Display Issues on Early 2011 Macbook Pro

I am currently experiencing an undocumented problem for my 15 inch Macbook Pro (Early 2011 Version), and was hoping to get some help diagnosing what the issue might be.
Lately, it seems that whenever I am doing anything that is computationally expensive (i.e. streaming video using Flash or Silverlight, or using parallel processing in MATLAB), my screen goes haywire and shows up noisy green lines on anything that is supposed to black. Similarly I get noisy light blue lines on anything that is supposed to be white. I am including a pictures below to illustrate the issue.
I have tried several fixes, but nothing has worked to day. Changing the color profile does not change anything. Taking a screenshot does not change anything. Also, the issue seems to pop up regardless of whether or not I have the onboard graphics card enabled. I am also fairly certain that this is a hardware issue, since I reinstalled Lion and updated all of my software after it first started happening. 
I would appreciate any input in regards to further diagnosing the problem. I have an appointment coming up at the local Mac store, but I'm almost dreading going in since I do not want to have to send the computer in for repair.

i've done a complete rebuild back to 10.6.8 and found that both problems appear to have disappeared, both screen and TV working again since this morning without seeing any issues.
I'm now installing Lion to see if it returns.
the only difference will be that I'm not going to install bootcamp until later, this will be a clean install as before I installed Lion on a previous version of 10.6.8 with bootcamp etc already installed.
maybe this will work, wish me luck

    Do Not post stuff about how Airplay doesnt work, because i dont have Apple TV and dont need to hear about it.

    If you have an external drive equal to or larger than your internal HD, clone your internal to it with either Carbon Copy Cloner or Super Duper. Test the clone to make sure it's bootable. Then upgrade either one. Try it out first.

  • Can I hook up an early 2011 macbook pro to a new iMac AND another thunderbolt display?

    I want to get a new iMac, and I have an early 2011 macbook pro.  Can I use a two-way thunderbolt cable to hook these two up?  If so, will I still be able to use full functionality on both as I move windows to and from one of them?  (Like, I use my macbook track pad to move a safari window over to my iMac, and then I can either use my iMac mouse or my macbook's trackpad to do things with that safari window.
    ALSO, is it possible to hook up an additional thunderbolt display to all of this?  Basically my end-goal is to have a macbook pro hooked up to an iMac with an additional thunderbolt display, that's my "dream set-up" which will make a lot of stuff that I do a lot easeir and less crowded on one moniter.

    no the thunderbold display thing would let you use the imac as a monitor for the macbook apart from acting the role of display the imac would be dorment so a very pricy monitor

  • My early 2011 MacBook Pro 15" non-glare display has developed a dark band at the edges of the screen approximately the same width as the aluminum surround. This wasn't present when the MBP was new. Am near an Apple Store, but anyone else had this problem

    My early 2011 MacBook Pro 15" non-glare display has developed a dark band at the edges of the screen approximately the same width as the aluminum surround. This wasn't present when the MBP was new. I'm near an Apple Store and can take the laptop in, but has anyone else had this problem?

    Thanks for your input. I didn't completely flesh out what I'm seeing visually. The resolution settings are all correct for my screen. The problem is if, say, looking at the gray startup screens or a completely white full-screen image, there is a perimeter of graying, almost as if the LEDs are somehow not as bright as the rest. It's also curious that the thickness of this phenomenon is almost exactly the same as the metal bezel around the display. I will be taking it to an Apple Store for a look, as I'm also having several minor hardware problems that need to be addressed and remedied.

  • How can I connect my Early 2011" Macbook Pro 13" inch, with a generic Mini Display Port to HDMI connector, to a LG 32LD340 LCD TV, using Mountain Lion 10.8.2?

    I have an Early 2011" macbook pro 13 inch (core i5 2.3ghz 4gb ram 320hdd) with Mountain Lion 10.8.2, and I want to connect it via Mini DP to HDMI connector, and a HDMI cable to a LCD TV LG 32LD340. When I had Lion OS, I had no problems at all.

