  And yet my MBP refuses to output HDMI above 1920 for me :/

    Check your cable's version if you're using the latest MBP. Also, check if your output device can handle it. My dell u3011 can't handle even 2560x1600 through HDMI (which it has 2 for some reason).

  I own the Seiki 4K 50" The launch version of the retina MBP is artificially limited to, I believe 16hz. There are firmware hacks floating around to get this number to 24Hz (and above, IIRC).
