So I have this collection of pixels near the bottom of my screen but they're only visible over a dark grey area, like when you're in the login screen (I have an early 2013 MBPr 15 btw)Â
It's probably a problem with the screen itself and not the GPU (or maybe the connection between them?) since if I take a screenshot it's not visible and I've connected it to an external monitor and it doesn't have it.Â
I took a picture of said problem [URL] .....
I've had this for a few weeks now and I've tried those youtube videos (I just to have some image retention after leaving something to run for a long time) which have decreased the amount of pixels. They all dissapeared for a few hours and now they're back.
Sometimes the LCD display goes into this mode where in some areas you see red and green pixels flashing. I have taken a few pictures, which obviously don't render the flashing effect, but give you an idea of what it looks like:

This is a MacBook Pro pre-unibody The graphic card is an ATI Radeon X1600 I ran the TechTool Deluxe tool to test the video RAM (and everything else), but it didn't detect anything wrong I have never seen this when the laptop is connected to an external monitor This doesn't happen that often; say 1 times out of 10, usually after the laptop comes out from sleep. The issue stays for a few minutes and then goes away until next time, so I am unlikely to have the problem when I go to Apple Store for service.
I have had my MacBook for just over a year. A weeks ago, the display started go weird: - strange shapes started appearing on the desktop - a fluorescent green (like vertical strips of 5 or 6 pixels in a group), sometimes as a shadow of a previous open window, sometimes just random squares or lines. The blocks of green go if i run my mouse over them with the button pressed down. -a fluorescent green light sometimes shines around the programme tiles in the dock. -shadows behind open windows very accentuated and fluorescent green - sometimes text on web pages and documents look garbled - again this goes if i run my mouse over them, and either go or comes back in a different place. Some times i can go a few hours without experiences these problems, other times the issue is there on start up. I ran the quick hardware check, and no problems were reported, a week later i ran the extensive check, and again the system seemed fine.
I have a Mac Pro 1,1. Tonight the display starting looking like the screen shot attached. Then it wouldn't come up at all. Black screen, with a few bands of green pixels.Â
My first thought is that the Graphics Card is going bad. Odd thing is, though, that I captured this via screen capture from another Mac. Could it still be a bad GPU if it looks this way remotely? I'm not sure how these early Mac Pros work. I have Mac minis that, when the display is off (or headless), the GPU is not used to render the GUI via screen sharing. So, I tried disconnecting the display from the Mac Pro, and I get the same screen shot.Â
I can boot the Mac Pro into Safe Mode, but that is it.Â

while surfing the internet (I was reading an article on CNN and scrolling down to continue reading), the screen color changed to tinges of green and purple. The entire thing froze...no keys, no mouse, not even force quit...nothing. I had no choice but to do a hard shut down by holding down the power button until the laptop just shut off (Macbook Pro). In the middle of rebooting, (at the grey screen with the apple logo on it, I got the familiar circular dial that ticks around as it loads) a screen wipe similar to the effect of some screen savers went from the top of the screen to the bottom turning the screen from grey into green and purple vertical stripes.
It also said "you need to restart your computer" and proceeded to tell me how to do so in four different languages. Upon doing so, the same thing happened...several times. I tried booting it into safe mode by holding down the shift key until the grey apple background appeared and it seemed to be working as the loading was taking forever. Alas, the same thing happened. I took the battery out and held down the power button for 10 seconds, put the battery back in only to suffer the same effect. The next genius bar reservation isn't until Friday.
I have a first generation macbook pro, recently i have been getting neon green and purple blotches appearing on my screen. I was also having a hard drive problem so i swapped that out and installed a fresh copy of OSX 10.4 on there and was still having the green and purple show up so I know that it is hardware related. I also have hooked up an external monitor and they show up on that monitor too so I konw the problem is not related to my monitor.. I downloaded fan control and have found that if I keep my macbook under 53 degrees C then They wont show up nearly as often but they still do. The only problem with this is that to keep it under 53 degrees C then I need to have the fans running extremely fast the entire time which is not really solving the problem...any suggestions?
It kinda looks to me like I need to get the logic board replaced, what does that entail.. can I do it myself? im pretty good with computers and electronics. I don't have apple care and the warrenty has definelty been voided or is expired..what kind of $$ am I looking at?
I have a late 2008 version of the 17" MacBook Pro. I've been using it today and it's been completely fine. that was up until I was uploading my recent holiday photos to iPhoto. I left it to upload and came to check on it after 5 minutes. I found the program had frozen and pink and green pixels were spotted all over the screen.Â
I turned the laptop off by the power button. When I started her up again I found the white screen with the pink and green pixels everywhere and apple logo appear. It starting booting and then just stopped. the screen froze and nothing was working. I've tried booting up in safe mode and again it just freezes. I've included a photo I've taken if the frozen screen.Â
for the last week or so my MBA has been showing a ~3 inch bar running vertically along the middle-left of the display. Until today, the area looked just like blurry pixels (some things like graphics would still appear, so I don't believe the problem is with the pixels themselves). Now the area has become a gray bar of pixels.
