Adjusting brightness with two 24" LED Cinema Displays

I'm wondering if there are any other Mac Pro users out there with two 24" LED Cinema Displays? If so, are you able to adjust the brightness of both displays? For me, no matter which brightness slider I adjust in System Preferences, only the brightness of one of the displays is adjusted.

If you have this problem too, please report it to <http://bugreporter.apple.com/>. My original Radar bug was #7222745, and it was found to be a duplicate of #6828443. Based on the IDs, I'd say this has been a known issue for at least a year.
Thanks,

I filed a bug report at bugreporter.apple.com, and received a pretty quick reply:

  • 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 am using logitech G19 mouse and Naga Razer Epic, my current suspect that is their official driver which make my OS X 64bit kernl go nut. Does Logitech Control Center work for later version of their products such as G19?
    If I plggued in the G19 without installing their official gamepanel software, The heyboard still work, volume control slider works like a charm. I just get no advantages from the LCD screen (kind of pointless).
    If I install the razer mac driver, I keep seeing error log in console for the kzcorengineand razercorenginer process.
    Idid clean install of Mac OS X and have not experienced freeze except once when I was plugging in my 500gb transcend external drive. This Ext. Drive require two usb slot for power and transfer data.
    I am not sure if the freeze was coincidental or related to the transcend external drive I used. I did a directory permission repair and a repair to the mac drive, how things seems to stabilised.
    However I want to take my test further to install office 2011 to see if it cause those random unpredictable freeze again.
    Sigh, I paid $200 for such a good keyboard, but they have bad apple support. I dont like the apply ketyboard and magic mouse. It's immpossible to touch type on and even harder to play any game at all.
    Wayne, when you use your logitech product, do you install the product specific driver for each product plus LCC? or you just install LCC.
    Thank you

  • Two 24" LED Cinema display and getting audio from both

    I have two 24" LED Cinema displays connected to a MP. Is there a way to get the audio to play through the speakers on both displays at the same time? I can easily switch the USB audio to either display, but I cannot figure out how to play audio through both at the same time. Thank you for the help,

    You can hijack the audio from any application, or the system audio, with Audio Hijack Pro
    <http://www.rogueamoeba.com/audiohijackpro/>
    You can then use its Auxiliary Device Output effect to send the audio to multiple devices.

  • Will my MBA work with the new LED Cinema Display

    I have a first generation MBA, model identifier MBA 1.1, and want to know if my mini display adapter will work with the new LED Cinema Display. I believe I have a micro-DVI that is different from the new MacBooks and MacBook Professional models that have a new Mini DisplayPort. If anyone is using this old MBA to new LED Cinema Display combination please let me know.

    Scott,
    The new display isn't shipping from Apple until some time in November so the only direct feedback you'll get is from anyone that's been to the store and played with the demo unit.
    With that being said, it would appear (based on the system specs and requirements, posted on the site) that the new display requires the new adapter type that's found only on the new MacBook, MacBook Pro and MacBook Air.

  • My macbook is back from repairs. It is not working with my apple led cinema display. It was working prior to the repairs on the laptop. Is there a setting I don't know about that might have been changed?

    My macbook pro is just back from repairs.  It is not working with my apple led cinema display. I have followed the directions in the cinema display manual.  am I missing something?

    Take a look at the Displays preference panel to see if everything is ok, particularly the resolution and refresh rate.  Displays will probably try to put the panel for the ACD on the ACD where you won't see it.  So click "Gather Windows" to get the ACD panel on to your macbook.
    One more thing, make sure you fully seated the mini displayport plug.  They can be sneaky little devils in that they need to be fully pushed in.