  • Early 2011 MacBook Pro- The thermal paste discussion.

    It is my goal to clear up the questions and concerns Apple customers have been having regarding heat or fan related concerns with Early 2011 MacBook Pros. If your MacBook Pro was produced within the last few months the thermal issue has been resolved and it will likely not be in issue for you. If you are still wondering if your computer is effected or what the real issue is keep reading.
    The MacBook Cools itself by 2 main methods: active and passive. The active cooling is via a fan that blows air through a heatsync and into a tube called a heat pipe which leads to the back of the computer where the hot air is discharged through a vent at the bottom of the screen behind the hinge. The fan lowers the air pressure inside the case causing outside air is drawn in the case, displacing the hot air inside and helping to cool the other components.
    The computer uses passive cooling to remove the residual heat from the processor which comes mostly in the form of radiant heat. Passive cooling is also used to cool the other components of the computer (memory, disk drives, battery etc). Passive cooling works by conductive heat transfer ie. syncing to the case of the computer. Some of the heat then is radiated. Some of it is transferred from the outside of the case via convective cooling; the foot pads on the bottom cover are designed to raise it up just enough to allow air underneath for convection to occur. (Convection is the process in which hot air to rises and is displaced by cooler air.) The rest of the heat from the bottom cover is absorbed by whatever surface you have the computer on.
    The processor will not sync to the case very much if the board is assembled properly however the other components of the computer will, requiring the case to be in open air to allow for passive cooling to take place.
    If you have some sort of covering such as a plastic snap on case it will likely interfere with passive cooling in all of it's 3 of it forms, this will cause the computer to be abnormally hot. I recently saw someone in the Apple store with a MacBook Air experiencing abnormal heating due to a plastic snap case so this particular problem is not unique to MacBook Pros and it is not the cause of the issue being discussed here. I do not recommend the use or anything that covers the computer while it is running with the exception of something that covers the back of the display panel only. If you are worried about your computer getting damaged go and buy a laptop insurance policy from Worth Ave group. The insurance does not cover cosmetic damage or misplaced items but will cover accidental damage including spills. This insurance also covers theft, vandalism and natural disasters, is quite inexpensive and the claims process and deductible  is similar to most phone insurance plans (which they also offer).
    User induced overheating can also occur when the computer is placed on an improper surface such as a couch cushion, car seat, bed, pillow etc. Doing this can interfere with both passive and active cooling.
    As I mentioned earlier In all likelihood if your computer was produced after May it is not affected. I personally have been in posession of 3 MacBook Pros, one produced before May which had the problem, one after which had no problems and one produced more recently that has mind blowing thermal performance way beyond all of my expectations.
    So the question at this point is exactly what is the problem, how can it be diagnosed and how can it be rectified.
    After extensive research and testing I have determined the issue to be related to improper application thermal paste. I involuntarily became involved in this pursuit as a result of the problems I was experiencing and I did not initially come at from an objective viewpoint but rather one of cautious skepticism. I had anticipated before purchasing my computer that there may be a thermal issue. This anticipaion came as a result of reading an article on ifixit.com about the disassembly of the brand new early 2011 MacBook Pro. When the technician performing the disassembly removed the main heat sync he expressed concern about how much much thermal paste was present, expressing that it seemed excessive. This lead the technician to question wether or not it would cause heating problems.
    Proper application of thermal paste is critical to the functionality of the active cooling system and when applied improperly will not properly transfer the heat to the heat-sync which in turn gets cooled by the fan. Proper application of thermal paste insures the heat is removed from the case as efficiently as possible. Doing this both reduces the speed at which the fan needs to run in a lot of situations and prevents too much heat from the processor needing to be cooled by passive means. If is is not applied properly it will eventually lead to overheating of the case as well as the other components of the computer. This can cause damage firstly to the computer's battery and can also significantly shorten the life computer. (Or any other kind of electronic device for that matter.)
