MacBook Pro :: Why Does Display Keep Flickering With Dots
Jun 4, 2014
It used to stay like that until either I'd move my mouse over the area, scroll the page up or down, or refresh. It only seemed to happen in browsers, not in Finder or anything. It's the worst when watching videos on YouTube or any kind of flash video. But works fine on Netflix. I say "used to" because the above screenshots are from July 2013. I sent my laptop away to Apple but they were "unable to reproduce the problem." I figure they just left the laptop open and waited. You have to use it like it's YOUR laptop and then it will happen. Anyways, now it's happening more often. Except it's just a flicker. Over and over again. I could record video of it, if necessary.
So, I'm running 10.9.3. I'm not sure what other information is needed. But my computer is up to date. I don't have warranty. I just want to know what is causing my computer to do this.

My homeroom teacher's 14 inch G3 iBook's display has started displaying everything grainy. There are little dots everywhere on the display, and it is annoying. The head IT person at school is stumped. I am not sure of the exact version of OS X, if it might be a software issue. Could it be a sign of logic board failure?

There are random black horizontal lines, constantly on the screen.When I leave the setting of 1280x800 (default), the defects disappear, only small distortions, which makes me think that the error can be corrected via software update. As the Lion was on 10.7.3, I upgraded to 10.7.4 to see if improved. But the errors persists.At the end of the video, the lines are most striking, becoming impossible to work.

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've got my MBP that I've had for about 4 months, the thing is. It just recently started to have screen flickering issues. I'll be sitting doing w/e as usual and all of a sudden the display goes dark, almost black, for a second, then comes back up again. I have yet to find any trend in when this is happening, but it is definitely happening on battery as well as plugged in, but it seems to be getting worse.any one have any idea what this could be, something I can fix on my own, or should I take it in?

I have a 28" inch display attached to newest version of Air. Works ok except when I have a full screen on plain dark grey background, then I see a waviness or flickering effect. Like the dark grey in Iphoto background. Other than this, the other colors seems ok. Pictures are fine, even when dark. Maybe there's a slight flickering with dark blue. Any explanations for this.
using mini display port to dvi. Tried with a friends dual link display, was a little different, but still unstable looking in dark grey when it fills the screen.
Could it be just what it takes to make this color, or the Hertz, which is 60. Other than this, no problem with the screen.

I have a new 17" uMBP that I've owned for just a few days. I noticed yesterday that while I watching a video that i had strange green/red lines (horizontal) appear across the screen and flash/flicker. I freaked out and closed the lid, putting the unit into sleep, and opened it again and it all stopped. Today, I was using it again as usual, on firefox/etc. when it started happening again. Horizontal lines across the screen, the entire display flickering and screwing up and finally going black. I don't know what's going on, but I know this definitely isn't supposed to happen. I took a screenshot during the flickering/lines/etc but the screenshot came out perfectly fine unfortunately. I'll try and get it on camera next time.
I have all software updates installed. I tried resetting PRAM. The flickering I'm talking about isn't minor, it's actually absolutely horrendous and the computer is completely unusable when it's going on. It ultimately leads to a black screen. Anyway, this is all on the 9400, and I have no idea what's going on but I definitely know this isn't supposed to happen. UPDATE: I booted into Windows via bootcamp and it STILL happens. I also connected it to an external display(which works perfect), which leads me to believe that it's 100% a hardware issue. I'm taking it back to the apple store, enough said. This is my first Mac and I can say I'm definitely not happy to be having such issues with a $2500 machine.

Our display flickers on one side and has multicolored vertical bars running down the left side at best, or the whole screen greys out over the top of the graphical display, is physically no longer fully attached on that side near the hinge (you can press it down quite a bit after it has been closed), and the aluminum clamshell seems like it's warped. The bottom access panel has become no longer a smooth fit - it sticks up a few millimeters at the gap instead of being flat. We used to be able to hold the back left side and the screen would work, now we have been sitting it on a wooden structure with a back support and pushing it against that so we can see the screen for the past year or two. Now the flickering vertical bars are getting worse and the wooden support doesn't always work, and as an added bonus, the trackpad recently stopped working (it no longer 'clicks' and acts like it's constantly pressed down, so we have to use an external mouse with it). It's pretty frustrating because we've babied this thing (it's never been dropped or abused and has only left the house like twice, and one of those times was to take it in to see about this very problem!) and it seems like it's a manufacturing defect, but of course we never had AppleCare and this powerful expensive beast is now a desktop computer with a super hard to see screen. I've been told we need to pay $400 to get a whole new clamshell.

I have a Late 2011 MBP, just recently I also go an Xbox and wanted to hook it up to my external display that I have been using for a long time with no issues. I went and bought this: URL....to be able to easily switch between the two inputs. The xbox works fine, however when I view my Macs input the screen flickers a static image very frequently.
I know what you're thinking, it's probably an issue with either a cable, or the device. But when I boot into Windows via Bootcamp with the same exact setup, there is no flicker at all. The display is a dell s2440L, the HDMI adapter is a rocket fish.
Here are the troubleshooting steps I have tried: Resetting PRAM/SMCChanging out HDMI cables on both the Splitter output, and the inputs (I tried 3 different cables on both the inputs, and outputs.)Downgrading OSX to 10.7 (And then went back to 10.9)Lowering the resolution on the monitor (Lower resolutions flicker just as much, if not more.)Resetting the splitter by unplugging the HDMI cord powering it and plugging it back in.and of course, plugging my computer into the splitter input that the Xbox works fine on, as well as taking the xbox one out so the computer is the only input on the splitter.
Like I said, the Xbox works fine, and even the computer works fine in Windows, but whenever I boot into OSX my screen flickers with this static. I should add, the display works fine when not connected to the splitter on OSX.

