Display oversampling is GOOD. I have often used the following explanation of this as it relates to the differences between computer and TV displays. Computer displays have traditionally used Non-Nyquist filtered imagery (although modern graphics kernels in Mac OS-X and Windoze are beginning to use filtering to make images look more TV-like). Thus it is fair to say that a computer display is ALSO a TV display at half the resolution, when filtering is taken into consideration. The good news is that we can also use non-Nyquist filtering to present graphic, web content, etc. on modern progressive TV displays using lithographed technologies to accurately produce a raster of any given resolution.
