So I am setting up and it gives all these options...change to 720p Tv/ 1080p/ Change to 4K 30Hz/60 Hz....
I have tried several and none are working! Can someone please help me?
What is your tv brand and model number?
What model Roku, and what model number (check from Roku home page via Settings .. System.. About)?
How is Roku connected to tv? HDMI port? Directly or through an intermediate device such as an A/V receiver?
