I have a roku ultra connected to a Samsung smart tv. The auto display setting on the roku os does not properly detect the frame rate of the tv. It does detect I am using a proper hdmi cable however. The auto detect picks up a 30 frame rate for a 4k tv. This is where it get weird. An HDCP error message comes up only briefly when using the Amazon prime app and only for new content there. It then goes to content with no further problems. Old movies are no problem either. Etflix, Apple plus, HBO max, Hulu no problem. I will not even tell you the amount of time I put into to figure this out. And the cost for a new cable. The issue goes away if I change the display to 4k tv at 60. Is there a correction the the handshaking is done properly and automatically ? Thank you.
