Cinema Display backlight control

Hello,
for a kiosk application I would like to turn off the backlight when no vistors are present, to conserve power and the backlight. I have the remote sensing and everything else in place (running Adobe Director), but how can I turn the backlight off and on remotely? – Shades.app etc. don't do the job, because they just "blacken" the display, without actually affecting the intensity of the backlight itself.

...found my own solution. I let the display go to sleep using the energy saver ("Put the display to sleep when the computer is inactive for...").
To wake up the display, I used zScript to make Director scriptable, then sent a "key code 53" command to the system events application. This simulates a key press (in this case the "escape" key) which wakes up the display. Took a couple of hours of fiddling, and the zScript xtra costs $$$ if used commercially. But the demo works fine for my non-commercial project.

  • HT4279 cinema display backlight repair

    I have a 27" display that the backlight seems to be failing on.  Some mornings the display comes on just fine but others it either fails to come on or it comes on very dimly.  I suspect the LED backlight may be on the verge of failure but was wondering if anyone had any experience with Apple repairing these (including some estimate of cost?).  If you power off the monitor and restore power, it comes up fine nearly every time.  Have not upgraded to Yosemite on this computer yet due to issues (Safari crashes) on the newer version.  I would be willing to repair the monitor myself but if it's not about 1/2 the cost of a new monitor I would probably just have Apple do the repair. 

    Since you confirmed that it is not the Mac. I requested that your posted be moved to the Cinema Display forum

  • Dual 20" Apple Cinema Displays brightness control

    Hello all,
    Finally added a 2nd 20" Cinema Display to my setup. When I first got the new display hooked up (used from eBay, but in great condition) I noticed that it was pretty dark so I went to adjust the brightness... but the buttons on the side of the display didn't work and there was no brightness slider on the preferences pane for that display. The primary display DID have the brightness control.
    Does anyone know what might be causing this? Any help would be greatly appreciated.

    I've been trying to figure out why I couldn't change the brightness on the 20" cinema display connected to my MacBook Pro and now I know the reason. Thanks for this question and answer.
    Shouldn't such a simple and necessary thing be made clear in the MacBook Pro manual?

  • 20" Apple Cinema Display - Dim Backlight Fixed! (Sorta)

    Well... as many other Apple Cinema Display owners have experienced the infamous dim backlight with the "short short long blink" - I have some wierd news to report...
    Mine got fixed last night on total accident.
    Last night there was a huge storm in my area and there was a lot of lighting and massive down pour of rain, stay with me honest I have a point.
    My G5 was on last night while I was asleep in the other room within visual range of the display. There was a lighting strike on my property about 20' from where my office is which is on the corner of the house. The lighting hit the tree and send an obvious surge of power into my house and zapped some electronics.
    Wireless router, cable modem, and thermal label printer all bit the dust - and the USB ports on the back of the ADC display. I jumped up from the sleep and saw the monitor light up out of screen saver because the house shook so hard. I ran over to the machine and tried to move the mouse and keyboard and no go since the USB ports are burned out, but the monitor was FULLY LIT UP. I have unplugged the monitor and plugged it back in multiple times, turned the machine off and let it sit and it still is working great minus the USB ports.
    My hunch is this... because of the dead USB ports which are no longer drawing any power, is it possible that the USB ports are the cause of the "short short long blink"?
    My screen went dead initially when it was in a deep sleep mode and NEVER came out of it until now.
    So basically what I am suggesting is that someone try and unhook the USB (if it is even possible) and see if that helps with their display - if not, I guess I am just lucky and my Apple Cinema Display is just lucky to not have fully bit the dust.

    We can't answer that because that's going to depend on who you talk to. By the book, AppleCare covers defects and not accidental damage, so you could get a No answer if they determine it was not due to a defect. But realistically, sometimes you talk to someone who decides to use their ability to authorize an exception and get it fixed anyway. The only way to find out is to call AppleCare.

  • Backlight bulbs in Cinema Displays

    Does anyone know how many bulbs there are, where to get / replace, part number, etc. I have a 20" Apple Cinema Display, and the backlight is dimming on the top half.

    Does this thread contain anything useful?

