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.
My wife has an iMac (I don't know any other way to identify it e.g. model number), and she has this 3rd party calibration software that I'm trying to use. I am not used to a Mac, and I cannot find the display settings for the monitor. There are no buttons on the monitor, and when I go to preferences, I can only find the brightness control. I've googled this and cannot find a clear, simple answer. I have used every version of Windows (currently on 8.1 on my PC) and it's easy for me on that platform. I suppose it's just that I don't really know how to navigate Mac OS.

iMac, Mac OS X (10.6.8)
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)
View 1 Replies View RelatedI 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
So I have an AVI file that won't even load in quicktime, but it plays fine in VLC and MPlayer. As far as I can tell neither of these programs let you adjust the color, contrast or brightness of the file. Does anyone know of a program that will allow me to do this?
View 1 Replies View RelatedA month or so ago, the backlight randomly went out on our MacBook. If you look very closely you can see the screen, but it's like you've got the brightness on its lowest setting. The backlight comes on as normal when you turn on the computer, or wake it from sleep, but goes out after about 2 minutes. Other than not being able to see what's going on, the computer works fine. I took it to the Apple Store, who said they'd have to replace something at a cost of ?75, which was fine. Just over a week later, they called and said that hadn't worked, and that it was actually the logic board that needed replacing, at a cost of ?385, more than the value of the computer. We decided it wasn't worth it.
Yesterday however, I took it to a friends and connected it to his monitor, and even though the screen was dark on the MacBook, it came up fine on the monitor. To me, it seems strange that it's a logic board issue when it works fine with an external display.
My keyboard backlight buttons dont work. The keyboard backlighting works when I'm in low light conditions, but I can't control them with the buttons. When I press them it comes up with this:
View 3 Replies View RelatedI looked all over the system preferences pane, and although I can change the setting for the screen itself, I cannot over-ride the light sensor controlling when I can use the backlit keyboard.
There are some cases where I want the backlighting on, but when I press the button to turn it on it won't let me because the sensor is picking up too much ambient lighting.
My display looks like the contrats is on high, but I don't know how to change it. I've gone through the color calibrations and nothing seems to help.

Does any know how to rearrange the keys to the default keys?
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 was plugging along on the internet when I decided to try the spoken commands for the first time. When I opened System Preferences and clicked on the microphone, at that instant my screen flickered and changed in both quality and what appears to be contrast and tint. I tried in vain to correct this by way of the controls for the Display in Sys. Prefs. but to no avail. I would like to know if I have a video problem or a memory problem.

View 5 Replies View Relatedso 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 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 ?
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.
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?

View 3 Replies View RelatedRecently, after about 5 minutes of use (not sitting idle), my MacBook's screen will go very dim. I hit the buttons on the keyboard to take the brightness all the way up, but it doesn't get much brighter and there's only one thing that I can do to make the screen go brighter: I go into System Preferences and click Display. The second I click that, the brightness returns without me doing anything in the Display section, so after Display comes up, I just close it out and the screen brightness is fine for a while. It seems to do this after the lid has been closed for a while and then starts dimming again after opening the lid and using it for about 5 minutes. Is there a way to fix the auto-dim mode without disabling it? MacBook (white) is running Leopard 10.5.8 with all the latest updates.

View 9 Replies View RelatedRecently, 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.
