    Have a brand new macbook pro 13" with SL,
    hooked up to a vga 1680*1050, and it can never be detected at boot,
    the screen goes blue several times and nothing. I have to manually unplug and replug the display adapter to get it to detect. "detect monitors" does nothing either.
    The cable goes through a kvm but it's the same without.
    Also it's not an apple brand adapter.
    I've been told it's a common problem with vga, and it's coming from the macbook. Do you have any workaround?
    It's pretty annoying.

    Does the monitor have any other inputs (DVI or HDMI) or are you limited to VGA by the KVM?

    I also have hdmi.
    I didn't think it would support "non-TV" resolutions but tried it with another computer and it does.
    so I could try with hdmi adapter. would require to switch the source in the monitor + kvm but that's an idea (which will cost me again).
    any other idea?

    And will hdmi work at this resolution (1680*1050) for my late 2011 macbook 13"?
    any adapter will do? (don't care about sound)

    Yes, HDMI will work with 1680 x 1050 pixel.
    And any MDP > HDMI adapter will work.
