    I just got my new MBP 15.4" and so far it's perfect. I have no yellow tint, bleeding or anything (LG screen).

    The display is amazingly bright.

    I was wondering if having it set on "max brightness" would somehow reduce the brightness level over time. Would it be "healthier" for the display if I set the brightness level to say 80% or so?

    Sorry if it's a stupid question : (

    Thats a good question!
    I just got mine and was thinking about the same issue.
    Do you have it all time at 100%? Sometimes I even start thinking that it is too bright :D

    Well, yes.

    I like it at 100%. But if using it at 100% will make the screen less bright over time, I won't be maxing out for long.

    I don't know if using it at 100% brightness will significantly reduce the brightness of the display over time.

    Regardless, you should use it at whatever brightness level you find most comfortable. It makes no sense to try to preserve the life of your machine if you're not going to enjoy using because it's too dim or dark.

    Will there be a significant difference? Is this proven?

    The entire point of using a new technology known as LED backlighting is 2 fold.

    1- It uses less energy and prolongs the length of time you can use battery power to operate.

    2 - CFL backlighting loses brilliance, or brightness over time as the mercury atoms deplete. LEDs suffer no such effects, thus DO NOT diminish over time

    So basically have at it and go as bright as you want there cupcake....

    Well, lowering the brightness does significantly affect battery life. And since the screen is unbelievably bright, I usually keep it at about 75% which gives me over 4 hours of battery time.

    LED's remain at their brightest until they die, which will be years and years.

    any specific numbers? how many years?

    "The usually quoted LED lifespan is 100000 hours of on-time before falling to 80% of the original brightness"

    So about 11 years.
