Ghost display problems

I have an apple 20" display which functions normally, but for some reason the computer seems to think that there is an extra VGA display -- it appears under system preferences / display. When I do gather windows, two windows appear: VGA and color LCD. Under arrangment there are clearly 2 blue rectangles, but I DEFINITELY have only 1 display!
HELP PLEASE!
Thanks,
A
Here's the system 411:
Displays:
Color LCD:
Resolution: 1680 x 1050
Depth: 32-bit Color
Core Image: Supported
Main Display: Yes
Mirror: Off
Online: Yes
Quartz Extreme: Supported
Rotation: Supported
VGA Display:
Resolution: 640 x 480 @ 75 Hz
Depth: 32-bit Color
Core Image: Supported
Mirror: Off
Online: Yes
Quartz Extreme: Supported
Rotation: Supported

Try this:
Open Spotlight and seach for "windowserver". Spotlight should find a file that looks like com.apple.windowserver.xxxxxxxx.plist where the xxxxx is a string of numbers and letters. Likely two such files will be found. Throw them in the trash and restart.
The .plist file will get automatically regenerated for the 20" display and hopefully that is all. If this doesn't clear the problem and a second .plist file gets regenerated along with the one for the 20", then there may be a hardware problem with the graphics board.
By the way, you will lose any color calibration or other preferences settings you may have had for your 20" ACD in which case you will have to redo them.

IMac ghost display problems (and apple technicians weren't able to solve)

Hi,
So my problem here is quite weird. I tried researching the forum for something like this, but nothing really came close to whats happening to my iMac.
I have an Intel-Based iMac, 24 inch screen.
I bought it on 2008. Since late 2008/early 2009, i had these weird "letters" underneath all my pictures. I work with photography/video editing, so this was very annoying, yet i kept ignoring, since the rest was working fine.
Then slowly the iMac ran slower, more sluggish-y. Like if all life was sucked out of it, sort of description.
Then, 2 months ago, there was a total failure of the HD. I was lucky to be able to back up all, before it didnt let me even enter the computer. It would just think for hours.
I brought it to the technical support near to my home, and i also told them about those weird "letters" on the left side of my screen. They said it was due to my hard disk, and i was, ok...since the hard disk had a failure.
They did a check up, and yep, the hard disk was k.o, evidently. They replaced the hard disk, and told me all was fine.
It did "seem" fine for the first couple days. No more running slow, no weird letters that would distort my pictures (for example, i could see my iTunes music list underneath a picture i was working on photoshop, or a video i was displaying!).
After a couple of days...same story started again. The left side of the screen was flooded by all underneath (open windows, the desktop icons, the texts i had open on safari, basically anything would appear translucently underneath any image or video i would open). Then, flash player would crash every 3 videos, blank cd's would get automatically ejected so i couldnt burn any cd, computer would run slow etc... etc...
So i cleaned up my computer, did a back up, erased all, and ready to bring it up to technical support again. And misteriously, all symptoms disappeared. So i explained to them what happened, and they said probably it was the graphic card.
I thought finally my problem was solved.
24 hrs later, i got an email that my computer was fixed. That it was only a hard disk "permits" issue, and they solved it.
I have had the computer for 3 days, and the screen problem is starting again, and now the permits are perfectly fine in my computer, and nothing comes out as wrong in the diagnostics tool!!!!
I didnt even work with the computer, but now i can see my itunes list through the safari window, as grey letters....kinda 3D, popping out. Its very weird. And i cant capture it because when i take a screen capture, it all appears fine.
Left side of screen is the affected. And no, its not a condensation issue.
Also, i can see some lines when i start up the computer. On the grey screen portion of the start up.
I dont know what it can be anymore. I know this is a long post, but i had to explain all what happened to it.
Any help would be great.
Thanks

You might want to clean up your profile. An iMac G5 will not run Mac OS X 10.6.4!
My experience with things appearing on screen but not in a screen capture is that it is on the display itself and not involving the GPU.
I think that you have image persistence, similar to CRT burn in. It is caused by having the same image appear in the same location over long periods of time, like a Safari window always in the same location, or an iTunes window, etc. The pixels get stuck showing that image.
There are different little apps that folks have developed to get the pixels unstuck. Google LCD image persistence and you can find a number of them.
Here is one suggestion;

