New acd's brighter?

at work we've had 2 20" acd's at each workstation for about 2-3 years now. we just got new 30" acd's, so each workstation will have a big one and a small one. i've set up one workstation and there is a noted difference in the monitors. the 20" that we've had for a while is significantly dimmer than the 30. is this because the specs have changed and the displays these days are brighter? or is the dimness a reflection of the wear 2-3 years of constant use will have on LCD screens?
i guess basically what i'm asking is are my older ones fading on me or are the new ones just made to be brighter?
i would hope that the brightness life of LCDs is longer than that...especially since i'm considering purchasing an LCD tv for home use...if it starts dimming in the space of 2 to 3 years, i may have to wait for OLEDs to come out.
anyway, any thoughts would be appreciated.
thanks

There was a change a year or so ago that increased the brightness.

FYI: New ACD Specifications

I spoke with Apple today to determine what the deal was with the recently upgraded brightness and contrast specs for the 20" and 23" Cinema Displays. They indicated that the change was actually (quietly?) made back in April 2006, and that any monitor recently sold directly by Apple should be one of the newer models. All bets are off as to age of stock for third-party distributors. Note that it would appear the Apple Part # has not changed, and that there is no date code or serial number string that can identify it as the 'newer' version without entering the number into their computer system.
Incidentally, I noticed that many of the 'ghosting' issues (or 'image persistence', as Apple chooses to term it) have cropped up in the last few months. It makes one wonder whether or not the new (upgraded) and brighter backlight has indirectly caused these issues. Since people may have been receiving these new displays for a few months now, it's at least conceivable that there is a connection. It now leads me to wonder whether the recent price drop is market-driven, or is related to this latest batch of stock which could possibly be sub-standard. I sincerely hope that is not the case, since I just bought a 23" ACD.
Be careful out there...

That was interesting.
Do you detect any backlight leakage on yours in a
dark room with the screen entirely black? That might
be an indication of an improved display you got.
To make my short story longer, here's my deal:
Bought a refurb 23" from Apple about 3 weeks ago for $1099 (ouch!), had 9 dead pixels on the left side of the screen ONLY, no ghosting issues, good color, slight backlight glow along bottom, though very good blacks (not purplish). They agreed to refund me.
Second one is now sitting on my desk via CompUSA (post-sale), May 2006 build date (per Chipmunk, thanks for that guys), only one dead pixel on the extreme right side of the screen, very good color and uniformity, some minor backlight leakage (with blacks appearing slightly purple, though not calibrated yet), but has some erratic ghosting issues. The image persistence is worst when you leave a white background with black graphics up for awhile, but it does go away, and is difficult to see with anything but a uniform desktop color (grey, especially). I'm becoming afraid that the 'image persistence' issue is a necessary evil of the upgraded backlight, though I also wonder whether or not breaking the thing in for awhile will make decrease the ghosting. The date of Apple's article on 'Image Persistence' might also lend some credence to this...
Gorgeous monitor, though, simply drop-dead beautiful.

17" ACD gone bright pink

This issue could be with the Apple ADC to DVI convertor box or cable, but I can't confirm if it is that or my monitor. I am using a 17" clear ACD with a mac mini, and I started to get intermittant bright pink screens, which has progressed into pink all the time, and a horizontally squashed screen that shows the desktop twice (one on top of the other, both squashed).
I am pretty sure that the cable coming out of the convertor box is the culprit, since I was able to get it working normally by jiggling the cable, and it started acting up when I was plugging and unplugging some USB devices. Now it won't work properly at all, and I do not have an old computer to plug the monitor in directly to check with. I did plug the monitor and convertor into a G5 PowerMac, and had the same result. When I plugged in a newer 20" Apple aluminum display into the Mini, it worked fine.
The trouble is that all of the cables on the monitor and convertors are built in and not easily replaced.
Any suggestions?

Yep, I had to buy a new convertor box to fix the issue.
Please, Apple, make your products with removable cables!

