I have been waiting for a few weeks, but i finally got the cables and adapters i needed for the Motorola atrix lapdock. The main issue was finding an adapter to get from female micro hdmi to regular hdmi. I thought i was going to have to strip out the USB power cables so it didnt put 5v into the USB port the keyboard was going into but a forum post showed me i had a new board and surprise! It not only worked and let me type but it provided power to the raspberry too. Screen is really crisp. Works great. Added bonus is a powered 2 port USB dock. Really the perfect testing setup.
Now to see how long the built in battery will power the setup.