IMac to TV (HDMI) : Ghost display when TV is off

Hi,
I'm using my Sony TV (40BX420) as my secondary display for my iMac 27", connected via
MiniDisplay Adapter+HDMI Cable.   When connected everything works fine, the
audio & picture appears normally. I use this setup to watch movies on my bigger screen.
I always keep the hdmi cables physically connected between the TV & iMac (which is always on).
The problem is when I switch the input on the TV from HMDI to Antenna (to see the TV channels), the
hdmi appears active to my iMac, and the audio & windows which was getting displayed on the TV, does
not reappear on my iMac.
The only solution to my problem is to physically disconnected the hdmi cable when I do
not want to watch the computer content on the TV.
I'd an older Toshiba TV, when I connect the same hdmi cable to this tv. As soon as I change the input
on the TV to HDMI, the iMac responds, with activating dual monitor, when the change the input, or switch
the TV off (standby) the imac goes back to single display mode.
I call sony, their tech support is horrible, they told me it a feature of their TV, it keep the HDMI active in standby mode.
I tested this buy shutting down the power on the TV, but the iMac was still behaving as if connected and I've a ghost display
on the TV.
Please let me how can I solve this issue.   They may quite a few of you who is connecting their iMac to TV
Sajid

hi there,
have you solve this problem?
Because I have had this issue also, still looking for the solution.
Thanks

Ghost Display: 'Generic non-PNP Display'

Before I start talking about the problem I have Thinkpad T420s 4173-W1J (which has Intel HD + NVS4200) and I have never used it with any external displays prior to this issue:
A while ago I noticed a strange problem. If I let the computer enter sleep mode by itself (due to inactivity) and then woke it up, the built in display would be turned off and I had to use Fn+F7 and kind of work my way, blindly, to the right display output.
I figured this was because the Thinkpad thought there was a secondary display and sure enough the Device Manager and the screen-res settings in windows showed a 'Generic non-PNP Display'. I started to look around on the web for solutions as I wanted to bring this to an end asap.
-I started to uninstall drivers then reinstalling drivers. It didn't work!
-I tried uninstaling drivers, then installing the video drivers from Intel and Nvidia support sites. It didn't work!
Then I started to look at the hardware side of things...
-I plugged in my external display to the VGA and as I did so it replaced the non-PNP with PNP. I figured that there was something wrong with VGA port or one of the GPUs. This would probably suggest that the hardware thinks theres a display connected when there isn't. As such it cannot detect which display it is i.e. non-PNP. Then when I plug in an external display it finds a display on that same port, replacing the non-PNP display status.
-I read that this non-PNP phenomenon could be due to dust in the VGA. So I vacuumed it. It didn't help!
-I also read it could be due to electrical load on the port due to a faulty graphics unit. For this I need to send it in to get it fixed, but I did not give up yet...
-Lastly I heard it could be due to electricity caught up in one of the capacitators that the output used (or something like that). This was a thread about a similiar problem for a desktop and it was suggested that the person in the thread should disconnect his LCD from the PC and unplugg the powercords and let it rest for 5-10 min. I was desperate for a solution to my problem and so I figured I'd try something as similiar to this. I unplugged the power cord to my Thinkpad, removed the battery and waited 10 minutes. Sure enough when I booted up the 'Generic non-PNP Display' was gone!
I thought I had fixed it! I checked the Device manager several times that day and there was no ghost display visible. However, as I booted my Thinkpad the next morning, it was back... removing the battery and waiting 5 minutes fixes the issue as it did before. This is not a solution to the problem. I cannot remove the battery each night only to reseat it the next morning. Then I would never be able to use sleep mode.
I guess I should use my warranty to get my T420s fixed since I without doubt think this is a hardware issue. Does anyone have any other suggestions?
T420s 4173-W1J
i5-2520M // 8GB RAM // Intel 320s 160GB SSD // 1GB Nvidia N12P-NS2 // Intel 802.11agn // Bluetooth // 1Gb Ethernet // UltraNav Secure Chip // Fingerprint reader // Camera // Win7 Pro 64

