We got a free Flex from Xfinity and I'm trying to connect it to my RokuTV. When I plug it into HDMI 1 or 2, nothing happens. It seems like I need to change the source on the RokuTV but I don't know how. Does the Xfinity Flex even work with a RokuTV? If so, how do you get it to work?
I forget exactly where it is in the Settings, but look for "TV inputs" and make sure HDMI 1 and/or 2 are added. It will add an icon(s) to the Home Screen to switch to the different inputs.
