Mini DisplayPort to DVI Adapter and macbook pro

I have a 2010 macbook pro 13", samsung 20" LED display connected via mini display port. The setup has been fine for a few months but occasionally both displays would turn blue as it tries to detect itself(I assume) when this happened I would just need to reset to fix itself. This week I used my laptop away from the screen for a while, once I connected it to the display the blue screen has become more prominent, it would blank out for no reason intermittently and has become progressively worse. I've tried shutting down, cleaning the mini-display-port, resetting PRAM and now I'm out of ideas.
Could it be related to the new EFI firmware update v2.5? that was the last major update installed.

You might be better off taking the computer and the display into a Apple Genius Bar annd showing them what is happening.
They may have a fix or maybe something needs to be replaced.

  • Mini Displayport to vga adapter on MacBook pro 13" late 2011. No signal on external monitor

    Hi
    Connecting a Late 2011 MacBook Pro 13" to an external monitor, trough mini Dispalyport to vga adapter, i see "no signal" messagge on external monitor, even if i get it as secondary monitor on Preferences > Monitor of my MacBook it's visible (i can change resolution, position, clone screen, ecc.).
    Any suggestion? somebody found the same problem?

    Hi
    i did what you said and tried with other resolution/refresh rate combinations, also with anoter external monitor (and vga cable) but its still the same: monitor is detected but there's no signal.
    Now I will try to chek if the adapter works on other pc and monitor.
    Thanks
    (anyway it was the firs time i connect this mac to an external monitor)

  • Mini-Displayport to DVI adapter not working, but Mini-Displayport to VGA and Thunderbolt work fine

    Mini-Displayport to DVI adapter not working, but Mini-Displayport to VGA and Thunderbolt work fine.
    This is a brand new MacBook Pro (15-inch, mid-2012) just received.  I suspect that this is a hardware problem as:
    The mini-displayport to DVI adapter and the external monitor that I am utilizing connect and operate just fine using my older MacBook Pro (mid-2010) with the same OS.
    The new MacBook Pro powers the external monitor with a mini-displayport to VGA adapater without issue.
    The new MacBook Pro powers an Apple Thunderbolt display without issue.
    Both MacBook Pro's are running OSX Lion 10.7.4.
    The only combination which does not work is the mini-displayport to DVI adapater used in conjunction with the brand new MacBook Pro (mid-2012).
    All adapters and components (mini-displayport adapters) are Apple retail adapter.
    I have tried several external monitors, including my Dell U2412m.
    When I connect the mini-displayport to DVI adapater to the new MacBook Pro (mid-2012), nothing happens. The external monitor reports "no signal" and attempts to go into sleep mode.  Using the "Detect displays" button has no effect, even when used multiple times.  Rebooting does not help, nor does resetting the SMC or PRAM.
    Any other suggestions before I take it to the Genius Bar?

    I turns out that the logic board of my MacBook Pro was faulty (despite being brand new).
    I took it to the Apple Store, presented the problem, and one of the Tech's came to the same conclusion that I had -- hardware failure.  Phone support was no help in the matter (and even told me that what I was trying to do wasn't a supported option, which is rediculous).  However, the Genius Bar did take care of the problem, and my MacBook Pro was back to me with a replaced logic board within a few days.
    Hope that htis helps.

  • Does DVI-to-HDMI work with my Mini DisplayPort to DVI adapter?

    Hi,
    I have a Mini DisplayPort to DVI adapter and was wondering if I get a DVI-to-HDMI, will I be able to get HDMI output?
    If yes, should I get any specific DVI-to-HDMI adapter?
    If yes, will it have sound with it?
    Thanks.

    So which does the community prefer between Dr Bott DVIator and the Apple DVI to ADC?  I have the Apple but it is not working, as it is shutting the monitor down without even starting it (soft shut-down).   Is this a bad adapter or the result of "stacking" adapters?  I have read that it is more common to a bad adapter result.
    Thanks.

  • Hi I have a recent macbook pro 12" (bought in april 2012) model number A1278.  I'm trying to connect to a 23" apple cinema display (A1082) this currently is not working - i've bought an additional Apple MB570ZA Mini DisplayPort to DVI Adapter - no luck!

    im not sure what to do next - can anyone help?

