Is this true - I've read articles with varying ideal measures of how far the
eye should be from the screen - 5 times the diagonal, 8 times the height (which
is almost the same thing), >6 times the diagonal, etc.  Does anyone have a
definitive answer?

What are the effects of closer viewing - eye strain, visible scan lines, what?
I'm tempted to get a 30+ inch monitor when I upgrade, but what if the couch is
only 10 feet from the screen - would I be sorry I got a "too big" screen?
