Is there a shortcut to adjust brightness on dual LED display?

i have a 24" LED display hooked up to a macbook pro. the F1 and 2 keys adjust the brightness on my laptop display, which is dandy, and i can open the display preferences and adjust the slider for brightness on the LED display, but i'd love a keyboard shortcut. is there one? thanks!

There used to be a way in the old Quicktime to adjust the color or brightness of a video if it was too dark to view. It seems this functionality has completely gone away. Why?
QT is now two decades old and Apple is out to re-write its technology by making a clean break between the old and new. As such, QT X is in its infancy and has yet to reach a point it its development where Apple can refine the "extras" we all miss. My suggestion is to install the dual 32-/64-bit version of QT 7 and use it when you wish to access the A/V control panel. Both QT X and QT 7 can be installed/used simultaneously on the same Snow Leopard system. The QT structure is already embedded in your OS and only requires installation of the QT Player 7.6.6 for Mac OS X.6.3 and later. Note that the QT 7 Player is installed in your "Applications/Utilities" folder and should be left there to ensure proper updates. Also, if you have a valid QT 7 "Pro" key, you can key this player for "Pro" use.

Is there a shortcut to adjust icon spacing?

Is there a shortcut to adjust icon spacing without selecting 'show view options?'

Well yeah, I know about that, but what I am asking is: for example, I use the track pad and when you swipe two finger out the icons enlarge and vise/versa. Is there a short that would allow me to expand and contract the icon spacing similarly to the icon size?

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?

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.

Adjusting brightness on external LCD of MacBook

I have a Samsung Syncmaster 2033 connected to my MiniDisplayPort. The buttons on the side of the monitor have stopped working. Is there anyway I can adjust brightness/contrast and/or any of the other configuration settings for the monitor from OS X? Otherwise, is there a third party software out there that will do it?

Adjusting brightness without washing out an image

I'm using a ColorTransform to adjust the brightness of an image, but it's also causing it to look faded and washed out as I increase the brightness, even by just a small amount.
Is there a way to adjust brightness without getting this effect, or something that can be done to offset it?
(edit: using Actionscript 3.0, require code solution, not something in Flash IDE)

Hi and welcome to the forums....
I'm certain you can't do that in Aperture... Aperture is a pro photo management system with some excellent image adjustment features. But for what you describe you will need Photoshop or other such application.

Is there a way to adjust shadows in iMovie 11? WhenI adjust brightness it changes shadows also. If not is there free or low cost software available? My operating system is Lion.

You used the data. Verizon can not see what it was sued for. However your phone can see whats apps used the data. go to settings-data usage- there will be a place that says data usage cycle. line the dates up with your cycle. then there will be a bar graph below that extend bother white bars one all the way to the left and one all the way to the right. after those are extended below that will be a list of apps, there should be one that used over 2 gb and that will show you what app used that data in her purse

27" ACD as second monitor -- cannot adjust brightness

I've connected a 27" LED ACD to my 27" iMac as a second monitor, but the keyboard commands for adjusting brightness do not affect the cinema display. I understand a common cause for this is that the USB isn't connected, but mine is and I can verify it is working because I have an external HD connected to the USB port of the ACD, and the iMac recognizes that it is connected.
Also, if I go into Display Preferences then I do see the Brightness slider for the second monitor. This is currently the only way I can adjust the brightness of that monitor.

True, Unless there's a shortcut for that, the only way to adjust the brightness of the second monitor is by using the display preferences . same here with a MBP / 27" display.

How to precisely adjust brightness under Lion

Hi,
working with a Mid 2010 IMac and the Apple Wireless Keyboard it is obvious that brightness may be controlled by pressing both the "fn" key and the respective keys F1 or F2.
Under Snow Leopard I created a list of useful shortcuts to get familiar with the various extra functions. One of them was to press ALT + Shift + fn+F1/F2 to be able to adjust brightness in finer steps than with the a.m. regular tune. The background of my question is the adjustment of brightness in context with a monitor calibration using a colorimeter.
This ALT+Shift method doesn't seem to work since I upgraded to Lion (10.7.3). Any ideas or proposals are appreciated.

Right. Attempting to install or boot a version of OS X earlier than the one installed on the Mac when it was built is likely to fail: Don't install a version of Mac OS X earlier than what came with your Mac
The reason is that new Mac hardware requires new drivers that may not exist on previous versions of OS X.
If it shipped with Lion it might be able to boot Snow Leopard, since there was a period of time in 2011 in which computers produced with Snow Leopard were later shipped with Lion, while the hardware remained unchanged. This will work only if you did not update the Mac's firmware though.

Windows 8.1 Bootcamp wont Sleep or adjust Brightness

Hey Guys, I installed windows 8.1 via bootcamp onto my 2013 rMBP, 16gig Ram, Upgraded Processor, and I have two issues with it. 1. I cannot adjust my screen brightness, which is manageable but annoying. 2. It wont go to sleep. There isnt an option anywhere to adjust brightness or put it to sleep. The only option are to hibernate, shut down, or do nothing. It seems as though the sleep function just isnt available, nor is the brightness. I feel like thse two things may be connected, but I wasnt sure. I have browsed some threads, but nobody seems to have a find for 8.1 or these problems yet. When I try to sleep my computer (i.e. close the lid) it just shuts down, and I have to hold option to power up back into windows. If anyone has a solution, please do let me know:) Thanks!! Also I'm running mavericks fully updated, the newest bootcamp software and the newest bootcamp drivers, AND windows is fully updated.

