At the risk of stating the obvious:

Some of this discussion of HDTV implies that there will always be a need
for another generation of standards with even higher resolution.  That
isn't necessarily the case.  The human eye has limited resolution, and
higher resolution than that in the picture is literally useless, if you
are talking in terms of a "typical" screen size viewed from a "typical"
viewing distance.  Similarly, there must be an upper limit on useful
fidelity in color discrimination, beyond which the human eye just can't
see any improvement.

The analogy with audio is that a CD with frequency response out to 10
MHz would not sound better than one with frequency response out to 20
KHz, because the human ear can't hear the higher frequencies.

What we want in electronic products is high fidelity for both eye and
ear, but no more than that.  Unfortunately today's television and
computers are typically well below this threshold.
