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.
We have a roku 4 Ultra and the NBC and FOX apps are having Zoom In issues. We have tried switching HDMI outlets, manually changing the screen size on the Samsung TV, manually changing the settings on the Roku from auto detection to 1080, and the channels still zoom in.
I'm having the same issue with a TCL tv with Roku built in so it can't be the HDMI issue. I've tried changing the picture size from Auto and it still zooms in after a few seconds. On the recorded programs it's not an issue, just live TV.
