A:Answer The tv auto detects the video coming from a source and formats how it is being sent.
If you have a provider like comcat or directv, you need to change the settings there using box. It's using referred to as VIDEO that provides how the picture is formatted and displayed. That is where you need to make the change.
Not knowing where the news source is coming from (provider, app, antenna), I cant provide further details.
Hope this helps