I am too fond of my Samsung display so I wouldn't give up after you explained to me that I basically could end up with any of the other displays if I issued a repair.
So I kept on trying and figured out the following...
-Shutting down the computer, removing the battery, putting it back in a second later and booting 'fixes' the issue for the time being.
-Restarting the computer after the above is done, does not make the problem re-appear.
-However, shutting down the computer and booting it a second later does make the problem re-appear.
Now I know how to 'artificially' remove the problem and how to make it re-appear, which is good for testing purposes.
The following tests were made after making sure that the problem was existant in the previous boot...
-Booting with a VGA monitor connected finds the display (as it should). When disconnecting the monitor in windows it is not visible in anymore (as it should be). The ghost display does not appear in its place so this 'fixes' the problem until the Thinkpad is shut down and then started up again (without the monitor), at which point the problem has re-appeared.
-Entering any BIOS menu (F1, F8) before bootup without doing anything or changing any settings 'fixes' the problem until the next boot.
Strangely enough, what ended up fixing this permanently (won't know for sure until tomorrow morning) was a combination of doing the following...
-I pressed the Thinkvantage button. Went to the windows settings and pressed repair windows. After the files where loaded and it asked me to continue to choose a restore point I pressed cancel and rebooted. The problem is now non existant in windows. Before shutting down I turned off the 'Dynamic Brightness Control' in PowerManager. Now I can't reproduce the problem and I've even tried three times.
I don't know if it's the Magic Blue button or if it was the PowerManager settings (the latter being more plausible) but for now I am one happy fella.
A strange thing I noticed is that all the checkboxes for the 'Dynamic Brightness Controll' are still checked, even though the feature seem to be disabled since I the screen does not dim. I guess it's nothing to worry about...
EDIT: This is still not solved! Sometimes the ghost display is there, sometimes not...

Macbook pro retina ghost image problem

I have heard about the burn-in problem on macbook pro retina display especially on LG screen. After I got my macbook retina for 3 months, the ghost image problem become really really unacceptable. After 4~5mins, the image on screen will burn in obviously for quite a long time. IT IS VERY OBVIOUS!! So I drop by apple store and find a genius, he did a persistence test on my macbook. The test is under a very low brightness, and I can not even know how he was operating. After 6 minutes, he said there is no burn-in problem. He explained that, if my macbook pass the test, it means my screen is within inspection. But I can tell if this screen is good, APPLE you should take a look at your inspection and change it RIGHT NOW. Everyone of my friend who have seen the problem on my screen says it is unacceptabe, how can it be within inspection? If anyone need a photo of that, i will provide.

Good work...
Back-up all your data.
If they replace your MacBookPro, you can avoid a service charge for runniing the back-up for you.

Macbook pro retina with ghost image problem

Can i claim my retina display that have ghost image problem?

Hi there, I had the same problem with my Macbook Pro 15`` Retina. And here is how you can find out if you have ghost image problem. There are two retina display manufacturers for Macbook Pro Retina`s LG and Samsung. And if you are luck you will have the Samsung Retina Display on your mac. Here is how you can find the manufacturer for you Macbook.
Go to your Applications folder and launch Terminal. Paste in the following and hit return:
ioreg -lw0 | grep "EDID" | sed "/[^<]*</s///" | xxd -p -r | strings -6
Look at the beginning of the second line to see which manufacturer made your display. If it starts with LP then you have an LG display. Samsung displays start with LSN.
If your display shows LP you might have this problem for sure. So here is how you can test your screen.
A simple test to check your Retina MacBook Pro display for image retention also reported as "ghosting"
http://www.mitchmalone.name/retina-test/
Run the test for 10 Min. and you will find out if you have this problem.
And if you have it, and if you are still under waranty the Apple will replace the display with Samsung for free of charge. I hope this information helps.

Not able to install/update HP dc7600 video driver - getting blurry/shadowy/ghosting display

Dear HP Windows XP Specialists, I am having difficulty fixing a blurry/shadowy/ghosting display screen (HP 19inch monitor) on a HP dc7600 SFF (2.99 GHz, 1.0 GB RAM) Desktop PC, which runs Windows XP Professional. It has been working fine for many years until yesterday, where I have replaced the monitor with another working one that works for half a day.I have updated the Chipset SP38488 and Video driver SP37615 but ended up with the following error which I don’t believe it is correct: “This computer does not meet minimum requirements for installing the software. Setup will exit” The problem is Windows XP kept prompting to install video driver after every reboot, and the driver it is looking for is SP37615. Allow it search through a Windows XP installation disk did not work either. It doesn’t or allows me to use standard video driver either. The only idea left is to add more RAM, but find it hard to believe since the display driver (not clear which one that was), has been working without the need to add more RAM. The part and serial numbers for this PC are PU700AV and AUD6110155 respectively. Any advice to assist would be very much appreciated.Thanks in advance,Jack