I have the same issue. Any luck miller? When I close the lid on my Macbook, i have to power back up and use the OPTION key to get back to Windows 8.1. This issue just started after updating to Mavericks...
My brightness control does work fine.

By that I mean <command> + 1 for cyan, <command> + 2 for magenta etc. like Photoshop CS3 rather than <option> + 3 for cyan etc.
There's gotta be a way under Edit --> Keyboard Shortcuts - but I can't find it!
Thanks,

IMac 24" and adjusting brightness.

Hello. I have this fancy (and great) iMac 24". Only annoying thing is that when I try to adjust brightness, it just does not "adjust" brightness. Difference between "none" and "full" brightness is close to nothing. I have so far zap Prams, deleted prefs, turn green and shouted that I am Hulk - any ideas?
I know that there is Shade and other small apps to do this. But Brightness-control should efeect as...well... a brightness control.
Sooooo...any ideas how to get a working brightness control by keyboard?

Yeah, I have. And system preference panel.
When I press F1 or F2 to adjust brightness I have this normal response in display (picture). I dont know whats the right word for it but I mean the white brightness slash hovering on my iMacs desktop. You know, when You press volume controls there is a picture of speaker and when you press brightness there is a picture of rising sun.
Anyways, I get that. BUT THERE IS NO VISIBLE CHANGE IN BRIGHTNESS BETWEEN HIGHEST AND LOWEST.
Same thing via System preferences. Brightness slider has the same lack of adjustment.
Sooo, any ideas? Where could be the problem?

Adjusting brightness on BOOTCAMP

Hi
All along i was able to adjust the brightness and volume using F1,F2 etc when i was using windows 7 on macbook pro until recently. I was also unable to right click and scroll using the trackpad.
I downloaded input remapper to adjust the brightness and i just dragged it too fast and my whole screen became the dimmest! Which means I can't see a thing while running windows 7 now and what's more i can't adjust it back using the fn key! The mac system is all well, still able to adjust brightness and all. Is there anyway to adjust the brightness of bootcamp(windows 7) through the mac system?
Thanks!

I just found out a solution! Open your mac then look at your battery if you see a little plug cnected to the battery simply unplug it... If you're still a little confused watch a video on youtube. Remember you don't have to unscrew anything else once your mac is open. Hope this helps, don't be scared to do this if you're new to opening macs.

How to adjust brightness in book module

I created a book with 75 or so photos using Lightroom 5.3. Everything is ok and all done - but I forgot that my display is overbright so that I can see things clearly. On single images, I increase brightness and contrast in the print module before saving off a single file to print. I don't want to do this to all the 75 images one at a time. is there a way to adjust the brightness/contrast in the book module kind of in a batch?
If not, what does the print adjustment equal to in the develop module? For example, I have found through testing, that if I go with +67 brightness and +51 contrast in the print module, it compensates any photo that I have developed in the develop module with my overbright display.

How do you adjust the brightness on a Thunderbolt Display

How do you adjust the brightness of a Thunderbolt Display attached to an iMac ?

I had this peculiar ‘issue’ hooking up to my MacBook Retina when my Thunderbolt Display was delivered but Applecare - thanks Andrew - got me there. It seems daft!
The Thunderbolt Display Brightness slider IS there – you just have to know how to make it show up.
At initial set-up of the Thunderbolt Display [or if the Brightness slider is ever not visible in the System Preferences> Thunderbolt Display window], so long as the Thunderbolt [external] Display and the Macbook Display are ‘mirrored’ I can control the Thunderbolt [external] Display via my MacBook Retina Brightness keys [F1 & F2] – or by the Brightness slider that THEN appears in my System Preferences>Thunderbolt Display window. Once set up the Thunderbolt Display System Preferences Window continues to show the Brightness slider but I occasionally lose it if my MacBook has been disconnected from the Thunderbolt Display for some time – and I then have to start over.
So:-
Apple menu >
System Preferences>
Displays>
Click Arrangement [at the top]
Click Mirror Displays [at the lower left]
That then gives me-at-least a Brightness slider on the System Preferences> Thunderbolt Display window [as well as on the Built In Retina Display window] and I can then adjust them independently.
Oddly, having set this up just once the Brightness slider then remains on my Thurnderbolt Display and I can control it [and my MacBook Retina Display independently]. Occasionally I lose it again and have to start over.
Hope this works for others.

Program to automatically adjust brightness dependent on power source?

I just bought a MacBook Pro and would love to have my screen brightness adjust automatically based on whether or not the machine is plugged in. I find that the first thing I do when I plug it in or unplug it is adjust the brightness. I like the screen at full brightness when it is plugged in but on a lower setting when running on battery power.
You would think that the Energy System Preference would include these settings. Does anyone out there know of such a beast???
Thanks,
Frank

It's in the Energy Saver Preference - battery then
click options - there is a box.
I am aware of that setting: "Redcue the brightness of the built-in display when using this power source"
However, what I am looking for is something that will allow me to specify EXACTLY how bright I want the display to be when it is plugged in and how bright I want it to be when it is not plugged in. The checkbox provided in the Energy Saver preference does not give me any control. How much is it reducing it? What if I had already manually set it low? Will it reduce it further? The checkbox is basically useless.
Thanks anyway,
Frank
