Does anyone have two 24" LED Cinema Displays on their Mac Pro?

I'm wondering if there are any other Mac Pro users out there with two 24" LED Cinema Displays? If so, are you able to adjust the brightness of both displays? For me, no matter which brightness slider I adjust in System Preferences, only the brightness of one of the displays is adjusted.
I originally created a thread last September:

If you have this problem too, please report it to <http://bugreporter.apple.com/>. My original Radar bug was #7222745, and it was found to be a duplicate of #6828443. Based on the IDs, I'd say this has been a known issue for at least a year.
Thanks,

I am using logitech G19 mouse and Naga Razer Epic, my current suspect that is their official driver which make my OS X 64bit kernl go nut. Does Logitech Control Center work for later version of their products such as G19?
If I plggued in the G19 without installing their official gamepanel software, The heyboard still work, volume control slider works like a charm. I just get no advantages from the LCD screen (kind of pointless).
If I install the razer mac driver, I keep seeing error log in console for the kzcorengineand razercorenginer process.
Idid clean install of Mac OS X and have not experienced freeze except once when I was plugging in my 500gb transcend external drive. This Ext. Drive require two usb slot for power and transfer data.
I am not sure if the freeze was coincidental or related to the transcend external drive I used. I did a directory permission repair and a repair to the mac drive, how things seems to stabilised.
However I want to take my test further to install office 2011 to see if it cause those random unpredictable freeze again.
Sigh, I paid $200 for such a good keyboard, but they have bad apple support. I dont like the apply ketyboard and magic mouse. It's immpossible to touch type on and even harder to play any game at all.
Wayne, when you use your logitech product, do you install the product specific driver for each product plus LCC? or you just install LCC.
Thank you

Two 24" LED Cinema Displays from 2009 Mac Mini?

I have been using two 24 inch Samsung's with a Mac mini for about 6 months and it's been great until one of the monitors failed me last week. After some research I purchased a new 24" LED ACD and it's a beautiful monitor that blows away my other 24" Samsung. I'm thinking about getting another 24" LED ACD and my question is: Has anyone connected 2 24" LED ACD's to a Mac mini using: http://www.atlona.com/Atlona-DVI-to-Mini-DisplayPort-Converter-p-17859.html
My plan is to use the mini display port to connect one ACD and use the Atlona Converter to connect the other ACD through the mini DVI port on the Mac Mini. I have the Atlona converter ordered and it will be here early next week and I'll report back on the results unless someone else has already done this and knows it works.

Just one further question, though - doesn't that mean I lose out on other uses for the Mini's only Thunderbolt port?
No, because Thunderbolt can be daisy chained. Just make sure that whatever Thunderbold Drive Enclosure you get, has dual Thunderbolt ports so that you can chain your second monitor to it.
see > Displays: Mini DisplayPort display must be last in a Thunderbolt chain
Also, can I ask why you suggest putting the 20" on HDMI? If it came to running a single monitor + Thunderbolt RAID setup, I'd like to have the 23" on the HDMI.
Mostly because the Thunderbolt/Mini DisplayPort supports higher resolutions than the HDMI port.
HDMI to DVI only supports 1920x1200
Thunderbolt port supports 2560x1600
Would that be problematic?
Not as long as the 23" monitors native resolution is 1920x1200 or less.

Two 24" LED Cinema display and getting audio from both

I have two 24" LED Cinema displays connected to a MP. Is there a way to get the audio to play through the speakers on both displays at the same time? I can easily switch the USB audio to either display, but I cannot figure out how to play audio through both at the same time. Thank you for the help,

You can hijack the audio from any application, or the system audio, with Audio Hijack Pro
<http://www.rogueamoeba.com/audiohijackpro/>
You can then use its Auxiliary Device Output effect to send the audio to multiple devices.

Controlling brightness on two 24" LED Cinema Displays

I have an 8-core Mac Pro from this summer with two NVIDIA GeForce GT 120 cards and two 24" LED Cinema Displays. I'm running Snow Leopard 10.6.1, and when I try to adjust the brightness, the slider on both panels controls only one monitor. I therefore can't adjust the brightness of one of my displays. Has anyone found this?

