Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
About 30sec into turning on NBC during live broadcast the app zooms in. It can be on a commercial or live TV. No other station does this. I have tried deleting the app and restarting the tv. I do not have a display option that I can find to play with 720 or 1080 that I have seen in other post. I have a #TCL.
