Do Cinema Displays vary in lightness?

I’m testing a Cinema HD 23" Display here, which I would like to purchase. Hooked it up to my old G4 with Radeon 9000 graphics card. Works fine. What I noticed is that it’s incredibly light, much lighter than other Cinema HD Displays I worked with elsewhere. With the default Cinema HD profile it looked very light, even with lightness dimmed all the way down. After calibrating it got better, but I still have the lightness dimmed down more than half. Is that a common thing? Is it the graphics card, the OS (10.3.9)? Am I paranoid?

Hm.
Yesterday I looked at a 23" at a local Apple reseller. Brightness was turned all the way up and it ran the default Cinema HD profile (OS 10.5). Looked much darker.
Could the default ColorSync profiles vary from OS 10.3 to OS 10.5?

If plugged into the power supply, should the Cinema Display A1081 standby light come on without being plugged into a mac

I was given an old Cinema Display A1081 a few years ago. I am trying to test it and want to know if plugged into the power supply, should the standby light come on without being plugged into a mac? I don't want to buy a DVI to mini display adapter if it isn't working. One thing I did do was plug Monitor power in and then the USB plulg into my PC laptop and my iPhone charger USB plug into the back of the monitor. I am able to charge my iPhone this way so I know that the power supply is working. But I can't tell if the monitor itself is workign as no ligths are on. (PS: I am purchasing my first Mac so I am a complete newb but very proficient with PCs) Thanks so much for your help.

Just a final question about Sleep mode - does this have any negative effects on the life or performance of the laptop? I'm so used to Shutting down the laptop each day that I worry about Sleep mode having some sort of drain on the components or something.
There are only two practical differences between Sleep and Shut Down:
1. Sleep will wake instantly, so you don't have to wait for startup.
2. Sleep will drain a new, fully charged battery after several days without being woken or plugged in. If you shut down, the battery charge lasts much longer. Obviously, if you only sleep it overnight, you'll still have plenty of battery left in the morning.
Don't sleep it more frequently than necessary, though. Frequently turning the backlight and hard drive off and on can shorten their life. Just do what's reasonable. I usually leave mine awake until I have to transport it in a bag, along with sleeping it overnight. On battery, I'll sleep it more often to preserve battery.

Cinema Display 23" Power Light Out

The monitor works but the power light no longer stays on.
Is this bad?
When I first boot up the light comes on, but after the grey screen the light goes out.
The monitor seems to be fine but this is a strange new ocurrance.
Going to apple store tomorrow to ask a few questions.
Anyone else have this happen?

"That's a little like GO on red and STOP on green, isn't it?"
I think the "logic" goes something like this:
When the display is on, it's obvious that it is on right? You can see the image on the screen right? So you do not need a glowing LED to tell you that it is on. But when it is sleeping, the screen is black. There is no way to tell if the screen is asleep or off because in both instances, it's black. So the LED lights when the display is sleeping so you will know that it is still "on". When you actually turn the display off, the screen is black and the LED is off.
Please do not ask me who is responsible for this "very logical" approach. It just goes to show that even logic can be subjective.

Cinema display adapter for Mac Book Pro

I have an old 23" Cinema display. Which adapter do I need to run it from my MacBook Pro purchased May 2008? (I was disappointed when I tried to hook it up with the extant cable)

There are a number of Cinema displays variants and not all have the same video ports. Please look at the back of your display and post the Model code. It should be a 4-digit number preceded by either an "A" or an "M"

Connecting MBP & Cinema Display

I just purchased a MBP 2.4 C2D 15" and have a Cinema Display (20") newer aluminum model. What I noticed is that when I use the Cin Display with my MBP and CLOSE the MBP lid (screen) DOWN and use just the Cinema Display, the sleep light on the MBP comes on in a steady light, not pulsing like it does in sleep. So far it goes to sleep and wakes up out of sleep properly - sleep as defined as sleep light pulsating and HD & functions stop.
My powerbook does not do have the sleep come on when I use the cinema display with it. No light comes on as the computer is in use. And I'm concerned there's something wrong with the MBP. Any others out there who have the same set-up PLEASE let me know if the light comes on for you when set up w/ a Cin Display.
I've been on the phone w/ applecare for over an hour and he doesn't know.. now I'm on hold for someone else.. It's got to be a simpler answer than that. Either it's not supposed to do that or it is. Hopefully someone who knows will take the time to respond. Thanks much!
Regards.
This is a rewording of another post I put up, perhaps this is more specific. Thanks.

Well, I think I finally have an answer... I spent 2 hours on the phone w/ applecare (for such a simple question, but no one seemed to have the answer) and it was stated to me that with the MBP, when in clamshell mode, the sleep light does come on (in steady pulse) when using an external monitor. So that's what I'm going with.. So if you're wondering about the same thing as I, this I what I was told from apple (applecare) and she polled several other people who actually use the MBP in this way.

