Green Pixels Along Image Lines on 30" Monitor

Over the last several years I have seen numerous posts dealing with the Apple 30" monitor and the green pixels on screen images which occasionally appear, especially after the monitor comes back after the sleep mode. I have had this problem for several years, but Apple seems to be clueless regarding the condition, which is difficult to believe, after seeing all of the posts. I know I can get rid of the condition by changing the resolution of the screen to low resolution and then bringing it back to high resolution. Has anyone found a definitive solution to this problem?

Sounds like we are having different problems. Two screen shots of my problem are here:

I took my display to an Apple Store today to test it with one of their MacPros (to rule out it being a problem with my Quad G5). It took a while and it started to look like the problem was beginning to appear, but we had basically run out of time and couldn't continue to see if the problem got worse.
Getting it to the store was the longest the display had been unpowered in quite a long while. So it would seem that the severity of my issue may also depend on how long the display has been unpowered.

Display Wake Up/Strange Grainy Blueish-Green Pixels...

When my display (30" Cinema) goes to sleep and I come back to the computer, the screen looks really funky. It looks like my desktop colors are slightly distorted - I see lots of blueish-green pixels (dots) and lines. I've been able to get it back to normal by lowering the desktop resolution and then raising it back up for quite a while, even putting the displays icon on top so I could quickly remedy this situation.
At least, it used to. Now, this no longer works. Even when I lower the resolution, the blue-green pixels remain... What gives? I have the GeForce 7300 graphics card and recently installed 10.5 (though this issue was there with 10.4 as well - alas, I was hoping that this would have been fixed! but no..)
Any help would be extremely appreciated.

You are not alone. I get these Blue and Green pixels all over the screen from all my Macs that have been updated to OS 10.4.11 - This includes my G5 running an ATI X800. My work MacPro with the top of the line Quadro card and 30inch Cinema Display and my MacPro 17 inch Laptop. This occurs after awake from sleep or sometimes after screen saver or screen sleep returns. I reinstalled my wifes iMac intel Core Duo 1.8 Ghz to 10.4.10 and it has no issues anymore. I would say it is definitely an "upgrade" issue. I have seen many with Leopard also have this same issue or similar issues with their video cards. - BTW this issue was also in the very first versions of OSX Tiger for some configurations, so it is likely a ghost in the code somewhere.
Current solution for those in Leopard - don't let your computer sleep nor use screen saver. ( Use up electricity and make our environment dirty ) Tiger same or go back to zero with your system and update only to 10.4.10 at most maybe leave it even earlier. Problem there is security updates. On Tiger.. I notice if I ignore all those funky blinking blue and green pixels on my Photoshop screen for a while they sometimes go away, but it does annoy.
I first saw this in Windows XP installed on the 17" Macbook Pro laptop and it makes it impossible for me to use the rest of my Adobe Production Suite, which is windows only. For this there has been no solution, as the video drivers Apple gives us on the X1600 mobiles does not work right and ATIs don't install. But, I was surprised when I saw the same issue start to show up in all of my Macs after updating to 4.11.

Green pixels on external monitor with MBA coming up from sleep?

Has anyone else experienced green pixels on external monitor with MBA coming up from sleep? I can get rid of these pixels either restarting MBA or switch off the monitor for a five secs and then switch it back on. These pixels do not show up within screenshots.. or neither on MBA own screen but they do reappear on external monitor (used with mini DP-DVI-adapter) after every sleep cycle.
http://ssh.nbl.fi/~nbl4264/gp/ (few pics where these green pixels appear on)

I have the same issue with my new macbook.
When i wake the computer from a partial sleep the screen flickers and i get line distortion through the image.
If i put the machine to sleep unplug the mini dvi adapter and replug it in and wake the computer up the problem disappears.
The issue is also intermittent doing about 3 times out of every 10 wake ups...
If anyone has any suggestions it would be great, I a using a new Dell 2208WFP monitor.

