Imac Rev 11,3 display flickering at random intervals

Hi,
I searched a fix for this and returned 2 results both of which produced error "software not for this machine" when attempting to install.
It would appear that apple thinks the problem might only have affected the previous 2 revisions - are any of you encountering the same issue with this revision.
Description of the problem: I can be working on the machine for any amount of time and the display will suddenly go very bright, and then back to normal, this could happen again immediately or a few seconds later or even only a few hours later.
The machine is the 11,3 rev iMac core i5 quad, serial starting with W80445. I have only had the machine for 2 months. All software is up2date.
Any suggestions would be appreciated.

Apple support reset the SMC (plug out power and peripherals and hold power button in for 15 seconds to rid residual charge) and PRAM (Startup with OptionCMD+PR,release on second chime), however the problem still exists, so I will have to return the machine again.
I will update this with further feedback once the techs have reviewed the machine.
Thanks to those who replied.

My macbook air (version 10.9.4) display flickers, has random tabs and windows opening, and there are random ads almost everywhere. All this happens when I am using safari. What can I do?

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can read it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start Time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

IMac 27' Mid 2011 display flickering and going dark

Having bought an iMac 27' in may 2012 I was confronted with a flickering of the screen and the display eventually going dark for a certain amount of time.
Unfortunately the first level support wasn't helpful and the second level support rather rude.
Have taken the iMac to the seller I was told they would have to change the display for € 700,-. Apple would refuse to extend the one year warranty though other people have encountered the same problems obviously after checking in different support forums.
So did anyone find a cheaper solution then just to exchange the whole display? Having to spend half the prize of a new iMac can't be the answer.

Yes, the light comes back after a few minutes or half an hour.
Will try take a screenshot when the display is off again as soon as I get the iMac back from the workshop.
I have decided not to spend so much money on the replacement of the display for the moment. If the light goes off more often I will buy another display (probably a non-apple-product with a better warranty) and connect it to the iMac.
As much as I love the concept of the apple products and the idea of an All-In-One computer (it's my 7th apple in 25 years), I really disliked how they treated me as a customer with a valid complain.
If it just this little cable why would Apple replace the whole display? I'll check if I can fix it myself then.

Imac 21.5 (ver 10.6.8) Display flickers and it goes blank

Display flickers and its brightness automatically increases and decreases intermittently. After some time the Display goes blank and it doesn't appear even after pressing the power button or restarting the PC. At times it does appear after pressing the power button frequently or if the PC is left ON for some time. I am using software ver 10.6.8. Want to whether this problem will be resolved after upgrading it to Mavericks. But I am worried that during the downloading if the display goes off and if I have to restart the PC then I will have to start the downloading from the beginning. Please suggest.

If you live near an Apple Store, make a Genius Bar appointment to have the computer tested. Supposedly there is no charge for testing. Use 2nd link if not near an Apple Store or aren’t in the US.

External Display Flickers (Intel on board)

Hi,
I have recently made a fresh installation of Arch Linux and trying to setup it for my work environment. I made a basic installation of xfce4 with slim login manager. I wanted to hook my laptop with an external display. I used xrandr to extend my laptop display with the external display. Everything worked fine but my external display flickers insanely bad. I cannot stare at it for > 30s. I dual boot on windows, so I tested the same setup with windows and it worked just fine, out of the box. I even used one of my friend's laptop who's running ubuntu and has the same h/w. It worked out of the box. I have spent more than 8 hours trying to find out where the issue would be and miserably failed. Below are certain logs and output that might help traingulate my issue.
Its a Dell Inspiron N4030, with Intel onboard graphics. I have the xf86-video-intel driver installed and the display works perfectly fine with laptops default display.

The tray loader iMac has no external display support
By design NO. However, for those of us with tray-loaders iMacs that have failed video boards, you can simply disconnect the internal video connector. This connector is essentially a "VGA" cable inside the iMac case, but it uses the old-style Apple video connector. It is a simple matter to buy an Apple-to-VGA adapter and connect it to the internal video output and connect that to a VGA cable leading to an external monitor.
The tray-loader's graphics hardware, when connected to an external display, recognizes this fact and automatically allows the higher resolutions up to 1600x1200. So I don't think the slot-loader's superior graphics hardware maxes out at 1024x768, but it is intentionally limited due to the need for the VGA output to mirror what is on the built-in display.
If you could internally disconnect the built-in display, perhaps the graphics hardware would recognize this fact and allow for the higher resolutions on an external display, as with the tray-loader iMacs.

