Hi, so I have a Onn 4K box connected to a Roku TV… I have upgraded my TV to a new TV but for the life of me I can’t figure out how to change the TV models on the Onn 4K box. The only thing that I can think of is to do a factory reset but I don’t want to … too many apps to re install. Any help would be much appreciated 
Ok, please forgive me, but why would you need to change the TV on your Streamer? You plug the HDMI out from your streamer and into the TV eARC or ARC, which for most is the HDMI one, then set your TV to the HDMI input you chose, fire up the streamer and start watching the TV. The device homescreen will be displayed on your TV and then you just start clicking your way around. You can access the device settings for advanced configurations. You may need to go into the Display & Sounds to make the most changes like Power control. Going into the Remotes & accessories config may also be needed.

Oh you were talking about setting up your onn remote (or other) to work with the new tv since it was programmed for the Roku tv before.
Gotcha.

Since you’re talking about the 4k Onn, I’ve just added a Hub, external storage and keyboard Usb dongle to mine. All work fine. The keyboard works just fine in bluetooth mode as well. The mouse, everything. It makes a few things so much easier.
