i just want a custom screensaver for my Hisense Roku Tv. i looked it up and it’s showing all the ways to but none of the things that it’s telling me to do isn’t an option on my mobile app or my tv. i have software update 10.0.0
Roku doesnt document this anywhere, but the "Custom screensaver" option is only available for 4K models.
Since you dont see that option for your Roku TV in the Roku remote app on your phone, thats a strong indication you dont have a 4K model.
You'd need to upgrade to a 4K model (doesnt have to be connected to a 4K TV or in 4K output mode) to use this feature.
