Compatibility of Past-Years Cinema Display with Macbook Pro Late 2011, and other displays.

Hello.
I'm inquiring about the compatibility of Apple cinema displays from years past with Macbook Pro 15" Late 2011.
For instance, will all Apple Cinema Displays from, say, 2008 onwards work with my mbook?
They can be had fairly cheaply on the used market.
What is the earliest model that will be compatible?
I've never had an external monitor for my lappies, so I am very clueless. I know DVI is a common connection, but there is no DVI port on my lappie.
I would also be very curious as to what would be suitable displays from other manufacturers, particularly Samsung and Dell.
The size doesn't have to be big, 20-23 inch is fine, I am more worried about good resolution [no obvious pixellation]
If a screen is big, but has good resolution that's even better of course, but I'm not ****-bent on a big thing.
The mbook 15" screen is just a bit squashy for home use really.
Thank you very much in advance for any advice.
Feel free to link me to other threads as an answer, I have done a bit of searching around, but still confused.

I have the same MBP and recently bought a 23" cinema display on Craigslist for $140. It works great. I had a display port to DVI adapter and it worked fine. Built a stand to hold the laptop vertically so it's out of the way. Don't know about older displays but anything with DVI should work fine.
The screen size and resolution are great for photo editing. I now have the best of both worlds, a display that rivals my wife's iMac and portability.

Very different displays on MacBook Pro 15" 2011

I have read a lot of posts stating the new MBP:s screen darker than previous models. I don't know if it's any substance in my remarks but here's my story with my brand new MBP 15" 2,0 GHz. And yea, I know I'm having an issue with wanting my tech things being perfect - especially Apple stuff.
As soon as the unboxing procedure was done and that familiar tune that starts the OSX had faded I noticed the display being not that bright as I expected - the viewing angle was poor, and it had a yellow tint towards the lower part of the screen plus that the panel was brighter at the bottom. Well, I did a thorough research and found out that my panel was labled: 9CA4 - a Samsung panel I think.
I took my new MacBook pro to several retailers here in Stockholm and compared my computer to the units they had on display and there was no doubt about it: They did all have brighter, more neutral screens than mine. I went into their settings and found a different display model number: 9CA3 - LG/Philips (I learned).
Anyway I went to the service desk and showed my findings to them. They could see my point and promised to check with Apple if I was entitled to a change of display. Apple agreed to a warranty change but no one could tell which display I would end up with. To my satisfaction I immediately noticed that the new panel was very much brighter and better looking and yes it was a 9CA3-panel.
I'm sure this is to an extend a matter of personal opinion but it's a fact that the screens could be very different although same year, model, specs and config.

To find the model number you can follow these steps.
Apple menu -> System settings - > Display -> Color -> Open profile (I have swedish os, so the translation might not be right)
Go to line 17, there is the model number.
To find the actual manufacturer of the display, type this in the Terminal:
ioreg -lw0 | grep IODisplayEDID | sed "/[^<]*</s///" | xxd -p -r | strings -6
You will see something like this:
P .00 6
B133EW07 V2
Color LCD
Then google for "B133EW07 V2" to find the manufacturer.

EXACTLY what cable(s) do I need to connect my MacBook Pro (early 2011) to an external display with a 2560x1440 resolution?

I am trying to connect my MacBook Pro (early 2011 w/ Intel HD 3000/ 384Mb) to an external display with a 2560x1440 resolution. Specifically, what cable/connections do I need to display at this resolution? I cannot get the display to work using a "Thunderbolt to HDMI" or a "Thunderbolt to DVI" connector. Note: I used both older and newer (uni-directional) HDMI cables on the first config, and a Dual-link DVI cable on the second config. Apple specs state this is possible ( support.apple.com/kb/SP619 ), but I am at a loss as to how this can be done. Thanks in advance for the help!

You use a Mini DisplayPort to either HDMI or dual-link DVI adapter. If that component doesn't work, something's wrong with either the cable or something else in the connection.

