IMac display help

My IMac is about a month old and i recently tried to install a cd for one of my classes. As soon as i put in the cd, the display turned weird colors and blue and light blue. I tried restarting and turning it off, but nothing works. The only way i can see anything on it is if I turn the display settings to 256 colors, instead of millions or thousands. Any input on what you think is wrong would be greatly appreciated. Thanks

IMac - Display doesn´t work after restart

My iMac 21 Display doesn´t work after restart. If I turn it off and 1 hour later I want use it again the iMac shows the white screen with the mac logo and then the display goes off. I connected an external display to check if the iMac was ON and with the external display I can login and do everything but the iMac Display doesn´t work .
If I turn it off and wait 3 or 4 hours and then turn it back on the display works OK.
This is very strange behavior I have spent hours and hours trying to fine the solution or a similar issue but nothing so I am looking help here at apple.com
BTW When I bougth the iMac 21 there were some spots over the display so the display was replaced by the provider. The warranty has expired by now.

To tell you the truth, I don't know if they have to repalce the LCD panel or what they do for a bad backlight. In this reality of block or assembly replacement it probably involves repalcing the panel and not the backlight component. Don't know what it would cost. You'd have to ask that of a service center.

IMac display for a PC

Does anyone know how I can hook up a PC to my iMac display. I know by purchsing eyeTV you can hook media devices, but is there hardware available to hook up a PC through and A/B switch or something to the like?
Please Help, Thanks.

What you can do is to network the computers together and download Microsoft's free remote desktop for mac, which lets you open your pc as a window on the imac and control it from your mac keyboard.
The imac has no video in, though, so you can't use it as just a monitor for another computer, mac or pc, as Jürgen said.

Can't read iMac display

My imac display is unreadable. Everything looks pixelated and blurry with the resolution set to 1680X1050. It has the Radeon X1600. Tried font smoothing and changing the resolution but it didn't work. Also hooked up a second monitor and the image looked perfect on that one. When you zoom in on the imac its readable, but still does not look up to par. Any help would be greatly appreciated.

HI and Welcome to Apple Discussions...
Try Resetting the PRAM
If that doesn't make a difference, might be a good idea to run the Apple Hardware Test

IMac Display stretched and out of focus

My iMac display is not right. It is slightly enlarged and out of focus. I have already tried the display settings and holding the control key and scrolling down. I also tried restarting. Nothing is working. Last night I tried configuring my router for wireless. I supposedly made it secure with a password, which I had to use to connect to my network. The screen thing happened after that. This morning I checked the connection again and the little lock icon was no longer there. Could the two be related? Please help! I am obviously not very apt with computers, but I'm trying.

This resolved my issues:
Preferrences > Accessibility > Zoom
then, uncheck Zoom and uncheck Zoom follows keboard focus.
Wait a few minutes. You can rechec them again but it won't go back to the stretched and out of focus look. I don't know why.

IMac displays only black & white

I set some wrong parameter and my iMac display switched from color to black & white. I cannot figure out how to change it back to a color display. Please help.

The tip above led me to the fix needed.
I unchecked 'Use grayscale' in
System Preferences > Accessibility > Display .
Thanks a lot for your prompt guidance.

I5 27" imac display doesn't turn on

Hi,
This issue just cropped up for me this morning. When I go to turn on my recently purchased (Feb 2011) core i5 27" iMac, the screen doesn't turn on. Instead, it remains black until I hit the power button again, after which it will usually come to life. It sometimes goes black again without any warning. I can usually get the screen to come back to life if I hit the power button. However, I have an older 24" cinema display hooked up as a second monitor, and it always comes to life when I start up, and never goes black like the iMac display. Anyone else having this problem? Are there any known/recommended solutions?
Thanks!

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.

