Flickering green in black areas of screen

I have a flickering green in the black areas of my monitor. As if the Enhance contrast is set above Normal in Applications System Preferences Universal Access. Though the slider is still set down at Normal.

It does sound like the XT1900 is to blame. What you see is DVI noise. If you search this forum, you will see that it has been a common problem. If the MacPro is under warranty, then I would ask Apple for a replacement.

The Mid 2010 15-inch MacBook Pro problems are related to kernel panics, so the GPU is still working. In the case of the OP, the GPU has stopped working completely, so his/her problem doesn't belong to the kernel panic problem, so the OP may have to pay. I may be wrong.
Also, the 10.8.4 update won't help as this is a hardware problem, but it's always good to keep OS X updated

Flickering green dots... What's the final answer?

Hi, I jgot in my 30" monitor 2 weeks ago, but ..waited to find on ebay an AGP video card. Spent far more than I should have to get it, and now have flickering green dots everywhere!
The screen is perfect when directly connected to the monitor. When I use a dual link DVI extension I get them. I've changed out the extension and still get them.
I tried all the tricks I could find... blowing out the connectors, taking off of sleep mode, changing number of recent items (I'm not sure what this refers to) from 0 to 10, going into and out of sleep mode, plugging and unplugging, changing resolution and display from 256 - 1000's and millions.....etc.
All in all, something fixed it once! Then they came back.
Frustrating. So... Is there a real answer?
I'd include a photo, but I'm not sure how to add this as an attachment?
I've put a link to my .mac account here:

Thanks in advance!

OK, I think I solved the problem!
The extension I needed was a basic female - female Dual link DVI
Since I needed a male - female, the store sold me a gender converter. I have since bought a dedicated M/F dual link and it's working. I believe that even though I changed out the gender converter twice, it was just not up to carrying the bandwith needed for this type of signal.
The problem is now solved and Altex took back the extension and converter, no questions asked!
I bought the cable through a local mac dealer.
Good luck to all!

Has anyone experience Mac Book Pro screen went alien green and black?

Hi...I was using my mac when the screen suddenly turned alien green and black, I can still use it though (like save the file and so on). It turn alright after you restart the computer, but I'm afraid if something has gone wrong.Does anyone ever experience the same problem? Does anyone know what is wrong with my mac? I start using this computer since November 2008. Cheers!

Update:
I brought it into the Apple Store near my house once. Booted up fine twice. Brought it back, because the green and black vertical lines, and the inversion of colors froze the computer 4 times after the visit. The Apple Genius ran a MacBook Pro NVIDIA graphics card test, which went well until it FAILED one of the tests.
I had the option to have it fixed in the course of a week, but I thought that since it froze only a few times, that I could work through it (I have important final projects coming up), but now it won't start up. I will have to have Apple ship it away to fix it, because they are behind in their repair shop in the store. So, I will be without it for a week.
They said it had something to do with the logic board, which I think is part of the motherboard. So, I am glad I backed up most of my projects' data, as they said they might have to erase data when they fix it.
So, save your files onto external media (HD, flash drive, CDs, DVDs, etc.), and don't let this problem persist; have an Apple Genius check it out, so that you're not in my boat.
I wish you the best in your troubleshooting!

My screen has greens and black lines going down the middle an I can't access anything. What could be wrong? It happened all the sudden.

You're welcome! I feel your pain - both "closest" Apple Stores to me are almost 2 hours away. When I called for another problem under warranty the AppleCare guy checked my zip code and found an AASP (Authorized Apple Service Provider) 20 minutes from me I had no idea existed. They diagnosed the problem (bad bluetooth keyboard) and ordered a new one for me. The AppleCare person will probably use this http://www.apple.com/buy/locator/service/ so you can check it now. And AppleCare could well diagnose your problem over the phone anyway. And I feel certain it wasn't something you did inadvertently.

Iphone 6 while plugged in during night lit up, screen turned red then green then black. Apple icon comes on and won't work for 15 minutes

Just wondering what Apple's stand is on the issue with a flickering and a dark area appearing on imac 27"screen - forums seem to indicate this is not uncommon - and happens through normal use - so should be subject to repair (Sale of Goods Act - 6 years)

We are just users like yourself. If Apple has stated publicly about the problems you mentioned, it will be listed on their website and/or in one of their Knowledge Base Articles.
I have a 27" & do not suffer from such a problem. You should keep in mind that these are technical support forums. Generally, the only people posting here are those with problems. The thousands/millions without problems don't ever come here.
Think of these forums as a hospital emergency room.