Flashing white/green pixels on external monitor

Hello everyone, I just purchased a 15" MBP with the hi-res antiglare monitor. I upgraded from a black Macbook, which was connected to my 24" Samsung monitor with a Displayport to DVI adapter. When I bought the new MBP, I also bought a new miniDisplayport to DVI adapter. I just now hooked up my MBP with the new adapter to the Samsung monitor and there are/were two issues.
1) When I imported my photos off of my DSLR camera, I noticed green flickering pixels stuck on the images. These pixels moved and flashed with the image, so I know they weren't dead. When viewing those images on my regular 15" MBP monitor, those pixels were not there. They were only on the external monitor. I thought this may be an issue with my DSLR/image import, but then I noticed random purple/green pixel artifacts on an ad on Facebook as well.
2) I reset the NVRAM, flipped the DVI cord out and around, and reconnected it. Now, the green pixels do not seem to show up BUT there are now tons of tiny white pixels flashing across my entire screen. I disconnected/reconnected the display connector several times, and I was able to recreate #1 once. I haven't bena able to again.
I reconnected my old Macbook with the old adapter to the monitor and there were none of these issues.
What might be the problem? I can't capture the pixelation effect on screen capture.
I'm thinking its either:
An issue of Mountain Lion
My Macbook Pro's software
My Macbook Pro's hardware
The miniDisplayport adapter.
Thanks,
-Max

Having the exact same issue. I'm getting the problem on my LG Flatron E2742 external display, from a Thunderbolt to HDMI out from my 2012 MacBook Pro running Mountain Lion.
The issue began yesterday when I connected my MBP to a HDMI Projector. I noticed, via the projected image, the beginning of the dancing white/green pixels. What's really weird is that when I connected my MBP back to my standard LG External display, the dancing white pixels were still there!
MAYBE it's something that happeend to my thunderbolt to HDMI cable in the process? Haven't experimented with another cable to confirm this. BUT, something tells me it's actually software related, because when I first plugged in my external display this morning, it began flickering/staticing/spazzing out like CRAZY. After some poking around and forums, I eventually changed my display color profile and it went back to normal, EXCEPT for the dancing white/green pixels.
Any words of wisdom out there about this situation would be much appreciated.

When i open my computer I get the white screen with apple symbol and there are vertical lines all over the screen with green pixels and after a few minutes the screen gets grey and I get message to restart my computer what happens

3 years ago I bought an IMac Desktop that I am using for a lot of things but the most important for dvd montage in Imovies and Idvd.
Now today when I opened my computer I get as usual the white screen with the Apple symbol but there were all over the screen vertical lines with green pixels and after a while the screen gets grey and I get message to restart my computer using the power button or the restart button and when I do so each time the same is happening somebody can tell me what is happening and what caused this. This computer is my work and now I have no income anymore.
On the Apple support site they are asking to enter the serial number and when I do so I get message it is wrong but it is the only one I have and I buy this computer in Cairo Egypt. I am living in Hurghada in Egypt for the moment. When I call the technical support of the shop where I buy it they are telling me that it is the hard disk or ram and that I probably lost everything on it and they are asking a big amount to repair.
Can somebody advise me on this matter. Thanks in advance

You can find the serial number either in About this Mc in the Menu bar under the , or it should be on a sticker under the foot of the machine.
If you have the install discs, try booting from them, holding down the c key and then using Disk Utility to check the drive.
You can also boot into Safe mode
To start up into Safe Mode (to "Safe Boot"), do this:
   1. Be sure the computer is shut down.
   2. Press the power button.
   3. Immediately after you hear the startup tone, press and hold the Shift key.
      Tip: The Shift key should be held as soon as possible after the startup tone but not before.
   4. Release the Shift key when you see the gray Apple and progress indicator (looks like a spinning gear).
During the startup in Mac OS X 10.2 through 10.3.9, you will see "Safe Boot" on the Mac OS X startup screen.
During the startup in Mac OS X 10.4 or later, you will see "Safe Boot" on the login window, which appears even if you normally log in automatically.
Please post back with results,
To leave Safe Mode in any version of Mac OS X, restart the computer normally, without holding any keys during startup.

My 06' Macbook Pro crashed with vertical, green pixelated lines and now will not advance past the turn-on screen with the apple filled with green lines as well. Then, it says to hold down the power button to restart. Help?

