Apple imac display dirt or missing pixel in screen

hi i have just today received my new silver imac. I bought it off the refurb site on apple but it appears to have a black spec mark in the screen about 5 pixels big. I have seen missing pixels but this appears to be a random shape which makes me think it cud be dirt in the screen. my question is does anyone know where i stand with apple do i have to except this or will they sort it?

Hopefully all that you need is to perform disk repair (not permissions) using the Disk Utility version located on your grey-label Install Disc 1, once you have booted from that disc.
Insert the disc into your optical drive and immediately choose "Restart" from your blue apple menu. Upon hearing the startup chord, immediately press and hold the "c" key until you see the progress indicator. First install screen is language selection, second install screen at the top of the display you see pull-downs, one of which is Utilities. Select Disk Utility, from the drives listed on the left, choose the entire internal hard drive which should be the first listed. On the right verify you're on First Aid panel, then click "Repair Disk" button and allow to run until completion. Re-run if necessary until it reports "No repairs necessary"
Quit Disk Utility, Quit installation sequence, restart to usual startup disk.
Please note that your HDD is now over 80 percent full, and many believe that beyond that point you might start to see the iMac's operating efficiency steadily deteriorate. [click the iMac G5 link, search "swap space" or "defrag"] You might want to consider adding an external firewire/usb hard drive for additional storage, but certainly get something for backing up. There is probably a little on your current HDD that you would rather not lose:) This is the time to protect yourself.

Imac 27 inch with additional Apple Thunderbolt Display (27-inch)

Hi there,
Recently I bought a 27 inch iMac. I want to connect my Apple Thunderbolt Display (27-inch) as a second screen.
The iMac has 2 thunderbolt ports. Attaching the Thunderbolt Display has no effect, the screen keeps black.
If I attach my Macbook Air it directly shows a second screen for my Air (so the screen is fine).
How can I enable the second screen for my iMac ?
Love to here.
Walter

Try Command + F2
You should be able to make it work from there

Can I use an Apple Cinema Display as a second monitor for my iMac?

I have a new 24" intel iMac and was wondering if I could use my old 20" Apple Cinema Display (aluminum) as a dual display. What cables do I need?

Just had a good look inside my box and nothing. Maybe it's a Apple UK thing
The back of my iMac does have a Mini DVI port so I'm gonna pop down the Apple store tomorrow morning to pick one up.
Thanks for the advice, I'll let you know if I'm successful.

How to connect a apple cinema display to an imac

I have a brand new 27 inch iMac. I also own a 30 inch Apple Cinema Display. What peripheral adaptor do I need to connect the display to my new iMac?

Hello,
Thunderbolt/Mini DisplayPort-> Dual Link DVi cable...
http://store.apple.com/us/product/MB571Z/A/mini-displayport-to-dual-link-dvi-ada pter
A notable peculiarity of Thunderbolt is that it uses exactly the same connector as Mini Display Port, and that's not all. The Thunderbolt connector also carries Mini Display Port video signals. That means you can plug a Mini Display Port video cable/adapter in to a Thunderbolt connector and your monitor will work.

Can I use a 30" Apple Cinema display with a new 27" iMac?

I have a brand new iMac(27-inch, Late 2013), OS X Mountain Lion (10.8), i7 3.5 GHz, 32MB RAM, 4GB NVIDIA. I will soon be upgrading it to Mavericks, if that makes a difference. My understanding is that the resolution on it is 2560 x 1440.
I'm looking at buying a used 30" Apple Cinema display. I'd like to use it with my new iMac. The only advantage for me would be that the 30" screen is larger and things on it easier to see (or so I'm guessing).
I need to know if the 30" Cinema display would work with my new iMac, and if it would, as I'm guessing, give me a larger, easier-to-see screen.
I currently have my new iMac connected to my old mid-2010 iMac as a target display (that old iMac has a minidisplay port--no Thunderbolt), and that works great. I just want a larger screen.
I called Apple support, and the tech rep wasn't sure it would work. He seemed to think that the 30" Cinema displays were made with different connections. Some had minidisplay ports (which he thought would work), and some a cord built into them that provided some other type of connection (that I guess would not work as far as he knew).
Can anyone tell me if this would work? Would my new iMac and its video card support the 30" Cinema display? Would the result be as sharp and good-looking as my iMac's built-in 27" display, but only bigger (which is what I'm hoping for)? Any advice is appreciated.
I don't yet know many of the specifics of the 30" Cinema display I'm considering. I know it is about 3 years old. And here is a picture of the back of it:

Yes, you should be able use the 30" Cinema Display with your new iMac without problems. You'll need a mini-DisplayPort to Dual-Link DVI adapter:

I haven't had the 30" myself to test so I don't know if there any caveats. Perhaps someone else here will have personal experience.
Regards.