Got a bit of a wierd one. Apple 22" cinema display (the old style). Running from a mac pro with a ATI radeon 1900XT graphics card. Have 4 operating systems running, all were working perfectly until last night. Leopard works great - no problems, as does Tiger and Windows XP running boot camp. What does not work is Vista x64. It was not installed with compatible bootcamp because x64 operating systems are not supported yet. It has been running fine for months though? I also run a small dell 17" TFT off the same graphics card and no problems with that. It defaults to the main desktop on starting up vista, but only in vista. And I get this fast flashing light - about 2 every second or so - regularly. No amber lights and no groups of three.

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.

I have some strange colored dots on my screen that will not go away.
The weird part is that they are not stuck in place but seem to be shadows that are not coming through the right color.
I am new to macs so if someone could tell me how do take a screen shot I will put it up so you can see.

I bought a Macbook pro 13 inch today. I noticed that there are small black dots (maybe small puncture holes) on the top of the lid - about the size of a dead pixel.

I have this issue since a year and never had seen it around on mac forums. So when I play a movie or even grabbing a window around the screen these tiny green-blue dots appear and disappear randomly, sometimes they line up vertically.
The smaller is the movie size playing in quicktime (even in youtube) the bigger are the dots. The good thing is I see them while working with pictures in photoshop, but they don't affect the picture quality when I save them in jpg or other formats.

Before yesterday, when I opened a program, such as Safari on my mac the white dot would appear below it. When I turned on my computer this morning the white dot did not appear under any program i opened. I have safari and itunes open now and neither have the white dot below them. Finder does have the white dot below it, but none of the others do. Its not like it needs to be fixed, but I just find it anoying because im used to the dot being there

I have a Macbook Pro 2.2 Santa Rosa Rev. D model. Recently I have discovered gray dots appearing along the top of my screen.
A few at first, but masses growing are growing rapidly. In the past 3 weeks the problem has started to spread to both my right and left edges as well. Under different viewing angles the dots sort of dissapear. The dots are not uniform in size or pattern.
I have a slight feeling that this has to do with my NVIDIA 8600GT graphic card.
I read tonight that that specific card was reported faulty and thousands have had problems and have had to get their logic boards replaced.
I also read that Apple extended their warranty for this specific reason.
Anyways, the dots are increasing and it's worrying me as I am not sure if this will be covered or not.

I have a 2009 2.53ghz 8gb 500gb 7200 macbook pro, running latest version of snow lep 10.6.4. It's been running fine since I got it last august, now today I started it and I get the blue screen that seems to refresh itself with a slight flicker every 10 seconds with a new blue screen with the spiraling activity dots. I tried booting from a disc, and it nothing changed. I tried booting in safe mode and it the bar would fill up, then it goes right back to bluescreen. I don't have a screwdriver on me, so I can't take the battery out.

I just bought my macbook pro 13 inch about a 40 days ago and I have just noticed two small black dots on the on the bottom of the screen near the left side of my dock. I have done some research and they seem to be "dead pixels" They're really small but for the price I payed i didnt expect any problems. What are some suggestions to get rid of them or if i should contact tech support? Here are two pictures of the dots: They kinda change colour when i move my head around.. Not sure if theyre dead pixels or not.

Simple navigation question as I am new to Mac and suffering from PC withdrawal anxiety. When I expand my browser window fully to expanded, click on the arrows in up right, the three resizing dots on the left side disappear. Any way to keep them in place?

I see red dots all over my screen! What it is happening!? What I can observe is that it happens where there are dark colors. I see them at pictures in Facebook, I see it in iTunes.

We cannot log into our 2010 iMac OS X. The wireless keyboard is registering each key stroke as 1-5 dots (cannot see letters as it is the password login section to access the desktop). The delete key does nothing. The left / back arrow key addes more dots as does the front arrow key. The only way to get out is to cancel out so we are stuck.

Does your screen flicker too, when you watch this pattern ?

My white Macbook, the one i'm currently typing on; the screen keeps flickering. 've uploaded a video taken from my cell phone of the screen flickering. I love my white macbook but the screen keeps flickering until I keep adjusting the angle of the screen. Some days the screen flickering is minimal and I'll adjust the screen easily with minimal screen flickering. Other days i'll be adjusting for a few minutes until I can get it at an angle where the screen doesn't flicker.Here is the link of the screen flickering: [URL]I've noticed there is less/to no flickering at all the closer I adjust the screen downward, i.e., the closer it is towards the macbook itself being closed.
As for the Macbook itself, it was purchased in December 2006 and have had AppleCare since. In June of 2007 I took it in to Apple since I noticed the screen flickering very minimally only when the screensaver came on. I was then told a small soda spill was on the logic board and AppleCare would not cover it, though I was still covered regarding all cosmetic repairs, aside from that soda spill. It hasn't been till the past 2 months the screen flickers heavily and I'm just sitting at my desk adjusting the screen until there is no flickering so I can get my work started. I was considering selling my Macbook for anyone that wouldn't mind the screen flickering but i've upgraded this Macbook with a 500 GB hard drive and before attempting to sell it i'd rather fix the problem myself.
Everyone, I'm all ears. I'd love to fix this problem. If it means completely voiding my AppleCare warranty and opening up my Macbook, so be it. the warranty expires in 6 months anyway.