    The problem can be diagnosed by testing the computer using a program called System Load or any other software that will put your computers proscessor use up to its maximum and keep it there indefinitely. Placing full load on your GPU at the same time during the test is also recommended. Keep in mind, if you are using your computer the fan will spin up if needed for additional cooling. You should expect the fan go up to its maximum speed during the test, it is not in of itself an indication of a negative result. Make sure to have the computer plugged in, fully charged and on a proper surface. A desk or other flat surface should be fine. Exceptions would include the top of a refrigerator since it has insulation just underneath the metal exterior or any surface that is heated by any means such as a dryer or other appliance.
    (The temps to follow are in ºF)
    Run the test for up to 1 hour. If the case of the computer breaks 93 degrees your unit is likely affected. Expect the unit to even possibly reach temps approaching and exceeding 100º, if this happens immediately abort the test. Also look for the processor temp shooting up to around 180 in the first 30 seconds and the fan spinning up right away. Typically on a properly functioning unit the temperature of the case will end up being somewhere in the neighborhood of 88-91º. If this test is preformed in a room with a normal ambient room temperature of about 68 degrees. Even after an hour the case of the computer should not be significantly hot, just warm to the touch. On a normally operating unit the fan will start to kick in within 90 seconds or so and may not reach full speed even after several minuets.
    At one point the case of my computer actually reached 95º during normal web browsing.
    This is a problem that I have had successfully corrected twice by reapplication of thermal paste. The first time was on a machine produced prior to may and the second was after a logic board was replaced at the repair depot. (I suspect the inventory turnover is lower for boards than whole computers resulting in a board from the initial production run being installed in my computer.)
    If you forget everything I just wrote remember this. #1 if you are using your computer hard enough the fan will end up running at high speed at some point. #2 This problem is not in any way related to the design of the MacBook Pro, or its use/application. #3 This mostly not a problem of the CPU being too hot; these Sandy Bridge CPUs are rated for 212ºf and will routinely be in the neighborhood of 200º, this is hotter than other chips but well within design limits. #4 I have done everything in my power to make sure that this problem has been corrected and I have every logical and evidenced based reason to believe it has been resolved in machines produced after may. #5 This is not an Apple acknolidged issue. Technicians will tell you that there is no problem because these higher temps are normal and within operating limits and if they weren't the machine would shut itself off. (This is a bit extreme; just like a lot of other devices such as electronics, toaster ovens and space heaters with thermal overload protection this automatic shutoff is intended to occur when damage or risk of fire is imminent because the device is WAY outside of normal operating paramaters.) They will also not tell you when asked what these limits are, that they know what they are or in some cases that such figures they even exsist.
    I stake my personal and professional reputation on the accuracy of my findings, it is my job as a private consultant to help my clients to resolve complicated and expensive issues just like this one.
    Bottom line if you are having a problem and Apple won't fix it on warranty don't ditch your machine, just pay to have it done yourself. In most cases you can pay have it done at the Apple store. It will probably cost you less than 100.00, and it will not void your warranty as long as the work is done by Apple certified technician. It will be well worth it; after all in spite of this MacBook Pro's are hands down the best portable computers on the market, with an industry leading warranty and support to back it up. On it's worst day Apple's service and support is better than any computer/ consumer electronics company, even on its best day.
    I hope this helps to clarify this issue! I also hope it will help anyone affected to resolve the problem instead of resorting to a refund and settling for something else.

