Apparently it's a default setting called "overscan" within advanced settings of the Insignia tv. Turn it off and it should work (I fixed it on my own tv about 5 minutes ago)
It's not working I have a Roku TV and I have a Roku box my Roku box is zoomed in and there's no way to fix it. I've tried to plug it I've tried turning it off I've tried factory reset nothing is working.
Curiousmonkey3, Roku devices have no settings to zoom, but many TVs do. Check your TVs settings for zoom, or picture size, or aspect ratio, or anything else that may have something to do with it.
