I found the setting under Displays to automatically adjust brightness, but is there a way to set this different for Battery or Power Adapter? I would like to keep this option on for using the Battery, but would like the display at a constant level when using the Power Adapter.
View 3 RepliesI have an iMac, the screen has gone quite dark (as if in sleep mode) I have to sit in a darkened room to see it properly. Have I hit the wrong key or key combination of keys? How do I adjust the brightness?

The brightness goes up when you plug in your MBA, but then over time it just goes up and up. I honestly like my brightness pretty low (rarely more than half, typically at 3-5 notches), but it just keeps on going up and up. I almost never set it above half, but multiple times a day, I notice that it looks pretty high and it's at like 3/4 so I put it it down to about 1/3, but after a while, it's just up again.
Anyone else notice this? What is it, why does it do this? How can I fix it? I don't mind not having auto-brightness (even though I loved it), as long as my screen doesn't keep going up.
So I installed Vista 64 bit on my Macbook Pro (Santa Rosa), I installed most of the drivers I can find, but I cant get the screen brightness buttons to work (F1 and F2)

Does the new MBA still have the ambient light sensor that adjust the screen brightness to environment?(like the older MBA and the current MBP)

View 2 Replies View RelatedI've connected up my external monitor, which is a bigger Samsung 1600x900 and and I'm having some issues.. I'm trying to get the MacBook to recognize the Samsung when I plug it in and automatically adjust the settings, so I don't have to muck around with the settings every-time. Is there anyway of doing this? oh and disabling the MacBook's display so it doesn't detect it as a second monitor?

View 1 Replies View RelatedRecently, after about 5 minutes of use (not sitting idle), my MacBook's screen will go very dim. I hit the buttons on the keyboard to take the brightness all the way up, but it doesn't get much brighter and there's only one thing that I can do to make the screen go brighter: I go into System Preferences and click Display. The second I click that, the brightness returns without me doing anything in the Display section, so after Display comes up, I just close it out and the screen brightness is fine for a while. It seems to do this after the lid has been closed for a while and then starts dimming again after opening the lid and using it for about 5 minutes. Is there a way to fix the auto-dim mode without disabling it? MacBook (white) is running Leopard 10.5.8 with all the latest updates.

View 1 Replies View RelatedBasically what I want to do is sync my Apple Cinema Display's brightness with my MacBook ambient light brightness control. So when the brightness of my MacBook changes because of ambient lighting, my secondary monitor changes with it. Is this possible? Is there a software that does this?

View 2 Replies View RelatedThe reason I am asking is that I am using a Spyder colorimeter to calibrate my monitor and it is asking me which controls exist on the display:
-brightness
-contrast
-backlight
My thinking is that F1 and F2 control the backlight level and not the "brightness" level, if you get what I mean.
Just had apple replacing the display on my rev b air due lose hinges, I think this new display much brighter then the old display. It is just a psychological thing? or does the screen actually losses brightness over time/usgae?

View 1 Replies View RelatedI have setup the 23i cinema display with mac pro. I have connected the USB and firewire cable to mac pro.. and keyboard is attached to back of the display. For some reason I cannot seem to adjust the brightness of the display from the keyboard (though I can do it from the side of the monitor). Neither can I see the brightness slider bar in the display settings. Also while the display is the the power led in the front blinks 3 times, then there is a little pause, and blinks 3 times again. How to fix this brightness control issue with the display. I have reseted PRAM and NVRAM... still nothing has changed. Also note I do not have and options tab for some reason.... (I have tried to plug the display's usb into the back 3 usb of the Macpro... still nothing)
View 1 Replies View RelatedI have a 24" LED Cinema Display and can no longer control the brightness settings in OSX I believe when I applied the recent java/bluetooth updates the slider disappeared upon reboot. I did some searching and can't come up with a way to get it back. I'm using a 15" Unibody MBP, and the brightness slider for that screen is available and does work. I also tried setting the keyboard shortcuts on my main keyboard (external) to turn up/down the brightness but they won't function at all.
I have tried zapping the PRAM, repairing permissions, and disconnecting/reconnecting the display, as well as booting with no external display and nothing has made the slider reappear. I also logged-in as a different user and the slider is not there for the Cinema on that profile either. I really, really hope I don't have to reinstall OSX to get rid of this but I'm out of ideas. The worst of it is that I turned down the brightness to less than half (when it worked) becuase I had a headache and now it's stuck there!
I have just realised that the Brightness slider in Display Prefs on my Mac Pro is missing. Running SL 10.6.2 with an Apple 24inch ACD connected.

I have a 24inch LCD ACD display connected to my Mac Pro. This display all used to work OK, but now, read on. I had to send this 24inch LCD ACD display away to have the panel replaced. Since it has returned when I look in About This Mac/Displays it shows that I have an iMac connected as the display and now the brightness cannot be controlled. If the 24inch LED ACD is connected to my Macbook it all works as it should
does keeping a high brightness level all the time effect performance or display?

My wife has an iMac (I don't know any other way to identify it e.g. model number), and she has this 3rd party calibration software that I'm trying to use. I am not used to a Mac, and I cannot find the display settings for the monitor. There are no buttons on the monitor, and when I go to preferences, I can only find the brightness control. I've googled this and cannot find a clear, simple answer. I have used every version of Windows (currently on 8.1 on my PC) and it's easy for me on that platform. I suppose it's just that I don't really know how to navigate Mac OS.

My backlit keyboard has recently started to act up. It has recently started at random times to not let me manually adjust backlight at all, randomly turning it off and disabling the two buttons to adjust it. It is a Unibody MacBook 2.4
View 4 Replies View RelatedJust got a new MBP 15" AG this week and was wondering if you can adjust the sensitivity of the keyboard backlight. It seems to come on even in a fairly well lit room and I mainly only need it in a completely dark room. So I find myself hitting the backlight keys to turn it off and then whenever it wakes from sleep goes back to full bright. Didn't find anything in the keyboard preferences and found a program called Lab Tick which will take care of the level on wake.
