I have the Roku Stick which plugs directly into an MHL port. I have a TV without MHL (just normal HDMI) that I would like to try this on.
My understanding is that I would need to introduce 5v at 500mA and then I would have a compatible port. The HDMI spec says pin 18 is powered, is this port the powered for MHL as well?
Is there a detailed pinout available for MHL HDMI?
Is there a pinout for a Micro USB to HDMI cable for the MHL spec?
Should I be asking this somewhere else?
