Does the Apple miniDVI-to-DVI adapter, going from DVI-D to DVI-D or DVI-D to HDMI, result in a loss of quality (due to the intermediate step of using an adapter as opposed to directly going from miniDVI to DVI or miniDVI to HDMI)?

Thanks

    Logic would say you would.
    If it is noticeable or not ???

    Nope. Digital signals don't work that way. They pretty much either
    work perfectly or fail completely. There's no "gradual deterioration"
    of video quality; a cable/adapter either works ...or it doesn't.

    There is some loss in signal loss, test it.

    Yep, cables/connectors will always cause some loss in signal strength,
    but cables and connectors are unavoidable (unless you can suggest a
    magical method for connecting to an external monitor without them).

    However, in the digital domain, signal strength has ZERO EFFECT on
    data quality. If the 1's and 0's reach their destination in recognizable
    form, the cable +works perfectly+. If they don't, the cable +fails totally+.

    BTW, there's no "signal conversion" in going from MiniDVI to DVI or
    HDMI; the "adapter" is entirely passive and simply provides electrical
    connections to the appropriate connector pins.

    ...in the binary world, the only grading system is "pass/fail",

    My assertion was that there is greater chance for error with adapters. I have passed the sixth grade but thanks for the copy paste answer.

    My assertion is that there is ZERO chance of errors without a
    MiniDVI-to-<whatever> adapter -- because NO ONE makes
    cables that plug directly into a MiniDVI. If you don't make a
    connection, it can never fail.

    So yes, there's a "greater chance of errors" -- compared to
    an entirely imaginary cable that never existed. (But only if
    you're running so close to the raggety edge that an extra
    10 milliohms contact resistance will break the camel's back.)