I filed a bug report at bugreporter.apple.com, and received a pretty quick reply:
This is a follow up to Bug ID# 7222745. After further investigation it has been determined that this is a known issue, which is currently being investigated by engineering. This issue has been filed in our bug database under the original Bug ID# 6828443.

Looks like I'm S.O.L. until they fix this!

Does anyone use a LaCie external hard drive with their Mac using imovie '09? I have some questions.

Does anyone use a LaCie external hard drive with their Mac using imovie '09? I have some questions.

Are you actually having a problem with the new Lacie drive, or are you just asking is the Lacie drive somehow different from your old G-Drive?
From a connection standpoint, most Lacie desktop drives have both USB and FireWire connections, just like the G-Drives do. You would connect and use it the same as a G-Drive.
Regarding capturing to the external HD, if you are using a camcorder that has FireWire (iLink) connection, it is not advisable to have an external FireWire HD connected to your Mac at the same time as your camcorder; there are often communication conflicts between the camcorder and the hard drive if they are connected at the same time. The conflicts usually appear as either dropped frames or a complete freeze. This is more common with Canon miniDV camcorders but I have also seen this behavior with Sony miniDV camcorders. (The problem is the camcorder's FW implementation, not the hard drive.) The workaround is to capture to your Mac's internal HD and later copy the captured video to your external HD.

telling me to buy a new router is NOT a solution.
And why not? Apple is selling these things like BigMacs. They can't make enough of them. You've been suffering since May because you refuse to get a decent router.
Can you imagine if a company that makes a refrigerator told me that I needed to upgrade my electrical system to rectify a problem with their device? What kind of response IS that?!?!
What if the problem with their device is that it requires a new-fangled "grounded" outlet and your circa 1890 house doesn't have grounded outlets. Would you refuse to purchase a $ 25 adapter on principle?

Problem w/ two 27" LED Cinema Displays on ATI 5770 MacPro

Attempting to connect a second display to a mid 2010 Mac Pro. There are two mini-ports + a DVI on the 5770 card. Currently I have a single 27" LED connected using one of the mini ports. The computer isn't recognizing the second monitor in the other mini port. I used to have an older 24" LCD Cinema display running successfully, using the DVI port on card with a powered adapter. That configuration isn't doable with a newer 27" given the output from it (not the older style video cabling, but rather the mini display port. Would appreciate any suggestions on how to get the two 27" monitors running together.

Hey turbostar, finally a chance to get back to you, sorry about the delay.
I had already tried both ports with no success on the second monitor, but when I moved the primary monitor to the second port and it worked... it it got me to thinking maybe the power outlet was bad if not the monitor itself. Indeed that was the issue. The second monitor was plugged into a power strip in which one of the six outlets on it was not working. Replaced the surge power strip with a new one and all is good.
Thank you for your time and help.

Why does my 27 inch LED cinema display freeze my Macbook Pro when connecting?

Hi,
I've had a 27 inch cinema display for about 2 years now and love it.
However, a good 50-70% of the time whenever I attach my MacBook Pro, currently 15 inch late 2011, rather than waking up the MBP, it just freezes the computer. The same thing used to happen with my 13 inch MBP.
Any ideas why that is?
thanks,
TT

I finally decided to just take my MBP down to the Apple store and see what would happen if I connected it to one of their new ACDs. At 1st, the guy at the Genius Bar told me that my MBP only supported 1280x800 as a maximum resolution. I told him that was for my MBP screen, and not an external monitor. Finally I convinced him to let me connect my MBP to one of their monitors. Low and behold, looking at the Display settings pane I saw some addtional resolutions, including 2560x1600!
So, now I have confirmed that my MBP can drive an external monitor to a resolution of 2560x1600, using just the single mini displayport connection. I just have to figure out what's wrong with my ACD. Suspecting that my older ACD might not support this higher resolution, I did finally discover that my model only supports a maximum resolution of 1920x1600.
Sorry for all the confusion...

HT2844 When I plug my LED cinema display into my macbook Pro, the video switches automatically but the audio still plays via the macbook speakers by default. Is there any way to make the audio default to the display audio when plugged in?