ACD 23" Brightness controls inoperable

Like SO many other people I was having trouble with my ACD 23" monitor not turning on at start up. By swapping out components with an identical monitor, I determined that the problem is most likely the power brick.
I am currently using an identical power brick borrowed from a friend and the monitor is working again, but now the monitor runs at FULL BRIGHTNESS all the time. I have no ability to adjust the Brightness throught the control panel, monitor buttons or F14/F15 function keys.
I have tried rebooting to correct it, but no success. Is it possible that a preference file needs to be thrown away and rebuilt, or could it be something else??

I am having the exact/identical problem. I purchased my 23" Cinema Display three days ago. Everything was fine then all of a sudden, without touching the keyboard or monitor the brightness icon came up and increased to full brightness. I rebooted... nothing. None of the side control buttons work and my monitor light is not on, although the display is on (& at full brightness). I tried going thru System Preferences -> Monitors -> brightness, but it overrides the brightness that I slide to and goes to full brightness.

Waiting it out for new ACD revisions?

I am on the edge of splurging for either a new 23 or 30 inch ACD, but I would kill myself if I bought one right before a big revisions. I have read the rumors and all, but I still have absolutely no idea what to do. To go for it, or to wait. Any suggestions??
Maybe a 24 inch HD LED introduction will come after a bit, and if that were the case, I would hate myself for buying a 23 ACD now.

"Maybe a 24 inch HD LED introduction will come after a bit, and if that were the case, I would hate myself for buying a 23 ACD now..."
It will be two weeks after you buy a current model....;)
Seriously, new displays can't be far off. It's been several years since the current line up was introduced and the displays are now the "oldest" products in the Apple lineup...

New 27" iMac Brightness Control Missing

I have a brand new 27" iMac. Currently the only things plugged into it are the Apple-branded wireless keyboard and mouse that were included with the iMac and ethernet. I waited for the 10.9.2 update to see if that would resolve the issue, but it has not. I have also performed multiple PRAM and NVRAM resets.
The F1 and F2 keys on the Apple-branded keyboard do not decrease or increase the brightness of the internal display. In System preferences -> Display, there is no brightness slider at all. It is behaving as if I plugged in a generic 3rd party display.
I am about to copy over the
AppleBackligt.kext
AppleBacklightExpert.kext
AppleUSBDisplays.kext
from an identical 27" iMac (that doesn't have this issue) to see if that will resolve the issue.
Unfortunately, a complete reinstall of Mavericks is not an option at this time.
Thank you in advance for all your help and suggestions.
Edit: fixed title typo

It is currently unavaible for reinstall, due to the time (albeit short) required. If I can't fix this another way, that's the route I'd like to take. I'm just hoping I can find a more direct solution, and to find out if this issue is just this machine or broader.
The steps I plan on taking right now are,
Verify the display is properly set up by Apple (maybe the internal USB isn't plugged in right?)
Replace .kext files listed above from an identical iMac with working brightness.
Dump any preferences related to the display I can find.
Reset NV/PRAM again.
Reinstall the OS.
Replace.

Is new 15 power bright then old 15

Is the new 15 inch display bright then old ones it saids the the new 17 inch is 46% bright how much bright is the 15

looking at the news lately it appears that nothing coming from Intel is just "around the corner"....
I prefer to buy from well-revised Apple products, as the first ones have more possibility of being buggy. Take the 15" PB's, for instance, w/ the white spot and lower mem slot issues... few rev's in, all kinds of problems dissapear!
I assure you, "mactel" purchasers are going to buy into one **** of an adventure, I'd get while the gettin's good, not that there's any real rush....

Calibrating a New ACD Aluminum Widescreen

I just purchased a monitor that is apparently from the last production run of the wide screen 20 inch Aluminum Apple Cinema Displays. They were discontinued in February and are the last of the low glare ACDs.
My question is, what is the best hardware calibrator for this display? I know that this display has been around for a while and has gone through a few iterations, so was wondering what seems to work best in the most recent ones, say 2007-2009.

New Macbook Air: bright flash during startup

My week-old Macbook Air 13/4/256/1.3/i5 gives this bright bluish blink every time it is started up, a second before the desktop comes up: http://youtu.be/mPDFQTPRuY0
Is this normal or should I be concerned?

My 2011 MacBook Air does the same thing -- or at least very similar and at the same time, just before the desktop displays. I hadn't noticed it until I read your post, partially because I so rarely restart. I usually just close the lid and let it sleep; sometimes several weeks between restarts.