  • Apple Remote Desktop CANNOT observe/control/curtain 30" Cinema Display

    Apple Remote Desktop CANNOT observe/control/curtain 30" Cinema Display. All my other pc's (G4, G3, titanium, 17" Powerbooks and Macbooks) can be observed, using identical settings. i figured out that it may be the graphics card while trying to Microsoft Remote Desktop Connect to the Macbook running XP, the system crashed due to the (well known as really bad) ATI mobility XP drivers provided by bootcamp. So i quess the problem is the dual link in my G5 running on the 30". All the other remote desktop commands run fully ok. i just cannot get visual feed.
    Any thoughts??
    Thank you all in advance

    I've had this problem, too, recently. I have two G5s running 30" displays, I'll describe my situation - it may come down to your video card.
    When I try to connect to one of the G5/30" on my network (a PowerMac 7,2, 512MB, running a GeForce6800 Ultra), it sporadically gives me the same non-visual problem you're having. But every now and then, I can connect, and can't figure out why. A lot of times in the ARD multi-observe window, it reports that this machine is maxing out the memory (98.7%, putting it in the red)
    However, when I try to connect to another G5/30" on the network (a PowerMac 7,3, 512MB running an ATI Radeon 800 XT), I DO get a visual.
    Maybe others know of known deficiencies in ARD/NVidia connections? Or maybe it has to do with the paltry RAM in the machine?

  • Can't control volume on LED Cinema Display from keyboard

    I have a LED Cinema Display attached to my Mac Mini. The volume control buttons on the keyboard don't work anymore. The only way I can change the volume is to use the volume control on the video I am watching. I tried the headset trick on the output port on the Mini, and now that works with the volume keys. But, the display volume is still not working. Any hints?

    The reason why that has happened in the first place is because MAC OS, is programed to not adjust the volume through an HDMI interface. If you have the volume control shown on the upper bar like i do, it appears light grey.When you click on it you cannot move it up or down. This is of course what the keyboard controles for volume. It does not control the program.

  • Controlling Brightness on Dual LED Cinema Displays

    I got my mac pro and 2 x LED cinema display yesterday, very pleased with the whole setup (ordered a couple of extensions for the displayport cable after looking around in threads on here too). Something that bugs me a little though is that it seems only possible to control the brightness of the display connected to the graphics card in slot 1. using f1 and f2 adjusts this display's brightness but not the secondary monitor, likewise the system preferences display panel shows a brightness slider for each display, yet both sliders adjust the brightness of the same display.
    I assume this is a software issue and will be fixed either in the next build of leopard or in snow leopard, but am just wondering if anyone has found a workaround / some kind of keyboard shortcut I'm missing or anything?

    You are not alone:
    <http://discussions.apple.com/thread.jspa?threadID=1988252&start=0&tstart=0>
    There is one report (Filchescat) of it working correctly (apart from the Windows 7 user, whose brightness keys control three 24" displays).
    I don't see how Apple can make independent brightness control of external displays work from the computer. The brightness is controlled via the USB cable. Unless each display sends a serial number through both its USB and display ports, how is the computer going to know which USB port corresponds with which display. System profiler doesn't seem to show serial numbers for displays or USB devices.

  • Controlling brightness on two 24" LED Cinema Displays

    I have an 8-core Mac Pro from this summer with two NVIDIA GeForce GT 120 cards and two 24" LED Cinema Displays. I'm running Snow Leopard 10.6.1, and when I try to adjust the brightness, the slider on both panels controls only one monitor. I therefore can't adjust the brightness of one of my displays. Has anyone found this?

    I filed a bug report at bugreporter.apple.com, and received a pretty quick reply:
    This is a follow up to Bug ID# 7222745. After further investigation it has been determined that this is a known issue, which is currently being investigated by engineering. This issue has been filed in our bug database under the original Bug ID# 6828443. The original bug number being used to track this duplicate issue can be found in the State column, in this format: Duplicate/OrigBug#.
    Looks like I'm S.O.L. until they fix this!