When streaming a movie from an imac to apple tv, is there a way of putting the imac display off? I find it a waste having the screen on in another room. Any advice?

No problem.
This is a user forum so you are not addressing Apple. There's nothing to fix, that's how home-sharing works. There would be no way for the ATV to recognize your library and display content if the computer is in sleep mode.
You can always airplay from an IOS device or use icloud if you don't wish to keep the computer on.

Is it possible to connect both a Wacom 24in. Cintinq AND a 30 in. Apple Cinema Display to any of the current line of iMacs?

I currently have a Wacom 24HD Cintiq and a 30 in. Apple Cinema Display hooked up to an old '06 Mac Pro. I'd like to purchase a new iMac to replace the Pro. Is it possible to attach the Cintiq and Cinema Display to it?

Hello, it depends what kind of inputs those Monitors have, but if I see them correctly...
30" needs this...

That means you can plug a Mini Display Port video cable/adapter in to a Thunderbolt connector and your monitor will work.
If you plan to do other things with your Thunderbolt connector and don't want it wasted on a monitor, you can also choose an HDMI --> DVI adapter, which for your purposes will be functionally equivalent.
You can even use both at the same time.

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.

I have bought a Apple iMac with Retina 5K display! Can I use it with all my Adobe Creative Cloud

I have bought a Apple iMac with Retina 5K display yesterday! But today I read something negative about this Imac regarding to to Adobe Creative Cloud, - so I would ask if I can use this iMac with Retina 5K with all my Adobe Creative Cloud programs??
I have not unpack it yet, so I would be happy if you could tell me if I should keep it or exchange another Mac if this iMac with Retina 5K display does not work OK in Adobe Creative Cloud. I mostly use the programs Photoshop, Illustrator, InDesign, and Muse.
I look forward to hearing from you!

WOW!!
That was great to hear.
I have just read this tread: https://forums.adobe.com/thread/1626784?start=0&tstart=0
So therefore I was worry about Illustrator which I use most of all programs.
Thank you !!

IMac display jumps 1 pixel left and right

Has anyone ever heard of this before, it seems crazy to me.
My iMac display started acting up two days ago.
When the cursor crosses the screen from side to side, the screen jumps 1 pixel to one side!
Specifically, moving the cursor from left to right, the screen jumps 1 pixel left (as if it is panning over to that side) and and the reverse for the reverse direction.
The 'extra' column of pixels appears normal (ie not simply black).
The picture is a little fuzzy.
At lower resolutions, the screen looks terribly fuzzy like the anti-aliasing has become overactive (maybe this is a known issue for this video card) but doesn't jump.
I've repaired permissions, rebuilt things, etc (using Onyx and also applejack) but no change.
After my previous mac died prematurely I was sure to get Applecare for this iMac and need to take it back anyway (the dvd-burner has predictably failed) but I I was surprised I'd never heard of my pixel jumping problem before.

More than likely somehow 'Zoom' got turned on.
To disable Zoom, open System Preferences->Universal Access preference pane and disable Zoom.

I called Apple about the 20" iMac display problem today...

I have the same display problem that I've been reading about here, it's much much brighter on the bottom of my screen than on the top and viewing the screen from an angle makes the screen look very dusty and dirty.
First I talked to technical support and because I live 75 miles from an Apple store, he said a technician would come and look at it tomorrow even though I said it was a problem that is very common and just not on my computer. It will be interesting to see what the technician says.
Then I called customer relations to put in a formal complaint against the 20" iMac screens. I told the man that even on the Apple support forums here that everyone was complaining about it. He said everyone where he worked was using 20" iMacs and as he looked at the screens next to him, he noticed that the colors were all off, looking dirty brown like mine. He said that's just how the new 20" screens were. I tried my best to tell him that it just wasn't right that the screens were so flawed and, although he kind enough and understanding, he didn't see any big problem with them.
He did submit my formal complaint at the end but I have to tell you all, it sure looks like Apple does not see any problem with these screens. He suggested that I write to Apple at their corporate office to let them know of these problems. Here is that address:
Apple
1 Infinite Loop
Cupertino, CA 95014
So that's my next step, writing to the corporate office.
I'll update this post after the technician comes tomorrow. I really don't expect this to be fixed but I shall let everyone know.

I have been watching this forum for months and have come to a conclusion that Apple
has taken the "easy road" by using cheaper components as evidenced by these discussions pertaining to cheap lcd computer screens. Also, with the Imac there is limited upgrade paths and the fact now
the imac has become more of a glorified computer with the internals of a laptop which suggests it is almost mandatory to pay extra for apple care for 3 year warranty because of uncertainty for longevity in my opinion. I am still using an apple 2002 quicksilver G-4 computer almost 6 years old that has not given me and problem. I have also been able to upgrade the hard drive, dvd rom drive myself-you cannot readily do with the current imacs. I was thinking about replacing my G-4 with an Imac, but have now come to the conclusion that Apple is losing focus with providing quality products and unless something drastic happens which I doubt, Apple will lose me as a future customer. I may be forced to go to the other side and buy a PC.

