    So using the HDMI port will not give 60Hz with a 4K display, but using the thunderbolt port will.

    If the display has an HDMI 2.0 input, which supports 60Hz, would a thunderbolt to HDMI 2.0 adapter/cable work? Any out there you guys recommend?

    If the display has HDMI 2.0 it will also likely have a DP port and you can use a miniDP to DP cable which will be significantly cheaper (due to DP being around for much longer than HDMI 2.0).

    Yes, that should work. Except it's called Mini DisplayPort to HDMI 2.0, not Thunderbolt to HDMI 2.0.

    But DisplayPort is preferable if you have the option.

    It's a 4K TV, so it only has the HDMI 2.0 input, no display port, unfortunately.

    I am using adapter from UPTab
    Using it with MBP 13" late 2015 and MBP 13" late 2013, both works at 60Hz with a Samsung 40" 4K TV.

    I'm running into some issues, maybe you guys can help.

    OSX is recognizing the Samsung TV (55KU6300) as 7680 x 4050. Under scaled options, the correct resolution is not listed 3840x2160. If I launch an app like Display Menu, I can select the correct resolution.

    I tried launching a game to see if the same thing would happen, and one game saw the TV as 4096x2160, and another recognized it correctly as 3840x2160. This happened even when using the Display Menu app and manually picking 3840x2160.

    Any thoughts?