    Hi There,
    I have had the exact same issue but with a projector.
    The issue lies with Mountian Lion 10.8.2.
    I tried many a combination with no luck to get HDMI working.
    Took my mac into the apple store and came to the conclusion it was the software, so I asked them to install 10.8 onto it (this is destructive so a backup is a must)
    Bought my macbook home and voila, now displaying through my projector.
    There is a small graphics update after 10.8.1 which seems to be the cause.
    Hope this helps.
    Thanks.

  • Mini Displayport to DVI Adapter Problem on Mid-2009 Macbook Pro

    I have a new mid-2009 Macbook Pro hooked up to a 20" Samsung 2033sw LCD with a native 1600x900 resolution using a mini Displayport to DVI adapter that I bought off of EBay. No matter what I've tried I can't get anything to display on the external Samsung LCD higher than 1024x768. I tried switching between GPU's and that made no difference. Any ideas.?

    Michael, thanks for the reply;
    When you open System Preferences/Displays does a second preference panel open up OK on the Samsung ?
    Yes, but I can't see it unless I select 'gather displays'. Then it appears on the MBP LCD, and showing the correct resolution - 1600x900.
    Is there an Options Tab visible under which you can check 'Overscan' ?
    None that I can find. Only display and color tabs.
    Is the Refresh Rate set to 60.0 Hertz
    Yes, that is what it shows in Refresh Rate.
    I also pulled out an older LG LCD that is fairly generic, .e.g. it has DVI in at 1280x1024. Same problem on that LCD ... nothing higher than 1024x768, but this time at 1280x1024 I get major noise and screen distortion. The displayed image is jumping all over the place, but at least there is something displayed.

  • Does Thunderbolt work with the Mini Displayport to DVI adapter?

    I just ordered a new 13" MacBook Pro with Retina Display to replace my Mid-2010 15" MacBook Pro.  I've been using the Mini Displayport to DVI adapter to extend my screen to an older 20" Cinema Display.  From what I can find online, and I'm here asking for confirmation, I should still be able to use the Mini Displayport to DVI adapter with the new MacBook Pro's Thunderbolt port.  Correct? 

    still be able to use the Mini Displayport to DVI adapter with the new MacBook Pro's Thunderbolt port.  Correct?
    Yes.

  • Trouble with 30" HD Cinema Display using Mini DisplayPort to DVI Adapter

    I bought a new MacBook Pro and I am having trouble getting the full resolution to work with my 30" HD Cinema Display (purchased in 2007 max resolution 2560 x 1600) using a Mini DisplayPort to DVI Adapter.
    According to the specs page, http://support.apple.com/kb/SP581 , the max resolution of the HD external display is supported. Unfortunately the max that I can set it to is: 1280 x 800
    Has anyone else had the same issue?
    If this isn't resolved I'm likely going to exchange my MacBook Pro for one that can support this display.

    So I went and bought the Mini DisplayPort To Dual-Link DVI Adapter as suggested and it seems to work great.
    Now the problem that I have is when I open up Apple's DVD player, the screen is blank but I can still hear audio.
    If I unplug the display, the movie will display properly. Rebooting with the display plugged in doesn't help either. I also deleted all the DVD players enc setting files so that they would re-initialize but no luck.
    Any idea what this problem might be??

  • Does Mini Displayport to DVI adapter support analog VGA signal?

    I'm just about to buy a macbook pro. Since the MDP (mini displayport) to DVI and MDP to VGA adapters are £20 a pop, I can only afford to get one. Obviously DVI is better in general, but VGA supports more older hardware, CRTs, and the spare VGA input on one of my displays (where the desktop uses the DVI).
    What I'd like to know is does the MDP to DVI adapter also support the analog VGA signal on certain pins (like most physical desktop DVI ports do)? If it does, since I have about 3 or 4 DVI to VGA adapters lying around, I can get the MDP to DVI adapter and use the DVI to VGA adapters with it if necessary, but if it doesn't I might be better off getting the MDP to VGA...

