Using a Roku box on a Roku TV

I have a Sharp HDR Roku TV. Picture is okay. Got the 4K Roku Ultra box and hooked it up to the Roku TV. Picture is much better using the Roku box. Watched a Disney Plus HDR show on both. The box really improves the picture. 🙂https://kodi.software/ https://dltutuapp.com/tutuapp-download/
