    I am buying a new 2015 MacBook Pro which has the Intel Iris Graphics 6100 that supports 4K resolution at 60Hz on external display. I'm actually waiting for the 2015 15" MacBook Pro, but I assume it will have >= the graphics capabilities as the newly-released 2015 13" MacBook Pro.

    I've only read about 4K computer monitors supporting 60Hz, but I've seen no mention of 4K TVs. Is it reasonable to expect the 2015 MacBook Pro to also output 4K at 60Hz to TVs [which support it], as well?

    Yes, it will do that.

    Because I tested it with my Sharp PN-K322B.

    Note: Your TV must have an mDP/DP 1.2 port and you've to use an mDP/DP 1.2 cable.

    AFAIK the problem is there are no DP 1.2 to HDMI 2.0 adapters available right now and Broadwell only supports HDMI 1.4. So as mentioned above you must have a TV with DP input. Supposedly there should be DP to HDMI 2.0 adapters available later this year.

    Not at 60 Hz, I'm afraid.