30-inch cinema display: a thousand points of light

I've been using my refurbished 30-inch cinema display for a month now with a new Nvidia Geforce 6800 Ultra DDL card. Moments ago I found my display was "enhanced" by thousands of teeny tiny points of yellowish greenish light. I changed the desktop image and it doesn't matter what it is. They're still there, though they change location with each image. Any clues?

No, the cable is slack. I restarted my computer and the monitor came back just fine, so now it's a nonissue. It's always something, though . . .

What do the power light blinking codes mean on cinema display?

I have a cinema display on my G4, and about a year ago or so I had to replace a backlight due to a failure. Tonight I see that the power light is blinking again in a repeatable sequence, and I am wondering where I learn what the sequence is telling me about the nature of the problem?
Power output of the display is reduced again, and I am hoping I do not need yet another backlight repair.

The meaning of the blink codes is not stated in the manual, but in this knowledge base article:

MacPro & 30" Cinema Display - Display stays Black at Boot/Will not light up

I just rec'd a MacPro 3.0GHz/8GB/4-500GB and a 30" Cinema Display.
After connecting all of the cables, when I start the Mac, the display remains black. I have also tried another video card and a 23" Cinema Display as well.
The indicator light on the display blink 3 times, and then a short pause. I have reset motherboard, pulled all ram and re-inserted, and swapped video cards and locations.
I have a wireless keyboard and mouse, so resetting PRAM is out because I can't even get to the Register Bluetooth Device screen!
Any ideas on getting things started?
MacPro 3.0GHz/8GB/4-500GB Mac OS X (10.4.7) MacBookPro 2.0GHz/2GB/160GB

The primary card is the std 7300. The other card is an NVIDIA Quadro FX 4500 (PCI Express) from a recently purchased Quad 2.5 G5, that Apple said is compatible.
I have tried the cards in all onfigurations and in all possible slot configs as well, utilizing both DVI ports for each trial.
I have pulled/re-inserted the RAM, and all cable and drive connections.
Still get two short and one slightly longer blinking indicator light on the display, whether the Mac is powered on or not.
Both displays work with other computers attached.

23 " Cinema Display - Black Screen but power light on

Hi all.
Last night my 23 " Cinema Display (aluminium) went black, after I repluged the video lead back in the graphics card. The power light is on the display and if you press the button at the side the powerlight glows brighter before going off and if already off it glows brighter before coming on (but still no display). Attached the unit to a g4 powerbook and still no video and no options for the monitor in system preffs. Although you can see the usb devices.
Any advice
Cheers
Steve

Hi all.
Quick update.
I took the power brick to work and tried it on one of their displays and everything is ok so it's not a brick problem.

Mac Mini 2012 and I want to use a new 27" Lighting Display and my old 27" Cinema Display as a second Monitor

Evening all,
I have a Mac Mini that I have been using a 27" Cinema Display on for a couple years - works GREAT, love the Mini and that display. The Cinema Display has Power for a Laptop, USB connector and a Mini Display Port connection on it.
I am a Guitarist / Songwriter and I use Pro Tools a lot. So I thought I would invest in the new Lightning Display for my Mac Mini. I would get the extra ports for Firewire, and USB, as well as now I could "Daisy Chain" my old Cinema Display off the new Lightning Display.
WHAT A PAIN IN THE BUTT THIS HAS TURNED INTO !!!! I have honestly spent more than 6 hours trying to find adapters or ways to make these monitors BOTH work at the same time with the Mac Mini ( you know, a Dual Monitor Setup . . .)
HELP !!!
1 - If I could find a HDMI MALE to Mini Display Port FEMALE adapter, I would run it on the HDMI interface - apparently no such adapter exists.
2 - You apparently can NOT daisy chaine the Cinema Display off the Thunderbolt Port on the new Monitor ( silly that that does not work, but it does not )
I am really stuck here - how do I get these monitors to work as "Dual Monitors" on the Mac Mini ???
Thanks !

The HDMI port won't work for a 27" monitor, it maxes out at 1920*1200...
Supports dual simultaneous displays -- 1920x1200 on an HDMI display or a DVI display using the included HDMI-to-DVI adapter and 2560x1600 on a Thunderbolt or Mini DisplayPort display or even a VGA display (with adapter). Thunderbolt is backwards-compatible with Mini DisplayPort-equipped displays as well as adapters that are compatible with Mini DisplayPort (DVI, VGA, dual-link DVI and HDMI).

Cinema display won't turn on

So my cinema display will not turn back on if I have it on, remove the cord from computer then try to put the cord back in. However if I put the usb back in and put my mouse in the cinema usb port the mouse still works. I restarted my computer and the display turned back on but I am afraid of ever taking the cord out again. My main computer is a MacBook Pro.

