My S1 Dual Screen extender is not working with my HP i3 Windows 10 in S mode. I've tried USBC to HDMI, USBC to USBC, USBC to USB, and I also have the screen plugged into an external plug providing power from the wall instead of my laptop. The screen shows S1 and then says "No Signal" and goes black, but only with the USBC to USB option. Can anyone tell me why this isn't working?
