I don't know how many pins my cable has, and never knew there was any such difference. It's the one that came with the monitor. I chalked it up to a driver issue, since the exact same hardware works great on Linux. I also have a separate, random Chinese dock off Amazon, which I couldn't get to work under Windows with that particular laptop. It works fine under Linux on that same laptop, and also works fine under Windows with a different, AMD-based laptop. I haven't tried it in a while, but right after it started working with the HP dock, this particular dock was still not working at all.