How do I use my old iMac as a third display on my new MacBook pro?

I have both an iMac 2006 and a new 2011 MacBook Pro. I would like to use the old iMac as a second, prhaps third, monitor. How do I tturn my perfectly good iMac into a regular monitor?
Also, within my setup, I have an extra 19" vga display and a new Yiynova 19" interactive pen display. I would like to use my macbook pro as the main coputer and the rest as displays.
ppleas help.

Welcome to Apple Support Communities
If your iMac has got Mini-DVI, you have a 17, 20 or 24-inch iMac that doesn't support Target Display. Late 2009 and Mid 2010 27-inch iMacs, and iMacs with Thunderbolt can be used as external displays. Read > http://support.apple.com/kb/PH11302?viewlocale=en_US&locale=en_US
If your old iMac doesn't support Target Display mode, you can use ScreenRecycler to use your old iMac as an extended display for the new iMac. The only thing you need is that both Macs are connected to the same network

What cable do I need to connect my 27 inch iMac to my Cinema Display

What cable do I need to connect my 27 inch iMac to my Cinema Display to have two displays?

It depends on what type(s) of video input you have on your TV. If you've an open HDMI port on your TV, you can use a Thunderbolt (Mini DisplayPort) to HDMI adapter and it will carry the sound also. See -> here.
Good luck,

IMac with 24" Cinema Display

Yesterday I went to the Apple Store and asked about buying a new 27" iMac and connecting it to my 24" Cinema Display. I was told that I could do that with an adapter and was sold a Mini DisplayPort to DVI Adapter.
When I got home I realized that wasn't the correct adapter. I called the store and was told that it wasn't possible to connect the iMac to that particular monitor. (As an aside, I was really ****** because that was the whole reason for making this purchase!)
Then I realized that the video plug fit in the iMac video port. I plugged it in and it seems to be working just fine. I just don't have the power and USB plugs from the monitor cable plugged in.
So, am I okay doing this? Am I hurting anything? Was the genius at the Apple store wrong when I was told I couldn't connect the iMac and the Cinema display? The reason for my concern, several years ago I plugged an external display into an older iMac and it caused video problems requiring the replacement of the monitor.
I can't seem to easily find anything in the forums, so any response/reassurance would be much appreciated!!

OK, you confused me talking about the m-DP to DVI adapter. The Apple Store should refund your money for that bad recommendation. I think whomever sold it to you made the same mistake that I did. They thought that you had the model Cinema Display prior to the one that your have.
So you have the 24" Cinema Display that was available from 2008 until just this past summer. It has one cable that ends in three connectors; mag-safe, USB and m-DP. Well the mag-safe connector was to power a MacBook so that one is fine not plugged in. The USB connector is for connecting the USB ports on the back of the display to your Mac, so there should be no issues plugging that in because it will give you an extra self-power hub if you need more USB ports at some point. And of course the m-DP is allowing the Mac to drive the display.
I think that you should still be OK. Your iMac has a better GPU than the minimum requirement for your display.

How do I use my 2011 27" iMac as an external display for a pc?

I just bought a 27" imac for my home, and was also planning on using it as an external display for my work Dell Laptop running Windows 7.
The Dell laptop has a displayport output, so I was planning on getting a displayport <-> minidisplayport cable, and using the iMac in target display mode.
I would simply plug the minidisplay end of the cable into one of the iMac's 2 Thunderbolt ports. Seemed fairly simple.
Except now it seems from what I have been reading that 2011 iMacs DO NOT WORK in target display mode unless they are connected to another Thunderbolt source. This leads to me two questions.
1. Can anyone confirm or deny this? If this is true, does that mean I cannot plug my Dell's displayport into the iMac's Thunderbolt port as I described above?
2. If #1 is true, is there any other option? Are there any adapters that I can use to turn my Dell into a Thunderbolt source for display purposes?
If I can't resolve this I will have to return the iMac
Thanks very much.
David

David,
Sorry you can't use the 2011 iMac as an external display to your PC. The feature you are referring to is called Target Display Mode and works on 2009 & 2010 27" iMacs. The 2011 machines use Thunderbolt as you know however they do support external displays that are not Thunderbolt displays. So for example if you wanted 2 displays on the iMac you can easily do that with either Mini Display port to DVI or MDP to VGA or even HDMI. MDP is the same size as Thunderbolt and this will work fine to drive a display, TV or even a projector.
I'd recommend reading Apple's explanations at Target Display Mode 2009 & 2010 iMacs & Target Display Mode Mid 2011 iMacs.
Using a Mac as an external display for a Windows machine to me seems like a horrible waste of a Mac. Why not enjoy the iMac and if anything run Windows on it and get rid of the PC?

