IMac Screen Dirt?

Hello!
I just got the Late 2012 iMac 27 inch. And I noticed a black dot in the middle of the screen. At first I thought it was a dead pixel... until I took a photo of it and zoomed in. It looks like some sort of dirt stuck in between pixels behind the glass. Does anyone know what it is?

Sadly a common problem...

My imac screen has dirt spots

Hello,
I just noticed that my 27' iMac screen has some dirts from inside the glass. looks like humidity. It is increasing day after day.
Hardware less than one year and still under warranty.
Any idea what to do?
Thank you
Karim

My iMac also had this issue. I brought it to a repair shop and they were able to seal it for me. I think it only cost around $75. Haven't had the issue since I had it treated. They said it was condensation and that it happened quite a bit with various iMacs.

My ipad recognizes my home network but will not connect to the internet. When I click on AirPort/preferences at the top of the imac screen it says..."AirPort has a self-assigned ip address and may not connect to the internet".How can I change ip address?

Ipad will connect no problem to other networks.

First thing you need I think is to get your iMac connected to the Internet.
Shut down your iMac and you iPad. Then power off your router. Wait 30 seconds and power up the router.
After the router indicates that it is connected to the Internet then start up your iMac and see if it connects. If the iMac connects to the Internet then your iPad should too.
If this power up sequence doesn't work you'll have to dig into the router setup to make sure it is working properly.

How do i connect my iMac Screen to Apple TV?

I have read i can connect my iMac Screen to my Apple TV via Airplay.
How do i do that?
I have Mac OS X Version 10.7.4
I have the OS X Lion ready to download and install, but can't back up my computer (no where to back it up to :/)

Welcome to the Apple Community.
OSX 10.7.4 is Lion
Lion doesn't support AirPlay of the Macs screen to the Apple TV.

I have a Thunderbolt iMac 27" with a Thunderbolt Display attached. I would like to use the iMac and Thunderbolt display in Target Display Mode for my new Thunderbolt MacBook Pro. So far, it seems I can only use the iMac screen itself. How do I do this?

When I press the Command + F2, the iMac screen becomes a secondary for the MacBook Pro, and the Thunderbolt Display becomes the primary screen for the iMac. I was hoping that both screens would become secondaries for the MacBook Pro. Does anyone know how I should proceed? I have tried to connect the Thunderbolt display directly to the MacBook Pro, and the iMac to the Thunderbolt Display via the separate Thunderbolt cable, but there was no difference. And since the MacBook Pro only has the one Thunderbolt port, I'm not sure how to proceed.

Yes, eww, the language definitely states two thunderbolt displays, but I can understand the confusion and was siding with how they could make the mistake to think it would work like they want it to. My appologies for not being clear on that point, but I think you make it clear that the language in the ad says nothing about an imac.
Having said that all the language about TB would suggest that this would be possible. http://www.apple.com/thunderbolt/
High performance on display.
Thunderbolt I/O technology provides native support for the Apple Thunderbolt Display and Mini DisplayPort displays. It also supports DisplayPort, DVI, HDMI, and VGA displays through the use of existing adapters. So you can connect your Apple LED Cinema Display or other display, along with multiple high-speed devices, all from a single port.

Any external monitors as good as imac screen for text?

hi all.
this is my first mac. it's a new 21.5inch imac with a 2.7ghz i5 proc running OS X 10.7.3 and 12 Gigs of RAM (8 Gigs from crucial for $50, who can resist?)
i've got it hooked up to an external samsung syncmaster B2330 running in 1920x1080, which is this monitor's native resolution. works fine. it's hooked up via the dvi port on the screen via the mini-displayport to dvi adapter for the mac. i switch this monitor to the vga port when i want to use it as my pc monitor also running at 1920x1080. there is a source button on the monitor. very convenient.
the issue is that they text on this screen when coming from the mac is not as clear was when coming from the pc despite the fact that the vga port provides much less bandwidth than the dvi port the mac uses. i've read that the mac and the pc display text on screen using different methods. my pc uses an nvidia display graphics card. i believe mac use ati based hardware.
there appears to be much more interpolation when displaying text from the mac. perhaps this is a text size issue i'm not sure. either way i read a lot on this monitor and need it to be as good as possible for that purpose.
so the question is, does anyone have experience with an external monitor that is as good as the imac screen for text display. i can't use the thuderbolt display or a cinema display since they don't switch to different ports allowing my to use a single external monitor for two machines. i'm willing to spend up if there is a reason to do so. i'm on these computers a lot. i work from home with some regularity and my job is all about reading.
any help is appreciated.
best, c

