Reboot the box and hold the button with the 3 lines and 3 dots
This is for KOOLKATK: I have been having this problem:" unsupported mode". and I believe that is why I am having these hiccups. By reading this post, XBMC BG said by holding the button with the 3 lines and the 3 dots. how do you do that? I know how to get to bios but 2 lines and 3 dots. I wjsh I could get my resolution corrected. Please can you explain it to me? how to do it.
