  • Why is my 24-inch LED display flashing black (and sometimes scrambles) every few seconds?

    I have recently upgraded to a new iMac: 3.4 GHz Intel Core i7. 4 GB 1333 MHz DDr3. AMD Radeon HD 6970M. 1024 MB. Mac OS X Lion 10.7.4. I have it attached to a 24-inch Cinema Display.
    Before I switched to my new iMac, it would blink black a couple of times a day. This was going on for a LONG time, but was not a big deal. However, now that I have switched to the new iMac, it is every few seconds. And it has now added the "scrambled" screen to it's repertoire. Fun. And, as I am typing this...it just went black and has not come back on.
    I've read a few threads on this happening, but haven't found any substantial evidence as to what is causing this. It's beyond annoying. Has anyone learned anything new?

    Okay. Murphy's Law. As soon as I posted this, I found an answer (hopefully!). My situation fit the criteria at http://support.apple.com/kb/TS4045?viewlocale=en_US and I installed the update and so far, so good. I'll keep you posted.

  • 20 Inch Cinema Display Went Black

    i just rebooted my mac mini that is connected to a 20 inch Cinema Display and the monitor never came back to life. The screen is totally black and the firewire, USB and video cables are plugged into the computer fine. When I look at the computer on Remote Desktop from my laptop i can see that the mac mini is fine. i can also see that when i hit the on/off button on the display that it prompts the shutdown/restart popup on the mac mini so it is communicating with the mac mini. i have also plugged the display into my PB and again I get the shutdown popup when i hit the display's on/off button. is there anything to do to bring it back to life or is it dead? its not even a year old.

    Hey,
    Same problem happening here, You described it exactly. Even the magenta box. Mine also happens most in the open windows, not when the desktop. I am trying to figure out when exactly it is happening. The third item I have issues with is that blocks of data are 'stuck' in a genie expansion like motion so it is blurred and dot displaying in that 3x3 inch square section. Could have something to do with refreshing? Sometimes I notice the window will fix if I manually resize the window.
    Hope this helps any one who is trying to help us out.

  • 27" display flickering blacked-out over-heating

    One of our cinema display is constantly blacked-out or flickering.  And, it feels much warmmer than the other two next to it.
    Does any one have similar issue???  Thanks!

    That is not normal nor acceptable behavior. Take it to Apple Genius Bar right away.

  • Resolution Problems with 30-inch Apple Display and my new iMac

    I'm not very good at computers, so I could use some help. I just bought a new iMac 24-inch, 3.06 Duo and I have an Apple 30-inch display I had connected to my MacBook Pro. Now I can't get a resolution better than 1280x800 and the cinema screen flickers a bit. I bought a mini-DVI to Dvi Adaptor. What else am I doing wrong? The display is enormous on the cinema display and I need to use that for my photography. Help anyone, please?

    i'm not sure if you area sking this... but it seems like the info about the iMac is not to do with the problem, but your problem is with the 30 inch screen and the macbookPro?
    If you are asking about a macbookPro plugging into the 30 inch screen, these should be able to run full resolution from what i remember,
    you need to check that you are NOT trying to run mirrored desktop as this will limit the resolution to the maximum possible of the smaller display (your macbookpro) which will mean you can only go up to 1280x800 but if you uncheck the 'mirror display' option you should be able to set independent settings for each screen.

  • Apple display occasionally don't wake from sleep

    Hey guys,
    I recently bought a macmini (2011) and a apple Thunderbolt Display. All works fine but a couple of times my display won’t wake from macmini sleep when i click the mouse or keybord! I power-cycling the monitor (unplugging power, waiting a few minutes, plugging back in) and worked for the first time. But in the second time not work… I reset the smc from mac mini and wake up again!
    Is this is normal to happens several times??? It indicates some kind of problem in the video card in macmini or hardware problems in the display?
    Many thanks

  • Second screen blacked out when full screen with dual displays

    I have a MacBook Pro connected to an LCD display. I use both screens. When working from home I'd like to have my local machine showing on the LCD monitor and my work machine showing in the MBP screen. I can do this, however I can't have the work machine in full screen mode because ARD blacks out my main LCD monitor. This frankly drives me nuts as there doesn't appear to be a preference within ARD to change this.
    iTunes does the same thing. If I want to watch a video full screen in one monitor it blacks out the other. C'mon Apple, Quicktime doesn't do this and has a preferences tab just for display settings!
    Does someone have a suggestion, work around, or want to point me to what I might be missing to solve this issue?

