Hardware :: Flickering Light On Right Bottom Of Cinema Display
Nov 26, 2007
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.

Just a quick question, been searching for an answer the last few days, but been unlucky...I'm just curious, why has my Cinema Display standby light stopped glowing (from dim to bright then back again)? I'm sure it use to do this when i first got it - the display itself is only 6months old

after color balancing a clip I get a flickering border on top and bottom of my clips, visible in timeline and also after rendering. It's easy to see in this clip (starts around 15 seconds in): URL....
If I remove the color balance it will go away. I wonder if it has to do with the source clip being in 1080i instead of p. The preceding clip is also color balanced but is in 1080p. It's less noticeable but sometimes still there when other color correction is invoked. I'm using a late 2013 Haswell 27 in iMac with 8gb ram.

iMac (27-inch, Late 2013), OS X Mavericks (10.9.4)

I am actually trying to decide if to get the old 30" cinema display or not.I'm a graphic designer and my fear is that apple will never make a matte display...Here in Italy it's still sold in the apple store. I have the unibody macbook pro, and so I've been reading through reviews now for a week ... my biggest concern is the dual-link dvi adapter... I still see posts (August or September 2010) with people experiencing issues, even with the firmware 1.3!I wanted to ask you people if I should go for it or dig the 27 inch even though it's glossy... I have a few people in the office (also graphic designers) working on iMacs and got used to the glossy.

I just installed 4x1gb OWC ram onto my top riser, adding onto my previous 2x512(dimm 1&2) + 2x1gb setup (which is now on my bottom riser). My previous setup had no problems and OSX detected the ram just fine but now with my previous setup on the bottom riser, OSX only detects the top riser with the new OWC 4x1gb ram. My former setup now displays a red LED light on the bottom riser.

I'm not sure if this make sense, but I'll do my best. (I'm a Mac newbie as of four days ago, and generally loving it)
I've somehow set up my display to have an appearance of a folding effect emanating from the bottom of the screen. This effect also shows through any open windows, which is annoying and distracting. If anyone knows what I'm talking about and how to turn it off, I'd appreciate it. I tried taking a screen grab, but the effect doesn't show up on it.

My 2010 13" Pro seems to have some blue/magenta light leaking from the bottom of the screen. This is only visible with the brightness turned up and against a black background (i.e. when watching a letterbox movie). It's quite different from the "typical" white light leak that I've witnessed on other lcds. Would this be "normal"?
Also - and this may seem like nit-picking - but my caps lock key feels a bit flimsier than the rest of the keys. Again - is this "normal"?

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.

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.

The title says it all really... Quite a simple problem that I can't find any answer to!
I've hooked up my 30" Apple Cinema Display to the new iMac 27" and the highest resolution I'm getting as an option is 1280x800... The iMac correctly detects the ACD as a Cinema HD display but limits my resolution. Why oh why?!

I own 23 and 30" Cinema Displays. I like the 23 because everything is larger and easier to read than in the 30". I mostly work in Logic and love that I see lots of things on the 30" but the 23" is much easier on my eyes.Is there such a thing as a display with 2560x1600 (like the 30" Apple) but that is LARGER than a 30 inch so I can see everything bigger in Logic??? Maybe a 34 or 37"? Did a search but haven't come up with anything other than other 30" displays.

I am looking for a display to use with my Powerbook G4 12". I am in love with the 30" cinema display, but according to technical support today, my setup is not compatible (supposedly, but the person on the phone didn't sound to sure). I have a mini DVI, but the 30" requires a dual DVI. I think the 23" display requires DVI, which I can attain with an adapter. Does anyone have suggestions for what I can use with my computer? The bigger the better for me. Also what do you think of the older (plastic case) apple displays?

Purchased a brand new 27" i7 imac a few weeks ago, display is awesome!!! I was using my old 28" LCD monitor from my PC and running dual displays on the iMac. The 28" LCD monitor annoyed me a bit because i could not get the same color/crispness/brightness that i got from the iMac. ( also it has a Matt screen and i am more into the glossy screens ) So i found a used 24" cinema display locally. Paid 600.00 and it came with 2 yrs of AppleCare. It is only 7 months old ( still have 5 months under orignal warranty ) Got home, hooked it up and it had a "hint" of yellowness to it, It wasn't a exact image of my iMacs display...I tried to calibrate it also, but it still had just a HINT of yellowness....Nothing at all major, but enough for me to be annoyed with it.

I have a 2008 Mac Pro with ATI Radeon 2600XT and a 30" Cinema Display. I am considering buying a Wacom Contiq 24 HD screen/tablet and would like to know if the Radeon 2600 will drive both or will I need a second graphics card? If so, do I buy another 2600 or can someone suggest something suitable?

I am thinking of updating my home studio setup which is currently running a Macbook pro 13" 2.26 with 4gb of ram. I was first thinking of upgrading to an iMac with a 3.06Ghz processor and 27" display. However, I now think I might be ok staying with my MacBook and upgrading to one of the two displays;- The 30" Cinema display- Or the 24" Cinema LED displayAt nearly half the price I am leaning towards the 24" display. I am using logic and ableton. What does everyone think and anyone had any experiences running logic and or ableton with a MacBook and display.

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.

As you can tell by the thread title I've got one of the latest model iMacs and I'm running an LED Cinema Display as a second monitor. When it gets to the late hours I like to watch some movies on the Mac so I figured the Cinema Display would be a nice addition to do the job.
Now here's my issue: if it's late and I'm watching movies I tend to not have any lights on, but having one of the displays on means having both of them on, what I'm wondering is if it's possible to sleep one display while allowing the other to stay active so I can watch the movie without the light from the other one distracting

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.

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.

Right now i'm using Apple Cinema Display 20" that i bought at the end of 2005. You know, the aluminum one. But i've taken interest in one of those LED Displays, especially the 24"...
Now, i've read that the LED Display uses glossy display compared to the Cinema Display? Also, it's completely my own opinion, but the older Cinema Display seems to be looking more nice also having one-coloured.
The technical specifications are in favour of LED Display of course, but taking into account the glossy display, less attractive design and so on... Which one would you get?

I know that the general consensus here is that the Mighty Mouse is a piece of shit. That notwithstanding, I'd appreciate posters refraining from engaging in further elaborations on that concept when replying to this topic (i.e., no comments like "Buy a new mouse," please).
At any rate, I purchased a wireless Mighty Mouse about a month ago and was very happy with it until the batteries apparently died. One day the pointer simply stopped responding and the green light on the bottom of the mouse was flashing. I replaced the batteries and the mouse resumed normal operation. Then, a few days later it happened again. I have yet to re-replace the batteries and have reverted to using my now eight-year-old Logitech dual-optical mouse (possibly the finest peripheral I have ever owned). Has anyone else encountered this issue?
Is this mouse having internal hardware or software issues or is it normal for it to devour batteries at this rate? System Preferences says that Bluetooth is maintaining the connection properly, so I am ruling that out as an issue. I would just say to hell with it, and use my Logitech mouse full-time, but my wife hates it and I payed seventy goddamn dollars for the Apple product.
