LED Cinema Display issues with audio and App Switching

The audio on my Cinema Display fails after about 20 minutes, unable to diagnose other than Mavericks.
When swithing between apps (seems like Safari more than anything else) I experience a 5 second freeze every 4th or 5th switch using external Apple Keyboard.
Alt-Tab or mouse click in dock makes the same the happen with Apple Keyboard
I do have an external Logitech Mouse but have treid all the other things in the other thread to fix that and it still happens with the mouse disconnected at start.
I don't have another external mouse to test.
Defeating the point of my external display, search through here isn't yielding much info...

I removed an older USB extensions cable and it reduced the frequency of it happening but it still happens.

Difference between a Apple LED Cinema Display (27" flat panel) and a Apple Thunderbolt Display (27-inch)?

May i know the difference between a Apple LED Cinema Display (27" flat panel) and a Apple Thunderbolt Display (27-inch)? both products look the same to me, even the prices are the same, but the name of the product is different. Its so confusing! I want to purchase a secondary display for my 21" iMac, but idk the difference between the two.
furthermore, another question i have is, is 27" the largest display i can get? is there larger ones (just the screen, not the computer)?
please help, thanks!

One has thunderbolt capabilities, the other doesn't.

No you can get a larger one. Maybe not an Apple one, but certainly another brand.

Will my 27inch LED cinema display work with the 2014 MacPro?

I have two 27 inch LED cinema displays I bought in 2010 I think. I want to know if I can use both displays with the new cylindrical MacPro? My displays have mini display port connection and are non thunderbolt. I know that I cant daisy chain the monitors because they are NOT thunderbolt, but will I be able to connect both to the new MacPro's coming this December?

Thanks TurboStar for your excellent comments and suggestions. I have pre-ordered that Apple 27" LED Display now off Amazon.co.uk... it will be in stock on the 21st March.... and I look forward now with anticipation to getting my hands on it and more importantly my eyes... now that I have read your resounding approval of the 27" compared to my tired and jaded 30".
Interesting your comments about the new MacPro also... I think I went OTT when I bought my last 12 Core MacPro (32GB RAM + 512GB SSD)..... it cost me in total €8,800 ($12,200) which was mad money.... it's doing a great job.... but I don't work with video or video games, just Quark, Illustrator and Photoshop... so not sure if the 8 Core or less would have done the job just as good... I just wanted the best with what I thought was the most horsepower so I could take on any task. I will wait and review more with the New MacPro.... maybe the 6 Core is the way to go... and pump up the SSD and RAM....
Thanks again.
Regards,
Anthony
PS. Have a grrreat Paddys Weekend!!

Apple 27'' Cinema display issue with nvidia quadro 1800 - Win 7 64bit

Hello,
I'm trying to help out a buddy of mine with his cinema monitor.
He has a Windows 7 x64 machine, with a Nvidia Quadro 1800 - monitor hooked in via DVI port.
Basically when you boot the PC up with the Apple monitor, the monitor turns on and backlit but no display, no options for BIOS or anything like that, just lit up and black screen.
I can boot up the PC with a Dell monitor and it boots up fine - and if I take the DVI out of the Dell monitor and plug it in to the Apple monitor while the machine is up and running, the Apple monitor comes on and works without issue - however, if you were to reboot it, or if it goes to sleep - I lose the Apple monitor, and have to start the process over.
The Windows machine recognizes the Apple monitor, it displays as Cinema monitor - all the video card drivers are up to date - also had the same issue with a previous video card (I swapped the video cards out thinking initally it was a bad video card)
What am I missing?
Thanks!