    I understand what you are doing, but when you are running as full-screen the second display is blacked out because your making your station only the target at that moment. You are telling ARD that you want nothing to do with your Admin station. Also because the target doesn't have a second screen, your is blank. This avoids any confusion as to what screen belongs to what machine. ARD is working as it was designed to.
    iTunes does the same thing to hid extra screens that are not part of the presentation so they don't detract from the show.
    With your Observe or Control in Windowed mode, make the window of you client to fill the display as much as possible. This is the best you can do. Besides, when you are Controlling a client in Full-Screen, you can't move files and such with drag-n-drop. So if you want to work on both at the same time, you need to stay in windowed mode.

  • Display blacked out

    All of a sudden, my MacOS display has blacked out (background) and all icons and pix look like negatives. I've checked all Preference settings and can't find anything wrong.  Anyone have thoughts?  THANKS!

  • All Things Being Equal, Is the Apple Display The Best Monitor For A Mac

    Let's put price aside for a second....
    Is the Apple Display the best monitor to hookup to a MacBook Pro (or any Mac for that matter) because the Apple Display is specifically configured for Macs where other monitors are probably more configured for PCs/Windows? In other words are Apple Displays the best out of the box for your Mac (minimal configuration, maximum clarity and crispness, etc.).
    Thanks.

    It's a very good sRGB monitor. The 30 is outstanding. I still think the 23 is a little sketchy; it seems prone to an issue where for as much as an hour you can just discern a ghost of a window that has been up for a few hours; and there are still sporadic reports of weird color casts and "sparkling" effects that can make it difficult to focus on fine details when you're working. The 20 is very good unless you're in a bright environment, in which case you might find its backlight does not go up enough. The 20 has a certain rarity value right now; it's about the last really good wide-format monitor in its size class, though there are still plenty of good 20 or 21 inch 1600x1200 displays out there.
    Bear in mind that because OS X (including, most importantly, Safari) still thinks everything is sRGB, if you get an extended gamut AdobeRGB monitor like the latest 90-series 26 incher from NEC, all the colors in iApps like iPhoto and Safari will come out looking Day-Glo.
    The very best monitors out there -- and here we're talking 24-inch monitors that cost $1,200 and up once you consider tax and/or shipping -- will tend to have things like a polarizing filter on the display itself, HDCP support, dual or even triple computer inputs, and 10 or 12 bit color support that enables profiling within the monitor independently of the graphics card on your computer. Of the above features Apple is particularly overdue on implementing HDCP, which Hollywood in its stupidity has made a requirement for HD movies (why they want to enrich monitor manufacturers rather than themselves I don't know), and the polarizing filter thingy, which further improves the blacks and the viewing angle on IPS panels such as the ones Apple uses in its displays.
    Every now and then a cheaper one comes along -- DoubleSight's latest 25.5 inch ("26 inch" in name only) display comes to mind -- that fulfills all those attractive specifications but usually has some deficiency or other. The most common aggravating feature of cheaper displays, and this has shown up in forums on the DoubleSight display, is you can't turn the brightness control down far enough for domestic use without resorting to hardware calibration and/or pulling back on the individual RGB sliders, which makes color accuracy a problem. But for a brightly lit office environment, and if you're OK dealing with the (hopefully temporary) OS X issues with wide gamut, the DoubleSight is an attractive HD option.
    Now will someone help me decide which of the ACD 20 or 23 causes less eye strain when dealing with text? Thanks in advance.

  • What adapater do I need to connect my mid 2007-2008 imac to a 20 inch apple cinema ?

