Note: 
It is only compatible with computers with DP alt mode, not for USB-C smartphones (Except Samsung Galaxy Note 8 / S8 / S8 Plus) and tablets, as most of them work with MHL or SlimPort solution.
Supported resolutions and refresh rates of the adapter are entirely dependent on the USB-C host devices and connected display specifications. 
If your computer supports 4K@60Hz, while your monitor/TV only supports 4K@30Hz or 1080p, you can only output 4K@30Hz or 1080p rather than 4K@60Hz
MacBook 12” does not support 4K@60Hz output; it has a maximum output of 4K@30Hz.
An HDMI 2.0-compliant cable is required as utilizing the highest resolution 3840x2160@60Hz. HDMI 1.4/1.3 cables will likely result in a blank screen, digital noise, or display drop-offs.
For certain monitors may turn on and off every minute as connected with a long HDMI cable, for stable output, we highly recommend using a short HDMI cable within 5.9ft to connect your display.