Black areas are showing up as green

Since I upgraded to Firefox V:8 some of the images show the black areas (background, shadows, and the like) as a bright green. If I change to the IE engine, the problem goes away. I've messed with disabling the add-ons, without any repeatable fix. Sometimes, disabling one of them will fix the problem, until the next day, when things are messed again(?).
The problem seems to link to JPEG images, but I am not going to guarantee that just yet.
http://ashleymichelew.blogspot.com/ is one place I've seen the problem.

That can be caused by a problem with the color profile for your display monitor or color profiles embedded in images.<br />
You can disable color management to test that.<br />
You can set the pref gfx.color_management.mode to 0 on the about:config page to disable Color Management.<br />
You need to close and restart Firefox to make the change effective.

Replacement screen shows all Blacks are instead, Super-Blue's!

My original Dv7-3065dx screen went blank with the back-light still going. Every so often, it would work for a second, then go blank again. so i changed the cable and screen. The new screen worked, except now all the blacks, are super blue! So, of course i thought i got a bad screen, so got another one, but this time it seemed even worse! Upon turning it on, the windows symbol, even steaked blue across the screen, then same thing, all blacks, super blue!
I do want to mention, just in case, the fact that i purchased after market screen, from Amazon, for like $85, that had a converter cable on the back running from the left side connect to the right side connect, so i could connect on the right side.
Could these cables on the back of the aftermarket screens be causing this super blue problem?
I have check connections, to make sure it is pluged in like it should be.
External monitor works fine.
Also, i have already dissassembled the entire laptop, and cleaned the fan and re-thermo'ed the cpu! Runs alot cooler, screen works, but all the blacks, are still super blue, with occasional blank screen period.
What's next?
Anyone?

OK!!!!!!!!!!!! I got my 3rd screen in today, from the site you told me about. I got the one w/o the converter cable on the back of it. AND GUESS WHAT?????????????? IT FRICKIN WORKS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
AMAZON SELLS CRAP FOR SCREENS!!!!!!!!!!!!!!!!
I almost kept the 2nd screen, because i thought there was no way it could be both screens, BUT IT FRICKIN WAS!
Sorry for all the caps and !!!!!!!!!!!!, but i am happy and pissed at the same time, because of the headache AMAZON caused me!
Anyway, i am hoping you also tried the one with the cable on the back, so if you did, your problem should be fixed with this also!
Let me know.

MacBook Pro continues to reboot then shows main screen with flickering green and white lines then restarts again what the heck is wrong with it?!

Black Area taking over screen

So whenever I press play in logic express this huge black area takes over the screen behind the play head and moves along with the playhead. I don't know what to do to get rid of this huge black/dark display.

It's virtually the same program these days.
It would help if the OP posted the version he/she was using and what updates are installed.

Poor Picture- Blacks are Green

I have a Dynex 32" LCD and any black areas or shade of hair have a very noticalbe green tint to them. I have tried to adjust this out in the picture but cannot. Any suggestions?

The only thing I can think of is to keep adjusting or have the TV calibrated, now i dont know how willing you be to do that since the price of it is probably pretty high compared to what you paid for the TV but is an option.

My iPad 2 with iOS 7 touchscreen is no longer responsive, although date/time is current as are off screen buttons. Tapping the screen merely produces a rectangular border around the tapped log in digit. No 'black to white' registers on the upper 4 dots

Excuse brief text to above due to input limitations in original input field. I'd be grateful if anybody can give me any help to recover the situation. Thanks.

Triple tap the home button

Screen flickers and goes black on boot up.

Have an older white MacBook that when I boot up, screen flickers and goes black, MacBook does power on.
Any suggestions?

I am seing a similar issue with a 13" White MacBook.
Powers on ... chimes ... then screen goes blank as if the machine has gone to sleep. Hitting the Return key or the power button wakes it again, but only for two seconds ... and repeat!
Any help gratefully received!
