I bought a cheap, low-end HDTV television, and just noticed that the actual resolution of the set is 1360x768. That's just like wide VGA.
To get the 1080P vertical resolution, the tv does some anti-aliasing. You can see this when you boost the signal to 1920x1080, when the pixels get ugly, and when you move windows, the vertical lines change appearance and lightness.
Now the TV seems like a bigger ripoff than ever, because 1080P computer monitors are really cheap, like $150, and have real 1080 lines of vertical pixels.
