It's a well known bug since the beginning. Somehow, sometimes the Box just simply forgets the 4K@60Hz setting and reverts to 1080p. As far as I know there's nothing you really could do about it. Its up to Himedia to fix this, but as I have read the upcoming fw changelog, there's still no sight for the fix.