    hello all
    you can try this:
    Go to system preferences > settings > built in display >  see bottom of window.
    check "show mirroring options in the menu bar when available". then click "airplay display" > and select your device.
    That's what happened to my MBP - 15-inch, Late 2011 model.

  • Early 2011 Macbook Pro - Black screen at random

    I have an early 2011 Macbook Pro, running Mac OS X (10.7.5). Seemingly at random, the screen will go black and the only way to get it back is to hold the power button down. When it turns back on, everything is running as normal. It's been happening more and more frequently, so I'm wondering is this a problem I can fix on my own? Can it be fixed or is it just a glitch I should just deal with?
    (Please explain everything to me as if I were a 5-year-old)

    Early 2011 15" Macbook Pro.
    Add me to the long list of customers experiencing display issues.  HUGE problems with a blank screen when waking from sleep and difficulty starting up (video glitches & hi fan speed).  After about 6 months and 2 genius bar visits I finally did a complete HD wipe/clean install of Mavericks with all of the default settings.
    The situation has improved only slightly overall, but at first things were great.  I was confident I had it licked.
    As I restored apps & profile settings things start to get wonky.  The last install I did was Picasa (I thought this app was the culprit before the wipe).  I successfully restored my Picasa settings and all was fine.  I even closed the lid and when I opened it the next day the screen came right back on.  Then I tried to sync my iPhone and BAM!  Screen goes out and the system is hung (no response to keystrokes or sound events).
    Power button shutdown.
    Restarted and the Macbook hung as the previously opened apps reopened.
    Power button shutdown again.
    Restart this time was normal and everything opened just fine.  The console logs show NOTHING indicate any issues or that the machine experienced a kernel panic or anything like that.
    It's been 1 whopping 36 hours since my clean install and I've already crashed twice. 
    But now I use my Macbook with anxiety as I never know when it's going to crap out again.  Maybe it's time I switch back to Linux on an inexpensive wintel laptop as I won't buy another Apple laptop if this is the what I should expect from a $2000 machine.
    Incidently, I also have a 2010 MB pro which had dispaly issues and Apple replaced the logic board at no cost (out of warranty) as part of a replacement program.   I've seen MANY forum posts suggesting that Apple should step up and provide the same level of service for the Early 2011 MB Pros...  I tend to agree.

  • Problems with early 2011 MacBook Pro 13" 2.7 GHz / OWC Mercury Extreme Pro

    *Has anyone else experienced issues getting their OWC Mercury Extreme Pro SSD working in the early 2011 MacBook Pros?*
    I am having difficulties getting OS X installed on the new OWC Mercury Extreme Pro 240 GB. When I install the SSD in place of the factory HDD and boot from the 10.6.6 reinstallation DVD the SSD is not visible to the installation program. If I quit the 10.6.6 installer and run Disk Utility (from the 10.6.6 installation DVD) the SSD is not visible. If I quit Disk Utility and run System Profiler (from the 10.6.6. installation DVD) the drive is visible and firmware and serial numbers are displayed. So like the drive is visible to OS X but the installer / Disk Utility can not see it.
    If I put the SSD in an external USB enclosure it is visible - I can format the drive and copy files to it.
    I also tried installing the SSD in place of the factory HDD, putting the HDD in a USB enclosure, booting from the OS X installation on the HDD and running the OS X installer from the 10.6.6 DVD. I was able to select the SSD as the target for the installation and the initial file copy was OK, but when the laptop restarted during the installation the SSD would not boot. The grey folder icon with the flashing question mark was displayed instead. Holding down Option while booting only gave me the option to boot from the DVD.
    I also tried resetting the NVRAM and SMC of the MacBook Pro - this did not resolve the issue.
    I spoke to OWC support who said they did not know of any compatibility issues with the new MacBook Pros and suggested I request a replacement.
    The firmware version of the SSD is 350a13f0

    This is my exact problem. I have had 2 of these drives so far and both of them have had the same problem with installation internally. The first one I was able to get operational using the method you described, ie: put the OWC SSD in an external case (FW800 was my choice) and install it there. But I encountered the sleep issues, so I sent it back for a replacement.
    The second drive I was finally able to install using the second method, but now the computer regularly locks up. So I'm going to call again and hopefully the third try will work.
    Just to clarify. The first drive had sleep issues, but had the older firmware. The second drive had the newer firmware (360 I think it is) and didn't have the sleep issues, but locks up while running.
    I'm so irritated on how many hours I've spent on this issue. And their support department, though very nice, wasn't helpful at all. It's as if they never heard of this problem.

