The USB3C-HDV024K is a USB-C display adapter that allows you to connect one of three displays to your USB-C port by using DisplayPort Alt-mode (referred to as DP Alt mode). This adapter is very portable and eliminates the need to carry multiple adapters. Note: If two or three of the outputs are connected, then only one output can receive the input signal, the priority sequence is: VGA, DVI, HDMI.
