I see a few posts here talking about 1080p output, and, going into the settings and changing between 720 and 1080. I got my brand new, latest version G-Box (running XBMC 12 Android though) yesterday and have been trying to find out how to get it output 1080.
The only setting I can find seems to be fixed at 720 even though it has the up/down arrows indicating it "should" be selectable. I have also ticked the box above this setting whic gives the option of "Auto output to best TV res".
I have the lates Samsung 7000 series TV which can certainly receive and output 1080p, however, I beleive the G-Box is outputting only 720.