Hi,
Pretty much as the tital says really. I'm fed up of having to manually select my audio output every time I plug my macbook pro into me LED display. Can I make it default the audio to the display when plugged in?

yeah- I think so, AlexGrady. see if your machine supports hdmi audio out, it should say under "about this mac"
then buy the correct adapter to your LED display. I think you also have to enable audio out via HDMI, and the adapter has to support HDMI audio passthrough
sorry, that's all I have for now

Using a 30" Cinema Display with new Mac Pro

Hello Everyone:
I just purchased, and waiting to arrive a new 2014 8 core Mac Pro which is an upgrade to my 2009 quad core Mac Pro. I currently use a 30 inch Apple Cinema display which has the DVI connection. I was thinking that I would use a DVI to HDMI adapter and plug the 30" into the HDMI port on the new Mac Pro. I have since heard that people have been having issues with this older monitor getting it to work properly with the new mac pro. some have suggested buy the $99 mini display port to DVI adapter and using that, but I don't believe there is a mini display port on the new mac pro.
I have considered buying a new thunderbolt display because I am assuming that it will have a much better image quality than the older 30 in display but I hate the fact that it's a 27" and I would be giving up the 3" in size. I do a lot of video and audio recording editing and love the extra screen real-estate. Can anyone confirm a couple of things for me?
1. Will the 30 inch display work with a new mac pro and can I use the DVI to HDMI adapter?
2. Does the new Thunderbolt display have a much better image quality than the 30 in display and because its newer, will look that much better with the mach pro?
Thank you in advance.

1. Will the 30 inch display work with a new Mac Pro?
Yes.
Can I use the DVI to HDMI adapter?
Not if you want full resolution. You need a Mini DisplayPort to dual-link DVI adapter
<http://store.apple.com/us/product/MB571Z/A/mini-displayport-to-dual-link-dvi-ada pter>
It plugs into a Thunderbolt port (and USB port) on the computer.
2. Does the new Thunderbolt display have a much better image quality than the 30 in display and because its newer, will look that much better with the Mac Pro?
No, it has more pixels (in the vertical direction), but they are spaced a bit more apart, so you don't want to be as close to the display.

Using 2005 30" Cinema display with new mac pro

I will order a new MacPro to replace my Mac Pro 1.1 immediately upon release. I also have a 30" Cinema Display version 2005. It's interface with the existing Mac Pro is three cable hookup: DVI, USB and Firewire 400. By connecting the Cinema display using a bunch of adaptors, can I make the display work with the new MacPro until a good 4K display is out there? Alternatively, I'll have to buy a new display from current technology or the few 4k's available today.
Thanks for your help.

yes, use a Mini DisplayPort to Dual-Link DVI adapter plugged into the ThunderBolt port. The HDMI port has limited resolutions, not including 1560 by 1600 best for 30" cinema display.

How do you connect two 27" LED Cinema Displays together?

I currently have one screen connected to my MacBook Pro 2010. How do I connect the second screen if I only have one Thunderbolt port?

I Think they can be daisy chained.check your manual for more info to see if your Mac supports this

Does anyone have problems installing Adobe Flash Player on their iMac?

I download the proper Version of Adobe Flash Player. I double click and it says it was installed. But it really isn't. I also have uninstalled and reinstalled it but no go. Can anyone help me?

You can check here: http://www.adobe.com/products/flash/about/ to see which version you should install for your Mac and OS.
You should first uninstall any previous version of Flash Player, using the uninstaller from here (make sure you use the correct one!):
http://kb2.adobe.com/cps/909/cpsid_90906.html
and also that you follow the instructions closely, such as closing ALL applications first before installing. You must also carry out a permission repair after installing anything from Adobe.

Does anyone have an enzotech ultra-x hsf on their p6n sli plat?

I'm looking for a replacment hsf for my c2d and I tried a thermaltake tmg-i1 but the legs refused to lock into the holes so I'm rmaing it back. I've been looking at the tec (peltier) coolers and came across a chilltec unit. I pondered it for a little while but then decided to go with the enzotech ultra-x unit with the little alpha sink on the cpu pad. You can see it here http://www.enzotechnology.com/cpu.htm. Do any of you guys have this unit mounted on your p6n? I saw a review of it mounted on an asus striker with the heat pipes all around the cpu socket so it will clear the msi pipe with no problem.
