Brightness Shortcut - Dual Displays

Anyone know of a way to modify the keyboard shortcut (F14/F15) to change the brightness of both ACD's at once Vs. the default behavior of just modifying the main screen?
Thanks in advance!
Michael

There is a bug in the Apple Cinema Display or the iMac that controls it.
THE CINEMA LED DISPLAY BRIGHTNESS CONTROL SLIDER IS MISSING.
1. The apple support did not know anything about the problem.
2. It happens over and over on both of my iMac/Cinema systems.
3. I fix it, and then it happens again.
This time, after numerous unsuccessful trys to get the brightness slider to work on the Cinema Led display, I tried holding both keys down at the same time:
"Command" +"F1", and low and behold, up popped my Display Preferences WITH THE BRIGHTNESS CONTROL/SLIDER ENABLED!
*************APPLE SUPPORT, PLEASE TAKE NOTE AND GET THIS PROBLEM FIXED PRONTO. IT IS VERY FRUSTRATING TO HAVE TO FIX THE SAME PROBLEM OVER AND OVER!*******************

  • Brightness Keyboard Shortcut - Dual Displays

    Hi guys,
    Posted this in another forum and did not get an answer so thought I'd give it a try here. I've got a Mac Pro with dual 23" displays. Anyone know of a way for the keyboard shortcuts (F14/F15) to affect brightness on BOTH displays instead of just the main one?
    Thanks in advance!

    Nope. Not it. I managed to set it so F1/F2 **AND** Fn+F1/Fn+F2 adjust the screen brightness. I can't for the life of me find where I *defined the keyboard shortcuts* for the screen brightness. I know that I did it, I just wish I'd written down *where*.
    The problem I'm having is that the system F1/F2 functions are overriding application-specific shortcuts. NOT the "Function/Fn" stuff.

  • 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.

  • Dual-Display Tools for Mac OS X ???

    I think this question is more appropriate in some software section of the discussions but I couldn't find an appropriate place to put it.
    Anyway, the questions is, in Windows XP and Windows Vista there are some tools, (either provided within the software in the graphics drivers, or available through external 3rd party software such as UltraMon) that facilitate working in a dual display environment.
    I have Mac OS X now running on 2 x 20" displays and I am looking for some tool that offers similar quick tools and options like "Jump window to next screen" or "Maximize on second monitor", and a tool which might extend the dock to the second monitor. So that whatever is minimized in one monitor appears in the dock of that monitor rather than appearing in one dock.
    Also something that remembers which monitor the application was running on when it was opened before, so that the next time it opens up, it opens in that one rather than opening up in the primary monitor.
    This was all offered by a software called UltraMon in Windows XP, and I found it extremely handy when working on a dual display set up. Especially since I could assign keyboard shortcuts to all the tools and just by pressing some keys on the desktop I could jump windows to the next screen, or maximize, minimize on each screen.
    Does anyone know of an equivalent in Mac OS X?

    Unfortunately, there does not seem to be any Mac equivalent for UltraMon.
    Fortunately, MacOS has always been much better at managing multiple display setups than windoze ever was. You might take a look at "Desktop Manager"
    http://desktopmanager.berlios.de/
    which provides a lot of the virtual desktop features UltraMon offers.
    The biggest drawback in using multi display configurations in OSX has to do with the way applications are displayed. In windoze, every open app has its own "menu bar" that is part of the application window and, therefore, can "travel" with the window. On the Mac, the menu bar is always at the top of one display or the other and changes for the active application. Not nearly as convenient and one of the very few ways that windoze (IMMHO) is "better".
    There is a good utility that will aid greatly in overcoming this limitation. It's called DejaMenu
    http://homepage.mac.com/khsu/DejaMenu/DejaMenu.html
    and it will give you a popup contextual menu for the active application by "right clicking" anywhere in any of the app's windows.

  • Brightness shortcut keys not working in Windows 8 or 8.1

    I'm no longer able to use the brightness shortcut keys after I've installed the Lenovo power management tool in Windows 8 on a Ideapad U300s.
    When the Lenovo power management tool is NOT installed on the system, pressing the shortcut keys brings up the Windows UI in the upper left hand corner of the screen and the display bridghness is adjusted accordingly.  
    However, as soon as the Lenov PM software is installed, the Windows brightness indicator shows up ONCE and I can no longer adjust the brightness with the shortcut buttons.