Removing a sticker from iMac display

I work at a school, and one of our students thought it would be funny to put a not so small sticker on an iMac display. One of the teachers tried to peel it off, but there's still a lot of the sticker stuck on the glass.
I called Apple support about removing it, and they recommended iClear or contact solution. I was wondering if anyone had any other suggestions/hints about how to best remove the sticker.
It's a 20 inch iMac that was purchased around 2008 running 10.5.8.
Thanks!

HI,
Got the Remote?
Help to eject SL disk with a Remote.
Does your iMac have a Front Row Remote? If it does, you can use that to eject the SL disc when you restart the computer.
Try these steps to eject the cd if you have the remote.
Holding down the Menu button on the remote while starting up an Intel Macintosh enters the Startup Manager (same as holding the Option key at startup). The remote can then be used to cycle through all bootable partitions and can then confirm them by pressing the Play/Pause button. This can be especially useful for Boot Camp users who might frequently use this feature to boot into Windows partitions on the Intel Macs. The remote can also eject CDs or DVDs in this menu by selecting the disc and then pressing the + (Volume Up) button on the remote.
i put in my OS X system disk
The install disc(s) that come with Macs are "machine specific" meaning they cannot be used on another Mac.

Imac display problem, the resolution seems to be unusual, top bar and all folders on the desktop background is off the screen

Quit the game and restart the iPad.
To quit the game - Go to the home screen first by tapping the home button. Quit/close open apps by double tapping the home button and the task bar will appear with all of you recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner to close the apps. Restart the iPad. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
If that doesn't work try this.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

Putting iMac display to sleep, when using TV as a screen.

I have just connected my iMac to my 42" Panasonic 1080p TV, the connection was easy and is working fine. My questions relates to putting the iMac display to sleep when using the TV as a monitor, if I am watching You Tube, Sky Player or a DVD, I intend to use my TV as the monitor. Is it possible for the iMac to puts its display to sleep, whilst leaving the TV on. I played around with this today, however was unable to manage this.
Regards Craig

Hi Craig
There is no way to independently sleep either the iMac's Display or an attached Display/TV. However if in the Display Arrangement Preferences you set the attached Display or TV to be the Main Display and turn Mirroring Off, then FrontRow and the Full Screen Mode app's like, DVD player, QuickTimePlayer, etc. will black out the unused iMac display.

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.

My 20" 2.16 GHz Intel Core 2 Duo had become almost useless due to freezes and crashes- with NO crash reports in the logs.
They were often preceeded by video glitches, so I assumed it was a bad video card- unfortunately soldered to mother board.
Apparently, from forum postings, this is not an uncommon problem. The computer would run longer if the day was cooler, but rarely more than 10 minutes, so I suspected it was aggravated by heat.
Then I found this post from Bodomann on an Apple Support forum:
"Following up on my previous posting regarding my son's late model 2006 iMac that required a $900 logic board replacement:
Turns out the problem is apparently related to a bad CPU temp sensor. I installed 'iMac Fan Control' (Google it) which reported the CPU temp always at 32 degrees Fahrenheit (obviously incorrect). The same software allowed me to adjust the CPU fan manually. After multiple trials I set the CPU speed to 2800RPM after which the system would run forever - never freezing with the dreaded grey box 'reboot me' screen. I tried several times reverting the software to default speeds and the system would always crash within 10 minutes. "
I downloaded free Fan Control 1.2 for Imac from Derman Enterprises (they have an Intel iMac and a Mac Book/Pro version). It installs as a system preferences control panel. I cranked up all three fan speeds. The fans sped up noticeably. Horizontal lines have gone from screen (so far), no color artifacts and no crashes yet. I may have a real computer back! Hope Apple checks this out-
The control panel also gives the temps sensors are reporting at the CPU, hard drive and DVD drive. The CPU sensor reports the CPU temp as 32 degrees F- which is clearly wrong, unless Apple has been installing little refrigerators inside.
So thanks to Bodomann for posting- Hats off and three cheers to Derman and Cristoph for source code.
