Do modern screens still actaully suffer from burn-in?

I've certainly been fooled once or twice into thinking that a machine is
dead by choosing the wrong keyboard to hit Ctrl on.  I've also
occasionally had to repeatedly nudge a machine to see how it's getting
on when observing it's progress from afar, which is a bit of a bore.

How about if we set the timeout to something that should be considerably
longer than the largest interval between user input during an install?

12 hours doesn't seem like a bad number, but if we went for 24 hours
then the screen would still be cheerfully blinking with a prompt the
next morning if you launched an install just before going home from
work.

Do we realistically expect to do significant damage to the screen (or
the environment) by very occasionally leaving a screen on for 12/24 hours?

Cheers, Phil.