Hi: According to the specs I found online for the product number for your PC, it has the onboard Intel graphics. See if the XP driver directly from Intel works for you...this was the final release. https://downloadcenter.intel.com/download/16835/Intel-Graphics-Media-Accelerator-Driver-for-Windows-XP-exe-

Wierd lines on my display and frequent lock-ups w/ and w/o display problems

When booting I sometimes get weird lines and blocks on my display (the GRAY Apple screen) and then it hangs, other times the computer will boot and run fine for 20-30 minutes and then the display goes wonkers with blocks and lines and the computer does not respond. The only way I can get it to boot is to reset the PRAM by letting it CHIME 3x and then occasionally it will boot without issue and run, while other times I still get the blocks and lines on the display.
When I am able to get it to recover and re-boot after the lock-up and display problems and occasionally the box in the middle asking me to re-boot similar to a kernel panic the OPS gives me the option to REPORT the error and here is the error for others who would know more...
Thank you in advance,
Darren

Anyone know what is causing my problems? I thought it was heat so I downloaded a CPU and FAN temperature monitor and the CPU was getting VERY HOT at first so I then ramped-up the CPU FAN SPEED to maximum - it turns out the CPU FAN was not rotating well at low speed - since then I have cleaned and checked the fans and they all work as they should and blow on high(er) when the CPU temperature is above a certain level.

Is there a kb article or something that would illuminate what to look for in these logs, or is it a matter of learning by osmosis?
Both. I am not skilled in reading logs. It is a very technical and time consuming task for the uninitiated (me!) In scanning a log I look for the backtrace and loading dependencies. The first item in the backtrace is usually the roadblock.
Beyond that you can look at the Technical Note TN2063: Understanding and Debugging Kernel Panics

Display Problem with RowHeader of a Scroll Pane

Hi,
I am trying to display row headers for a table using another table
Here is the code
import javax.swing.*;
import javax.swing.table.*;
public class RowNumberHeader extends JTable {
protected JTable mainTable;
public RowNumberHeader(JTable table) {
    super();
    mainTable = table;
    setModel(new RowNumberTableModel());
    setRowSelectionAllowed(false);
    JComponent renderer = (JComponent)getDefaultRenderer(Object.class);
public int getRowHeight(int row) {
    return mainTable.getRowHeight();
class RowNumberTableModel extends AbstractTableModel {
    public int getRowCount() {
      return mainTable.getModel().getRowCount();
    public int getColumnCount() {
      return 1;
    public Object getValueAt(int row, int column) {
      return new Integer(row + 1);
}and then
        JTable displayTable = new JTable(...);
        scrollPane = new JScrollPane(displayTable);
        JViewport jvp = new JViewport();
        jvp.setView(new RowNumberHeader(displayTable));
        scrollPane.setRowHeader(jvp);the problem I have is that when a row is selected inside the row header, some rows go blank and you can see the selection is all screwed up. I tried setting the selection mode to ListSelectionModel.SINGLE_SELECTION but that didn't help.
A refresh of the entire screen (minimize/maximize) seems to resolve the problem. I am using jdk1.4.1 in Windows 2000.
Any ideas?
Sylvain

Again the problem is that when you click on the row headers, some row header rows go blank (completely white) so you can't see what they show.
ie say I have table
Row 1 - 1 2 3
Row 2 - 2 4 5
Row 3 - 5 7 7
Row 4 - 5 6 7where Row X is the row header. So for example, if you click on Row 2, you will get something like
Row 1 - 1 2 3
Row 2 - 2 4 5
      - 5 7 7
Row 4 - 5 6 7until the screen is refreshed or you click some other row header.
hmm ok, I added calling repaint on the table whenever a row is selected and at least the display problem goes away; however, the selected indexes from the event don't always match the index of the row selected. I think actually that may be the source of the display problem.
Here is the code I added in the constructor:
        getSelectionModel().addListSelectionListener(new ListSelectionListener()
            public void valueChanged(ListSelectionEvent e)
                System.out.println("Header table selection is: First = " + e.getFirstIndex() +
                                   " Last = " + e.getLastIndex());
                RowNumberHeader.this.repaint();
        });

