Monitor flickering blue? (Not from Display)

My Macbook '09's monitor is flickering blue. It's usually only the top right corner, 2x1", that's tinted blue. Sometimes it'll extend over to 4", sometimes it'll fill the whole screen (it usually does this when I push the monitor all the way back, but not always), and sometimes it'll just flicker randomly. (it does this while I'm holding it, without fail). Control of brightness isn't effected. I've tried taking a screen cap of it, and I checked it on a separate computer. There wasn't any blue, so It's definitely a hardware problem. I just have 2 questions.
1. Do you think it can be fixed without replacing the screen?
2. Do you think this is going to lead to other problems, such as the monitor stops working?

Hi Brett,
Thanks for your response, I'm on an iMac not Macbook but checked your link, All my software is up to date and there is no updates for the Asus and nothing for the mini dislayport to display port cable.
Everything works as it should via display port if i run bootcamp into windows 7 just not from OS X so would seem like a Mac Graphics driver issue perhaps??
I was hoping it would be a glitch that would correct itself by unplugging the cables or resetting the P Ram but no such luck so i am open to any other sugestions.
The iMac can see the Asus at all times just doesn't seem to send the signal to the Asus?
I would be happy to supply any logs that may shed some light on this issue.
Kind Regards
Mark

External 4k monitor says no signal from display port

HELP...
I have a late 2009 27" iMac running 10.10.2 Yosemite, i bought an ASUS PB287Q 4k monitor to extend my desktop. I have connected it by MDP to DP and the Mac recognises the ASUS, shows it as a display and tells me how it is connected but the display keeps saying "display port no signal"
If i run bootcamp and boot into windows 7 Ultimate on the same iMac the screen works perfectly giving me a 4k screen at 2160p to work on alongside the iMac with the same Display port cable.
If i use OS X with a MDP to HDMI connector the screen works as it should but with a max resolution of 2560 x 1440 only.
I have unplugged everything and re-connected, tried turning on the ASUS at different times, reset P Ram but still it will not work?
Obviously every part is working but just not from OS X
The ASUS is also set to display port 1.1
Please can anyone help????

Monitor flickered and not iMAC won't boot up

My iMAC 24; purchased in late 2008, the screen started flickering recently. Top half of the screen would flicker and the bottom half is black. The only option is to do a hard book by holding the power button. Now on the reboot I get the Apple icon and than the spinning gear but about 1 minute the gear stops. On some reboots I'm able to get in and everything is fine but than soon after the flickering starts up again. The strange thing is upon the reboot after the gear stops spinning it does seems to be still be running and the screen is just frozen. I saw post about a firmware update however I can't update the firmware because I can't boot up. I've tried booting from disk but I get stuck at the same spot. I tried booting in Safe Mode, I get the black screen with a lot of white text but that's it. The only possible error I see is, BootCacheControl: Unable to open /var/db/bootCache.playlist: 2 No such file or directory, but don't know what that means.
Any ideas and/or help?

Safe Mode didn't work, just gave me lots of details with no error.
Huh? Sounds like you booted in verbose mode not safe mode. And it fully booted or didn't?

LG TV as a Monitor - Problem with not Mirroring Display

I used to be able to extend to my LG TV and use that as an additional monitor side by side with my Macbook Pro 17" but now it only allows me to mirror. What has changed. I have tried different HDMI cables.

Mirrored mode mirrors the display including resolution. Use extended mode not mirrored mode to set the external display resolution to the TV's native mode.

How do I set the default external monitor setting to NOT mirror displays?

Greetings folks. I take my Lion macbook all over the place, and frequently plug into projectors to present. I NEVER mirror my display, and always use the projector and on-screen displays as separate displays, yet when you plug in a new projector to the MacBook Air (or MBP) it always defaults to "Mirror Displays" in the arrangement tab. Is there a way to change that to NEVER default to mirror displays?

I've tried that, and then created my installer, but it defaults back to having auto update checked, or in the ON position. I want it to default to being OFF so any new installs or upgrades that I send out do not turn it back on.
We manage all computers here, and do not want users doing any updates.

HT3209 Why in the heck can I not download an HD video if my monitor isn't capable of displaying the movie.   My iPhone can and will be downloaded to the phone.   So why stop me from downloading the movie?    Have I lost this freedom to download HD?

Never mind.   I bought the movie through my 4S phone.

IMac always auto detects for external monitors after waking from sleep or from display off

I've got a Dell 24" monitor (2408WFP) plugged into my mid 2011 iMac via DVI cord and thunderbolt attachment. Things work fine.
When I need to leave my computer, I usually turn the displays off using the shortcut keys: CTRL + SHIFT + EJECT
This works perfectly and both displays go black. However, when I return to my computer and reactivate the iMac, the iMac display will turn blue as if I have just plugged in a new monitor even the external monitor is still plugged in. It usually flashes blue twice before displaying the password prompt. I can usually just log back in as normal. I've never had this happen before using Snow Leopard. It's annoying but strange.
However, even more strange is that sometimes when returning to the desktop, the iMac will do the auto detect display thing and then when I log back in, the external display just shows static as if there is no signal. I've checked the cable a million times and everything is as tight as tight can be and both ends are plugged in properly. Unplugging the displayport adapter from the iMac and then reattaching it restores the desktop on the secondary display although sometimes, it results in the secondary display showing a gray background picture instead of my normal picture. Replugging the secondary display seems to fix that too although sometimes it doesn't.
Why is this happening?
- Problem with the adapter?
- Problem with the DVI cable I'm using?
- Compatibility issues with my external monitor?
I need to stress the point that this has never happened before with Snow Leopard.
If I am the only one experiencing this then I suppose it may be an issue with the iMac or adapter or even the cable. But if anyone else can shed light on this problem, I'd really appreciate it.

