    I bought my macbook in December and my sister just bought a macbook today. They are both the same model (core 2 duo etc). Is this normal for the screen to get dimmer like this? Or has the macbook screen been upgraded in the last model update?

    As far as I know, that's a limitation of the technology. CCFL backlighting naturally grows dimmer over time.

    Which is why Apple's stated goal is to switch over to LED tech for all flat panels as technology allows and costs come down.

    It shouldn't make that much of a difference in 6 months though.

    They are both using the default "Color LCD" color display profile.

    If I use, lets say, 1/2 or 3/4 brightness, will the "max" brightness last longer in the long run?

    to me it looks like a different colour profile, the colours are different try changing them both to another one like the adobe 1998 or whatever it is

    Any chance that Apple updated the screen?

    Also, do the LED screens fade over time, or just the older LCD screens?

    i think everything fades over time :D

    maybe this brightness difference can be that the displays came from different manufacturer? you should check if the displays are LG or Samsung.

    go to display preferences and pick the default "Color LCD" profile then click open profile. then look for section 13 "apple display make and model info" then check if those two monitors are the same model.

    IMO, i think either the colour profiles are diff or you have two displays from diff manufactories. it should not be THAT much difference if its only 6 month in between. But again, if you use urs a lot like almost 24/7 then...yeah...yours is due to the usage.

    cheers,

    My one-week-old MacBook has another screen than the half year old MacBook of my friend. Mine is a bit more grainy, but a lot brighter.

    Or better yet, separately calibrate them both yourself, using the utility and your eyes, and then look at them together again? Granted that, in the photo, we all see a difference, it's not that reasonable to expect a stock profile that ships with the computer to produce the same results on both computers... that's the entire point of calibration.

    The LED backlights will not fade over time.

    But--remember that on a long term basis, even a little bit of precaution can stretch your screen a long way. (If you're concerned about six months, my ibook is on six years:)). I imagine keeping the brightness down would reduce the heat and potentially extend the lifespan? More likely, setting the screen to turn off sooner, using an external monitor at your most commonly used workstation, and simply accepting it are your best options. If you need the maximum brightness, please, please see an eye care professional. :D

    Besides a slight, very slight chance there would be different opacities, the manufacturer of the backlight is more important for brightness. As far as I know, the manufacturer of the LCD panel proper would be irrelevant.

    Ding! Each piece of hardware is never the same (variations, different brand, etc); maybe the older one might be dimming, but the color is definitely different between the two. The only way to really see is to calibrate them both to the same eyes and compare it. The built-in default profile is set the same on each system, but will have a different outcome on each one - just like tuning a vehicle - you can't just pop someone else's tune into the system and expect it to operate or perform the same.
