Mac Pro :: Brightness Control And Dual 24" LED Displays?
Apr 26, 2009
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.
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?
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 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.
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've mini connected to 2 dell 24" LCD displays thru Y splitter (DVI to DVI/VGA). 1st display connects with DVI and the second with VGA.
Vista (bootcamp) can see both displays and it can extend the desktop to the 2nd display.
Since windows on bootcamp can use 2 monitors and OSX can't I would assume that this functionality has been disabled by apple in OSX or display driver. I know that the windows VGA driver provided by apple (bootcamp) has the dual display disabled.
Here is the question: Where would i have to look in OSX to enable 2nd display?
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 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've been a mac guy since 1990 and for the last five years have settled into a nice PowerMac G5 with the dual 2.0 processors with the 20" Apple Cinema Display.
I did search on this but couldn't find anything specific, but I am considering adding a second 23" Apple Cinema Display to my set-up for a dual monitor workstation.
I have the ATI Radeon 9600 video card with two DVI ports. I have my 20" plugged in to port 1 and it's running at 1680x1050 resolution (the highest). When I add the second monitor, will BOTH monitors be able to run at their highest resolutions? Or do I need to add another video card?
I had heard rumor that resolutions are a trade-off: if your card is split between two monitors, then the resolution splits, true?
If I can run both at the highest res, then I'll pull the trigger and get the extra monitor. I'm assuming there's someone here who has done the exact same thing?
I currently have a 17" G4 PowerBook which I LOVE. The only problem is that I'm a graphic designer and need more screen real estate. I've been considering purchasing a 30" ACD and waited for MacWorld hoping that an upgraded version with higher specs would be announced.
Sadly, it wasn't and I don't want to keep waiting indefinitely for Apple to update their displays. I've heard some good reports about HP's new 24" monitor (http://h10010.www1.hp.com/wwpc/ca/en...-12401740.html) and on the surface, the specs seem to be a lot higher than Apple's 23" monitor and the price is cheaper.
Currently, I can purchase the HP for $999 CDN while the 23 ACD is $1,099. Also the HP comes with a three-year on-site warranty while the ACD only has a 1-year warranty. I'm considering purchasing 2 of HP displays, which would give me acres of screen space. Soooooo . . .
A couple of questions:
1. Is my 1.67 GHz, G4 PowerBook capable of driving 2 x 24" monitors simultaneously?
2. Does anyone have any experience with the HP monitors and if so, would you recommend them?
As a loyal Mac user for the last 12 years, it irks me to even consider purchasing a product from HP. However, I just cant justify spending more money for a product with lower specification.
so I love Macs but they're frustrating the hell out of me. I wanted to run dual 20" displays (portrait) and one 30" displays using a Mac Mini and a Macbook Pro. I know the new Mini should do it, but I've heard bad things about Apple's Dual Link DVI adapter. Also, I don't think there's a way for a Macbook Pro to drive a 30" Display and a 20." Am I missing something? What should I do?I'd much rather buy a Mac Mini than the Mac Pro which is way too powerful.
On my left I have a new HP 2311 23" monitor (maximum dpi 1600x900). On my right I have an old 23" Apple HD Cinema Display (max resolution 1920x1200). Both have a 16:9 aspect ratio. I just added the HP about a month ago, and this is the first I've had dual displays....so I'm still learning. I've noticed the following: If the cursor is on my Cinema Display and I move it left toward the HP, at about the top 1/4 of the screen the cursor won't cross over...it comes to the edge of the screen and stops. I have to move the cursor more toward the middle to cross over. When I move the cursor down toward the middle of the Cinema Display, it crosses over but appears a the top of the HP.
A similar thing happens moving from the HP to the Cinema Display, except at the bottom of the screen. The cursor won't cross for about the bottom 1/4 of the HP, and when I move the cursor up so it will cross, it appears at the bottom of the Cinema Display. It's almost like these screens are out of alignment....the HP sitting a few inches higher than the Cinema Display. My eyes aren't what they used to be, so the HP is set to 1344x756 and the Cinema Display is set to 1344x756 to make everything larger. However, I tried many variations of the resolution on both screens to see if that changed anything.....it didn't.

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.
i have an imac intel core duo late 2006 model... with a 20 inch display... it has 128mb vram and i'd like to add another display. i run my mac with the highest resolution of 1680 x1050 and i'd like to keep this resolution and add another display maybe another 20" screen. has anyone done this? and what are the performance results... will there be any lag or problems?
Is it possible to get dual displays with these on the laptops? How would this be done? I've been using dual displays at work and have been planning on buying one of these.
I have an old iMac G3 in my room running Mac OS 10.3 Panther. Just recently, I hooked up a VGA CRT monitor in an attempt to run dual displays. However, it seems that all the machine or OS is capable of is running in mirrored mode.
I am soon going to be buying a Macbook Pro to replace my hackintosh and return my hackintosh to a well spec'd windows PC with dual monitors (one of which will also be connected to the MBP.
Which monitor should I go for?
I have been using a Samsung SM2333sw and love it. It is a TN panel, but it is perfectly usable for my needs, however, the bezel it quite thick so doesn't work well as a dual display option.
The only key features is that the monitor needs to be 23/24", have 2 inputs, and have a fairly thin bezel.
I need to be able to get both screens for around �250 each.
I wonder if anyone has a setup with two 24 inch cinema displays that have speakers integrated into them...
How do the speakers work? Do you run a USB cable to each monitor so you have both sets of speakers working at the same time? Can you configure the monitor on the left to just play audio for the left channel and the monitor on the right to play just audio for the right channel?
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 an Early 2009 Mac Mini with Mini DVI and Mini DisplayPort. And I have two 1080p HDTVs. The Mac Mini is capable of dual display, and I've gotten it to work before, so the issue is not the TV or Mac. And I have tried both Mirroring and No Mirroring.
I got a Mini DisplayPort to HDMI Adapter (#5311) and a Mini-DVI to HDMI Adapter (#4852) both from MonoPrice. And for some reason I can't get the Mac Mini to dual display, it's only one or the other.
Before I had a Mini Displayport Male and USB Male AUDIO to HDMI Female Converting Adapter (#5969) and I got video on both HDTVs, but not audio at the same time b/c one was USB and one was TOSLINK.
I'm not sure why I can't get video on both monitors. Any help?
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.
So I installed Vista 64 bit on my Macbook Pro (Santa Rosa), I installed most of the drivers I can find, but I cant get the screen brightness buttons to work (F1 and F2)
