"Plenty of Tube TVs don't display all of the content of the screen, as it's cut off at the sides. Companies usually consider this, and design their games/interfaces so the sides won't be cut off. An example of this is the phone in GTA IV. If you press up on the D-pad twice to bring up the phone's dial pad, you'll see that the phone is lifted far above the screen. This is so it won't be cut off on some TVs. Instead of seeing the phone suspended above the bottom of the screen, I see it sitting right on the edge of the screen, because my TV doesn't like displaying the edges."
my family own a CRT quite big tv and we have no problems with the screen not displaying stuff. we also have an adjust aspect ratio button for more tweaking.
so thus your statement is funny
