Mini DVI to DVI monitor working

I have a Black MacBook running 10.7.3. I have ta Bookendz and a mini DVI to DVI aadpater and two differnet DVI cables. I have tried all combinations and can not get my LG monitor to display anything, it just goes into power saving mode. My MacBook sees the external monitor in the display prefernces, and even has the right resolution set. When I first had the monitor it wouldn't work through and I was going to send it back, but it just started working.
The monitor works fine when plugged into a Mac Mini, or through the HDMI and VGA ports when plugged into my MacBook. Any help greatly appreciated.

The mini-DVD to DVI adapter doesn't pass through the analog video signals needed for VGA, so won't work with a DVI to VGA adapter. All the control signals are there, so the display is recognized, but there will be no picture.
They could have used a DVI-D connector on the adapter, instead of DVD-I, so the DVI to VGA adapter wouldn't even plug in, but then it couldn't be used with some non-Apple LCDs, that use DVD-I connecters.

  • Monitor won't work via mini-dvi to dvi adapter

    It's a brand spanking new mac mini. I attached a 5 year old lcd monitor (always used before as VGA) using the mini-dvi to dvi adapter. I am using the monitor's dvi connector. The monitor resolution is 1280x1024.
    The monitor does not work when using the mini-dvi to dvi adapter. If I remove the mini-dvi adapter and use a mini displayport to dvi adapter, it works just fine. I can keep both adapters plugged in and plug the cable into one or the other. It always works instantly when attached to the minidisplay port and doesn't work if I switch to the mini-dvi port.
    I've tried the display with mini-dvi adapter on my macbook too. On the laptop, it acts like there are two screens attached, but there is no action on the external display.
    As a further test, I attached the mac mini to the TV via a mini-dvi to hdmi adapter. The mini-dvi port on the mini works fine, as does the port on the laptop. The monitor works fine via minidisplay, but not mini-dvi.
    Naturally, I concluded that the mini-dvi adapter was faulty. A second adapter came today, and nothing has changed. Could I have received two Apple mini-dvi adapters in a row with problems? Is there something about the monitor that doesn't like the mini-dvi port? It seems like it wouldn't like the minidisplay port either, but that one is fine.

    • Went to Best Buy
    • Paid for a DYNEX Mini DisplayPort to HDMI Adapter ($25)
    • Came home and plugged in the adapter then the HDMI to DVI cable to the monitor. (Note: Monitor is a LG Flatron L22WTG) - DID NOT WORK
    • iMac knows monitor is plugged in and I can change the resolution on both monitors and mirror. (Note: Changed to every resolutions with/without mirror image.) - DID NOT WORK
    • Restarted computer - DID NOT WORK
    • Turned off/on LG monitor many times - DID NOT WORK
    • Unplugged/plugged back in many different ways - DID NOT WORK

  • Mini DisplayPort to DVI not working, No Multi-Monitor, Jerky Mouse

    I have an iMac, 27 inch, 2009 model.
    Until today I've had a second monitor attached via the Mini DisplayPort to DVI adapter. The monitor is a Samsung SyncMaster T260. This setup has worked perfectly well so far.
    Until today that is. Now the monitor is not recognised any more and if I try to select "Detect Displays" the mouse pointer hangs every few seconds - stops dead and then restarts again.
    What did I do to make this happen? Nothing (that i'm aware of). Haven't installed anything, not done a software update, just literally rebooted and it's not working anymore.
    _*Things that still work...*_
    The Mini DisplayPort to DVI adapter works on a Mac Mini, so that's OK
    The DVI cable works fine when plugged into a PC or Mac Mini, so that's OK
    The Monitor works fine when plugged into a PC or Mac Mini, via DVI, HDMI or VGA, so that's OK
    So I've established that, in isolation, each part of the system is functioning perfectly well.
    *_Things I have tried - without success..._*
    1) Rebooting - both iMac and monitor
    2) Unplugging all cables and reconnecting then rebooting again
    3) Clearing the PRAM - done it twice just to make sure
    4) Updated to OS X 10.6.7
    5) Reset the SMC
    6) Deleted the com.apple.windowserver.plist files at /Library and ~/Library
    7) Googled for solutions - plenty of people seem to have one or the other of these symptoms...
    Can anyone shed any light on what's happened here ? Please help!
    Cheers

    ** Sorry if this is in the wrong place, I just found a forum specifically for the iMac so posted it there but not sure how to delete this one. **