Hi Micheal,
I've been experiencing the exact same issue with my new iMac I just bought. I bought it refurb so I wasn't sure if it was a defect with the hardware or not. Since I'm not the only one I will asume it's not for now.
Setup:
- iMac 27-inch 3.4GHz (Release May 2011)
- Dell 2709W external monitor
- Hooked in with mini display port to DVI adapter
- Lion 10.7.3 all up to date to this day
From what I've been able to gather the issue presents itself only when my Dell 2709W enters "Power Save Mode" after I do CTRL + SHIFT + EJECT or when the diplays simply goes to sleep by themselves.
Although if I hit that combination and the displays goes to sleep but I don't wait long enough for my Dell monitor to actually "Power Save Mode" (wait like 2 sec) then touch the keyboard then the 2 displays (iMac and Dell) resumes from sleep without the issue presenting itself.
I'm tempted to buy the mini-display port to HDMI just to see if the issue is still present with that adapter. If I do I'll update my post with the outcome.
If anyone else has any info to help with this issue it would be greatly appreciated. It's very annoying when you resume from sleep and you find all of your windows that where opened on the external display before sleep squeezed into your main display (iMac).
Thanks!

My G4 Apple PowerBook will not boot further than pale blue/grey screen displaying "flashing file symbol / flashing ?"

My G4 Apple PowerBook will not boot further than pale blue/grey screen displaying "flashing file symbol / flashing ?"
Last previous action: Used Firewire cable and "Target Mode" to copy files from G4 eMac to the PowerBook.
I worked from the eMac to the PowerBook, making the PowerBook the "Target". Files seemed to transfer OK. Won't boot from InstallDisc. Holding down T on startup results in Target mode screen. I have a G4 iMac and a G4 eMac. Can I use either of these with Firewire cable to boot-up my PowerBook ?
I'm new to using this Communities & Forums Help. Can someone please help me to get going again ! ! Thanks for your time. Graflood

Hello,
It sounds to me like the PowerBook is stuck in target disk mode.
It's expecting the iMac/eMac to be there when booting. Seeming it's not attached, it will show a flashing folder.
If your PowerBook internal drive is bootable, then simply hold down the option key when booting and select it's internal hard drive. That should boot your PowerBook into Mac OS X.

Data is not getting displayed in the report from an Infoset.

Hi All,
I am having a report based on an infoset. This report is displaying the data in the Dev. envmt. When it is transported to the QA, it is not displaying the data in the BEx as well as RSRT, in the QA envmt. The patch levels of both the Dev. and QA are the same. The Queries are same in the Dev and QA also.
While trying to display the data from the infoset (rt.click- display data), i am able to view the data, in the QA.
Could anyone please suggest why the data is not getting displayed in the query designer.
Thanks & Regards,
A.V.N.Rao

Hi Ashish,
I ran the "ZPS/!ZPS" in RSRT where ZPS is the infoset name. In Dev, it displayed the values. In QA, it displayed the below messages:
ECharacteristic 0TCAKYFNM does not exist. Check authorizations
WThere are calculated elements. These results are bracketed [ ]
and below that, it displayed the values for Number of records. But, it has not displayed the values for the other figures.
Does this has any impact in QA.
Thanks & Regards,
AVN Rao.

Images from KM are not getting displayed in EP

Hi All,
I am using EP7.0 SP11.When I run the portal, the images are not getting displayed. When I right click on the * mark and click on Show picture, then also its not appearing.
Location of the Images that I received from EP is mentioned below.
http://hostname:port no./irj/go/km/docs/documents/HP_Images/Image_123.jpg
Images are available in the location in the below mentioned path as .jpg files:-
http://hostname:port no./irj/go/km/documents/HP_Images/Image_123.jpg
Difference in both is a DOCS folder missing in between........
Is this is the reason for the image not getting displayed?
Anything more has to be done in KM part to display these images?
May I know how to solve this issue??
Regards,
Athulya

Hi,
the right path look like this: /irj/go/km/docs/<path_to_document>.
You may have to check you URL generator service settings. Here:
Configuration - Content Management - Global Services - URL Generator Service(advanced section)
and then have a look for example for the following values "Content Access Path:" and "Viewer:" normally they both have same value "/irj/go/km/docs".
Hope that will help.
best regards,

Has your carrier been having issues with Call Display? Do the telephone numbers come up when people call, or does it just show 'Unknown Number' or 'Blocked' ?
