After every reboot, the brightness of my iMac's screen changes to 100% brightness, which is slightly annoying. Does anyone know why this happens? By the way, I'd say it does it since 10.5.8.
View 4 RepliesI have dual ACD's. How do I make it so that both screens have the same brightness? If I adjust the brightness in the display settings it adjusts the main screen, but then not the other one. How do I make them the same?
Just bought a brand new 15" MBP, and immediately after unboxing the screen brightness seems to just move/adjust without adjusting via brightness buttons.
View 5 Replies View RelatedAll of a sudden, every time I reboot, my screen's brightness is all the way up. So, I go to 'Preferences' and bring it down to only happen again the next time I reboot. Not a terrible problem, I hope, but not sure why the settings of this doesn't remain as I left it last. Perhaps I have picked up something OR I have a fault which could get worse?Anyone seen anything like this?
View 3 Replies View RelatedI have a Macbook Pro 13.3 ", only a few months old. When I use this, whether I use the word, web surfing etc then adjust the brightness of the screen itself from strong to weak and back, all the time. This happens both when connected power and do not. And no, it's not that it goes into power saving mode, this occurs during use.

I have the 21" iMac and need to brighten the screen. How do I do this?

View 2 Replies View RelatedAm I the only one having this bug? I have a 2009 24" iMac Radeon 4850 and after installing the 10.5.8 combo every time the machine boots the brightness is set to maximum.
I tried zapping the PRAM and that didn't help.
The other problem I noticed is that my startup network shares, even though checked to "hide" pop up finder windows at boot time. It never did this before (even without hide being checked).
I have a Rev A (Aug 2007) alum iMac (20") and ever since I installed 10.5.8, the screen has been set on full brightness on every startup. I'm currently running Snow Leopard and the problem persists. I erased and installed during the procedure so I don't think it can really be a corrupted system file or something.
View 5 Replies View RelatedThe 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.
In the last three days my iMac desktop has begun starting itself up. There is an audible beeping (three or four beeps) and the on/off indicator light blinks rapidly. When the screen comes up there is no desktop but a gray background with reboot instructions. When I type the reboot words "mac-reboot" the desktop comes back.
Under Logs in the system profiler I see the following message:
CGXDDisableUpdate:Updates disabled by connection 0x66-3 for over 1.000000 seconds
and
CGXBlindSurface returns-536870210
The computer is rather old, is running OS X 10.2.8 and has never done anything like this before.

I went to Best Buy yesterday and they just got the new imacs in and had on display side by side. The 21.5 display was not as bright and vibrant as the 27 display. The apple and best buy guys could not tell me why the difference. The settings were checked and found to be the same for both machines. I was going to get the 21.5 but now not so sure. I definitely like the brighter 27 better. Is this normal? Why is the 27 brighter? Has anyone else noticed the difference?
View 6 Replies View RelatedHas anyone noticed a very slight flicker on their new MBPs? I have a new 13" and, every so often, the screen brightness dims and then brightens very quickly (happens in less than a second).The option for auto-adjusting the screen brightness is off so it's not that particular function.It's most noticeable on all-white backgrounds both on AC and battery power. Hard drive access doesn't seem to coincide with the dimming.
View 17 Replies View Relatedlately, my mba has been behaving a little weirdly. its screen would suddenly become a little dimmer when the brightness in the room has not changed a bit. after a long while(15 min?), it'll turn brighter again by itself, and again without any change in the lighting of the room. the change is not big but obviously. any idea? can it be some software? or setting? or a defective light sensor?
View 2 Replies View RelatedI have a 2007 aluminium imac running Snow Leopard. It needed to have a disk drive replacement recently under applecare. Since I got it back I have noticed a marked dimness in screen brightness starting about halfway down the screen, most noticeable against a window with a white background. It is pristine white at the top of the window but from about halfway begins to get dimmer. Its a bit like being in sunlight and the coming into shadow, or finding mist creeping into the picture.
I have tried recalibrating it but it makes no difference. It might have been there before the repair but if it was I didn't notice it or else I grew used to it but now I find it quite distracting and it does make text a little harder to read as I'm getting on in years and my sight needs all the light it can get. Is it normal or is it a sign of problems beginning to manifest themselves with the display? I wouldn't like to ignore it & find myself out of applecare cover when it does.
So I have noticed a few times already, that the screen on my white macbook flickers to change the brightness level. It can do this while the computer is plugged in and charging, or if it's off the charger. It is definitely noticeable as it causes me to just watch what the screen is doing.

View 1 Replies View RelatedIn the Windows version of Skype there is an option to disable Skype's auto-adjusting of the microphone volume.
But in the Mac OS X version it seems it takes over and will adjust your microphone volume, without even asking, and there is no option to turn this off.
...Or is there? My audio volume keeps lowering itself while in a game, and the only way to put it back is to go into System Preferences and raise it up. However I watch the volume slider go back down by itself because of Skype.
I just got a new 15" MBP and it keeps changing the screen brightness by a couple notches either way on it's own. Anyone have/heard of this problem?

View 24 Replies View RelatedI usually have my screen brightness set to a few ticks above the lowest, but when my screen shuts off (after 3 mins or whatever I have it set to in the control panel) and gets turned on again, the brightness is set to max. If I then drop the brightness by one tick, it drops to where it was set before. It doesn't do this when I close the lid but it does go to full brightness when I restart the computer and as I enter the windows desktop it goes back to what it was set at.
View 3 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.

I tried Shades but it messes with the colour making it look a little washed out and not good.
Are there any others I could try ?
I dropped my laptop on a tile floor and the bottom hit it flat. my computer works fine besides the fact that my computer screen's brightness is as if my brightness level was all the way down.

View 24 Replies View RelatedPurchased my iMac 27" back in October 2011. It was fine up until around February this year until my screen brightness started flickering automatically. I have the ambient/auto brightness setting switched off and after many discussions with apple care on the phone I have been advised to bring my iMac back in to the store.
1) is this a common problem a lot of people have experienced with iMacs?
2) Do you think it will be repaired or replaced?
3) Does this happen with the macbook airs as I was planning to purchase one for university in September, however if this problem occurs with their laptop range then I will opt for windows.

I wanted to check out Windows 8 so i decided to install it using Bootcamp on my Macbook Pro. I installed it successfuly, along with the Windows Bootcamp drivers, but my Display is VERY dim, the brightness is all the way up to the Mac. I rebooted the Macbook Pro and ran OSX and the brightness is fine, but on windows is very very dim and idk how to fix it.

I was wondering if/where I could get a better screen for my 12.1" Powerbook... Better viewing angle, brighter, possibly glossy. OR is there a way to bump up the screen brightness by just putting more juice in it? I know it would hurt battery life, but while it's plugged in it wouldn't hurt.
View 5 Replies View RelatedWhen I push the brightness key on the keyboard, the appropriate image comes up on screen and goes to full brightness, but the actual brightness of the screen doesn't change and the lack of change is reflected correctly on the brightness slider in System Preferences.
