What devices support 4K streaming?

4K streaming is supported on most modern 4K smart TVs from Samsung, LG, Sony, and TCL, as well as streaming devices like Apple TV 4K, Nvidia Shield, Roku Ultra, and Amazon Fire TV Stick 4K Max. Your internet connection must support at least 25 Mbps for Netflix 4K and 15–25 Mbps for other services. Make sure you also have the right subscription tier — Netflix requires the Premium plan, and Max requires the Ultimate plan for 4K content.