    Well, it would be interesting if that's when it had occurred. At the time, I hadn't installed 10.6.7, and hadn't installed anything immediately prior to the problem occurring.
    It doesn't seem like there's any way (a-la System Files Checker on Windows) of checking the integrity of system files which may have been corrupted, nor a way of reinstalling any update in the case of this happening - or is there a way of doing this? You don't seem to have any control over updates apart from applying them - if something does go wrong, there's no way of backing out. I guess Time Machine is the answer to my own question there.
    I'm happy that it's working now, but it was a pretty extreme fix to have to wipe the entire system. At least it wasn't a hardware issue, I'll be thankful for that!

  • Will this monitor work with Mini-DVI?

    Hi
    I currently have an iMac 20" 2.4GHz 2GBs RAM and ATI Radeon HD 2400 graphics card. I was wondering if using either MINI-DVI to VGA or to DVI will work connecting to this monitor? Considering its such a high resolution.

    Any help much appreciated, thanks.

    answer is YES,
    the dell monitor has DVI so best get the mini-dvi to dvi adapter to get a better picture,
    also you might need audio jacks depending on how your set up will be....

  • Mini dvi to dvi adapter not working with monitor

    arright *** i got a mini dvi to dvi adapter which is connected to my vga monitor through a vga to dvi adapter. The computer recognizes the monitor in display preferences, but the monitor doesn't display anything it just sits in standby mode... any ideas why this isn't working? You'd think if the problem was going from vga-vga to dvi adapter-dvi to mini dvi adapter that it wouldn't even recognize the monitor but it does.
    well that *****, back to best buy to get the other one. Reason i got the dvi one is because i plan on getting a different monitor with dvi soon. But noo dvi adapter wont work with vga adapters.

  • My Viewsonic monitor won't work with the Imac using the Mini Port to DVI adapter.

    My Viewsonic monitor won't work with the Imac using the Mini Port to DVI adapter. I also tried the HDMI to DVI adapter ane the Mac-Mini with same result. The monitor does work on my older Macbook Pro that has the DVI connector. Is it a Software/Driver issue ?

    Should be extremely simple, please carefully read Connect multiple displays to your Mac. If you still have problems then it's probably a cable issue that would be resolved by replacing the adapter cable. You should be using this adapter. If you are using a third party adapter that might be your problem!

  • 27: iMac Apple Mini DisplayPort to DVI adapter quits working post-firmware

    I iMac Apple Mini DisplayPort to DVI adapter suddenly quit working after I installed Apple's latest iMac display firmware update. This is an Intel Core i5; the monitor is an LG Flatron 24" Wide, and when it powers up it says "no video input" and goes into power-saving mode. No amount of replugging cables helps, but the monitor works fine on other computers.
    The Displays control panel just shows one monitor, and clicking Detect Displays does nothing.
    I suspect Apple's Display Firmware Update. My installer log shows the following, but the problem only happened today after the latest update:
    6/1/10 9:45 AM 27-inch iMac EFI Firmware Update 1.0
    6/1/10 9:45 AM 27-inch iMac Display Update 1.0
    6/4/10 11:47 AM 27-inch iMac SMC Firmware Update 1.0
    6/4/10 11:47 AM 27-inch iMac Display Update 1.0
    6/5/10 7:29 AM 27-inch iMac Display Update 1.0
    I have automatic updates disabled, but after each update I would see more firmware updates ready, but caution leads me to never install more than one of these at a time, and then to wait a while to see if anything bad happens. The odd thing is that the Display Update 1.0 seems to have been installed three times in this course of events. Alas, there appears to be no way to uninstall a firmware update.
    Here is the System Profiler Graphics/Displays output:
    Chipset Model: ATI Radeon HD 4850
    Type: GPU
    Bus: PCIe
    PCIe Lane Width: x16
    VRAM (Total): 512 MB
    Vendor: ATI (0x1002)
    Device ID: 0x944a
    Revision ID: 0x0000
    ROM Revision: 113-B9110C-425
    EFI Driver Version: 01.00.383
    Displays:
    iMac:

    Pixel Depth: 32-Bit Color (ARGB8888)
    Main Display: Yes
    Mirror: Off
    Online: Yes
    Built-In: Yes
    Connection Type: DisplayPort
    Display Connector:
    Status: No Display Connected
    It says the Mac sees no display connected, and the display gets no video signal. Since the adapter is an active device (it has powered electronics to convert DisplayPort signals to DVI signals) I suppose it could have just coincidentally died. But that seems unlikely given that the thing worked perfectly just before the last firmware update.
    Does anybody have similar experience, or better yet, a fix?

