They commented on this during beta simply to say it's an issue with the TV settings. Unfortunately, not all TVs allow overscan to be turned off. However, the Vizio does and this is a better adjustment than if the game compensated for the television settings since it would make the picture fishbowl.

On the Vizio they don't call it overscan. You'll adjust your screen aspect ratio to "wide". This will turn off overscan and make your games fit better on the screen.