13" MacBook Pro (Early 2011) doesn't detect display over mini DisplayPort HDMI adapter in Mountain Lion 10.8.2

Hi to all.
I have a problem connecting external display (Dell U2311H) to my 13" MacBook Pro (Early 2011).
I use Tecklink Mini DasplayPort to HDMI adapter (http://www.techlink.uk.com/products/wires_cables/wiresmedia/wiresmedia_media/wir esmedia_mini_displayport_plug_to_hdmi_plug), but since U2311H doesn't have HDMI input, I also use Manhattan DisplayPort to HDMI Adapter (http://www.manhattan-products.com/en-US/products/8101-displayport-adapter).
And nothing.
The display is not detected, no picture or even external monitor presence at all.
I even reset PRAM, and installed 10.8.2 Supplementary update.
I also plugged and unplugged all I could, with no luck.
As I can see on Apple discussion, it is a common problem with 2011 MacBook Pro's.
It seems like the problem is in Thundebolt port, it somehow does not work properly.
If anyone has solved such ploblem, please let me know.

In reply to my own post have to say appologies to Apple whose Thunderbold port I used to blame.
Shame on me)
So, what was my problem?
Guess what?
Manhattan DisplayPort to HDMI Adapter !
The point is it's actually do only what it said to do, converts DP to HDMI.
But I for some reason thought it can be used vice versa, to be HDMI to DP converter))
I was wrong.
I bought new one HDMI to DVI adapter and now I HAVE external display!
Thunderbolt works like a charm.
So I'm very satisfied now.

How do i use my imac 21.5" 2011 as a display for my macbook pro late 2011, through thunderbolt cable ? I have tried and it doesnt seem to work, neither does target disk mode.

How do i use my imac 21.5" 2011 as a display for my macbook pro late 2011, through thunderbolt cable ? I have tried and it doesnt seem to work, neither does target disk mode.
Could it be a borked cable ? I just bought it new from the store today, i have updated both imac and macbook pro to latest thunderbolt firmware and updates. Both 10.7.3.

You are correct, here is what Apple Says:
http://support.apple.com/kb/TS3775
I was able to find these instructions, however they referr to 2009-2011 27" iMacs. I think it's the same, if it's not then contact Apple directly for instructions. If either of the machines is less than 90 days old or covered by AppleCare then call AppleCare tomorrow for help, they should be able to easily answer this for you. You will find the number in your manual or you can use the AppleCare Contact Info link.
Your iMac should automatically recognize the presence of a digital video signal at the Mini DisplayPort and enter Target Display Mode.
If your iMac does not automatically enter Target Display Mode, press command + F2 to manually enter Target Display Mode.

I have a Macbook Pro Early 2011 from the USA. After installing Mavericks, Adobe CS6 crashes whenever it is plugged into a 27inch cinema display I purchased from the apple store in China (We moved to China). It works when not plugged into 27inch display.

I have a Macbook Pro Early 2011 from the USA. It is now running Mavericks. I connect it to a 27" Cinema Display that I bought in China after we moved to China. Before I installed Mavericks, I could run all of the Adobe CS6 and Adobe CS5.5 applications on my Macbook Pro while connected to the cinema display. Now that I have Mavericks installed, whenever I am connected to my 27" CInema display my Adobe applications crash upon opening. I know this is a rare scenario, but does anyone have any ideas how to fix this problem? Is there a new driver that needs installed? I'd appreciate any help.

I am also having a similar issue. I used Adobe Lightroom and my whole display goes black. Even my laptop screen and the lights on the keyboard go black. I can still hear the fan running, so I assume it is just the display. This is my first Mac and I have had nothing but issues. I think I am going back to Windows after this.

Macbook pro thunderbolt 2011 won't detect display

I am working on a Macbook Pro, October, 2011 model with a thunderbolt port. I have now gone through two thunderbolt to HDMI cables and neither was able to detect my display, which is a Sony Bravia. Should I throw in the towel and buy a $50 (rip-off) cable from Apple, or could it possibly be that my port is faulty? Anyone with a similiar problem?