    No. Unlike DVI, which in the DVI-I configuration has both digital and analog pinouts, DisplayPort (and mini-DisplayPort) are purely digital. Mini-DP to DVI then DVI to VGA will not work. If you look carefully at the Apple Mini-DisplayPort to DVI adapter, you'll notice it's a DVI-D connector - digital pins only.
    The Apple mini-DisplayPort to VGA adapter contains a digital-to-analog converter.
    So, you'll have to choose. If you want VGA, get Apple's mini-DisplayPort to VGA adapter.

  • New Mac Book Shuts Down when I plug in the Mini DisplayPort to DVI Adapter

    I have a new 15" MacBook pro and every time I plug in the Mini DisplayPort to DVI Adapter, it shuts down. I installed the Mini DisplayPort to VGA Firmware Update (http://support.apple.com/kb/dl799) and it still shuts down. It shuts down whether I have a display/projector plugged in or not.
    Any suggestions???

    Try turning the MBP off before you connect or disconnect an external monitor. I could be wrong but I do not believe that the DVI interface was designed to be a hot swap interface.

  • Mini DisplayPort to DVI Adapter does not recognize SGI-Saver on DVI (LCD)

    I bought a Mini DisplayPort to DVI Adapter for my new unibody 17" MacBookPro.
    No dice! The lcd is not recognized, is not seen in the displays control panel, and LCD remains dark. This LCD works fine on the previous generation MacBook Pro when plugging into the DVI connector on that computer.
    The Apple adapter seems not to recognize the DVI lcd panel. What's the fix? A firmware update perhaps?!?

    The adapter works perfectly with a lower resolution Dell LCD panel. I'm hoping that Apple would have a firmware update to enable operation with the older generation LCD.

  • Longer Mini DisplayPort to DVI Adapter too short

    I just ordered a MacBook Pro 15" retina but the  Mini DisplayPort to DVI Adapter that Apple sells seems to be only like maximum 5" only.
    Is there any other reputable brand that sells a longer one (at least 10")?

    Not sure if ill get in trouble for this, and im not associated with this seller in any way apart from buying from them.
    We bought 3 of these for our office and they work very well.
    ps. they are 6ft long

    Hi all,
    Anybody know the difference between the Mini Displayport to DVI adapter MB570Z/A (older and cheaper) and the MB570Z/B Apple currently sells? The "A" version is available elsewhere for about $7 vs $29 for the "B" adapter available from Apple.

  • Mini DisplayPort to DVI Adapter failure misdiagnosed

    When I purchased my new MacBook Pro last December, I had to purchase Apple's Mini DisplayPort to DVI Adapter in order to continue using my Apple 20" Display monitor with it.
    Turns out the Mini DisplayPort to DVI Adapter dies so I no longer had access to use of my Apple 20" Display monitor
    Only the cause of the display's going blank was not clear
    I took my MacBook Pro and the 20" monitor tothe apple store Genius bar.
    Using my computer and my 20" monitor, the Genius tried making it work with my bower block and with another one in the store. Nothing worked.
    What he didn't test was the Mini DisplayPort to DVI Adapter itself to see if that was the problem.
    So I bought a new monitor and that didn't work either.
    I had to go back to the Apple store Genius bar a second time for them to figure out that it was the Mini DisplayPort to DVI Adapter.
    Big PITA (Pain in the A..)
    Poor diagnosis the first time gave me 10 days of frustration.
    What's with that, Apple?

  • Does Mini DisplayPort to DVI adapter output sound?

    I am using the Mini DisplayPort to DVI adapter, like this one:
    with my Macbook Pro 17-inch, Mid 2010.
    I also happen to have a DVI to HDMI cable that I tried to connect to my Samsung LED TV (2014 yr.)
    The picture that I get on TV from the screen mirroring from the Mac is great but I don't have any sound. So I'm curious if DVI could be killing the sound in this case? Any ideas?

    I don't think the DVI standard carries sound, so while Mini DisplayPort can handle audio, DVI probably won't carry it any further.
    Does your TV have an unused HDMI port? MacBook Pros after a certain version do send audio out of Mini DisplayPort and the audio can be carried through HDMI to a TV or receiver. HDMI would be preferred over DVI for this reason, unless your MacBook Pro is too old. If it is, then with either type of connection you would need a separate audio cable connecting the audio-out on the MacBook Pro to an audio-in on the TV.
