A:AnswerAll HDTVs have HDMI inputs. All external, smart streaming devices have HDMI. Plug it into HDMI1 and select HDMI1 with the menu.
FYI, it can be better to have smart devices outside all HDTVs in addition to built-in ones. Internal ones will have great features, but just their own. You can choose from dozens of external ones. Most importantly, you can update to newer external ones as the improve. That said, I like LG's internal HDTV smarts in addition to my Apple TV and Roku.
A:AnswerThe input power is AC 120V, 50/60Hz. This TV is manufactured for use in the US and does require 120VAC for optimal operation, however, the TV can withstand up to 240VAC with an adapter if needed. ^Daphane