I have an early 2008 version of the 17" MacBook Pro. During the process of uploading photos to iPhoto, the screen froze and pink and green pixels appeared. I shut down by the off button and upon on turning it back on found the screen as shown below. The apple appears and then the clock spins for a moment then freezes. I cannot get any further.Â
I've tried booting in Safe Mode and other options I've read when trying to boot but to no avail.Â
Someone said I need to run the AHT but as this was purchased from a friend, I don't have the installation CD's. I've found a DMG file of the AHT but am completely at a loss as to what to do with this.Â
What is the significance of the purple and green colours when I put music to my project? I am able to edit the "green" music but NOT the purple music. Is it possible to do panarama/photomerge in iPhoto?
To see how it looks: [url] I can not find the cause of its pixels that appear on the screen. Only in the viewer. They occur randomly when I add an effect FCPX. (not just a plug-tier) These pixels are found embedded in the video if I made ​​one!It does not appear immediately launching FCP but after 5 minutes after playing withthe settings of my corrections.When they appear in FCP if I run photoshop, I have the same pixels in the window of my image in Photoshop I did not think I shall give my card GT120 But I have an ATI 5770 with an Apple MacPro 4.1 What I tried: reinstall FCP New partition with 10.6.8 and 10.7 fired FCP preferences Reset PRAM + SMC Changed the cables and adapters of my screens Does this card is defective? Why do they not appear in the screenÂ
I have the 9C9E display. Is this a good one? Also, the colors on MacRumors look purple, where on my moms 2.4 Macbook they looked blue. Especially the thread links. What do I do?
My tibook .867Ghz was working fine this morning, but now when I restarted it this afternoon, the colors are all off (lots of green and rapidly vibrating pixels in background). The computer works, I can run programs and so forth. There are no changes to the displays settings, still 1280x854 and colors "millions". When I switch to thousand or 256 colors there is no significant change.
I recently purchased a ColorVision Spyder 2 to calibrate my MacBook Pro display (I have the 9C83 panel). The results were wonderful—everything seemed to improve colorwise. There is one exception, though: in applications that use ColorSync (Safari, iPhoto, etc.) blues turn purple. Not just a purpleish-shade of blue—purple. The easiest way to see this is by opening a color picker, such as the one in Pages or Adium. Using the RGB sliders to choose a perfect blue—255—it's easy to see that it's purple. Other interface elements changed, too: blue menus, such as when you organize bookmarks in Safari, become purple. I found a long thread about the issue here, but no conclusion seems to be reached. It looks like the color spectrum created by these hardware profilers puts blue very far away from the sRGB blue, causing an adjustment to purple. A lot of people here use calibration tools on their MacBook Pros—has anyone else seen this? And you if have, is there a workaround?
So after waiting 4 weeks my High-res Glossy MBP FINALLY arrived...I was so happy. Got home switched it on and WOW it really is a beautiful machine...After using it for about 30 mins however i noticed a small dot to the lower right half of the screen... I looked closer and realized it was either a dead or stuck pixel( I dont exactly know the difference). I did a few test on it, and its ONLY visible when a light color is on the screen (White, Gray etc) However when the screen is DARK blue, Dark green or black it cant be seen at all...
It kind of looks like a TINY speck of water or liquid the size of 1 pixel stuck under the glass... I noticed that it does get lighter and darker when i adjust the brightness of the screen. Can anybody give me some tips? Anything i can do to fix it? Is it in fact a dead or a stuck pixel? I tried the JSscreen fix which is basically a online tool that opens up a flashing screen...Ive had it on for about 30 mins...but no luck
2 years ago I had bought this iMac 2GHz Intel Core 2 Duo and its on version 10.5.3. It came with tiger and when I installed leopard I started getting all these red pixels. I have no idea if its a software problem or hardware problem.
I recently bough a 2nd hand MacBook Pro off eBay & all has been fine until today when I was using it. Suddenly a green line appeared down the right hand side of the screen. I did a bot of research & people say it could be the GPU, but I know that this particular MBP has had the logic board replaced only last year. I'm not entirely sure what it is, but the line has now gone.
Over the last week, my 7 year old Powerbook G4 began showing faint pixels in the background which is more obvious if you are scrolling over menus also when a menu is highlighted. Unfortunately this seems to be affecting DVD playback because it will show blinking green vertical lines inside Front Row. This image within OS X 10.5.8 will show what I mean: [URL]. Does this means the graphics card is failing?