  • Is there any way to make a snow leopard partition on an early 2011 MacBook Pro that was upgraded to Lion, without the original boot disk?

    So I have an early 2011 MacBook pro,  I believe it shipped with snow leopard originally, as I purchased and upgraded to Lion fairly early on.  I am trying to make a partition right now and have it run snow leopard so I can use programs that have PowerPC.
    I should note, I replaced both the RAM and the harddrive in my Macbook pro.  I changed from 4 GB of ram (that came shipped) to 8 GB of ram from a 3rd party, that I installed on my own months ago, have registered in the computer and have been working fine for quite some time now.
    Also I should note I replaced my harddrive.  I went from what ever the standard 500 GB harddrive that shipped with 15 inch early 2011 MB pro's.  I now have a 3rd party SSD that's 240GB's that I also installed on my own, (at the same time as the RAM---Black friday items)  The harddrive has been working just fine since then.
    In installing the harddrive I borrowed a friends external harddrive and used a program called carbon copy cloner to get everything over to the SSD.
    Now here is my issue.  I have ordered the Snow Leopard (10.6.3) install disks from apple, I have created a partition on my SSD for snow leopard, but when I try to select the install disc for snow leopard at boot I get three beeps.
    I know this issue has been posted elsewere but it said answered and the answer is no longer available.  I also am unsure if any of the RAM or Harddrive swapping could have been causing the issue.  I have the old harddrive and RAM still, but unfortunatley have no external harddrive anymore or money to afford one.
    Is there any way I can install a partition that runs snow leopard on my early 2011 MB pro with what I have (new SSD, New RAM, Current version Lion running, no external drive, lack of original snow leopard disks [I lost them ] and the general 10.6.3 snow leopard boot disks).
    Let me know If there is anything I can do.  I'm a now broke college student so i'd like to spend as little $$$$ as possible
    *PS I should also note the DVD drive is working fine, it reads the disk, the disk is brand new, it plays DVD's fine and has never had any issues in the years i've used it for similar tasks*
    sorry for the long drawn out post, I just wanted to include as much as possible from what I've seen other people have issues with

    As the last post suggests, call Apple and order a replacement original disc for about $17.  They will ask you the model and serial numbers.
    Your retail version of Snow Leopard OS 10.6.3 will not work on that Mac as it requires a minimum of OS X 10.6.7 to boot and operate.
    Another alternative is to again borrow another Mac to install your retail Snow Leopard into an external HD or partition, upgrade it to 10.6.8 and then clone it back to a partition on your MBP.

  • If I buy an external monitor (with a res of 2560x1440) will my early 2011 MacBook Pro work ok? And will it be utilising the monitors full res or not?

    Hi,
    I have an early 2011 MacBook Pro. I use Premiere Pro CS5 to video edit on. It's fine but when it comes to grading it's nearly impossible on such a small screen.
    I'd like to buy a 27inch external monitor (Asus, Samsung, Dell, whatever - haven't decided yet) for when I'm editing at work (which is most days). My query is regarding the resolutions. Obviously my MacBook Pro displays a resolution of 1280x800, so if I buy a monitor with a resolution of 2560x1440 for example, what gets displayed?
    And also does the connecting cable make any difference? For example, if I'm connecting by Thunderbolt out to HDMI, then an HDMI to HDMI cable to the external monitor, what happens then? Or should I be using a Mini Display Port to Display Port connecting lead?
    I guess all I really want to know is, will it work? But also, am I wasting my money buying an external monitor with a 2560x1440 resolution? Should I just go for one that's the same res at my MacBook Pro?
    I've never really understood how these things all work!
    Thanks in advance for anyones help.
    Regards,
    Phil   

    I think it will work.  You would need a mini displayport to (single link) DVI adapter to hook up that monitor.
    Not sure what kind of problems you had with the ViewSonic but I'm guessing the Dell is probably a better monitor anyhow.

