The over width for the screen has now made it impossible to find any data on the left and top of the screen, and therefore using Roku channels have become a challenge to use.
The non-Roku local viewing does not have the have this problem. Please advise.
Look for a setting in your TV or a button on your TV's remote for picture size, aspect ratio, zoom, or anything else that refers to the screen. There's not a Roku setting that would affect this.
