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.
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.
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.
I can boot the Mac Pro into Safe Mode, but that is it.

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.

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.
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)
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.
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.
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.
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.
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?
GPU going bad on logic board? This is a really close up image taken with my iphone, obviously the lines aren't this large.

Ever since the last QT update 7.6, my AVIs are so pixelated to the point where it's no use for me to edit them in FCP. They're more like thick white blocks that completely distort the image. I have both Perian and Flip4Mac up to date. I'm also using MPEG Streamclip to convert to a more friendly h.264 clip.
View 4 Replies View RelatedI 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.
It's a brand new iMac and a line of pixelation went out. It looks like it is bleeding from inside of the screen.

Ive got a new (ish) Mac Pro that has suddenly decided to pixelate the screen quite badly, little "dots" have appeared, & if I move something on the screen eg a window it blurs the text/image to the point where nothing is readable, it also sometimes leaves a partial trail. I have tried using a different monitor that works on another PC & the same fault occurs, so the fault isnt with the monitor. My system is..Processor 2.8 GHz Quad-Core Intel XeonMemory 3 GB 1066 MHz DDR3 ECCGraphics ATI Radeon HD 5770 1024 MBSoftware Mac OS X Lion 10.7.4 (11E53) Hopefully someone can shed some light!

I bought 2 crap iMac's off eBay, 1 is the lowest iMac G5 ever made, the otherr is the highest. I the lower shows the 2 green LEDS and no signal for the display. The second is the same. I have given them their respectivly correct memory, clean and hoovered the insides, tried on multiple occasions to clear the Pram, and reset SMU, on both using my Alu apple keyboad. I have put a 250gb he in them , and although it is still an so drive, I just wanna see some screen

It changes color from yellow to green. When I pinch the lower side of my display together, it goes back to the blue background color, but still has a distortion to it.
View 1 Replies View RelatedI 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.

My Macbook pro's display has started playing up. Having green flickering lines which come and go randomly, especially on images with a lot of black. Right now, the lines just disappeared as soon as I connected to mains, to start recharging the laptop. I'm using OS X 10.7.4 with NVIDIA GeForce 9400M.

View 2 Replies View RelatedI am having a display issue with my MacBook (mid-2007) I am getting occasional pixelation on darker colors. The pixels turn redish/purplish/pinkish...If I press on the screen near the Apple logo (on the top cover) and on the lcd screen I can sometimes get the issue to go away. When I plug in an external monitor the pixelation does not show up on the external monitor but will stay on the laptop lcd display. I do have windows also installed and the pixelation shows up in windows as well.... So my thinking that it is likely an issue with the LCD cable or LCD display....

Working in Excel today, I was highlighting groups of cells with color when the entire screen suddenly had a pale grey-green tint. Can still see colors beneath, but everything tinted (not just the Excel window, but the entire display). White, of course, is most dramatic. The Dell monitor beside it is fine.
I've recalibrated color a half dozen times (have always had to do that to get the Dell and iMac screens as similar as possible). It's impossible to get white on the Mac. Rebooted several times, including hard boot, zapped the PRam, ran Permissions Repair and Disk Repair from the startup CD. Installed Temperature Monitor to see if there's a heat problem, but I could not find normal temp values anywhere on the Web, so that was something of a bust. Temps attached below in case there's an educated set of eyes out there....
Ran some online tests, too, for color distortion, dead pixels, that kind of thing, but nothing reveled.
I've been all over the Web looking for some guidelines, but most posts at apple and elsewhere seem to focus on later-model iMacs with the yellow lower screen problem when new (It's not that) or panic screens of wild colors, stripes, and the like. This is just a grey-green tint that covers the entire screen, rendering whites grey-green and colors muddy.
My wife's macbook monitor is destroyed due to happy 2 year old. It won't be worthwhile to replace the monitor and it is not fixable without some expensive work being done on it, therefore I would like to use our TV as an external monitor and retire the macbook to being a mediia computer. I have connected it to the TV, and I see an empty desktop, as far as I can determine it looks like it is treating the TV as a secondary display - that the desktop is extended onto - so I cannot actually interact with the normal desktop. When I try to run things using keyboard shortcuts I hear some sounds of things starting, but I don't see anything on the TV. So what I need to do is to have some way to tell it to treat the secondary display as the primary display.

Anyone ever gotten a green screen? Last time I saw one, the logic board died. I'm hoping that's not what happened here.I was ripping some videos on my MacPro 1,1 (2006) when all of the sudden the computer crashed and the screen turned green. Now, everytime I restart it won't go past it.it's not the motherboard cuz that's an expensive fix!

I'm sure it's an upgrade issue, when I go back to our clone from last week, it doesn't do that! We use QT Pro 7.66. on a MacBook Pro (about 1 1/2 years old) - always perfect results, but now this? No big deal, just a little annoying. It only does this on a few of the movies we've exported out of Final Cut Pro. Can't find the pattern?
