Are you sure the overscan fix is set to "on"? I set it to on and left at it default value and it made a huge difference. If it's on and still not making a difference I would check your tv settings. Whenever Ouya officially get around to fixing overscan I would imagine it would be a more user friendly version of this fix.

Here are manual commands for the fix:


adb shell setprop persist.sys.hdmi.overscan 1
adb shell setprop persist.sys.hdmi.overscan.val [0.0 - 0.2]
or sometimes the automatic mode works as well:
adb shell setprop persist.sys.hdmi.overscan auto
