    4K works, but capped at 30hz (can't achieve 60hz)

    I picked up this adapter in an attempt to achieve full 4K res from my 4K Samsung TV to my MacBook Pro Retina.
    The Belkin adapter was able to convert the HDMI signal to 4K, but it was capped at 30hz (so screen movements looked choppy).

    I tried everything I could (adjusting display resolutions, using SwitchResX, different Thunderbolt ports, etc...), but I was unable to get anything higher than 30hz.

    The adapter also felt warm to the touch when in use.

    - Macbook Pro Retina -> Samsung 4K TV
    - 4K works, but 30hz only
    - Can't go higher than 30hz
    - Adapter felt warm/hot when in use

    I plugged into a 1080p TV to give a presentation. I configured the TV as an external display and used my MacBook Air's display for presenter tools. This was my first time using this adapter and things did not go smoothly. At some point the screen dimensions seemed to get out of wack and parts of the desktop displayed on the TV bled into my MBA's screen. At one point I disconnected the adapter, but the problem did not reset itself. My MBA's desktop was still shifted over by the area that had previously displayed part of the external desktop. This same MBA normally drives a Thunderbolt display so I don't believe that it was just a matter of its graphics capabilities maxing out. I'll give this adapter another try next time I have a chance, but I'm not confident that I won't have similar results.