  • Recommended Apple Displays for vintage 7350, G3/33 and Q650 Macintosh's?

    I am looking for an Apple compatible display solution for a Quadra 650, a Workgroup Server 7350 and a G3/300. At this time I have the following displays at disposal: a vintage 12-inch RGB display which is connected to my vintage Mac LC, a 15-inch IBM G50 CRT with resolution comprised between 640x480@85Hz and 1024x768@72 Hz, and two professional colour CRT manufactured by Philips in the 202P40 and 70 series (which are presently connected to my PC workstations and used as dual-displays on Matrox Parhelia.)
    My original plan was to use the Quadra 650 for creative writing as a replacement for the venerable LC. To this purpose a 12-inch RGB is a bit restricted (512x384), but quite practical from the desk space saving viewpoint. Perhaps a 14-inch Apple display could do well, but which one? Multiple Scan series?
    The 7350/233 and G3/300 are respectively using their original video board and an ATI Rage Pro chipset. Their use would be either dedicated to scanning tasks (mainly digitisation of written media) as well as Internet gateway (for the G3 only). Colour fidelity is not prerequisite at this stage. The 15-inch IBM G50 is a capable monitor, but I think that it would be great to have a monitor with flicker-free resolution of 1024x768 for web browsing. So what is the good choice among vintage Apple displays?
    I read quite numerous articles about Apple displays, and it seems that some models like the 1710 are to be avoided, according to LowEndMac. Conversely they provide excellent compatibility with vintage Macintosh graphic boards. I am particularly concerned with graphic display quality because I spend many hours in front of a computer display every day. This is the reason why I invested time and money to assemble a dual Philips 202P CRT display working space in combination with top-quality Matrox Parhelia graphic boards.
    I also read about issues when using conventional CRT displays on Apple graphic boards because the OS seems to restrict the resolution and refresh rates to 75Hz. But is it true?!
    Again many thanks in advance for your excellent forum and qualitative feedback.

    For your Quadra 650, which you want to use for word processing text, there is an interesting paradox. There is a "hole" in the display capabilities of most computers.
    15 inch displays:
    can easily show 800 by 600, and 832 by 624 will fit on most displays with the picture slightly less than life size.
    17 inch displays:
    can show 832 by 624 with a 3/8 inch black border all around.
    19 inch displays:
    can display 1024 by 768 easily
    If desk space is an issue, the clear winner is a 15 inch display. The difference between Super VGA at 800 by 600 and Mac 16 inch at 832 by 624 is not very large. Either could be used.
    There is a document that discusses the use of sense pins, displays, and adapters with the Quadra series, which includes the Quadra 650:

  • My imac's screen blacks out during booting

    MY imac froze and restarted recently, then when i got into the computer it froze and shutoff again.  This time when i tried to turn it does one of a few things... 1 it only gets to the Apple logo then blacks out, 2 it goes to the place i requested by key commands, or 3 it has the Apple logo, then a loading bar that only loads for about a second and only reaches a very very small fraction of full capacity, then lastly goes to a spinning loading wheel that lasts 5 seconds at most then it blacks out once again. 

    We do not know which iMac or what OS X your on, but that sounds like a hardware problem.

  • 30 Inch Apple Monitor to share with a MacBook & Mac Pro

    I have a MacBook and a Mac Pro, I have (1) 30 Inch Apple Display.
    What hardware can I get to share the same monitor, say with a touch of a button or something, to share the display with both machines are running.
    I want to go back and forth with each machine using the (1) 30 Inch Apple Display.
    Anyone recommend what hardware I need?
    A lot of store clerks have no idea.

    If it's a newer MacBook with Mini DisplayPort, you will need a Mini DisplayPort to Dual-Link DVI adapter
    <http://store.apple.com/us/product/MB571Z/A>
    If it's an old MacBook with Mini DVI, you will need a Mini DVI to DVI adapter
    <http://store.apple.com/us/product/M9321G/B>
    but the 30" will run at half resolution since mini DVI is only single-link.
