So I been considering of getting a 4k tv for 4k gaming on pc. The KS model line is pretty decent for pc gaming @4k but now they are being phased out and replaced by the new MU model line. So my question is the MU line just as good as the older KS line? It's still 4k @ 60Hz I know that much. The guy at BB couldn't tell me what is different on them. Anyone get one yet and try it out? Curious for a impartial review. Thanks in advance.
