Notice:
1. 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 cable are entirely dependent on the USB-C host devices and connected display specifications. 
3. It needs 8-10 seconds for the signal to synchronize from computer with your monitor.
4. 4K resolution requires a 4K equipped source, and 4K display.
5. 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.