No, don't buy expensive cables. Do you have a url (link) to the cable you are using?
On what basis do you think that your computer doesn't detect your TV?
If you opened Displays system preferences, click Detect Displays. Is there an Arrangement tab and an does it show two monitors? If not, then there is indeed a physical problem Make sure the cable is fully seated in the HDMI on the TV and the TB socket on the computer and also make sure your TV is set to take input from the HDMI input port you connected the cable to.
If the Arrangement tab is there and shows two screens click Gather Windows. This should bring the Displays preference window for the TV on to your main screen. Then set the resolution (probably 720p, 1080i, or 1080p) and refresh rate (probably 60Hz). At this point you should see a picture on your TV.
You may have to play the underscan/overscan settings on your TV and the displays prefs for the TV if the picture is too small or larger for the TV screen. If Sony's haven't changed they may call it "full pixel".

Macbook pro mid 2011 battery lasting only 3 hours

How can I get my brand new Macbook pro mid 2011 battery to last longer, now it's lasting only 3 hours.

Do not believe the advertised specs from any manufacturer regarding battery life. In the real world expect about 60% to 70% of those figures. Battery life is influenced by many factors, Among these are display brightness, the number and type of applications you are running, if the optical drive is used, external devices that may be attached etc.
3 hours seems a bit low but not necessarily out of line. Go to SYSTEM PROFILER>POWER and see what it says by 'Condition'. If it is other than 'normal' you may have battery issues (Explanations then can be found in FINDER>HELP).
Ciao.

Both Internal hard drives fail on Macbook Pro late-2011

Both internal hard drives (SSD and HDD) failed on Macbook Pro late-2011.
Setup: MBP closed with Thunderbolt display attached.
Problem on HDD-A
I called Apple Support to log an issue with my MBP2011. The system is made up of 2 drives - SSD (128GB) and HDD with 2 partitions HDD-A and HDD-B(original 750GB).
HDD-A has LionOSX 10.7 and HDD-B is storage. SSD has LionOSX on it as well. I normally boot HDD-A.
I was working on HDD-A and the Kernel Panic screen appeared prompting me to shutdown the machine and start it up again.
I tried to reboot HDD-A and the grey progress bar appeared for a long time. I then forced shutdown and rebooted into SSD.
I was able to boot from SSD and then I opened Disk Utility to check the drives. I verified the disk for HDD-A and there was an error. I then tried to repair disk and it couldn't repair it. A dialogue said the disk could not be repaired and that data should be backed up.
HDD-A was not visible in Finder but HDD-B was accessible.
I verified HDD-B and it was "ok".
I shutdown, booted from SSD, disk utility HDD-A and the same message occurred.
I called Apple Support and they advised that I boot from my external HDD which was a clone of HDD-A.
Solution
I was successfully able to boot from the Clone HDD-A.
HDD-A was able to be accessed and I could retrieve the files from HDD-A.
I copied over the latest files from HDD-A to an external drive.
Same Problem on SSD
Boot from SSD, i started working for about 3 hours, with the lid closed, and attached to the ACD.
Kernel Panic screen happened again on the SSD.
Couldn't boot boot from either SSD or HDD-A.
I booted from Cloned HDD-A, Disk Utility verify and repair returned errors on SSD. The same issue had occurred on the second drive.
Disk Recovery from a boot recovery USB thumb, Disk Utility, erased SSD, verify was ok.
Tried to install then there was an install error saying that SSD was damaged (large triangle warning icon). Tried 3 times, failed.
Boot from Recovery Drive HDD-A, downloaded LionOSX.
Next steps
Format HDD-A and HDD-B into 2 partitions
Install LionOSX on HDD A.
Note:
I did not do any software updates for about a week before 14.04.2012 and suspect it might be due to the virus.
I normally work with the lid closed and attached to the ACD, I also suspect that overheating caused both drives to fail. However, I have been using this system with the lid closed for atleast a week. One Kernel Panic screen occured.

