Thanks for the explanation - I appreciate it.
I am still a little confused about why different Macs
give different readings with the same monitors -
72 ppi with the 6360, and 72.001 ppi with the 8600
(no adapters).
Could it be that the 8600 hardware is merely more
precise in how it interprets such data? In other
words, maybe the 8600 reports what it believes to be
the exact value, whereas the 6360 just rounded stuff
off to the nearest whole number? (I guess *that*
wouldn't be surprising ;) in general)
But, this 8600 has, shall we say, some "issues" with
monitors in general, which leads me to be a bit
suspicious of the 8600 itself. I suspect that
something's toast in there, that's what I think - both
the bus speed and the processor speed are
ever-so-slightly above specs, which seems a bit
suspicuous, doesn't it? like (speculation follows)
maybe some previous owner turned it up, had problems
or partially fried something on the motherboard,
turned it back down to sell the thing quick before
something else went out, but didn't get it *quite*
back to factory specs?? Anyway, the 6360 never behaved
like this, *whether* using two monitors or *not* (yes,
I had dual monitors on the 6360 - it was great - made
the thing actually usable). I was hoping that the
72.001 thing maybe was a valuable clue to eventually
solving the other problems.
Maybe it's unrelated though.
(I'm also guessing that, when two monitors are hooked
up, the CPU must calculate some sort of average of the
two monitors, which it then assigns as the
pixels-per-inch value for screenshots? - since a
normal screenshot shows real-estate from both
monitors. Anyway the discrepancy in numbers between
different models of Mac, happens even with only 1
monitor attached)