HDCP display issue with Yosemite and Macbook air

Hi - Sorry if the question has been asked before and answered.
I have an issue where since I have upgraded to Yosemite, I cannot play any of the movies I bought prior to upgrading and I can even play trailer from the iTunes store...
Any ideas?
Thanks

Too bad this didn't help.
HDCP errors can also occur when your display settings are incorrect and when you have non-original / non-Apple display software installed. Think a special driver to support a specific type of external display, or a remote viewer application like TeamViewer or AirParrot.
If you're having the HDCP error with an external display, disconnect it and test with the MacBook Air's own display.
If the issue persists on the MacBook Air's own display:
To restore your display settings to factory default: do a PRAM reset:
http://support.apple.com/kb/PH14222?viewlocale=en_US
Shut down your Mac.
Locate the following keys on the keyboard: Option, Command (⌘), P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on your Mac.
Immediately press and hold the Option-Command-P-R keys. You must press this key combination before the gray screen appears.
Continue holding the keys down until your Mac restarts, and you hear the startup sound for the second time.
Release the keys.
If you have special software installed, it would be best to try to boot the computer to safe mode:
http://support.apple.com/kb/PH18760
Choose Apple menu > Shut Down.
After your Mac shuts down, wait 10 seconds, then press the power button.
Immediately after you hear the startup tone, hold down the Shift key.
You should press the Shift key as soon as possible after you hear the startup tone, but not before.
Release the Shift key when you see the gray Apple logo and progress indicator.
If that doesn't solve it, peruse your Applications folder in the Finder and see if you can delete unwanted video / viewing-related applications.

Logic issue with audio and instrm tracks!

Hi!
Iam old Cubase user And i didnt see THAT on Cubase
When i cut a part of audo region or close the end by draging bottom corner of region,it play anyway on empty space
Any ideas?

or.. did you mean that after you've cut audio, and you hit play, you still hear something playing even when visually, the timeline bar shows that there should be silence at that point? if so, this could be something to do with plug in delay compensation.. the visual representation of your arrange window is slightly out of sync with what you are hearing. I think I've seen this happen before in logic under certain conditions, but I'm not sure exactly when. it could be something to do with PDC as I mentioned, so look into that.

30 inch cinema display compatibility with gefen dl kvm switch

I have a power mac dual 2.7 and 3.4 intel pc with ati radeon and gefen dl switch. The monitor work well on the apple but the pc loads up on the window xp opening screen but got black when it should go to the desktop. It seems that the monitor doesn't work with the video card. are there cards that are more compatible with monitor and or the gefen dl switch
PowerMacG5 2.7 Mac OS X (10.4.9)

It sounds like the driver still isn't right. No, hdcp has nothing to do with it. Have you thought about moving your question to a PC forum somewhere? You might find people with more WIndows expertise compared to here. Good luck.

Canvas display issue with stills and cross fades

When viewing a collection of JPEG stills with cross fades, the images appear like they are "settling in" the canvas window (almost as if they expand a bit and then 'retreat back' to the space the window has). When removing the transitions I don't have the issue. Issue also appears when do more complex builds. No difference whether stills are exact 720x480 or much bigger. I rendered a portion of my sequence out to QuickTime and via Compressor and it shows normal - so my only issue is that my preview before render is not reliable (for the stills portion). Also tried to swith off external video options etc. and changing size of canvas window with no result. Suggestions? (using FCP 5.0.4 and latest QuickTime)

I rendered a portion of my
sequence out to QuickTime and via Compressor and it

before render is not reliable
The preview of unrendered material is never reliable and isn't meant to be. It just gives you a basic idea what's there. Render the transitions and you should see them as they are meant to be seen.

Is there a way to turn off a 24" LED Cinema Display without unplugging it?

I recently bought a 24" LED Cinema Display to use with my Macbook Air 13". However, it doesn't seem to have an "off" button. When I close the MacBook Air, the display is active - so it can be used with peripheries - but I'm not sure how to turn it off safely.
If there is no way to turn it off, which I suspect is the case, is it best to disconnect from the computer or from power to turn it off each day?
Thanks for any suggestions.