    Unfortunately the Apple Knowledge Base does not give much information about this update. Such has how to tell if it has been successfully installed. I suspect that because it keeps recurring in the install log that it has not been installed successfully as yet. Are you receiving this update through Software Update? Can you locate the installer for this update? It maybe located in Apps/Utilities.
    Some firmware update installations can be interrupted/corrupted by attached devices. If you find the update's installer on your iMac, I suggest that you detach all external devices from the iMac, use an Apple USB keyboard & mouse if available, follow the instructions carefully and install the update manually. If you do not locate the installer I suggest downloading manually from the link below and installing it.
    The Knowledge Base article mentions that your iMac should also have a Graphics Firmware Update. I suggest that you download and install that as well.

  • External display via Mini DisplayPort to DVI no longer works with MacBook.

    I had not used my external monitor in the last several weeks. I believe there have been a few OSX Lion updates since the last time I used the external monitor. I had installed all the updates prior to connecting my external monitor again. However, a few days ago I tried to connect the external monitor and all I get is a "No Signal" message on my external monitor. The Mini DisplayPort to HDMI works on my LCD TV, so I know  the MDP works. I have also replaced the MDP-to-DVI cord and the external display still doesn't work.
    I connected the external monitor to another computer running Snow Leopard and the external monitor works. So, the external monitor does work.
    I have seen a few posts aboout this, but nobody seems to have a solution that works or is directly on point to my issue. I have tried to use all the scenarios for plugging in the external monitor and external monitor power. I tried to reboot the laptop with and withoout the external monitor connected. Same thing with the exteernal monitor plugged in and no power, etc. Nothing works. I have tried to repeatedly turn the external monitor on and off while connected to the MacBook. Again, that doesn't work.
    So, I am open to any help someone may have. Here is what I am running:
    MacBook, Aluminum 13" Late 2008
    OSX 10.7.3
    NVIDIA GeForce 9400M

    While we all have MacBooks in this forum most of us don’t run Lion. There's a Lion Support Community where everybody has Lion. You should also post this question there to increase your chances of getting an answer. Lion seems to have problems with external monitors.  https://discussions.apple.com/community/mac_os/mac_os_x_v10.7_lion

  • 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.

  • Macbook 13" Core 2 Duo, Mini DVI to DVI will not work (Mini DVI to VGA OK)

    I've recently purchased a used Macbook 13" with a Mini DVI out display port. When I try to use a Mini DVI to DVI adapter to an Acer X223W (or a few other Acer / Dell models), the Macbook screen either blinks blue to white constantly or doesn't do anything at all. When I use a Mini DVI to VGA adapter, it works fine, however, the MAC does not give an option for my monitors native resolution (1680 x 1050).
    At first I thought there was a physical issue with the Mini DVI port, however the VGA adapter works fine. I've also tried a new DVI adapter in case the first one was defective - same results.
    Am I missing something here? I don't think there are options to upgrade drivers on a MAC (I'm semi-new to the platform).
    Thanks in advance!

    What happens if you try just the monitor, e.g. keep the lid down on the MB? The MB should be attached to it's AC adapter to try this. Also, some kind of USB device will be needed to wake up the closed MB. Pretty much anything hot-plugged into a USB port on the MB will cause it to wake up. Would be curious to know if a DVI monitor works under those conditions.

  • 2011 Mac Mini and Acer x222w monitor incompatible? HDMI to DVI adapter issue

    I am totally bummed because I just bought a new Mac Mini thinking I'd be able to use the display from my old system, an Acer x222w, which has both DVI-D and VGA connections. I hooked the monitor up using the HDMI to DVI adapter included in the box with the Mini. On boot, I could see the Apple logo, though it was not centered, and when the set up screen came up to the select language screen, it flashed quickly and then turned to snow.
    I was on the phone with Apple support for over an hour trying to troubleshoot this issue. I was a little disappointed that tech support didn't even seem to  be aware that the Mini came with an HDMI to DVI adapter. It was then recommended that I try an adapter for the mini display port, which the 2011 Mini doesn't have.
    I was able to borrow another monitor, a Dell with DVI-D, and it worked.
    I have searched for specs/requirements that might explain why the Acer monitor doesn't work while the Dell one does. I cannot find anything from Apple. I just assumed any DVI connection would work. Has anybody else encountered this problem? Most of the issues I've found on the forums involve trying to hook up to a home theater LCD TV, which I'm not trying to do. If I had known my monitor wouldn't work, I probably would have just saved up for an iMac.
    Thanks in advance for any thoughts or tips!