Apple iMac "Core 2 Duo" 2.66 20-Inch (Early 2009) display problems

I have a Apple iMac "Core 2 Duo" 2.66 20-Inch (Early 2009) whose screen has gone partially black to be more specific the bottom half of the screen, the screen is split almost in half the top half working fine and the bottom half completely black. The screen does not appear to be crack. Screen went half black while on itunes one day and has been that way ever since, any idea what it could be? (if you go to my profile a picture of the screen is provided)

Thanks for the response, I just installed Snow leopard (10.6.8) but the issue is when I go to the apple store and tried to download Yosemite, I don't see the option to download it. Looked around everywhere and no luck. What I'm doing wrong? I tried also the software update and I just get to the page where says no updates available and shows Yosemite as a free upgrade but when I click on the button nothing happens.
Any help would be really appreciated.

Intel imac display glitch and involuntary restart

Just want to know if anyone else has experienced this specific problem, there are plenty of complaints about intel imac displays but I can't be bothered to sift through them all trying to find a match for my problem.
A couple of months ago I was watching a video in quicktime and noticed that my screen was glitching and flashing fragmented diagonal lines - like a commodore 64 loading type thing. Then the spinning-ball came up and a force quit didn't do anything so I had to force shut down. I started up and it occured again. Then the screen went blank/black, but still lit up, and restarted without me doing anything. It also got stuck during start up the second time this occured. I panicked and ran out to buy a 500GB external drive, backed up all of my work and then re-installed mac osx from disk, archive and install job. This seemed to sort it and for the following two months it seemed OK. No sign of any problems.
Since then I have updated from 10.4.7 to 10.4.10 (which I have suspicion that it screwed the firmware in my motu 828 firewire audio interface, costing me a £130 repair - but that's another painful story).
It happened again tonight (the screen thing, not the motu). And the ball came up and I couldn't do anything. Force shut down, restart - screen glitching again. Then I had 2 unexpected restarts, one getting stuck in startup. Then a successful startup but accompanied by the glitchy graphics, mainly red/pink pixellated diagonal lines flickering in and out. I ran a disk first aid - no problems. Did a disk permission repair. Shut down and ran a hardware test, the first few minutes of the test the screen was still at it but then stopped glitching, hardware test found no errors (it was an extended test too). Now I'm back on it and it's all OK.
Any suggestions/similar stories?
When it occured 2 months ago I had the original ram that came with the imac. Now I have 2x1GB sticks of crucial ram.

That's it! Well, that's what I have. Unfortunately, I don't know about the cause, but I don't ever recall having it prior to an update going back about a year ago. I recall an update, and that update being immediately followed by some sort of Apple Graphics something-or-other. I feel pretty certain that's when I first noticed this. I just had my LCD replaced for another reason, but I think you'll agree, it's not an LCD issue. In my case, browser activity, scrolling up or down in a page, seems to be the most common trigger. I've also seen "pieces" of the torn page, on the screen when minimizing the browser to the dock (usually Firefox, but I think I've seen it with Opera and Safari too). Is there a way to find update packages installed somewhere? I'd know it if I saw it, and I'd definitely try removing that suspect package/update.

How Can I Test New Apple Cinema Display?

My new 30" Apple Cinema Display arrived today but the arrival of my MacBook Pro is still 4 weeks out (I ordered both at the same time for dual warranty purposes). I cannot hook this ACD to my wife's 12" PB and the only other computer that may have the ability is my daughter's new iMac Intel Core Duo (but I'm not sure if it will power the 30" ACD). I would like to test for stuck or dead pixels. Can I plug the AC cord into an outlet and no video connection then power on or will this show no pixel anomolies, or worse, cause potential harm to my display? Anyone? Thanks to all that may reply.
PS: I threatened to cancel my order unless the Supervisor allowed me time to evaluate the new monitor the full 2 weeks AFTER the arrival of my MacBook Pro, so I have plenty of time, just no computer to run the darn thing!
PowerBook G4 12" aluminum & iMac Intel Core Duo Mac OS X (10.4.5) Apple 30" Cinema Display w/ iLift LCD monitor arm

I think pretty much any Mac with DVI will drive the 30" ACD, just not at the native resolution. You will get 1280x800. But if you are just looking at a solid full screen of a single color, for the purpose of trying to spot dead/stuck pixles, the low res shouldn't make any difference at all for such purposes.
