USB Type-C Male. HDMI output. Number of displays supported: 1. 3840 x 2160 pixels 60 Hz. Black. The Plugable USBC-HDMI adapter enables an HDMI 2.0 output at resolutions up to 3840×2160@60Hz (4K/UHD) from systems which support “DisplayPort Alternate Mode” (Alt Mode) via USB-C such as the Apple 12″ Retina MacBook 2015 / 2016, the Chromebook Pixel [2] 2015, Lenovo P50/P70, XPS 13 / 15, and many more upcoming systems based on the Intel Skylake/Alpine Ridge platform.. Alt Mode adapters allow you to add an additional display output easily and inexpensively on supported systems. Since “DisplayPort Alternate Mode” is a direct pipeline to your graphics processor via special functionality introduced in USB 3.1, there is no performance penalty to using the adapter; the attached display should be just as responsive and functional as if it were connected to a video port directly attached to your system’s motherboard.. Please note: the 12″ Retina MacBook does not support 4K@60Hz output, it has a maximum output of 4K@30Hz. Supported resolutions and refresh rates of the adapter are entirely dependent on the host device and attached display specifications.. Performance. USB connector type. USB Type-C.