I bought an iMac yesterday, and today i've noticed there is one stuck pixel, what is Apple's dead pixel policy? now I bought this used but I have the original receipt and obviously theres still warranty on it. I just noticed another stuck pixel
I'm on my third LED Cinema Display (for various issues) but I've noticed all of them have DOZENS of very tiny specs of color that are only apparent on a black screen. Furthermore, they seem smaller than an actual pixel (have to be up very close) and they are only apparent at certain angles (and even sometime change color) as opposed to dead/stuck pixels. These always pass my initial dead pixel check over a full black or white screen but I find them once I get in real close.
just purchased an NEC Spectraview LCD2690WUxi2 display (1920x1600 26" LCD SIPS panel), and fonts are aliasing strangely, almost as if they are not falling "on the pixel" in the OS. It's not a "big" problem but is clearly noticeable in my transition from my 23" cinema display. This is particularly evident with small fonts or italics. I'm really hoping that there are settings either in OSX or on the display that can fix this issue. Images look absolutely fantastic BTW�tack sharp, no banding, phenomenal color. In that respect this blows my old 23" Apple display completely out of the water. So it's likely something in the OS, no
My mid-2014 15" Macbook Pro randomly "loses" its retina display at the top menu (becomes pixel-y), where the battery, sound, and wifi logos are (on the top right side of the screen). A restart fixes the issue, but I want to know if this is an issue that can be fixed?Â
I've got two iMacs in my posession currently from getting replacement machines. Both have screen issues as follows: iMac A - dead & stuck pixels, feint grey horizontal bar running along bottom portion of screen, bottom left corner has noticeable backlight bleed. iMac B - dead & stuck pixels, yellow tinge in bottom portion of screen. So here are my questions. Which iMac should I keep and submit for repair? (does it matter and why or why not?) How does the actual repair get done? For example, if I submit iMac B for repair, could I end up with a grey bar or backlight prob like in iMac A?
Are there multiple layers to the display when they fix specific issues? For example, let's say the dead pixels are on one layer while the yellow tinge is on a different layer, or are both issues on the same layer? I ask because if there are two or more separate layers, there is more of a chance to mess up so I may want to submit the iMac that has the least amount of issues.
Lastly and most importantly, has anyone submitted their iMac for screen repair for these issues and got it back 100% repaired? (no dead/stuck pixels, yellowing, grey bar, backlght bleed) These are #4 and #5 in terms of the number of replacements I've gotten now and I'm sick of it so I may opt to go for repair on either of these existing machines instead of going for replacement #6. But do you think a 6th replacement would be better than going for repair on either of these? Or not?

a fluorescent green light sometimes shines around the programme tiles in the dock.
I have a 2007 Mac Pro 1,1 with attached 24" apple display and utilizing 5 GB Ram and maxed out on internal hard drives. It's been a flawless workhorse and I mostly tax it with Photoshop which it does well. Well, yesterday, I was viewing a small video on my Mac when this issue occurred. Suddenly I saw these squiggly looking horizontal lines on my display. Then I saw a spinning beach ball. I had to shut down.
I double checked my display cables in case any were loose - no issues. Restarted without issue. Went back to work on my computer - no issues doing ordinary tasks such as opening windows, moving files and surfing the internet. Went back into Photoshop and resized several dozen images without issue. Then, this happened again... restarted. Zapped PRAM just in case. Fired up Tech Tool Deluxe (older version 3.1.3) and it found NO problems, I passed all tests.Â
Then... out of nowhere it crashed again, third time... I don't recall what I was doing to be honest. I shut down my Mac last night and this morning have spent an hour on and so far, so good. However, I'm not taxing it by doing anything intense. I need to use Photoshop for a project I'm working on so I will do that soon and see if this issue repeats.Â
I've tried searching the forums but can't find anything conclusive to my specific issue. What else should I do? What else should I check? Is this hardware or a software issue? I have temperature monitor installed - should I be looking at specific temperature increases and if so, where?Â
GPU going bad on logic board? This is a really close up image taken with my iphone, obviously the lines aren't this large.
I have the 17" ASDisplay attached to my PM G4 MMD. It looks and works perfect. Love it. I use this machine for video capture so I don't need screen real estate.
Fast forward to yesterday - I ordered a new mac pro and need to connect it to my KVM switch which means I need to remove the G5 from that switch.
No biggee - I found another 17" ASDisplay. But i thought i better check with my own first before committing to buy.
It connects to the ACD side of the graphics card (nvidia Gfx 5200 or along that line - stock card for this model), but everything has a green due to it.
