  Yeah I don’t think there’s a 5V pin for VGA.

  I think if we had the scenario where we had a higher voltage than needed, we could have a toasty voltage regulator making something happen, but going the other way would need boost circuit unlikely to exist in these parts, in my understanding

    There is! It’s pin #9

      Ah my memory failed me then! Thanks for the correction, I guess this is technically possible then!

  Doesn’t matter. The VGA to HDMI adapter is active, not passive, so it matters if HDMI has a 5v rail, not VGA

    If, hypothetically, VGA didn’t have a 5v rail then how would power get from the monitor to the HDMI adapter. It would absolutely have to be a part of the spec.

      It doesn’t need to be 5v. An active adapter can have a buck converter.

      In reality active HDMI adapters get powered by the HDMI device though, not the VGA monitor, so it’s a moot point anyways

      If the vga/hdmi adapter is active then this abomination could actually pass display information provided you had a micro-usb device that supported display out over usb (idk if there is such a thing and if so it probably doesn’t work all that well but still)
