My iMac's screen brightness started to fluctuate a few days ago, dimming / getting brighter. There's no ambient light sensor (as far as I can tell) on the iMac.

iMac, Mac OS X (10.7.2)
My IMac screen keeps changing brightness as I use it, currently the LHS of the screen is not as bright as the right. Â
Does this sound like an adjustment or a fault? The sytem is about 6 months old from new.

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)

Purchased 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.Â
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.Â

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

I have a new MBA, 13" which I'm loving so far. I like the screen bright - like almost all the way up all the time. Other than shortening my battery life, will this setting cause any damage to the screen?

View 24 Replies View RelatedI've had bright spots appear behind my LCD screen for the second time this last month.
They look like the LEDS from the backlight are pushed up too close to the LCD and sort of washout the LCD in that area. The have occurred on the left side and the right sides along the lower edges of the screen.
I'm fed up with all the repairs this laptop has needed and feeling that I paid 2000 dollars for a quality product I went to the apple store today and asked for a replacement unit.
I was told that the recurring bright spots (on top of 3 other minor repairs and 1 major repair) did not warrant a replacement unit. The manager even said that they shouldn't have fixed this problem last time because it is cosmetic and not covered by the warranty. The genius also repeated the phase "This doesn't happen by itself" (I nice way to say I did this and that they shouldn't cover it. )
The manager decided to make me feel special and say something along the lines "We'll fix it again this time because we did last time".
My warranty is running out in 6 months and I need to know what's causing this. I always transport my laptop in an incase sleeve with a shoulder strap. There have never been any external marks on my casing when these dots appear. If I put too much pressure on the screen wouldn't the middle bend in more and I would get problems there? There weren't even marks on the screen from the keyboard keys yet I put enough pressure on it to cause this without even knowing it?
The best part is I asked the man who gave me my repaired laptop back how to prevent what the manager called 'LCD bruising'. When I mentioned bright spots he said 'Oh that's a defect we cover under warranty'.
Im going to contact apple's customer relations on monday regarding the repeated repair trips. I have no confidence this laptop can go a long period of time without needing repairs.
It's not the keyboard sticking.

Why does my screen look dull? It's not dull like when you stop charging it, nor is it as bright as when it is charging, it's about in between. I have it plugged in and the battery constantly reads 95% never 100%. The little green dot is on the charger input and the battery symbol shows that it is being charged so I know it's charging. What reason would be why my screen is not as bright as before?

I bought a MBP last weekend, and noticed in the last few days a few bright "spots" on the screen in the top left hand area of the screen. It's like the complete opposite of a dead pixel - it's just bright and whitish. It's almost like a speck of glitter on the screen! It's only visable from certain angles, but is one of those annoying little things!

View 15 Replies View RelatedHave a late 09 i7 27" iMac with XP SP3 installed on Bootcamp partition. Even after turning down brightness in BootCamp control panel all the way down, I still feel like I'm staring at the sun. Screen is still way too bright. No such issue in OS X. Is there any Windows app (similar to Shades) that allows further brightness reduction? With brightness as is, Bootcamp is pretty much unusable to me.

View 4 Replies View RelatedI just got a new MBP 15 i5 2010 with a high-res anti-glare screen.
Manufacturer: 00000610
Model: 00009CBB
Serial Number: 00000000
Manufacture Date: 00000000
Unfortunately the display doesn't show very light colors. (compared to my old MBP15 2007) If you look at the attached image [URL]
- at section 5 I can only see the Grey boxes from 235 to 247, and I CAN'T see any Grey box from 249 to 253.
- at section 3 I can't see the Grey box at 5 all the other from 10 to 50 are fine.
Changing the brightness, playing around with different color profiles and resetting the system didn't solve this problem. I called Apple support and after some resets I was asked to compare my screen with the same make/year. Does anybody has the same 2010 MBP15 high-res anti-glare display and experiencing the same issue? Does your display work fine and is showing all the different Grey boxes?Other MBP owners: Can you see all Grey boxes on your MBP screen? My brothers 2009 MBP15 is showing all light Grey boxes from 235 to 251. 253 can't be seen
Has anybody seen this on their Macbook Air? A very bright, fading line of 6-8 mm at the top of the screen? I just returned my MBA because of this a couple of day ago. Then today I go to the local apple dealer (in Denmark) and I see the exact same bright line on the MBA screen in the shop. I also checked a unibody Macbook, a white Macbook, and an 24" iMac. None of these screens had the problem - it was only the Air. So now I wonder: is this a feature of the MBA, or was I right in returning it because of this.
View 1 Replies View RelatedI'm looking for a external monitor that is compairable in brightness as my iMac's screen. The brand needs to be Samsung, and the look of the Samsung moniter I would prefer to look like the examples below. Why? Because I want it to match my TV. I'm also looking for a small monitor because the space I have is pretty small and I dont want to have to move my iMac and look at it at a angle. I currently have a Samsung SyncMaster 906BW with a 1440 x 900 60hz resolution and its VERY dull compared to my iMac and its at 100% brightness and 85% contrast. Here are some of the screens I'm looking at so far, would they be close to as bright as my iMac's screen?
View 1 Replies View RelatedI just bought a 12" powerbook from craigslist. The guy I bought it from powered it up outside in the sunlight so I didn't notice until I drove an hour home and booted it up. The bottom of the screen towards the very center is extremely bright compared to the rest of the screen. I discovered that if I push on the bezel right below the LCD, the screen normalizes. However, I can't see anything that looks bent, dented, or cracked anywhere on the screen, bezel, or back of the LCD.
View 7 Replies View RelatedI just noticed that on a black background, my 17" i7 MacBook Pro has two areas in the lower middle area of the screen, where the backlight is too bright compared to the rest of the screen. It is very noticeable on a black background and grey.. Is anyone else having this problem?
Other things I noticed:
- there was dust on the plastic cover that you take off the case when you use it for the first time
- the aluminium enclosure was slightly dirty, could be rubbed off though..
- there are two minor 'impurities' in the aluminium (?!).. two tiny grey spots/blemishes basically
- there were a few minor scratches on the aluminium casing.
- the apple logo at the back glows in a much warmer (yellow-ish) colour than the previous generation mbp (?!)
- the screen seems not as bright as the previous generation
- the keyboard backlight seems not as bright as the previous generation
Has 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 13 Replies View RelatedI got myself a Macbook a couple of days ago. It's also the first Mac I've ever used, so I'm not fully acquainted with all the OS characteristics. In particular I'm puzzled as far as the battery monitor is concerned: the time it shows keeps on fluctuating: as I'm speaking it first shows 3:02, then 3:11, then 2:52, then again 3:00, then 2:43 and then again 3:02 (all these values in less than, say, 5 minutes).
View 3 Replies View RelatedThe battery time on my Macbook Pro 15" goes from one time to another in a matter of minutes. I fully charged the battery after it had been drained. This is what I mean by fluctuating:
11:23am-11:28am (5m)
7h51m, 5h54m, 6h57m, 6h16m, 5h29m, 6h38m, 5h53m, 6h29m, 6h9m, 6h13m
11:29-11:34 (5m)
6h39m, 6h36m, 6h4m, 6h8m, 6h49m, 5h52m, 6h30m, 6h0m, 5h43m, 6h30m
Apple states that it should get 8-9 hours on a full charge and mine gets 6h15m. It's only 10mos old.
