Try unplugging the micro /hdmi connector at both ends and try reseating. After reseating, check the display for proper alignment. If it doesn't work, unplug the small micro connector end only from the top of the beagle board. This is the black board with the very small connector at the top. Do this while the game is powered on. Then insert the micro connector end in slowly and keep checking for display alignment. If you try this ten or fifteen times you will find a sweet spot where the display aligns right. I had this same issue out of box. The micro connector is so small it seams to be failing. Mine did and I had to replace the board. While waiting for the board, I messed around with this a lot and got it to align when hitting the sweet spot. Email me if you are still having issues and I can explain further.
Thanks
