Using an MHL Adapter is one of the easiest ways to connect your Samsung GALAXY NotePRO or GALAXY Note 10.1 (2014 Edition) with any other screen, projector or TV via HDMI.
We tested the Samsung HDMI-Adapter MHL 3.0 EE-HN910.
With our devices it worked with and without an aditional power source (not shipped with the adapter, you can use the one from your smartphone). We tested it with Full HD screens and different projectors. The order in which you connect the different cables didn’t matter either.
So it’s fairly simple: just connect the different cables and the screen mirroring starts automatically.
