Vertical field of view is not just less than
horizontal field of view, in terms of peripheral
vision, as the "standard eye" figures showed, but
it is also less than horizontal field of view
when you add in the effect of eye and head
movements. That same "standard eye" tells the
story about eye movement speed. Although you
made a mention of that once, you then
conveniently forgot to take it under
consideration this time.

Hence, your claim that human field of view is
more like 1:1 was way off base.

I am adamant about seeing a sensible standard
for next generation TVs get implemented,
rather than creating a standard based on
dogmatic political positions, on misunderstood
technical facts, or on misapplication of
solutions which might or might not make sense
for personal computers.

Luckily for me, it looks like common sense is
prevailing in the real world.