My 06' Macbook Pro crashed with vertical, green pixelated lines and now will not advance past the turn-on screen with the apple filled with green lines as well. Then, it says to hold down the power button to restart. I have tried several times to get it past this point but tnothing helped.
I have an appointment at the Apple store today, but was wondering : will all of the information and files on my desktop be lost? Or is this a logic board problem?
Any help is much MUCH appricated.

I'm not sure, if you're out of warrenty it'll cost quite a bit for the replacement of the logic board replacement...unless you have apple care. you could ask apple to try and recover your hard drive but i'm not sure.

Green pixel lines after installing 10.4.6

I started getting green pixel lines on my screen following installation. They appear when windows open and remain after windows are closed. They also appear around the desktop icons, but mostly on the left side and bottom of the icon.
Any thoughts on how to eliminate this problem?
I have run permissions repair several times.

jcaz,
Find the com.apple.finder.plist, and the com.apple.systemuiserver.plist file in your ~Library/Preferences Folder. Drag these plist files to your Desktop, log out/in or restart.
If unsuccessful, can you duplicate this behavior if you create a new user?
Reinstalling the Mac OS X 10.4.6 Combo for PPC is an option if the behavior is observed in the new user account.

AVI Clips Imported to CS.5.5 Has Green Tint and Colored Lines

NOTE:
I'm using the video monitor in the CS5.5 program.
Still trying to upgrage to CS5.5 and testing out the trial version. The new challange is the green tint and colored lines on the imported .AVI files.
Any tips would sure be appreciated. Thanks.

This is crazy.
These are AVI files in CS5.5 that have been used for over 10 years in other versions of Premiere.
If I double click on the Monitor when the video is paused, the color corrects to original. Play again and crazy green color and lines.
Now, if I play the clip without double clicking on the monitor window, the clip will play out green and pause green, but if I double click in the monitor window, the video will correct in pause, but still play out green.
Here's one AVI file:

Grey pixelation around my lines?

hi, i did a drawing using the pen tool, and whenever i colour in a section using dark colours- there is grey pixelation around the line. heres an example at full zoom:
[IMG]http://i50.tinypic.com/icofgh.jpg[/IMG]
anyway i can remove this? i noticed it doesnt come up with black/dark grey colouring but does with navy/dark green etc

i am doing screen editing, is there any way to convert my image to RGB? im new to illustrator so i dont really understand the colour modes yet
edit: i found out how to change from cmyk to rgb but my black lines now turn light brown when i use these dark colours to fill.
overprint mode is off
edit 2: it seems i changed the colour myself at some point. going to fix it now.
thanks for the help and marked as answered

30" with edge effects, green pixels?

Just installed first 30" display on Geforce 6800 DDL in my G5. All windows have a blue edge effect (left side usually) and green pixel fringing on the right and within many objects, icons, text.
Is this a symptom of a bad LCD?
I have a picture, not sure how to include in a post.
Dual G5; FCP Studio 5 + Mac OS X (10.4.7) JVC SR-GS30 deck, DVX-100a

I bought the original 17" MacBook Pro with a 30" Cinema and had the green/blue pixel issue right away. Seemed to only come after the display went to sleep. I brought it back to the Apple Store and they told me it was a bad graphics card and replaced the MacBook Pro. I took it home and the problem was still there. Next they replaced the 30" display. I took that home and had the same problem. I took in both the display and MacBook Pro and they couldn't reproduce the problem using their Cinema Display. The Genius told me it must be an interference issue and to try using the combination in a different place. I moved both to the other end of the house and had the same problem. Next they told me to try a power line conditioner. I bought a 1500VA backup and the problem was still there. Then I noticed that it only showed up when my laptop was closed (I thought I was supposed to be able to do that). I left it open from then on and all was well. Then I upgraded to the Core 2 Duo and got a different problem. Now instead of blue and green pixels, I get a snowy blue pixel dots and lines jumping all over the dark areas of the screen. I can change the desktop picture and it only effects the black or nearly black areas. Watching a DVD is painful - blue static everywhere.
I find it interesting that two different computers with the same video card and the same monitor have similar, but not identical problems. I found a fix in leaving my lid open last time, but I haven't found a fix for the Core 2 Duo. Anyone?

