i have a 2017 vizio m55 purchased 2 months ago and a roku stick purchased 2 weeks ago. when i try to watch any channel i get a hdcp error 20. i've tried everything suggested by roku and nothing has worked. roku recognizes the tv as 1080p-1.4 hdcp. but the tv doesn't recognize roku. the stick gets really hot when plugged in the vizio, also, the stick works in our old sony.
what can i do?