  • MBP with New Apple LED Cinema Display

    Does anyone know whether it will be possible to use an early-2008 MacBook Pro with the new Apple LED Cinema Display? I know that the new display is made specifically for the latest MacBook, MacBook Pro, and MacBook Air with the mini-display port, but I wondered whether there will be some type of adapter offered so that an older MacBook Pro may be used with the new display (or whether this is even possible).
    Any input is appreciated.
    Joe

  • Photoshop issues with MBR and LED Cinema Display

    Hi,
    I have my MBR 15" connected to a 24" LED Cinema Display. In Photoshop, when dragging windows to the secondary display (the Cinema Display) they turn immediately black. If I drag them back to the main monitor (the MBR) they will show up normally.
    Now, if I change the main and secondary displays (1st-CD; 2nd-MBR), this will happen again on the secondary.
    I really need to have both displays working with Photoshop. Does anyone know a workaround to this? 
    Thanks in advance,
    Jorge

    Sorry, forgot about that. It's Photoshop CS6, already updated to be Retina capable (version 13.0.2).
    I'm going to check for further updates.

  • Problem w/ two 27" LED Cinema Displays on ATI 5770 MacPro

    Attempting to connect a second display to a mid 2010 Mac Pro. There are two mini-ports + a DVI on the 5770 card. Currently I have a single 27" LED connected using one of the mini ports. The computer isn't recognizing the second monitor in the other mini port. I used to have an older 24" LCD Cinema display running successfully, using the DVI port on card with a powered adapter. That configuration isn't doable with a newer 27" given the output from it (not the older style video cabling, but rather the mini display port. Would appreciate any suggestions on how to get the two 27" monitors running together.

    Hey turbostar, finally a chance to get back to you, sorry about the delay.
    I had already tried both ports with no success on the second monitor, but when I moved the primary monitor to the second port and it worked... it it got me to thinking maybe the power outlet was bad if not the monitor itself. Indeed that was the issue. The second monitor was plugged into a power strip in which one of the six outlets on it was not working. Replaced the surge power strip with a new one and all is good.
    Thank you for your time and help.

  • Using mac mini with late 2008 LED Cinema DIsplay

    Have the mac mini, 2.5 ghz. There is one Thunderbolt port, I am using that to use my 2008 (late) Apple Cinema LED Display. This display is supposed to be for the macbook pro, but I am using it on the mini...the power magnet cord is just dangling there and I plugged in the usb and the display cable into the thunderbolt (TB). Since I used the one TB port for the display, how can I hook up future drives, etc? Can't find a TB hub, maybe they will come someday too?
    Question, is there any problem using this display on a mini and just not use the power connector?
    - Kevin

    It can be done the problem is the hdmi port does not support the full native 27" resolution. It will go up to 1920x1200. Even then you need a converter.
    http://www.atlona.com/Atlona-HDMI-to-Mini-DisplayPort-Converter-and-Scaler.html
    You could also use a displayport splitter.

    And this one only seems to support 24" cinema displays.

  • Two 24" LED Cinema Displays from 2009 Mac Mini?

    I have been using two 24 inch Samsung's with a Mac mini for about 6 months and it's been great until one of the monitors failed me last week. After some research I purchased a new 24" LED ACD and it's a beautiful monitor that blows away my other 24" Samsung. I'm thinking about getting another 24" LED ACD and my question is: Has anyone connected 2 24" LED ACD's to a Mac mini using: http://www.atlona.com/Atlona-DVI-to-Mini-DisplayPort-Converter-p-17859.html
    My plan is to use the mini display port to connect one ACD and use the Atlona Converter to connect the other ACD through the mini DVI port on the Mac Mini. I have the Atlona converter ordered and it will be here early next week and I'll report back on the results unless someone else has already done this and knows it works.

    Just one further question, though - doesn't that mean I lose out on other uses for the Mini's only Thunderbolt port?
    No, because Thunderbolt can be daisy chained. Just make sure that whatever Thunderbold Drive Enclosure you get, has dual Thunderbolt ports so that you can chain your second monitor to it.
    see > Displays: Mini DisplayPort display must be last in a Thunderbolt chain
    Also, can I ask why you suggest putting the 20" on HDMI? If it came to running a single monitor + Thunderbolt RAID setup, I'd like to have the 23" on the HDMI.
    Mostly because the Thunderbolt/Mini DisplayPort supports higher resolutions than the HDMI port.
    HDMI to DVI only supports 1920x1200
    Thunderbolt port supports 2560x1600
    Would that be problematic?
    Not as long as the 23" monitors native resolution is 1920x1200 or less.

