This is a USB-C/Thunderbolt 3 to High Resolution (4K@60Hz,6.6 FT/2M )HDMI Video Cable for MacBook Pro 2018/2017/2016, iPad Pro/MacBook Air 2018,Galaxy S9/S8, Surface Book 2,Other USB Type-C Devices.Works great with my galaxy note 8. Not sure on 4k output because my TV is older and only 720i, but it looks pretty good. The hdmi side of the plug is a bit big to plug into different devices. I tried to plug in to my xbox one and it didn't want to stay plugged in. #RankBoosterReview ii. #Sponsored iii. #innomax
