Unfortunately it is not powerful enough to play 4k videos without shudder/stutter with every codec. It could not handle mpc-hc or vlc media player codecs, works good only with windows media player however wmp is not user friendly, does not have any advanced options for sound and subtitle/caption and does not meet my requirements. Tried everything, installed 2x4gb dual ram, a ssd, a certified premium hdmi cable but could not succeed to have smooth picture. Even mouse movement at 4k resolution is choppy and very annoying. It may be fixed with driver updates in the future because of its hardware acceleration capabilities however until then it is useless as a htpc for 4k. I returned it and upgraded to NUC7i3BNH and i am very satisfied with now.
