kphs, I have it running on a late 2013 MBP Retina 15″ and a mid 2015 MBP Retina 15″, if you are sure that you tv has a hdmi port capable of 4k@60hz and you also used switchresx with the settings from above, you should change your hdmi cable till you get one capable of 4k@60hz, I had tried with 3 cables before I finally got one capable. Choose one thick and with a textile protective coating. Hope this helps.