  • How do you connect two 27" LED Cinema Displays together?

    I currently have one screen connected to my MacBook Pro 2010.  How do I connect the second screen if I only have one Thunderbolt port?

    I Think they can be daisy chained.check your manual for more info to see if your Mac supports this

  • Select Default iSight Cam with Dual LED Cinema Displays

    Hello
    I have two 27in LED Cinema Displays, both of which have iSight Cameras.  When I try to facetime, by default, the right monitor camera turns on, but I want to use the left camera.
    How do I select which camera on which monitor I want to use?  Both monitors are connected via thunderbolt.  I'm using OS X Mavericks.
    Thanks!

    You can try the old trick of first launching a camera app that you do NOT want to use - QuickTimeX > New Movie Recording perhaps - to have it engage the ONE display iSight camera.  After you can see that your camera is engaged with the unwanted app, you can hide that app if desired.  Then launch FaceTime and see if the other connected camera is accessible to FaceTime.
    If FaceTime cannot then recognize the second Display iSight, check your System Information utility to see if your Hardware > USB > USB Device Tree recognizes both Display iSights.  If the device tree recognizes only one Display iSight, your lowest cost workaround may be to connect a Mac-compatible webcam to one of your available USB ports so it is recognizable .  The external camera may then be selectable in your FaceTime menu without the two-application trick.

  • 24" LED Cinema Display not working on new MacPro with GT120 graphics card

    Dear All,
    I have recently purchased a new Mac Pro Quad (2.66 GHz, 6mb DDR3 1066 MHz RAM) with a 24" LED Cinema Display. When powering up the computer for the first time, the display was blank. I swapped it out with a 23" Cinema HD Display, and it worked fine, so I thought it might be the LED Cinema Display itself. However, when I tested the LED Cinema Display on my MacBook (Model 5,1; INTEL Core 2 Duo 2.4GHz), it worked like a charm.
    Has anybody seen this behaviour? I'm assuming that it's a software issue (since the GT120 DVI adaptor works with the Cinema HD Display, so the mDVI adaptor should be good). [I also rebooted and wiped the PRAM and NVRAM, to no avail.]
    Any and all help would be appreciated.
    Best,
    Drew

    Thanks for the reply--I've done that before, for sure.
    An odd thing did happen when I reset the PRAM & NVRAM a second time--it worked. Maybe I did it wrong the first time? Anyway, it's working perfectly now. Many thanks.

  • Quadro FX 4800 graphics card & 24" LED Cinema Display

    I just ordered a new Mac Pro (Two 2.66GHz Quad-Core Intel Xeon; 12GB (6X2GB) RAM) with the 24" LED Cinema Display and a Quadro FX 4800 graphics card.
    The Cinema display only has a Mini DisplayPort connector and the graphics cards only has two Dual Link DVI-I connectors.
    I have read that there are two adapter options available:
    1. Gefen DVI to Mini DisplayPort Adapter
    2. Atlona DVI to Mini DisplayPort Converter - Model: AT-DP200
    I have also read good and bad reviews of both products.
    My question is this: If I use one of these adapters to connect the 24" display, will I be losing all the benefits of the Quadro FX 4800 card?
    Thanks for the advice.

    1. Gefen DVI to Mini DisplayPort Adapter
    2. Atlona DVI to Mini DisplayPort Converter - Model: AT-DP200
    I have also read good and bad reviews of both products.
    The only bad things I have read is no dual-link DVI support and no HDCP with the Gefen.
    My question is this: If I use one of these adapters to connect the 24" display, will I be losing all the benefits of the Quadro FX 4800 card?
    No. The adapter just converts the output video format. It will not affect the behaviour of the graphics card,
