    • Apparently, HDMI / Ethernet is actually standardized, but since it can only do 100baseT, it can’t be what those switches are doing.

    • I guess the reason for this is that HDMI cables are easily available, available in the lengths that they want, and tested for the data throughput that they need. The more I think about it, the more obvious it seems that HDMI cables would work great for network patching, except if the HDMI Forum tried to sue you for it.

      Yes, I knew about this, I’ll add it to the article to avoid any confusion.

      I don’t really agree. Ethernet cables have a clip so they don’t fall off easily. DisplayPort or DVI would have been better choices.

        From a pure cable perspective, why is DisplayPort better than HDMI? Their cables have a similar profile unless I’m missing something.

          Because full-sized DisplayPort cables have a clip that keeps them from falling off.

            Huh, looks like you’re right. TIL. Can’t believe I hadn’t noticed that before. DisplayPort cables tends to be plug-in-and-forget-about-it-for-months for me.

              God I hate those clips so much. Every monitor I have has the ports hidden behind a plastic “lip” that I guess is supposed to shield them from dust or something, and just makes the tiny buttons on most DP cables nigh on impossible to press with the apparently-oversized meat-sausages I call fingers :(

        ULX3S, an open-source FPGA dev board, calls the connector GPDI (General Purpose Differential Interface). There used to be sample code for outputting video to a HDMI-capable display over it, but the code has been taken down.

          Display cables are the highest bandwidth cables in everyday use. So not much surprise that they are being (mis)used by networking equipment for their availability and bandwidth.