External Monitor with iTunes - iMac screen goes black

I have an iMac with iTunes 7.7/Leopard and an external VGA monitor (I use the standard Apple mini-DVI to VGA converter) then I use the external monitor to watch video from my iTunes library.
All works well - I have my desktop spread over both monitors, I fire up a movie from iTunes, move the video window across to the external monitor and everything is good - I can watch the video on the external monitor whilst continuing to work on my Mac - the iMac screen displays the Mac desktop as normal.
However, if I put the movie into fullscreen mode (view -> fullscreen on the iTunes menu), the external monitor displays the movie in fullscreen mode as it should, however the iMac monitor goes black.
The only way to fix this is to exit fullscreen mode and go back to one of the view options (rg fit to screen).
Any ideas how I can have my external monitor in fullscreen mode and have my desktop back?
Many thanks
SM

How to i fix a flicker on my iMac screen?

My imac screen has just started flickering. I have researched it and it already a promblem with other mac's. How is this problem fixed? Thanks

You could reset the pram and smc to see if that helps. I would however suggest if the machine is within waranty you contact your local Apple store as this sounds like a hardware fault to be honest.

How to keep iMac screen black while keeping secondary monitor running for visual experiments in Matlab

Hi,
I'm trying to run a visual experiment using PsychToolbox in Matlab.
I've attached a secondary monitor to my iMac for this purpose and I'm having difficulties trying to
'black out' the iMac screen.
I need the secondary monitor to run at a refresh rate of 120Hz and at linearised luminance (did this for my secondary monitor),
so I can't really use my iMac screen. However, i need my iMac screen to be darken out because I'm doing a vision experiment.
I tried dimming my iMac screen but it doesn't go completely dark. I tried Ctrl+Shift+Eject (or was it Command) but it will darken both
monitors. I also tried mirroring, but it doesn't seem to work too.
I'm really stuck and any ideas will be greatly appreciated!
shui
NB:I'm using OS X Version 10.8.3.

I do not know the details of your experiment, but creating a black monitor is not difficult. For example a completely black page, e.g. in Power Point, set to fill the screen?
The advantage of doing this with PP is that you can move in to or out of the black page with just the space bar. You can set up your monitors so PP is displayed on just one monitor.

24" iMac screen mist behind glass

For a couple of months now my 24" iMac screen keep misting up behind the glass around 30 mins after booting - anyone know a resolution for this? Will Apple replace the screen even though i've had it around 4/5 years now?

It is common to get condensation between the display and front glass panel, if it is humidity and cool in your office or home.
A few things that you might try, are
1. Reduce the level humidity with a dehumidifier.
2. Leave the iMac on longer until the condensation dissipates.
3. Remove the front panel yourself and clean between the display and glass.
Will Apple replace the screen even though i've had it around 4/5 years now?
No, but if you contact your local Apple Store or AASP you can schedule an appointment to have it dried and cleaned.

IMac Screen Failure

Hey,
I was just wondering if any of you are experiencing screen failures as noted in the link below? If so, is it the aluminum iMacs, or is it the white ones?

Thanks!!

Hi autiger
Which iMac do you have and are you having any display issues?
I don't believe it can be jinxed, so I'll do a little bragging here. My 17" Early Core Duo w/Apple Care purchased Jan. 21 2006 is great and has no gradient light/dark, no dead pixels and only a very very small backlight bleed. The sRGB and Adobe RGB (1998) profiles were OK, but the display seamed a little washed out. After more than a few tries, and some good advice from Barbara B and others here I was able to set a new profile that is much richer than any of the factory supplied profiles.
All display manufactures and computer system will have there share of issues, some more that others. I have had more than a few Apple's over the last 20+ years without a single hardware problem. I do have to admit though, that with the all-in-one Intel I bought Apple Care for the first time ever???

24" 2008 iMac screen going black

My 24" 2008 iMac screen keeps going black then coming back after a while. What temperature would it need to get to in order to knock out the display? I have iStat.
Also, if the screen fails due to graphics card or other component, is it possible to connect an external display to use it until I can upgrade to a mini?
Cheers.

As old as your iMac is, have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...
You are now in a perfect position to do a
SMC RESET
http://support.apple.com/kb/HT3964
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
It is the 5 second timing that initiates the reset.

Would like to record what's on my 24" iMac screen. How?

I would like to record video of exactly what's appearing on my 2008, 24" iMac screen. I would like to have the video saved directly onto my hard drive. I also have usb and firewire external drives available. Any suggestions on how to do this? And instructions please?
Thanks in advance!

Open your quicktime application. Under the file menu there are 3 choices pick new screen recording and have fun capturing screen recordings that you can make into training videos or just for your collection.
If you want to capture a picture of the screen hold the shift+command keys together and then hit number 3 to capture the whole screen and the same thing but hit number 4 to make a selection and capture just the selection.
Good luck and have fun.
Rick...