Brand New ACD 30" has problem starting

I've had it for 1 month now without issue. Until yesterday, it had started right up when I would boot my G5 in the morning.
Now, when booting in the morning, the display's power light starts to flash sporadically and the monitor remains lifeless after hitting the power on the G5. I have to hit the power/sleep switch on the side of the display several times before it lights up. It appears to function normally after it turns on. And this only happens in the morning when the display has been shut down for several hours. If it's warm and has been running and I reboot there is no problem with it starting up right away. I'm using an ATI Radeon 9600 Pro AGP.
Any idea what's going on here?

Sent it back to Apple for repair on Monday. Got it back today (two days! wow!). They replaced the panel. Power issue seems to be gone. But exactly what I was afraid of has happened. Dancing green pixels everywhere when I'm viewing something that is dark or has large expanses of black (ie. movies, slideshows...etc).
It amazes me that Apple continues to sell a product that is so problematic for so many people. I suppose I'll need to send it back yet again and hope for the best.

Is the new ACD 30 reliable?

Guys, I've just gone through a number of DELL 30" (3007WFP) and was very unhappy. The three monitors I had emit a buzz from the backlight which can drive you crazy. That's why I'm considering an Apple now. Can you share from you experience if the monitor is quiet and your general satisfaction factor?

2 ACD 30" running on NVidia FX 4500--why is one brighter than the other?

Last November 2006 I bought a new MacPro, 2/3Ghz Xeon, 4/500GB SATA drives, 4/1GB 667 MHz DDR2 DIMMs, and NVidia Quadro FX 4500 video card to run a 30" ACD. July 2007 (last week) I added a second 30" ACD which is noticeably brighter than the first ACD. This holds true whether running OS X 10.4.10 or Windows XP Pro w/ BootCamp 1.1.2.
After 2 hrs on phone, AppleCare advises an appointment with AppleStore "Geniuses" since it's 8 mos old and still under warranty. Today, local Geniuses respond: "it's just newer technology, nothing wrong with either one"; "you didn't buy it from us (MacConnection)"; "dim down the bright one to make it match"; store manager offers to send older one back for unspecified repair but adds "it probably won't make any difference, and since you didn't return it within 14 days of purchase (last November) we can't exchange it for a new one. Besides, you didn't know there was a problem until you bought the new one,right?" The geniuses are uninterested in making a side-by-side comparison with a newer ACD and stand silent waiting for me to give up.
Has anyone else experienced a similar problem with two ACD 30s running on a MacPro? Or this trademark indifference with respect to service?

Hi and welcome to discussions.
I think there is some natural minor variation between LCDs bought at the same time anyway. They also do tend to become slightly dimmer with age. However, Apple did update the specs on the 30" ACD during 2006, including the brightness. According to the following article it went from 270 to 400 cd/m2, a significant jump:
http://arstechnica.com/journals/apple.ars/2006/3/28/3369
When you bought in November 2006 I guess it's possible you got some older stock, especially if you bought from a third party retailer. I suspect there's nothing actually wrong with the displays themselves and hence they can't be 'fixed', other than to make some manual adjustments to the brightness etc.

ACD with PC

hello,
i want to buy a new ACD 30" for my new PC workstation.
my graphics card is nVidia 8800GTS 640MB. maybe in the future i'll add another one but not at the moment.
now i would like to connect the 30" to my PC.
i also want to run another monitor with it as a dual monitor(LG CRT 19").
is it possible? and will it run at full res with this graphics card?
and another thing,
i've heard some trobeling things regarding the 30" esspesially with a PC,
first about the speed, does it run HD and simpler video strems fast enough?
of cours i'm not talking about games.
and second, will i be able to control the monitor sepc from my PC, like brightness and such?
i'm really looking for help, cause at the moment i'll figure everything out i'm getting a monitor.
tnx alot,
S.

Tristam,
I have an Apple 20-inch LCD monitor connected to my Athlon Windows machine. It works great. My video card is an ATI Radeon 9600 (I paid $80 USD for it).
I have also connected my 23-inch Apple LCD to the same WIndows box and it also works.
I think Apple makes beautiful and functional displays.