    Welcome to the Apple Support Communities
    At the moment, there aren't any Boot Camp drivers ready for Windows 8, so it's normal that you have problems. Wait until Apple updates Boot Camp drivers, normally with a OS X update

  • Wacom tablet on dual display dual card setup...

    ...and the cards are as follows, one Geforce GTX 460 (nvidia driver), one Radeon x1650 (radeon driver) As such, I have to use Xinerama and not RandR for my dual display setup. I have configured the driver to use my main display (Dell CRT on GTX 460) and the cursor shows up where it's supposed to, but when I draw, the cursor "splits" into two, the actual cursor, and the drawing cursor. The regular cursor moves as if it's on my main display, but the drawing cursor spans both desktops.
    I've tried all kinds of things to make it work, no luck though.

    MisterAnderson wrote:Honestly no clue how to help you, but I am interested in your setup. Are you using the proprietary drivers for your nvidia card and the opensource radeon for your ati? How did you get this setup working? I've been trying for ages!
    If I remember correctly, I just used --nodeps and maybe --force when installing the nvidia driver, that way it didn't force me to uninstall the radeon driver when I install the nvidia driver. Then, look at my xorg.conf. there's no acceleration of any sort on the ati card, but I can use it for terminals and browser windows, text editors and the like. Can't watch flash videos on it though, and I don't think mplayer works on it either, I'm not at my arch box atm, so I can't verify that.
    Also, as mentioned in my opening post, no composting either. The same setup works pretty good in Ubuntu with a similar config, but no compositing there either, Unity clones 1680x1050 of my main 2048x1536 display, can't split the desktops, and I just end up using Xfce4 because it handles Xinerma pretty well.. I have to turn off the compositing extension in the config on arch to get X to even start up.
    :edit:
    back in arch, should note that whenever I install a new package, I receive this warning. Everything still works tghough as I describes. And back on topic, anyone have any clue as to why my tablet behaves this way?

    According to the copy&paste from wikipedia, HDMI should support higher resolution than 1920x1200. So the question is, does it aupport that on the mid 2011 mac mini. It says in the specifications
    "Mac mini is designed to work with HDMI devices that comply with versions 1.0, 1.1, 1.2, 1.2a, 1.3, 1.3a, and 1.4 of the HDMI specification."
    That should mean it should be able to support it, but I don't know : <

  • How do I use dual displays to have a full screen app on one monitor and another full screen app or the desktop on the other?

    How do I use dual displays to have a full screen app on one monitor and another full screen app or the desktop on the other?
    I want to have my itunes visualizer on my TV which is connected via HDMI adapter, and still have access to full screen itunes and my desktop on the main display.
    Any suggestions?  App downloads that can do this?  Please let me know.

    You can't do it.  This has been an issue since Lion.

  • Dual display color and other related issues...

    I have posted this on painter forums, though some of the issues coming together here are directly related to issues w/ Snow Leopard and dual displays. Thought I would try here....
    This is so bizarre. When I ever I run P11(I think this is going on in P10 too?) w/ the OS X (snow leopard, 10.6.2 on quad core Intel Xeon Mac Pro, 10 GB of RAM) menu bar on my Eizo(making it the main display), and the Apple Cinema display left as the #2 monitor, I get very annoying brush cursor artifcats left randomly on the Eizo screen after strokes. One cannot predict when the cursor will leave it's gray "marks", but it will do it, sometimes 5 strokes in a row, sometimes after 15 strokes or so? If I move my brush back over them, or change the image percantage view, they vanish, obviously new ones coming back, as I work.
    However I put the OS menu bar on the AC display, yet work back on the Eizo, this does NOT happen. No cursor artifacts. Well, at least I can summon the issue
    The reason I am doing this is Snow Leopard has bad color issues w/ dual displays (well documented, much to Photoshop CS4 users frustrations, and mine). Apple needs to fix it... but for me to see the right color on the Eizo(this is my main color and superior display), it needs to be the main monitor(menu bar) in 10.6.2.
    So, you can see my trap - Accurate color, or annoying cursor artifacts left on the screen (sorry, it really bugs me as I work) as I work in Painter.
    Attempted fixes: Trashed all of Painter's prefs, all of Wacom's Intuos 4(latest driver) prefs and software, switched plug ins on the back of the mac for the displays(lots of restarts), ran cache cleaning Cocktail and DiskWarrior, etc. -- no change, as I can duplicate the issue w/ the above set up. A sidebar or maybe be very related note: I have an iMac w/ max amount of ram (model not very old -- maybe 1 or 2 old) and I have had a long standing issue working on the iMacs we have had w/ this brush cursor artifact problem (in Leopard and Snow Leopard). I am on one monitor w/ the iMac, so you know here the menu bar is...hmmmmmmmm.....?
    Thanks!, T

  • Possible to do dual display with a mini?

