[u-u] Extra monitor

[Evan Leibovitch]

The one you bought has HDMI on one side and USB-C on the other. The
majority of gear for sale has HDMI and USB-A, for which one of my A(socket)
to Micro-B OTG cables should work fine.

Still a bit of a clunky setup, but doable:

Video source -> HDMI-to-HDMI cable -> Capture device ->
USB-A(socket)-to-MicroB/OTG -> Android device
