HDMI cables can be directional: I bought a portable monitor today with a Micro HDMI input and my Micro HDMI to HDMI cable doesn't work on it. The computer detects it but no video signal gets to the monitor. It only works when the Micro HDMI end is the
source, which is typically the case when attaching something like a camera to a TV. It doesn't work when the Micro HDMI end is the
sink.
