I have always had problems with my xbox fitting the screen of my TV. But the only two out of four provided aspect ratios that my TV has are either 1. Barely to large for the xbox. Or 2 so large that I can't even see half the screen. This is largely because of how old my tv is but I think that the xbox one could provide some on system calibration so its not all left up to the tv. Something similar to what kind be found ingame where you can adjust the screen via slider.
