So I recently decided to try a Banana Pro ARM microcomputer to evaluate for my next project. I was disappointed that the unit output had overscan on my TV. Fortunately there is a simple fix for this annoying problem which the folks at LeMaker do not mention in their forums.
1) Press Source on your remote
2) Move down to your HDMI source and press Tools
3) Select Edit name
4) Scroll down to PC and select that one
Your screen goes blank for a second – and mission accomplished.