Hey ASMNYC,
While the Apple 24" LED Cinema Display does not have an off switch as such, and can not really be turned off short of disconnecting from power, it is possible to put the display into a low power consumption mode - display sleep. See this article for more information about Energy Saver modes -
About Energy Saver sleep and idle modes in Mac OS X - Apple Support
Thanks for using Apple Support Communities.
Be well,

Photoshop issues with MBR and LED Cinema Display

Hi,
I have my MBR 15" connected to a 24" LED Cinema Display. In Photoshop, when dragging windows to the secondary display (the Cinema Display) they turn immediately black. If I drag them back to the main monitor (the MBR) they will show up normally.
Now, if I change the main and secondary displays (1st-CD; 2nd-MBR), this will happen again on the secondary.
I really need to have both displays working with Photoshop. Does anyone know a workaround to this?
Thanks in advance,
Jorge

Sorry, forgot about that. It's Photoshop CS6, already updated to be Retina capable (version 13.0.2).
I'm going to check for further updates.

27 LED Cinema Display Audio and Brightness when powering MacBook Pro

When my 27 LED Cinema Display is powering my (or another) 2009 13" MacBook Pro, I have experienced three issues:
1. The dropped audio problem other users have mentioned. Shutdown, then disconnect power/usb/displayport, then wait ~15s, then reconnect and reboot temporarily fixes the problem.
2. I also have the sluggish keyboard behavior when adjusting the volume that others have mentioned.
3. I have experienced shifts in display brightness which are obvious when the display is dimmed. I have disabled the ambient light sensor as well as any interfering power management or energy saver settings. Opening apps, scrolling and other normal activities seem to aggravate this behavior.
This last strange behavior inspired me to try using a power adapter for the MacBook Pro instead of display's laptop power connector. *Doing so seems to have resolved all three issues.*
It seems that this may indicate an underlying problem with the display's power supply. Can anyone confirm?

I am having the same issues & with a 1 day old display. I am using a 15" MBP. The screen is killing me when it dims down when no lights are on. I didn't notice the issue when the screen is brighter with the lights on. Anyone know if this is a hardware or software issue? I'd like to utilize the ambient light sensor but not if its going to make my screen flicker when it is dim....
(1) I have never had any deaths associated with my screen, but on rare occasions my display's brightness will flicker when I manually adjust the brightness. The fix I have found for this is to increase the brightness one more setting or decrease it one more setting. Changing the screen from full dim to full bright and then setting the brightness I want sometimes helps, too.

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.

Problem with Snow Leopard and LED Cinema Display + MacBook pro

I just upgraded to Snow Leopard. When I work on my MacBook Pro everything works fine. But when I use through the LED Cinema Display then the machine hangs on several programs, like iTunes, Time Machine, even Finder. Before the upgrade everything worked fine. Anyone having the same problem?

I've had similar problems when using my cinema display. I am currently using it with my usb backup drive disconnected and , so far, have not had the problems. Here's hoping, although it is not a good permanent solution, it means I do not have Time Machine running or access to my other backup files. I suspect that it may be a problem (as reported by others on this forum) with SL mounting a sleeping drive. Time will tell.

Screen resolution problem - HP computer and LED Cinema Display

I just purchased an HP Envy Phoenix H9-1330 with Windows 8, and I connected it to my 27" Mac LED Cinema Display, but the resolution is horrible. The highest option in the screen resolution menu is 1280 x 720, and I'm getting the error message "Your resolution is lower than 1024 x 768. Some items might not fit and apps might not open". How do I fix this? What kind of issue is this (Windows 8? Graphics card? HP can't support my monitor? etc...)?
I just bought another brand new computer, but not an HP, with Windows 8 and I have no problems with the resolution - it looks absolutely beautiful. I want to use my monitor with my HP desktop though.
Thanks for any help

Still haven't figured it out....
BUT I did notice that, on the back of the computer, there are 2 additional DVI connections that are covered with a black cover and screwed in (and they say 'please do not remove'.... I'm asuming it's because they aren't connected to anything? Or maybe they aren't connected to the graphics card?). Is it possible that just my DVI connection is wrong, and I'll need to connect to one of these covered-up DVI inputs instead? But why are they covered up? Do I need to take it in so they can be connected to the graphics card?? Help! I don't want to return this computer, but I will have to if I can't get the resolution fixed.
