I am trying to change the screensaver on the Roku channel on my Samsung TV. I own two Roku sticks and a Roku Tv but my Samsung tv does not have the stick. Can I use my screensavers from my account on the Roku Channel?
If your Samsung is a smart TV that happens to have The Roku Channel as one of its apps that's nothing like having an actual Roku device. If you want to use your Roku screensavers on your Samsung TV you'll have to connect a Roku device to it and keep the TV on the input with the Roku.
