Pixel Artifacts on screen

I am having an issue with what I think are Pixel Artifacts on screen when I roll the mouse around on the screen. Its also evident when I click on certain things on screen as well. This all started after installing Leopard earlier this week for the second time. I first put Leopard on my computer back in August 2008 and didn't have this problem then. I read something about resetting the PRAM. Should I do that to fix this issue? It's annoying because if I am dragging the mouse across the screen its almost like the pointer "arrow" will grab on to words or whatever and it will be a trail of the same word across the screen or sometimes its just a small box or square.

You can search around the forum for "pixel artefact". There can be many different reasons. Here's [a thread|http://discussions.apple.com/thread.jspa?messageID=8631126&#8631126] with some suggestions, including how to zap the PRAM. For the user in that post, the diagnosis was that the logic board needed to be replaced.
Hope it helps.

2012 macbook pro retina display artifacts on screen when using onboard video

2012 Macbook Pro Retina Display artifacts on screen when using onboard video.
About a month ago I've noticed these strange artifacts (blocky pixelated looking) running vertically down the screen. It first started when using Safari. Then it started to happen all the time. I turned off the auto switch video in preferences, which I'm assuming forces the computer to use the separate video card and the artifacts go away.
On top of that issue I also have had the ghosting issue.
Anyone else have this problem?

artifacts onscreen could mean a faulty gpu. You said by forcing it on inbuilt gpu you do not find this issue highlights that. Do take it in to apple for service and also tell them of your ghosting issue.
There are a few retina owners who have faulty gpus.

White Pixels on Dark Screen

I purchased the 30" Mac monitor and noticed that when the screen is black, there seems to be white flickering pixels across the screen. It looks similar to interference or slight static. Does this mean my monitor has a problem?
Thanks for the help.

I have a line across of blank pixels across my screen

There is a line of pixels on my screen that goes black when the backlight is on but when the backlight is not on it works just fine. I did not drop it or anything, I just plugged it in to charge and when I went to disconnect it the line of pixels did not work when the backlight was on. What is the cause of this and can I fix it? It is a 30G 5th generation video Ipod.

I too have something like this on mine. The size changes everytime I turn it on. Using it in the car (with Alpine adapter) it's always charged. When I plug in the iPod, it will be small. When I remove it, the size is often bigger.
I'm looking into replaceing the desplay (unit is out of warranty).

I have da stuck pixel on my screen. On my iphone5. What can I do?

Hi! Sorry for the late reply.
You could go back to Verizon, though it's highly likely they might send it away for repair. If you go into an Apple Retail Store instead they tend to do everything on the spot.
Not entirely sure with Verizon's options (Im in Australia) but can only give it a try

Pixel artifacts with 9600XT

Hi,
I just upgraded my FX5200 to a radeon 9600XT. I have two apple Monitors connected. The adc Monitor (15") works fine. The dvi Monitor (20") has pixel artifacts when I drag windows arround. They go away when I reopen it or make a selektion. But the artifacts come again when something is in motion, like draging or video.
I tryed AticalliratorII and did a Combo Update again (10.3.9 and 10.4.8) to get the latest drivers but without a solution. Does anyone have any idea?
Thanks

Ok,
I played a bit arraound and if I disconect my 15" Monitor (ADC with extension cabel) the dvi output works fine. Now I have to find out if the extension cabel is the problem, but it worked fine with my FX5200. Strange.
But anyway, if someone has any suggestions feel free to post.
Thanks

Photoshop CS6 selection, shape, and text is causing colored artifacts on screen

The Photoshop CS6 (13.0.4) selection, text, and shape tool causes colored artifacts on screen. I'm running on a retina Macbook Pro updated to the latest ML release. I have disabled GPU acceleration. I have also tried starting Photoshop with no plugins but this does not help.
I have created a video which shows the phenomena
http://www.youtube.com/watch?v=VG5ayC3WmKA