RMBP External Display Flickering Green Pixels

Hi,
I own a MacBook Pro 2012 with retina display and an LG W2363D (3D) monitor.
I have tried to connect my monitor with Thunderbolt -> DVI cables having 650M enabled. Moreover, I checked for DVI-D and DVI-I as the monitor only supports the former.
However, although the image is displayed on the external monitor I get green pixels flickering on the screen, here is a screenshot http://img19.imageshack.us/img19/2310/cam00042.jpgAlthough I have tried 3 different cables the problem remains the same...
I have also tried different resolutions rather than 1080p. The only way to limit the problem was to lower the resolution so that I could choose a refresh rate more than 60hz however this is not an acceptable solution for such an expensive investment.
What can I do? Is there an nvidia update that I could use?
Thank you very much in advance.

I notice the same with my external EIZO EV233W (DVI) on a mid 2012 non-retina MBP 15".
But strangely enough if I go to screen preferences, change the (external) screen mode to scaled (doesn't matter which mode), then change it back to "Best for screen" (so nothing has changed, since this was the default), the green pixels are gone ..
Kind of a hassle to do this excersise everytime I connect the external monitor, but it reassures me this is not a hardware issue in my case, just annoying.
EDIT: the other input (displayport) on this monitor is permanently connected to my Windows 7(64bit) machine, never had an issue there.
The DVI adapter for the MBP is a third party adapter

Horizontal line across the monitor. It happened yesterday.

I have a HP ENVY 23-c1 10xt AiO (Lavaca3-SB)PCUS and there is a horizontal line across the monitor. It happened yesterday.

Hello again javajohn23,
I would like you to try the following steps:
Step 1. Turn off the computer, and then remove the power cord
Step 2. With the power cord disconnected, press and hold the power button for five seconds
Step 3. Reconnect the power cord, and then turn on the computer
If the above steps do not resolve it try the next set up steps:
Step 1. Restart your computer
Step 2. Repeatedly press the F10 key about once every second for five seconds after turning the computer on
Step 3. Wait five seconds
Step 4. Press the F5 key. This restores the default settings of the BIOS
Step 5. Press the Enter key. This accepts the changes
Step 6. Press the F10 key. This opens the Save and Exit window
Step 7. Press the Enter key. This saves the changes, exits the BIOS, and then the computer restarts
Step 8. Restart the computer.
Another thing I can think to try is review the HP Support document: Changing Display Settings, Background Image, Icons, and Screen Saver (Windows 7) to see if you can identify anything out of place.
We can also try to reload the Intel Graphics Driver for your computer as it will wipe out the settings when the new driver is reinstalled.
Please re-post with the results of these steps. Thank you for posting on the HP Forums. Have a great day!
Please click the "Thumbs Up" on the bottom right of this post to say thank you if you appreciate the support I provide!
Also be sure to mark my post as “Accept as Solution" if you feel my post solved your issue, it will help others who face the same challenge find the same solution.

Avoiding pixelation with image resizing

i just redesigned my site (with a ton of help from many people on this forum--thank you nancy riki osgood
Sudarshan!!)
i have my thumbnails resizing (using max width: 100%) in a gallery but on a large browser window like my 32" monitor they get pixelated when they scale up, particularly the text..
is there a way to start with a higher resolution image and display them at a smaller display size so when they scale up they stay crisp?
http://toddheymandirector.com/
go to REEL, MORE and NEWS
thanks..

Hello mate, Welcome back!
Ideally, I wouldn't do a 100% width for your images on the site for enlarging them. No matter what plug-in you use, you'll definitely end up pixelating the image at least to some extent.
However, if you're definitely looking at achieving this, try this: http://archive.plugins.jquery.com/project/aeImageResize
And, start with a higher resolution of the image. The plug-in will scale it down proportionately depending on the screen dimension you're displaying it on, rather the DIV dimension that holds the image inside.
Also, it is to be noted that usage of multiple jQuery will lead to a performance issue on your site. You should keep this in mind.
One last thing: having said that you should start with a higher image resolution, your load time for the site will considerably increase as the plug-in only scales down the image visually, it doesn't load differently sized images!
If I were you, I'll keep the thumbnail images to zoom in to one optimal size and then provide a link inside my fancybox/ lightbox to a much fuller, bigger size image - if someone is interested in seeing them/ downloading the big size image.
