Hardware :: How To Control Brightness In Windows On LED ACD
May 19, 2009
so I'm planning on buying and LED Cinema Display to go with my Mac Pro. I have a few issues before I pull the trigger...
Currently, I'm using a 23 inch Acrylic Cinema Display and have found that there is no way to adjust overall monitor brightness. Even using the ATi control panel (my Mac Pro has an Apple branded ATi 4870), there are no true brightness controls either on the software side in Windows (I haven't found a way to change brightness in Windows like I do in System Preferences in OSX) or on the hardware side (no buttons on the monitor itself).
Basically, as soon as I use bootcamp to reset into Windows, I notice that the screen immediately goes to the lowest brightness (even though I was running the max in OSX before switching) settings as soon as I go into the desktop. Playing games like this is irritating.
I know the LED Cinema Display also has no brightness buttons on it, so will I still be SOL?

I don't know if anyone posted this issue before. I can not control screen Brightness on my MBP 13'. I tried my F1 and F2 key and the Nvidia Control Panel, either of them is working. I installed all the drivers from the CD and it can actually show the icon in the center(bottom) of the screen when I hit the F1 or F2 Key. However, the brightness adjust does not work,the screen stay the same.

I bought this c2d macbook pro 15'' in early 2007. Today I installed windows 7 on it (bootcamp 2.1). Everything worked perfect except the screen brightness control. The strongest level is very bright (same as the one in Mac), but the second level is very dim. I remember having this problem back in 2007 when I installed winxp on my mac. Looks like the problem still exists. Anyone here knows how to fix it?

I am using a Samsung monitor so therefore cannot control th screen brightness with the F1 F2 keys.
I tried Shades but it messes with the colour making it look a little washed out and not good.
Are there any others I could try ?

It seems that the control keys for brightness (default F1 & F2 keys) and volume (default F3, F4 and F5 keys) have moved to another key combination. Don't ask me what I've done . I already tried Fn, but that did not help.
Does any know how to rearrange the keys to the default keys?

I have setup the 23i cinema display with mac pro. I have connected the USB and firewire cable to mac pro.. and keyboard is attached to back of the display. For some reason I cannot seem to adjust the brightness of the display from the keyboard (though I can do it from the side of the monitor). Neither can I see the brightness slider bar in the display settings. Also while the display is the the power led in the front blinks 3 times, then there is a little pause, and blinks 3 times again. How to fix this brightness control issue with the display. I have reseted PRAM and NVRAM... still nothing has changed. Also note I do not have and options tab for some reason.... (I have tried to plug the display's usb into the back 3 usb of the Macpro... still nothing)

I've got a 2009 Mac Pro with both a 4870 and a GT120, and I'm experiencing a strange bug with the brightness controls. The keyboard buttons only control one panel, and *both* of the sliders in the displays system preferences panels only control that same display. There is way to control the brightness of the other panel.
Here's a short clip of the problem:

When my laptop is connected to my Apple Keyboard, I can control the brightness with the F1 and F2 keys on my external Apple Keyboard. However, when I connect an external monitor to my MacBook Pro, the F1 and F2 keys no longer work.
Is there a way to control the brightness of my laptop's screen (NOT the external monitor) with my external Apple Keyboard even when an external monitor is plugged into my MacBook Pro?
I have the late 2008 uMBP.

The Apple BT keyboard doesn't seem to support adjusting the MBP's keyboard brightness with F5 and F6.

The reason I am asking is that I am using a Spyder colorimeter to calibrate my monitor and it is asking me which controls exist on the display:
-brightness
-contrast
-backlight
My thinking is that F1 and F2 control the backlight level and not the "brightness" level, if you get what I mean.

I have a 24inch LCD ACD display connected to my Mac Pro. This display all used to work OK, but now, read on. I had to send this 24inch LCD ACD display away to have the panel replaced. Since it has returned when I look in About This Mac/Displays it shows that I have an iMac connected as the display and now the brightness cannot be controlled. If the 24inch LED ACD is connected to my Macbook it all works as it should

I cannot control my screen brightness using the F5 and F8 keys. The only way I can adjust it is through System Preferences. I tried just F5 fn F5, Control F5, Option F5 and Command F5 and non work.

Recently, my newer (last year) iMac probably running 10.5 started speaking and wont shut up... there is no obvious way to turn it off. I usually figure problems out myself but there are no system preferences that effect it. I even changed the voice in preferences as a test and it is still the same guy reading everything clicked in all applications except when I am in system preferences so far. Usually when I run into a dead end like this there is some mystery key command that works... anyone know?I also noticed that some of the top line (f) keys are not doing what they are supposed to any longer as well... volume up opens the window for expose & spaces it looks like and does not control the volume monitor brightness controls are not working either... I went to the key and mouse preferences and set the key strokes to default and still the same.

I have a macpro with OSX on one drive and windows 7 on a partition of another drive. Both systems work fine and I boot into windows by holding the option key down. What is odd is if I go to the system preferences startup disk my windows install does not show up. I did move my windows partition a while ago to a new drive. I used bootcamp to create the partition and winclone to move the data. It's not a big deal not having the option in the preference pain but would be nice. If I am in windows and go to the bootcamp control panel both OS X and Windows are there.

I usually have my screen brightness set to a few ticks above the lowest, but when my screen shuts off (after 3 mins or whatever I have it set to in the control panel) and gets turned on again, the brightness is set to max. If I then drop the brightness by one tick, it drops to where it was set before. It doesn't do this when I close the lid but it does go to full brightness when I restart the computer and as I enter the windows desktop it goes back to what it was set at.

The brightness goes up when you plug in your MBA, but then over time it just goes up and up. I honestly like my brightness pretty low (rarely more than half, typically at 3-5 notches), but it just keeps on going up and up. I almost never set it above half, but multiple times a day, I notice that it looks pretty high and it's at like 3/4 so I put it it down to about 1/3, but after a while, it's just up again.
Anyone else notice this? What is it, why does it do this? How can I fix it? I don't mind not having auto-brightness (even though I loved it), as long as my screen doesn't keep going up.

I have recently put windows 7 professional on my aluminum macbook, installed all the drivers, and so forth. I hook up my macbook up to an external monitor, and use a logitech dinovo keyboard for a mac. However, when I am in windows 7, the function keys do not adjust volume, brightness, and any other of the functions.

Is there any way I can switch the functions of these two? I've searched and googled and checked microsoft and to no avail. But I want to copy and paste or undo and things and I press command and the start menu pops up. Not only do I not want that to happen but I'd like the command button to function as the control button.

I've been using Lubbo's Fan Control to keep my fans high while playing games with Boot Camp. I've noticed an issue, though. The fans run what I set them to well for about 1 minute, then they die down for about half a minute, then they start working again. What's happening? I've tried other tools and they all do the same thing.

Is it possible to switch the control key to the command key in Windows? I am so used the to CMD shortcuts, and hate having to move my finger to CTRLI downloaded a program to edit the registry, but it didn't change the command key, just the control key. So I had two keys that were assigned to the left command button. I cannot remember the name of the program for the life of me.
