qingolden of course it can lol, it can at 4:4:4 as well. It was rated a 10 for pc monitor on rtings.com http://ca.rtings.com/tv/reviews/sony/x830c

I‘m having an issue with this adapter and the x830c as well using a GTX760, however when using just an hdmi cable, I can get 4k @ 60hz, but when I try this adapter only 30hz shows up. Not sure how 60hz shows up when using only an HDMI cable as I don’t recall the 760 having HDMI 2.0 which is why I ordered this adapter, but got the TV before receiving the adapter and seems to work without it, although mouse is a bit laggy at times which I thought was due to bandwidth issue, and thought this adapter would fix. Apparently Not.