Hi G5 Gurus,
The display problem first, we all know when screen savers display, a click on the mouse will bring you back to the active desktop, this was how it worked., but now, sometimes a click cause the G5 to sleep!
As for the sleep, I dare not to put it to sleep these days, because I am afriad it may cause a fire by over heating. Sometmes, actually four times in the past few months, my G5 could wake up by itself, followed by a extrem high speed running of the cooling fan, it sounded like a hair dryer running in the same room. Sometimes the sreen could light up, just like real wake up, sometimes, it was black. No clicks the mouse or keyboeard could bring it back to normal, I had to press and hold the power button to turn it off.
This crazy problem happened for the first time last summer, a dead hard disk was the cost. Apple replaced it, but failed to detect the cooling or power or display problem. I was given one month extended free service, but right after its end, the problem was back and happened even more often.
Please let me know if any of you had the same problem and please advise what to do.
100s Gs of thanks.

I have the EXACT same problem. In fact, I could not have described it better myself. What gives? I brought it in to the "genius" bar and they repolaced the power supply free of charge but the problem is still there. I noticed they ordered a new logic board but did not end up replacing it after all. Did you have yours replaced and did it work? Is this a known issue?

Hi La teller,
Thank you for your reply. The 'genius' here in London only replace the dead hard disk, which I belive was a victim of this problem. I was told they couldn't find anything wrong with the power supply or the cooling system.
Now at lest I know I am not the only bad luck guy. Let's wait and see if others are having the same problem. I am not sure if this is a known issue to Apple, even if it is, it may take years before they can offer a recall or free repaire. I noticed that some G5s have already been suffering from power problems and a free repaire was offered.
Thank you again and hope Apple can take our concerns into their consideration soon.

Hello,
I'm also having this problem (fan running, won't come out of sleep), just spoke with an apple care rep. He confirmed my suspition that it was software, not hardware as I have just had the logic board and power supply replaced.
His suggestions were to:
1. Run disk repair from the startup CD
try running OS X from a firewire drive and see if the same behavior happens or
perform and archive and install.
When the fan starts to run like that it means the OS is not communicating with the hardware properly. The OS could be somewhat corrupt if you were having hardware issues beforehand, hence the need for a reinstall. I will be performing an archive and install after the disk repair, I'll let you know if it fixes the problem!

Hi Stopha6,
Thank you for your message. I never imagined it could be a software issue, cos it looked so hardware.
Please keep me updated with your progress.
By the way, as I said in my old posts, a hard disk went dead when this happened for the very first time, how do you read this?
Thank you.

Hi Stopha6,
After reading your reply again, I realized that the system had already been reinstalled. As I said when it happened for the first time, the hard disk died with it, which was replaced, of course with a new OS X, but the same problem is still happening. May this suggest that it is not just a software problem? Thank you. Songyan

The Fans going at full is only because you have an application that is using a lot of cpu power and therefore causing the imac to heat up so it turns the fans on. The screen-saver and sleep problem you describe sounds like something that may just happen on accident. But this sounds mostly like a software problem. Try making sure to always quit all non-apple products and see if anything changes.

Thank you, Ag-Nate. I will try as you adivised but I con't think the fans were activeted my intensive CPU using. In most of the cases, the problems happened when the Mac was sleeping, when the minimum CPU were being used.

"The Fans going at full is only because you have an application that is using a lot of cpu power and therefore causing the imac to heat up so it turns the fans on."
That's only partly right. A hard-working process will make the fans run at high speed, of course.
But, the OS is in touch with the firmware of the iMac, telling it how to run the fans, based upon information the OS X kernel is getting about the state of the hardware.
If the firmware loses touch with the OS for some reason, and is not getting instructions on how to run the fan, it will default to running them at full blast, to be on the safe side (and this "full blast" fan mode is way louder than anything you'll generally experience during normal usage, I know from experience).
So it may not be so simple as a hard-working cpu process kicking the fans on.

