I've got a Roku attached to a Vizio TV in my office. Couldn't find any settings on either the Roku or TV menu's that made a difference. My wife stumbled upon a button on the remote that actually controlled the screens zoom level (Wide, Narrow, Zoom, etc...) and that ultimately was the fix. It also made sense as to why the problem popped up in the first place because the kids were probably pushing buttons. Frustrating that there is a physical button on the remote that controls a setting, but we couldn't find the same setting in the menu... Hope this helps somebody.
