This Type-C male to Mini DisplayPort male cable supports resolutions of Ultra HD 4K x 2K at 60Hz. It is typically used to connect a Type-C source (PC, Laptop, Mac Computer, Mac Laptop, etc) to a Mini DisplayPort display (monitors, etc). This cable is uni-directional, therefore it willonly work from a Type-C source to a Mini DisplayPort display and not in the reversedirection.