  • 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.

  • Mini DVI to external monitor (VGA) problem/firmware update does nothing

    Hi,
    Four months ago I bought a new white 13-inch Macbook (2006 model I believe) along with a handy mini-DVI - VGA adapter. I used a Hanns-G HU196D external monitor which worked fine for a couple of months but then stopped, and had the same problem with a (much cheaper) 'LiteView' monitor. I find it bizarre how they work absolutely fine and then stop, with no damage to the adapter, cable or ports. I've since bought a new adapter and cables + trying out a different monitor and still the same problem...
    I've installed a firmware update that describes the exact symptoms, but it's done nothing. Can anyone help me resolve my issue?? It's still under warranty so is it an unusual problem that'll need to be fixed by Apple?
    Thanks

    Are you using the mini DVI to DVI followed by a DVI to VGA adapter? That may not work if the mini DVI to DVI adapter does not pass analog video. If that is the case, you need the mini DVI to VGA adapter:

  • DVI to ADC Adapter + Mini DVI to DVI Adapter = usb ports don't work?

    I have a 23" Cinema with the ADC plug. I've been using it with the DVI to ADC adapter for many years, though I did not use any of the monitor's usb ports during this time. I recently bought a new Macbook, so now I have am combining a Mini DVI to DVI adapter with the DVI to ADC adapter. The display works fine, but now I find the usb ports on the monitor do not work. I've checked all the pins involved and they are all straight and look normal.
    Does this have anything to do with the double adapter situation, or could it just be that the monitor's usb ports are aging and haven't been used in a long time? Or is it possible these ports do not support usb 2.0 devices?

    Thank you Malcolm.
    It's true I cannot adjust the display's brightness using the buttons on the monitor. But I can put the Macbook to sleep, both when the adapter's usb cable is plugged in and when it's not.
    So if the usb circuitry has gone bad, will this cause me any other problems, or can I just ignore it? Right now I am trying to choose an external hard drive to buy, so I'm taking stock of my available ports. I don't think I'd put a big hard drive on a usb 1.1 port anyways.

  • Mini Displayport to DVI working in Bootcamp but not in Leopard

    I've got a new unibody MBP together with a mini displayport to dvi adapter.
    When I connected the dvi cable with the MDP2DVI adapter to my new MBP and my 3-months-old Benq 20" LCD monitor, nothing shown up no matter how I tried. The monitor just kept saying no signal could be detected.
    Being frustrated so I did some googling, and I'm surprised by the vast number of people who have got problems with the external display!! I really didn't notice this before I decided to buy this MBP and I'm a little regretted, coz the 2nd monitor is so essential to the productivity of my work...
    After searching around for a solution for some time, I am pessimistic of waiting for a solution from apple as I see some people had already address this issue in late 2008 but till now seems no solution had came out.
    Last night when I use bootcamp to enter Windows XP, surprisingly it can recognize my external display!!! So now I am quite sure that it's the problem of Leopard but not the display hardware nor the adapter nor my monitor/cable. Did anybody have the similar problem as me tried this in bootcamp??

    keepyourpower,
    For what its worth I've been having much the same issue with my Macbook Pro. Leopard will refuse to see the external display while Windows Vista on bootcamp 90% of the time will but not without some effort. I've been able to get Leopard to use the display after going in to Windows and manually selecting display attached in the display properties menu. It doesn't always work but it will sometimes.
    I'm 100% sure there is a flaw in the logicboard on some of the 2.4 Ghz that is causing this issue. I recently sent my portable in for repairs and they replaced the display which is why it was in and the Logicboard. I'm not sure why they replaced my Logicboard nothing was wrong with it, but with the new one its having much the same problem as you. As I said before I'm 100% sure this is a hardware defect in the Logic Board and if you are within your 14 day return window I'd see about asking your local Apple store to exchange the unit for a new one.
    Not really sure if this will help you at all but didn't want you to think you were alone with this issue..