  • Brightness Control and 2 x 24" LED Cinema Display

    I think I've discovered a bug with the Display System Preferences panel.
    I have a new 2009 Mac Pro with one ATI 4870 and one Nvidia GT120, each having a 24" LED Cinema Display attached. When I keyboard brightness buttons (F1,F2), only the one display changes brightness. When I use the sliders on the Display System Preferences panel, both sliders control the one display. So I can change the brightness of one display 3 different ways, but no way to control the other (or both at the same time, which is most desirable).
    What is even more interesting, is that the controllable panel changes depending on which monitor's USB connector is connected into which USB port and in what order they are connected. After trying different USB combinations, I once got the slider on the left screen to control the brightness of the right screen, and vice versa, but the controls are seemingly randomly reassigned on system sleep, and I havent been able to duplicate that behavior since.
    What is the best way to report this? It appears to be a bug in the USB code associated with the brightness sliders and the Display Preferences panel. My desired behavior would to have the keyboard buttons control the brightness of both displays at the same time.
    Thank You

    No problem with my 24" and a 2008 Mac Pro with an nVidia GE120. I'm betting that the problem isn't with the monitor but with the video card. I also have a unibody Mac Book Pro and discovered the color shifting problem without any monitor attached. It started occurring when I used my Huey Pro Pantone monitor calibrator on the LED display of the MBP. Recalibrating the display exposes the color shift. Putting the monitor back to the shipping calibration makes the display problem go away completely.
    At the same time, I never noticed any problem on the 24" cinema display before calibrating it, and exposing it to the hardware monitor calibrator exposed a way out of gamma color. After recalibrating the monitor in hardware, the picture is utterly flawless - best I've ever seen on a display of this size. I think the Apple software calibrator is a piece of junk and I suspect that it messes with the monitor in unhelpful ways. I'd suggest having the monitor professionally calibrated and see if that cures the problem.
    Also, it will be interesting to see whether anything in the 10.5.7 update fixes any display issues being reported prior to the release yesterday.

  • 27" LED Cinema Display, no brightness control

    I have a 27" LED Cinema Display that has the Mini DisplayPort cable and I am plugging into a MacbookPro 15" with a thunderbolt port. When I go into System Preferences there is no brightness control or ability to turn off automatic adjustment for the LED display, just the computer. I have the usb port plugged in as well. I have seen previous updates to fix this for earlier versions (10.6) but that didn't work on my OS X 10.8.2. Is there anything to remedy this? The automatic adjustment of brightness is very distracting and I would like to have control of the brightness of my monitor.

    FINAL NOTES
    It’s possible that the issue might simply be resolved when applying both a Software and a Firmware update for the LED Cinema Display. If you haven’t already, please download and install the following to see if these updates resolve the issue:
    http://support.apple.com/kb/DL1338
    http://support.apple.com/kb/DL1107
    Secondly, if you are using Mac OS X 10.8 (Mountain Lion) or Mac OS X 10.9 (Mavericks), please try this additional Software Update for the LED Cinema Display if you haven’t already installed it:
    http://support.apple.com/kb/DL1613
    Additionally, my research into other customers’ cases with these issues (brightness controls and USB functions not behaving correctly) regarding the LED Cinema Display shows that the following method might fix your issue: When connecting the affected LED Cinema Display into your Mac Pro, first plug the USB connector into the Mac, then plug the Mini-Display connector into the Mac, and finally re-open System Preferences to see if the brightness controls have returned.
    That mentioned just previously is worthless for those with an updated operating system but is mentioned regardless.
    As it works out those installers will not allow installation and merely state that you don't need this software in updated systems.
    They require that you make a brand new OS installation to be of any effect and are included in Software Updates.
    They are worth a try if all else fails.
    You should also try Disabling your Bluetooth "Discoverable" setting.
    The Discoverable Bluetooth setting seeks to establish a wireless USB connection and depending on your RF environment, can become very busy if not conflicted. (can override a wired USB connection)
    Last but certainly not least.
    Do NOT connect your monitor USB through a USB hub.
    Internally your monitor has a USB hub.
    Connecting a USB hub TO a USB hub is just asking, (if not blatantly begging), for problems.