    I have an early 2008 Mac mini (Intel) - with the standard DVI connector; using the supplied DVI/VGA adapter to connect to an LCD monitor.
    I'm just wondering if it is possible to use two displays with this model and if so, how do I connect the second monitor?

    Several ways of doing it in this thread:
    http://discussions.apple.com/thread.jspa?messageID=8335705&#8335705
    If you want to go the usb route, see also:
    http://eshop.macsales.com/item/Other%20World%20Computing/VIDU2DVIA/
    Be sure to examine the limitations of each method.
    (I'd also consider that your 2008 Mini likely has substantial resale value and that you might prefer getting a 2009 Mini which natively supports dual displays.)

  • Dual Display on Mac Mini

    Hi there,
    I want to have a dual display setup with my Mac Mini. There's also a twist. One of the displays is a regular monitor. The other display is a 46" TV. I am not too technically minded - is there a splitter or some kind of dual display "kit" I can pick up?
    Thanks!

    Which Mac mini? The new one has two video outputs on it, so two displays is not a problem.

  • Dual Displays and Windows XP

    Hello,
    I have a MBP with the Radeon X1600 graphics card. Under OS X I can run dual displays without a problem, either extended or mirrored. Using Bootcamp to boot to Win XP, I can only get the 2nd monitor to run extended, I can't get it to run mirrored. What really drives me nuts (short trip) is that I have run it in mirrored mode before when I teach. I go to the Display dialog box and "see" both monitors, but the only way I can get anything now on the 2nd is to run extended? I could update Radeon driver on the Windows side, but I thought BootCamp took care of that and I don't want to mess up my laptop?

    It is definitely best to reinstall anytime you make a major system change. You will have to do at least a windows repair although I am not sure if it will fully enable the dual core.
    Good Luck

  • Dual Display - help with Cinema Display for MacBook Pro where MB won't detect displays.

    I just got a Cinema Display (a1081 20") ("CD") off eBay to use as a dual screen with my Macbook Pro OS X 10.6.8 ("MB"). However, I can't get MB to recognize CD! I've tried power cycling both the MB and the CD with and without USB cord connected. MB won't recognize CD display in any situation. However, it is recognized in some capacity although I can't use dual display because the CD power button triggers MB to ask me if I want to restart, shutdown, or cancel.
    Any help is appreciated!!

    Have you tried smc and pram resets?
    Try Detect Displays in the Displays preference pane.
    Does the Displays preference pane Arrangement show two screens?  If so do click gather windows and check the resolution setting of the new screen.

  • Dual Display, 2 Monitors - Extended Desktop

    Hello Everyone:
    There isn't a clear cut answer or solution in connected a Macbook Air to 2 external monitors in an attempt to create an extended desktop. I have read older posts that it's either doable or not doable. My questions are the following:
    -Is it possible to connect a new Macbook Air to 2 external monitors for extended desktop purposes?
    -Some users have reported lag issues (mouse dragging , delays, etc.). Will this happen for sure with a Macbook Air or is it a monitor issue?
    -What's the best non-Apple monitor brand that would work best with a Macbook Air for dual display purposes? I've read that Dells have a problem in this regard.
    -What would be the advantage or disadvantage of using a dock station in setting up a dual display environment? Would this add to the lag, latency factor?
    I'm thinking of investing in a new Macbook Air, but I want to make sure I dont end up with silly issues - such as latency, monitors, etc.
    Thank you for all your help and advise.
    Best,
    G.

    Yes, extended desktop works with monitors set to differant resoultions. the Monitors pref pane allows you to select relative arrangements and rez of all monitors composing the extended desktop.
    personally I run a dell CRT at 2304 X 1728 @ 60Hz along with an NEC 6FG a 2048 X 1280 @ 60Hz off a radeon 9800pro on an MDD.
