I really like this unit except for 3 negatives,  1. it has a cooling fan so it makes noise next to my bed.  2. it is not upgradable as per ASUS help chat.  3. it will not play 4K compressed videos well if at all.  I am using this to drive two Sony 4K monitors one 65 inch and the other 85 inch.  The hardware is much too old now and technology has made it obsolete in only a few years so now I am waiting for the up coming 12 and 13 generation processers to replace it.
