Used to connect a B07YX5NKK2 Lenovo ThinkVision M14 monitor to my B084ZYR923 single port Apple Retina MacBook. This cable transfers power from the monitor to the MacBook and absolutely perfectly routes the DisplayPort alt-mode signals from the laptop to the monitor. It's nice and short, about 9 inches long! I use this cable because the M14 comes with a 3ft cable which most of the time only gets in the way when the monitor is used next to the laptop.
