If there are,
"lots of novice computer users who never realize that there even ARE brightness controls on their monitors", then the problem is with those users, not their LCDs!
I asked how you would fix that problem, and you answered "RTBM".
Are you suggesting that there is a manual about computer users that I should read - which would fix the problem?
Or, if you're suggesting that there's some way to force computer users to read the manuals - which would fix the problem?
It's easy to say that "those people" are the problem,
if you don't have to provide a solution. Or if "just ignore reality" is a rational solution.
I'm just asking how
you would fix the problem that
you stated.