SOLVED. After two days of intense debugging I've identified the issue as an interaction between the ICC color profile, integrated GPU, and Photoshop. The ICC profile was created with an i1Display Pro using the i1Profiler software. The issue occurs when you create the color profile using the LUT setting. Creating a profile using the matrix setting seems to be ok. In summary, these are the specific conditions that cause the issue (for me):
1) Using a color profile created with the LUT setting with i1Profiler and i1Display Pro
2) Using the integrated GPU (discrete GPU is disabled in Photoshop Performance setting)
3) Running on Photoshop 13.0.4 (13.0+ all have the issue) on a 15" Macbook Pro with Retina display
Creating a new profile with the matrix setting OR enabling the discrete Nvidia GPU will also make the artifacts go away. The integrated GPU using the LUT based color profile does not seem to have any artifacts in any other photography and video editing software that I've tried so Photoshop is playing a role. The nature of the artifacts also change from Photoshop version 13.0 to 13.0.4. For example, in Photoshop 13.0 the Marquee Tool has no issues while 13.0.1+ has artifacts.

Column of bad pixels on LCD screen

I have a 2 year old Macbook and a column of pixels on my screen, roughly 1/6 of the screen width, are flickering. I now know that the screen is divided up into six sections, each with it's own flexible connector. I think the contact for this connector is at fault but I'm not sure what happened to it or how to fix it. Has anyone else encountered this problem or know how to fix it?
Thanks!

I am having this SAME problem. My column is just left of center... Its so annoying.
Any help is greatly appreciated.

Dead pixel in my screen? What will apple do?

It seems that I have a dead pixel in my screen. I have a keen eye for them as I have had to replace 2 LCD tv's because of this. Even though it is'nt a huge deal I would like it fixed. Any idea on how apple will handle this? Just replace the phone I'm assuming. Anyone have this problem also? What was the outcome?

So in other words what your saying is, there is a standard for how much your screen has to "not work" for them to care? And I read the pixel anomalies article by apple and it seems like a pretty BS way of getting out of replacing a phone. I talked to my buddy who is a TV salesman and he said it is rare to have this happen with TV's and when it does they replace them. Seems like apple should do the same. Hopefully I can get the issue resolved because this is
not the only problem. When I am in the recent/contacts section my screen doesnt work or jumps around (doesnt select where I put my finger, goes random).

Dead Pixel , or uneven screen brightness test

Hello
I will get my new Imac monday.
Could you please tell me how can I check the screen for dead pixels or uneven screen brightness issues?
Thank you fpor your help
Please when you explain, take in consideration that I never used a mac before,
I am a switcher
Many thx

Normally you will see any stuck (colored) or dead (black) pixels right from the get go. Many times stuck pixels will unstick over time or by running pixel fixers.
example: http://www.jscreenfix.com/basic.php
In the unlikely event that you have any dead pixels, contact Apple, your local Apple Store or Apple Service Provider there really good about making things right.
All computer displays will exhibit some sort of unevenness and or back light leakage, but most folks don't notice or worry about it. Unevenness can be seen using a solid light gray or light blue back ground and backlight leakage can be checked using a black screen.
+Just slap up your favorite photo's or wallpapers on the desktop and move on.+

1 dead pixel on the screen

I seem to have a dead or stuck pixel on the screen. How do I know if its dead, or if its stuck? Do dead pixels look different from stuck pixels?
Im not to bothered about it as I can hardly see it and I struggle to see it, but it is slightly annoying that you know its there. It looks turquoise colour, but when I put some black over it on the screen, you cant see it.
Also, I have downloaded the stuck pixel fixer and run it for about 20 minutes, and it doesnt seemed to have done anything.
Does anyone suggest what to do? Also, does apple have a pixel policy? Like I said im not to bothered by it, but when you know its there it can get a bit annoying. I have to really look for it to see it though.

Yes thats what I was thinking. Like I said im not to bothered about it and I can hardly see it, but might give them a call and see what they say. Its not acually to bad. I have dead pixels on other things before and they have been much worse. It must be because of the resolution of the screen or something.
I have to say, the one thing I hate the most and is the most annoying thing out of all technology for me is a dead pixel, esspecially when its right in the middle of the screen. This one is just at the top where the program menu bar is, so its not to obvious. Infact, its probably the best place it could have happend really, if it were to happen at all.

