The whole thing is really screwy and the numbers never add up. For example, few digital stations broadcast a full resolution signal. In fact, they reduce that vertical resolution so that they can use the bandwidth to broadcast another SD channel at the same time. Just because something is produced at 1080x1920 doesn't mean it's anywhere near that resolution when it reaches your set. One PBS station I know broadcasts an SD channel together with an HD channel. To do this, they reduce the vertical resolution of the HD segment, sending out something like 1080 x 1200. Frankly, you can't really tell the difference.
There comes a point where you must stop worrying about whether your set displays each and every pixel, and concentrate on whether the picture looks fantastic or not.
