Hi Russel
While LCD's are CAPABLE of reaching extremely high brightness levels
(easily over 300 cd/m2), it's generally not considered a good idea to
turn them up much past 150 because the backlight dims as it ages and
thus it is hard to hit the higher luminance with an older monitor. If
you always kept your monitor at max luminance in a well lit room, in
less than a year you wouldn't be able to use it in that environment.
So your students probably have the monitors turned up too high.
This begs the question of how are your monitors calibrated and
profiled? Do you have a policy regarding the manual controls on the
monitors, or are students allowed to set them as they please? If
everyone is adjusting the monitors to their own tastes, you will
inevitably get inconsistent and undesirable results upon output. All
the monitors need to be consistent, and that usually means fairly low
luminance levels (120-150) in a dim room.
Here's a link to a good explanation from Robert Bullivant about
recommended luminance levels: http://lists.apple.com/archives/colorsync-users/2006/Nov/msg00116.html
Personally I think 100cd/m is a bit low, and I don't think Eizo
recommends this anymore (couldn't find anything on their website), but
all the concepts are right on.