Pixel dot on screen. (please help)

I 've had my imac less then 1 month and just notice a small red pixel dot on my screen. The imac isn't returnable anymore.
What do I do?
Thanks!

I've noted a little fix I think may be work in a another topic- basically, if any of you are familiar with the PSP, there have been some fixes for stuck pixels, usually with a 70% success rate.
I've created a similar fix for the Mac called rapidFire. rapidFire is a simple QuickTime movie, that if successful, should eliminate any "stuck" pixels on your screen. By rapidly displaying red, green, blue and white colors on your screen, the capacitors that control a "stuck" pixel should begin to work properly again.
This movie is based off a popular solution for "stuck" pixels on Sony's Play Station Portable. Users report a 60-80% success rate with these units. While I haven't thoroughly tested rapidFire, it should not cause any damage and will not void your Warranty or Apple Care Protection Plan coverage. That said, it's offered AS IS, with no warranty implied.
Download rapidFire here: http://chris.macteens.com/RapidFire.zip
You could also try gently massaging the area where the stuck pixel appears to be, but you must be very gentle (yet applying firm pressure) when doing this.

Dead pixels or scratched screen?

I just bought a video ipod about a week ago. After 3 days of listening to music I watched the first video and noticed that there was a patch of pixels on the screen that looked discolored, almost like what it would look like if there was water on the screen. It's really distracting when I'm trying to watch a video. I thought they could be dead pixels, but when I tried to exchange it at Best Buy, they wouldn't take it because they said the discoloration was due to the small scraches on the screen. I knew that the screen had gotten a little scratched, but I didn't think it would distort the picture that much!
Am I wrong? I would hate to think that my $300 ipod could be affected by tiny scratches that much. Is it possible to have the plastic front replaced?

but when
I tried to exchange it at Best Buy, they wouldn't
take it because they said the discoloration was due
to the small scraches on the screen. I knew that the
screen had gotten a little scratched, but I didn't
think it would distort the picture that much!
It wouldn't. A few surface scratches - which are actually on the case, not on the screen itself - don't cause that amount (or even that sort) of distortion; you'd have to smash the front of it with your fist or sit on it to cause that kind of damage.
Best Buy is notorious for trying to prevent customers from making legitimate returns. How did you pay for the iPod, cash or credit card? If you used cash, you're probably at the mercy of Best Buy, but if you used a card, just call the number on the back of the card, tell them you were sold a defective product, the seller won't let you return it, and you want to file a complaint. The customer service rep will explain the details to you; you'll have to print out a form, fill it out and snail mail it in to the credit card company, but it's worth it. (Do this soon; by law you only have 60 days to file such a complaint.) The credit card company will investigate, and if they determine Best Buy sold you a defective product, you don't have to pay for it. That sort of leverage, once you take advantage of it, usually leads to the retailing caving in to the consumer rather quickly.
Even if you did pay cash, you should go back to BB anyway, ask to speak to the top manager, and demand a replacement or refund. Be polite, but be firm, and keep asking for higher and higher supervisors until you get what you want.
By the way, in the future, admit to nothing whenever you need to return any product anywhere. I'm not saying that if you spill a beer down the back of your brand new TV that you should try to take it back and lie about the obvious cause of the malfunction. But if you put a minor scratch on something that has nothing to do with the problem you discover soon afterwards (as is likely the case with your new iPod), then take it back and if questioned, say "it was like that right out of the box" and stick to it. As long as we live in a world where employees at places like Best Buy are under orders to do everything possible to stop legitimate returns, you're under no moral obligation to hand them a ready-made excuse to refuse to take the item back.

IPhone isn't using all pixels on the screen?

Hi All
About one month ago i finally pulled myself together and bought myself the iPhone (great phone ) however, i just looked closely at the phone today and noticed one thing. When i am looking at the border of the screen (right before the "real black" it is, as if there are a row of about 3 pixels around the screen. That aren't used. Is that a faulty phone, or is that normal? (i will try to post some pictures when i get home later tonight)

yeah i still think its a new problem for me...i didn't notice it for the first 4 months i had the phone and then all of the sudden i did a month ago...i just don't care enough to send it to apple and be phoneless for a few weeks