  • 27" Cinema Display - No Brightness Control

    I have read over all the threads here and the internet.  I have an iMac (black back) that my 27" Cinema display is connected to.  USB and Displayport are both connected.  Everything appears just fine.  However, I cannot adjust the brightness on the Cinema display.  I have tried everything.  I even hooked it up to my Macbook Pro early 2011 model.  Still the same issue.  There is no brightness slider.  The slider only appears for the native display only.  Never the Cinema display.  What am I missing?
    Running Lion on both machines.

    USB cable is connected.  It's not an SMC issue.  I have tried this on 3 iMac's and 1 2011 MacBook Pro.  Same issue on all machines.  Cinema display does NOT have brightness control.  Only the native screen. 
    Tried on OSX Lion 10.7 and  Snow Leopard 10.6.  Tried loading the 1.0 Cinema display firmware update.  Won't install on Lion and states it's not require on Snow Leopard 10.6.
    Any other suggestions out there?  The display is full brightness it seems and it's annoying as crap.

  • Default Brightness On 23' Cinema Display

    I'm attempting to calibrate my monitor (purchased six months ago). The calibration software (Datacolor Spyder 3 Elite)recommends setting the brightness to the monitor's "default" level before calibrating. There's no reset button or key combination that I can find to do that, but the user manual says I can disable the brightness control (which I assume means it gets set to default) by clicking on Apple > System Preferences > Displays > Options. However, there's no Options tab in the Displays preference window. I thought I was on the right track when I read a suggestion on disabling the power button by holding down the Command + Shift keys when clicking on Displays, but this didn't get me to an Options tab either.
    How do I return to the default brightness setting?
    Any help is appreciated.
    Don

    Most 3rd party displays have many settings that can affect the calibration. The "brighness" setting doesn't always mean the same thing. That's why it is recommended to set everything to default.
    On a Cinema Display, you can only adjust the backlight intensity. The default setting means nothing. Just set it to a level that matches your environment and calibrate.

  • Troubleshooting 24" Cinema Display problem

    I have a 5 year old 24" Cinema Display connected to a Mac Pro using Mini DisplayPort. Several days ago I connected a Kanex Mini DisplayPort and USB Extension Cable. Everything was working fine until yesterday when the display faded to black while I was working. I tried plugging the monitor directly into the Mac and it seemed to be fine. Later on the same problem happened. Now I am unable to get any video on the screen. I tried a different monito and that is working fine so I know the graphics card is OK.
    Any ideas about what could be wrong? Is this a fixable problem? Did the extension cable fry my monitor?

    The 5mm LEDs that I used for the initial repair can be purchased from any electronics component supplier. Avoid Radio Shack at all costs. I wouldn't recommend using 5mm LED though. I've purchased some 5050 SMD LEDs for the next rendition. I will report back later in the week with my my results and possibly some photos. It's not somethign you want to attempt unless you're confident in your soldering skills. You'll also need to do a little math to figure out how to configure the LEDs and give them the right resistor.
    Here are some photos of the 5mm LED job. I parralelled 3 strings of 8 LEDs wired in series and powered them directly from the 24v rail of the power supply. These LEDs are held in with hot glue. On the next repair, now that I know its worth while, I'll use the backlight driver from the logic board which will give me brightness control again. Pardon the mess, I had been working on wiring up  that strip for a couple of hours. It really helps to have an adjustable lab power supply on the bench to test as you go. Also, note the hot spots in the bottom right and left corners of the screen. They are caused by misaligned LEDs.

  • Cinema Display 23 aluminum and Windows 7 64

    I have an Apple Cinema Display on an Alienware Auora i7 980x running Windows 7 64. I have an nVidia Quadro 4000. In the nVidia Control panel the monitor shows, but not in device manager. One of my monitors shows up in Device Manager, but not in the nVidia control panel. I tried installing the WinACD version 0.4.6 but get the mesage that the "installation was interupted"
    I have two Dell monitors that show up in Device Manager, but one is missing from the nVidia control panel. Although the Apple Cinema Display does show up in the nVidia Control Panel, it is not sown in Device Manager
    I have contacted nVidia, but was hoping to find out if there is a driver for the Apple Cinema Display.
    Any ideas?

    Hello again,
    After speaking to an Apple Genius, it seems the solution was to update the firmware for the Cinema Display. Since I have done this, the monitor appears to behave better.