I have an early 2011 MBP and a 27 inch Cinema Display. Sounds like I am having the same issue. So far, no solution.
If I unplug the MiniDisplay port cord (All Original Apple cables) from the computer, when I try to replug in the MiniDisplay Port cable - the Cinema Display does not activate. I must try several unplug-replug ins to get the Display to light up. Usually takes about 10 attempted unpluggings and replug attempts for the display to come to life.
An SMC reset - has not effect.
I am now on my second Cinema Display - My first display was replaced at the Genius bar - they said it had a defective "logic board". The second display - operated normally for about 6 months, but over the past month has been exhibiting these same problems. I still have a bit of time before the one year anniversay for the Display so the warranty is still valid. Given that this is the same issue that happened with the first display - I guess I will need to buy the extended warranty. Don't like the idea of having to pay to have this problem fixed on a regular basis.

Cinema display has lit on, black screen

Hi everyone-
I have been searching the forums on a fix to the issue I am having. I am currently using a 17" MacBook pro (2006) and have a 22" apple LCD cinema display (from 2002) as my primary display. I use both at the same time. I have never had an issue with either and originally bought my display brand new in '02. Just yesterday as I got back to my desk, I tried to wake my system up, with the MacBook pro running fine and the 22" keeping the black screen. The light stays on underneath however. After shutting down, restarting, unplugging, etc the screen would not work the way it normally does. Every once in a while the screen would turn on, but was dark. When the screen is black, the light underneath is bright. When the screen would display, the light was faint. It would go back and forth between on and dull and completely black. The light continues to stay on when connected to a power source. It turns off when disconnected from power, and no matter how long I wait to plug it back in the light turns back on.
Thanks everyone for your help!

That's what I thought the situation was.
With the 22" "out" and as your primary screen how are you able to run since the menu bar would be on the screen you cannot see?
I think, for the moment, you need to make your MBP your primary. Hopefully if you disconnect the external 22" (may have to reboot) your MBP should become the primary. Then go into the Displays system preferences and make sure it is the primary with the Arrangement tab (move the little menu bar on to your MBP screen in Arrangement).
Now, at least you can control the Displays prefs for both monitors. If you reconnect the 22" (again may have to reboot) click detect displays and gather windows to get the Displays prefs for the blacked out 22" on to your main monitor (which is now your MBP).
Check the resolution and refresh rate. If they are ok then again I still think there is something wrong with the 22". But it couldn't be definitively be determined unless you could connect that 22" to another machine.
After thought: Your definitions of "primary" and "secondary". Maybe they don't agree with my definitions. I specify the "primary" monitor as the one containing the menu bar. Is that your definition? If so my original question about how are you able to run without seeing the menu bar on the 22" stands. But it occurs to me that your definitions may be that you still keep the menubar on your MBP but just work with the 22" most of the time.

Macbook crash on sleep after disconnection from cinema display

Hello,
I bought a black macbook core 2 duo a few months back as a replacement for a 1.5 GHz 12" powerbook G4, and I'm beginning to wonder if I made a terrible mistake as the Macbook frequently crashes on sleep which has caused a major disruption to the way I use my computer.
My work pattern involves pulling the computer out of its bag and opening it for between a few minutes and a couple of hours, before putting it back to sleep by closing it and shoving it back in its bag again, usually in a hurry, and usually several times each day. If I'm working at my desk, I pull it out of its bag, plug a keyboard, mouse and cinema display into it before waking it in lid-closed mode via the keyboard or mouse. I later sleep it via the power key, before immediately disconnecting the cables and putting it back in its bag.
The powerbook used to cope with this admirably, sometimes for two months at a stretch between restarts, and always with many applications and windows open. I had learned to expect that when I open the lid of my computer everything is there just as I left it, and more importantly that I didn't need to worry about saving everything before closing the lid.
The Macbook frequently crashes on sleep (regardless of whether I close the lid, use the key or menu or leave it until it sleeps itself), and have I narrowed it down to something that usually happens on one of the first few sleeps after I disconnect the cinema display. The macbook's backlight goes out on sleep but the display does not switch off (it can be seen, frozen as it was, if a light is shone on the display) nor the hard disk spin down, and the only response of any sort I can get is I can switch the white LED on and off by opening and closing the lid. This behaviour has always been the same regardless of whether safe sleep is enabled or not, although I have disabled safe sleep as I do not have the time or inclination to sit around waiting for 15 seconds for the disk to stop spinning each time I close the lid.
My question is, is there something wrong with my computer or is this normal for Macbooks where an external display is used? And if it is normal for macbooks is it something that is likely to resolve itself with future MacOs or firmware updates, or is it more fundamental than that?

Hello again,
It is hard to suggest something to do in this case, since intermittent issues are really difficult to diagnose. If I were you, I might try doing an Archive and Install from the install dvd that came with your macbook, as well as verifying the drive using Disk Utility on the install dvd. These are just suggestions and I don't know if they will change anything, but at least Apple may get more info out of knowing these were done to try and resolve the issue. If Archiving and Installing doesn't fix the problem (an OS software problem) and disk utility doesn't report any problems, it most likely warrants a trip to Apple. You definitely shouldn't have to put up with worrying about whether your computer will work or not every time you close the lid.
