It is onLY compatible with computers with DP Alt Mode, not for USB-C smartphones (Except Samsung Galaxy S8 / S8 Plus) and tablets, as most of them work with MHL or Slimport solution. 2. Supported resolutions and refresh rates of the adapter are entirely dependent on the USB-C host devices and connected display specifications. 3. 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. 4. MacBook 12” does not support 4K@60Hz output; It has a maximum output of 4K@30Hz. 5. 4K video resolution requires a 4k capable computer video source, mini DP cable, and output display. 6. For certain monitors may turn on and off every minute as connected with a long mini displayport cable, we highly recommend using a short mini displayport cable within 5.9ft to connect your display for stable output.