Depending on what you are doing on the computer, how hard you are working the computer, it should not overheat. And if it does it should shut down or get very slow because when it starts to overheat the CPU will be throttled back to a lower Ghz speed and or just shut down so it doesn't cause damage to the CPU. The Kernel Panics are a sign that something else is going on. This could be software or hardware.
If after wiping the drives and reinstall Lion on the SSD if the system is running OK then the drives are fine, IE they are not bad. There is something else corrupting them. Again this could be hardware or software, but I doubt it is heat. And using the MBP ion clamshell mode should not cause overheating or excessive heating of either of the drives.
Have you installed iStat Pro or Menu and kept and eye on the temps? If not install iStat Pro and keep and eye on the temps. I bet they do not get above the 150°- 180°F mark which although hot is not overheating.
Be very careful when calling Apple. Removing the DVD drive and installing a hard drive in that bay could void your warranty. The DVD is not a User Removable part and Apple frowns on doing that. So if you call them do not mention that you have replaced the DVD drive with another HDD.
Honestly I suspect you have a hardware problem. But the only way to know that is to install just Lion and your basic programs and run the system. Leave out any AV type software, if you are running some. If you don't get any kernel panics thenn install some of your other software, one programm at a time. If with just the OS and basic software you get a kernel panic then it is hardware related and needs to be checked out by Apple. If you do that re-install the DVD and the original HDD with just the OS on it before you take it in.

Macbook Pro late 2011 suddenly slow after months using Yosemite. Never noticed kernel_task until this happened.

My MacBook Pro late 2011 has recently slowed to snails pace after successfully running Yosemite from a clean install for many months.
I always have Activity monitor running to keep an eye on memory and CPU. When the issue started, I noticed Kernel_task for the first time and its 0.5 to 1GB.
I have verified/repaired the disk and repaired permissions in Safe Mode. Also done SMC and PRAM resets.
CPU usage is usually 2% or less unless number crunching in Excel or watching videos.
I created a new user account, which is much faster in opening Safari and searching. There is no Kernel_task showing for the new user.
Cardo-updater is for a motorcycle bluetooth headset.
Xquartz is for GIMP.
Rogueamoeba is for Audio Hijack Pro.
These three have been in use since day 1 of Yosemite and before in Mavericks.

Oddities - I don't know what the disk info not mounted means. Not mounting the Recovery disk looks scary to me as uninformed.
Time machine disk too small - thought I was using a 1 TB drive !!
Problem description:
MBP late 2011 has become very slow after a few months after a Yosemite clean install. Kernel_task memory circa 1 GB. CPU activity is a few percent. Created a new user. Activity monitor does not show Kernel_task at all. Much faster as the new user. Permissions repaired in Safe mode. SMC and PRAM reset done. Short hardware test (option D on boot) - no problems. I have VirtualBox to run XP at times for some Win apps.

Macbook pro late 2011 starting problem

I'm running OS Maverics 10.9.3 version on Macbook pro late 2011. Few days ago the OS got much slower than normal system. Then i installed the the new OS but it was good for few hours. Then after few hours it became slower again. Then I changed the HDD and installed the new OS. But I found the same problem again. Then I removed all backup files from the HDD. After removing all items it became to work normally. But after 15/17 days later when i'm trying to turn on the macbook a flashing folder icon appears then i pull down the display for a while. When the lights gone then i turn on again and it works normally. I tried the internet recovery option by pressing the (ctrl+R) button but it takes much time. But nothing happened. What is the problem?
Here is my etrecheck result:

Try this:
Boot into recovery (OPTION key down) and select the recovery partition.
From the 4 option menu select Disk Utility.
Run Disk Utility>First Aid, Verify and Repair.
If it says the disk cannot be repaired, replace it with a new HDD.
If it says it is good, take out the disk, place it in an enclosure and connect it to the MBP via USB.
If it boots the MBP, then the internal SATA cable is faulty and should be replaced.
Ciao.

Does airplay mirroring work on MacBook Pro late 2011 ( Mac OS X Lion 10.7.5)?

Hi guys,
I would like to use airplay mirroring on apple tv (3rd generation) with my macbook pro late 2011, unfortunately the airplay option does not appear in the display preferences (see screenshot below). Did someone have this problem before? Please advise!
Thank you!
Tial

Welcome to the Apple Support Communities
See > http://support.apple.com/kb/HT5404 Your computer is compatible with AirPlay Mirroring, but you have to upgrade to OS X Mountain Lion to get AirPlay Mirroring.
Make a Time Machine backup and/or a clone with Carbon Copy Cloner, open App Store and purchase Mountain Lion. When the download finishes, the installer will appear, so follow the steps to upgrade. To turn on AirPlay Mirroring, select the AirPlay icon in the menu bar or open System Preferences > Displays