Hi I have a 20" G5 imac it's about 18 months old and I am having the same problem, It freezes and the fan runs really loud. It's nothing to do with software as my I.T. guy has done a complete re-install. All of our admin people have imacs of differring ages and the flat panels are all OK but every one of the G5s has had a booting problem. Some fell into the recall for replacement logic boards but the one I have at home is the newest and doesn't. I'm waiting for my apple reseller to get back to me, but it looks like it's the logic board and as none of the serial numbers fall into the recall, I'm expecting a big bill. I'm really disappointed as I've been a professional apple user for over 15 years and have grown to expect a certain amount of honesty and integrity from them. Looking at all of the discussion boards and the amount of people complaining of the same problem the logic boards are defective and apple should be replacing these free of charge.

Kensall,
Welcome to Apple Discussions!
As in the other thread I wrote:
Being from England, you may find the repair program under these pages:
http://www.apple.com/uk/support/imac/repairextensionprogram/

Check both of them as they refer to different models.
If neither of yours is under the program, please start a new topic thread so someone can help you.

First off, you'll get a wider audience who may be able to solve your problem. Secondly, responses to you won't confuse the original poster with solutions that don't apply to them. And thirdly, you'll know for certain whether or not a response applies to you.

I am having a very similar problem. My G5 imac has already had the logic board replaced from the leaking capacitor problem. 8 mos. later the power supply was replaced under the second recall program when it failed to start up.
It had been working now for almost a year, when about 3 mos. ago I started to experience the sudden dimming effect - if the display was untouched the screen would dim about 30% similar to a laptop in energy save mode. I checked and none of these types of options were set in the pref panes. At the same time I would have the iMac go to sleep after a while from non-use, and then when I tried to wake it it would stir for a few seconds and then go right back to sleep. It took 2-3 attempts to wake it up.
Then last week, as I tried to wake it, it just shut down instead completely. I had to hold the power button down to recycle it to get it to come back to life (3 times).
Today was it - I found what I thought was a sleeping iMac, but it will not power up at all. I opened the back cover and the power supply is working, but I cannot get the board to energize, I reset the PMU, but the #2 LED won't even blink. It is completely dead.
Basically every time I used this computer I held my breath that it would not work. After 2 recalls I still only get 9 mos. out of it? Apple is really starting to show it is like the "big" computer makers, the quality is going right down the tubes.

Why is netflix having display problems on my macbook pro... HDCP compliance?

Watching Netflix and all of a sudden it says "Display Problems" Make sure your monitor is HDCP Compliant and is not setup for mirror airplay??

The issue is from Safari defaulting to HTML5 vs using Silverlight like it did in Mavericks.
So the options are, if you want to use Safari goto your Netflix account, playback preferences and turn off HTML5. This will revert to Silverlight and will AirPlay fine*in Safari.
If you want to use HTML5, just leave the setting for HTML5 on in Netflix and use Chrome, Firefox, etc.
You can't currently have both Safari and HTML5 Netflix when using AirPlay. You'd think Safari would be a little bit more powerful with Apples stances on browser extensions.

Display Problem with my Mac Pro and LG Flatron Wide Monitor in Mountain Lion

After upgrading to Mountain Lion, my Mac Pro has display problems with my LG Flatron display. The image is displayed with a black bar on the right and on the bottom. And the left side of the content is not visible. I tried every resolution available in the Display System Preferences, they are different in terms of how big the black bars are, and what part is not visible, but none of them are correct. I held down the option key to try to detect displays or switch to resolutions that are not normally available. When I restart the image is lined up with the display, but if the display ever goes to sleep or gets turned off, the image reverts to being off center, and the only way I can get it back is to restart... The interesting thing is that this monitor works fine with the same machine if I reboot using BootCamp into Windows 7. The Monitor also works fine, connecting the same connector to a Mac Mini, although that mac mini is running 10.6 and not Mountain Lion. I've reset the SMC and restarted countless times, I don't see any other levers to pull or things to try...

That card is for a PC it may not give you Startup and Option-Boot screens.
The 7950 "Mac Edition" card has a very distinctive look:

Weird event display problem in week view

Hi. I'm getting a weird display problem in week view. First time this has ever happened.
Some events appear to be missing, but when i double click on where I know the event is supposed to be, a new event is created (as excepted), and the missing events suddenly appear. When i move forward or back by a week, and then return to the week in question, the missing events are gone again. But, I can see the missing events in day view or month view.
Any ideas?

