I am having troubles with the U1 and the 4K resolution. First of all, it seems to me all wrong that even though the U1 detects de capabilities of my 4K Tv, it doesn't automatically switch to the 4K resolution and it remains to 1080p. I mean, IMHO it doesn't make any sense, it should go for the best supported resolution. Second of all, when I manually force the 4k@60Hz resolution, I'm having big troubles with Kodi; the videos are not escalated and they remain to the original pixel size, this is, they are played in a tiny square of the total TV size. Do you have any suggestions?
