Mine is a 40" Samsung UN40KU6300 though Samsung appears to rev its model lineup frequently so they may have already released a successor to this model. It was a little difficult to confirm that it supported 4k@60hz with 4:4:4 chroma, but I relied on the experiences of some folks on an audio/video forum who confirmed that they had been able to run with those settings. Unfortunately, I don't remember the name of the forum or have it in my browsing history. I do wish manufacturers would make that information easier to come by though it's certainly a tiny minority of consumers that know or care about those kinds of specs.
