    So I bought a new BenQ monitor that can display 1920x1080, and have hooked it up to my 13" MBP via HDMI.

    I can get it to display at 720, which looks horrible.

    In system prefs, under the display tab, neither 1080i nor 1080p are available as options.

    Once I tried SwitchResX and turned on 1080i, I get an intense shaky-blurriness on the monitor (yet when I turn on the monitor's native menu, it displays just fine).

    When I turn on 1080p, I get mostly white noise with the occasional flicker of background. Again, native menu displays just fine.

    So - can my MBP produce a 1080p signal? Is it possibly a problem with my cable or connector? Have I missed something completely?

    Do you have another monitor or TV that supports 1080p which you could use to test the adapter?

    Figured it out. It was a cable issue. Thanks.
