hub, but the issue remains the same. In Device Manager, my laptop still lists my monitor as ‘BillBoard Service.’”