Can I use my old 2006 iMac as a second display for my new iMac?

Can I use my rusty old 2006 iMac as a second display for my new 2012 iMac? How do I keep one computer from trying to take over the other one? thank you.

Try ScreenRecycler, the 2006 does not support display input.

Is it possible to input itunes into DVI/HDCP input from imac with Apple mini display portS?

Is it possible to input itunes into DVI/HDCP input from imac with Apple mini display port? Or is there another way?

The problem with itunes is needing a computer running it. or continuous internet connection.
A Time Capsule is AC mains powered.. no battery. Although you can certainly buy an older Gen4 TC and modify it ...
https://sites.google.com/site/lapastenague/time-capsule-power-supply-repair-kits
I have run my TC on a 12V SLA battery.. which would neatly meet that part of the functionality you want. But it is heavy and not really the rugged sort of device I think you want.
But I would look at other media players and other ways of storing movies than iTunes.. if you want to carry the whole lot around with you .. A bunch of SD cards even you could plug into the ipad??
External storage for iPad?
A small cheap PC/Mac laptop with a 1TB hard disk in it.. and 11" or 13" screen.. can often be a much better solution than lugging around multiple items so you can fit Apple devices into your life.

IPhone 3G displaying emails in random order / not displaying some at all

My iPhone is displaying emails in random order - mainly oldest first at the moment. Since I can't set viewing preferences I would like to know how to get iPhone mail back to normal behaviour. For some reason it is not displaying emails from 5 December to 30 November as well.
I have deleted my .mac mail account and re-instated it to no avail.
I should add that my mac.com webmail is behaving similarly strangely. Instead of displaying emails by most recent first it decided to display them by oldest first.
Since I have not done anything differently and this behaviour came out of the blue I am pretty puzzled.
Mail.app on my Powerbook works fine btw.

First try Resetting it: Hold down the home and sleep button, ignore the red OFF slider, wait for the Apple logo then let go.
If that does not work, Restore your iPhone in iTunes from your backup.
If that still does not fix it, Restore your iPhone and a new phone (not from backup) and see how it works. If it is doing fine you have a app you are using that is probably causing your problem. Load them one and a time until the problems recur and you will have found the one that is a problem.

Facing "Display Flickering" problem with my 15" macbook pro(A1286)while swapping the desktops and closing the tabs.....need help...reply soon

Suggest Solution for this Display Flickering problem ....

Hi, I read the post about calibration and I probably do that a little too often TBH! As I get so little time out the battery and mainly use my MBP on my lap, usually with the power supply near by, it gets charged to full, run to empty to the point of sleep, or sometimes it even cuts out and then is recharged to full again, so I really think it's new battery time. I've seen non Apple Official ones for between £35 and £65 that have 3 year warranties and state they are around 5200mh but am unsure due to reviews.
Later...
Anyway's I have now ordered a non Apple replacement from Amazon for about £35 and it has several good reviews and 4.5 out of 5 stars so I'll see if it works and report back. If it doesn't I'll send it back and get the Official Apple one.

Why is Best for Display setting in new iMac with Retina 5K Display only 2560 x 1440?

I just saw the new iMac with 5K Retina Display. It's awesome! I do have one question, though: The default (Best for Display) resolution is 2560 x 1440. That is the same as my current LED Cinema Display. Adjusting the scale in the System Preferences/Display settings maxes out at 3200 x1800, not 5120 x 2880. I'm not sure why the highest scale option isn't the full resolution of the display. Can anyone explain this or direct me to an article that does?

That got my curiosity too. It's something about the retinas pixel density per inch being higher than other displays, such as a Cinema HD.
The "Best (Retina)" option says "Looks like 2560 x 1440" when you roll over it, but the real pixel density is actually doubled I think, so 5120 x 2880.
The "Looks like..." phrase seems to refer to the size of elements on the screen rather than actual pixels. Perhaps that's what some folks call virtual pixels.