Dean,
Next, try reinstalling the Mac OS X v10.6.2 Update (Combo).
If that is unsuccessful:
1. Use iCal>Export...>for each one of your individual calendars.
2. Delete all but one of your calendars.
3. Create a calendar and name it "Test."
4. Delete the calendar which remained after step #2.
5. Quit iCal.
6. Remove the iCal plist, and drag the iCal plist file to your Desktop.
7. Log out/in or restart.
8. Restart iCal and use iCal>File>Import...for each one of the calendars that you exported in step #1.
9. Delete the "Test" calendar, and any "Home/Work" calendar which was automatically created when you opened iCal in step #8.

Windows 7 64 bit on iMac display problems and instability

I received my iMac 27" quad core with 8 gig ram & 2 x 1 TB hard drives last Friday. I'm using Boot Camp to run windows 7 64 bit on maximum 2560 x 1440 screen resolution.
I get intermittent but often display problems in windows 7. I get areas of the screen covered in little yellow dots or blue squares (never red artefacts.) This will happen at random areas of the screen, inside an open window, around borders of windows and so on. Most often the screen will go black and come back with a message in the bottom right corner of the screen saying 'Display driver has stopped responding and has recovered' with the sub message saying 'display driver ATI radeon family stopped....etc'. Sometimes I lose the screen wallpaper. Once I've had the system just shut down, once I've had Photoshop seize up and I had to do a cold reboot. Could this be an overheating problem or resolution too high problem or driver problem? Windows 7 tells me my drivers are up to date. I tried installing the drivers for the card from ATI's website which made no difference
The reason I bought a Mac is because it's the only effective way to code for the Mac family of OS's in XCode. The reason I didn't just attach a miniMac to my PC monitor was because there's rather a lot of advertising by Apple about the fact that you can use a Mac with a PC OS via Apple's own Boot Camp. Now I have a lot of Windows software (some of which is not available for the Mac or requires buying again) sitting on an unstable system. Any ideas would be much appreciated...

Sorry, that thread got moved for edit and as a user tip... which I didn't want and won't be doing....
Here is the post:
A tip and workaround for how to get ATI mobility/laptop drivers so that Windows no longer thinks the ATI is a desktop card:
http://discussions.apple.com/thread.jspa?messageID=11286987
Summary (my own edit steps):
1. Install Boot Camp 3.0 and upgrade to 3.1
2. Uninstall graphic drivers and run Driver Sweeper
http://www.guru3d.com/category/driversweeper/
instead of:
removing the crashing driver by going into windows 7 setup via its install cd and deleting the ati driver manaully
3. Install ATI Mobility (link)
4. Uninstall ATI (Programs control panel?) Device Manager (rollback; uninstall?)
5. Device Nanager: update driver and BROWSE BACK to 8.681 (the original apple driver that was causing freezes and purple artifacts) - navigate to /Apple/Drivers/ATI
(Apple uses) a 4850 card in the iMac, its modified a bit for apple. Enough that desktop drivers don't work, and modded-for-laptop desktop drivers don't work either.
Now the upshot of using modified drivers is that it FORCES the catalyst control panel to be installed, meaning you get a few more options to mess around with the card.
I couldn't use the original apple drive, it locks up, the newer one had banding, the newer radeon drivers direct form ATI wouldn't work until they were modded and then they cause black screens.
SO the solution, as obscure as it was, was to download ACTUAL mobility Radeon drivers - version 10.3 still, but made for laptops.
http://support.amd.com/us/gpudownload/Pages/index.aspx
THESE drivers I was able to install - and here is where things changed.
THIS driver changed they way windows saw the video card in device manager.
As I mentioned before, its NOT a desktop card, its a modified laptop card, but installing mac drivers makes windows THINK its a full desktop card, and running the original 8.681 driver crashed it.
Once installed 10.3 LAPTOP driver it now appeared in device manager as a MOBILITY card.
+These Steps "should" work:+
delete ATI driver manually
reinstall apple driver after that and see if that works,
otherwise try the steps above
(mod drivers, remove via windows recovery off setup disk, install laptop drivers, reinstall apple driver over it)
