For a desktop computer or laptop at the output, Type C is just an interface, like a shell, whose function depends on the internally supported protocols. Some Type C interfaces can only charge, some can only transmit data, and some can realize charging, data transmission, and video signal output at the same time. For the display at the output end, the same is true for having a Type C interface, which is not the same as having various functions. However, all monitors that use the Type C interface as their selling point can support video signal input and reverse charging.