  • Early 2011 Macbook Pro GPU

    I know this question has been asked before. My problem is similar to what is mentioned here but I hope someone can explain the error log attached below and hopefully I'm able to find a DIY solution without much cost.
    I'm using a early 2011 MBP with Yosemite installed. Not too long ago, I manually upgraded my hard disk to a OWC SSD.
    Recently my MBP screen went into white blank screen AGAIN while I was working on a python script which crawls the web with about 10 threads. I used to run this same script without *much* problems before yosemite (ie: i encounter the same problem with Mavericks but not so frequent. I never install mountain Lion before so I can't comment on that. I came from Snow Leopard to Maverick and Yosemite). Other times, my MBP will go into the same white blank screen while doing other misc stuff and this usually doesn't involved me watching any HD video.
    A couple of solutions that get my MBP up and running are:
    1) I hard shutdown and bootup my MBP. After the apple logo it freezes at the white blank screen. While it stays in the white screen, I will unplug my power adapter and wait for my battery to drain out completely. Once the battery is completely drained out, I will plug in my power adapter and I'm definitely able to boot up my MBP without any problem the first time. I did the same and thus I'm able to post this question.
    2) Bootup into safe mode and restart. It works once
    3) I have also disabled dynamic switching of graphics card but that didn't work.
    Below is my error report. I don't quite understand it. I hope someone explain to me?

    Hi all, I had many problems with the GPU of my Early 2011 MacBook Pro and the MLB was replaced three times so far. The first time was about a year ago and I went to an authorised retailer and not to an Apple Store. They first incorrectly diagnosed the problem and told me that they had to replace the hard drive. After that, they still did not really find the problem but said that the MLB had to be replaced, which I did given that my computer was only two years old and running fabulously. About a month later the problem reappeared and the MLB was replaced again, this time by using the 3-months guarantee of the MLB. The first time I had to pay. A few weeks ago I again had problems (the computer was very hot and fans were running at maximum speed most of the time although I was running only Mail and Preview). I'm, I took it directly to the Apple Store and after about five minutes of looking at it they decided to replace in the MLB for free. There is no official replacement program but I think Apple has now recognised the issue and they don't charge you anything if you had the issue before (they call this a repeat repair). So good luck if you haven't solved your problem yet. If the problem reappears there should be no problem.

  • My Early 2011 Macbook Pro Continues to shut off at random

    I own an early 2011 Macbook Pro, 4GB RAM, intel 3000 384mb graphics, 250gb SATA hd. I now have OS X 10.8.2 and my macbook randomly shuts off and its not just once or twice a day. It is more along the lines of over 20 times a day. Can somebody give me some advice to resolve this issue? I used mackeeper and ran every scan and I went to disk utility and repaired the drive. I don't know what else i could possibly do. This issue is making me wish i never bought this mac. The macbook is great and all but now i can't even use it because it shuts off at random. I can't enjoy the macbook if i have to use it in fear that it will shut off at any moment. Can someone please help me with this issue quickly?

    If you have Apple Care or are still under warranty, give them a call and get a case number.  Otherwise, take the computer to an Apple store or an AASP.  Whichever is more convenient for you.

  • Will a early 2011 macbook pro run ml airplay mirroring

    Will an early 2011 macbook pro run airplay mirroring on moutain lion

    Only thing I would add if I was you, would be to put 8GB RAM into your machine. That will help any issues of being slow, but it should run just fine. Having more ram is always good, and for the price point its well worth it.
    I have on 2010 Macbook Pro and it screams. Also on 2011 Macbook Air with no issues.
    As for running slow, it could incompatible apps, or apps that havent been updated yet, it would be impossible to pinpoint one thing.
