Mini Display port DVI adapter not working on Thunderbolt Port

For some time I've been using a mini display port to DVI adapter on an slightly older MBP to connect to my HD TV. I recently purchased a MBP with a Thunderbolt port and when I try to connect it to my TV via my mini-display-port-DVI adapter things are not working properly. The MBP is seeing the Philips TV but it isn't listing all the display modes and I'm not able to send any video to it. Does the Thunderbolt port require a new display port to DVI adapter?

Let me be clearer; I've got the MDP-DVI adapter connected to a cable that is DVI on one end and HDMI on the other. I've got both laptops so I can compare side by side. I plug in the MDP-DVI adapter to the old laptop and all works well; I plug it into the new laptop and while the laptop does see the TV, the display modes for it are all 1080p which is wrong I don't see any desktop image on the TV unlike when I plug it into the older laptop. This is very disappointing as I expect things to just work with Apple products.

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.

Mini display to DVI adaptor not working?

Just bought my first Mac, Its a Mac Mini 2.3 i7. Tried to hook my monitor up with an Apple mini display to dvi and when I powered on my Mini got a white screen with apple logo then monitor went black and started searching for a signal. When I switched it over to the HDMI to DVI it works fine. I plan on running dual monitors as soon as my second one comes in,they only had 1 in stock had to order the 2nd one. started with the mini display to DVI first because of the problems I have read about the hdmi port. Monitor is a Dell E2311H 1920x1080 at 60Hz. Any help would be great! Thanks

The issues you read about regarding the Mini's HDMI port are from people using that port to an HDMI monitor/TV. So, HDMI->HDMI. As you mentioned, you're working fine with the supplied HDMI->DVI adapter. I'm surprised that the MiniPortDisplay->DVI isn't working I have one that plugs into the Thunderbold port and it works fine.

Mini displayport to dvi adapter not working

hello,
I have both a 2008 Mac Pro tower with 2 Apple Cinema Displays, and a newer MacBook Pro that I'd like to hook up to one of the monitors.
The 2 monitors are both DVI, so I bought a mini displayport adapter to plug into the thunderbold port on the MacBook Pro and the other end to the monitor.
When I plug it all in, I get no video on the monitor. I am sure the monitor works, I'm sure the cables work (from the monitor), not sure about the adapter (I just bought it, so it could be bad)....
I did see quite a bit of the same issue online, thought I couldn't find any help in fixing it.... short of driving back to the apple store and replacing the adapter, I'm wondering if there's anything else I should do to trouble shoot this....
I've restarted the computer, checked all connections, nada....
help??

The problem was simple: my laptop wasn't plugged in...
The desk where the Mac Pro is isn't where I typically use my laptop, so I carried the laptop over and plugged the monitor in, when that didn't work I looked online and checked here- I also returend the original adapter to the apple store. I inquired about it there, and the genius asked if my laptop was plugged in when I tried it out... sooo when I got home I tried it again with the new adapter and with the laptop plugged in, and it worked right off the bat with no trouble shooting or "detect display" necessary...
The laptop must be plugged in for the external monitor to show up...
now I know.

Best Mini Display to DVI adapter for 2011 17" MBP w/no blocked ports!

I am looking to get a Mini Display to DVI adapter for my 2011 17" MBP.
+(Preferably it would even be one with a 6' cord.)+
It is not clear which one I should buy. Apple's (adapter only, no cord), is $30, while I can see others for far less on Amazon.
I have read that some of these adapters actually block the FW800 and USB ports on either side.
A blocked, or displaced FW800 port is a deal breaker.
1. Can someone with a 2011 17" MBP tell me that they have either one of these adapters, or the one with the cord, and that it doesn't block their FW800 port? (I'll pay the $30 (albeit grudgingly) if its the only one that works.)
2. This may be a dumb question, but the specs on these adapters say that they are capable of 1080p resolution. Would that mean they would work with a 1920x1200 monitor?

You might want to try the "MBP Display" discussion threads, might be able to find what you are looking for in there or get better support there.
I don't think I can help very much, but I have the Apple's adapter (no cord) and it doesn't block my usage of FW.

HT3382 With a MacbookAir (mid-2012) using a mini DisplayPort to VGA adapter plugged into the Thunderbolt port, can you configure the external monitor to FULLY display in portrait mode yet keep the built-in display in landscape mode?

With an 11"-inch Macbook Air (mid-2012) using a mini DisplayPort-to-VGA adapter plugged into the Thunderbolt port:
Can you configure an extended desktop with an external monitor (20") displaying full portrait mode (1200 x 1600 resolution) and keep the built-in display in landscape?
I'd like to see something like
External monitor / Built-in display

Yes, I can't see why not.
Just give it a try and report back if you have a problem.

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.

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.

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

Pixel Depth: 32-Bit Color (ARGB8888)
Main Display: Yes
Mirror: Off

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.

Mini DisplayPort to DVI Adapter not being recognized...

I wanted to run two monitors off my Mac Pro - a Dell S2409W and an LG Flatron L1920P. Forget for a moment the ugliness of this set up, if you will. My problem is whichever monitor I connect to the mini displayport to DVI adapter isn't recognized. When I go to the Display preferences and click 'Detect Displays', I'll only get whichever display is connect to the DVI out.
All the cabling I have here is DVI-D. And the adapter is brand spanking new. I've tried the different combinations of booting the machine, then turning on the displays, turning on the displays then booting the machine, etc.
Does anybody know what I'm missing here?

Hi,
Do you see the adapter you have listed here?
http://store.apple.com/us/browse/home/shopmac/macaccessories/displays?mco=OTY2ODUwNQ
Supposedly the one that works the best is the $99 one. Imho, that mini-display port has been a problem from the start. Some companies are offering products as work arounds, such as Griffin. The ones I've seen are pretty pricy though.
Oh, there is one thing, pretty remote maybe, but I found that the plug that goes into the card has to be nicely shoved in there. I've put it in thinking it was all the way in and it wasn't.

Mini Displayport to DVI Adapter not sending signal to DVI Monitor

I have a dell monitor connected to my Thunderbolt Display that will not get a signal. The component string looks like this
MBP - Thunderbolt Display- Mini Displayport to DVI adapter- Dell 22" DVI monitor.
I would like to use this monitor as a third monitor instead of collecting dust. Any help would be appreciated.
Thanks,

Hello fuzzymelton,

Mini DVI-Adapter Not Working

Today I went to the Apple Store and got myself one of those fancy new Mini-DVI to DVI adapters, hoping it would work with my screen at home, which I had previously running on the Mini Displayport to VGA Adapter on my original MacBook.
Strangely, when I plugged the cable into the adapter, and into my computer, nothing happened. I did not get video on the screen, nor did my MacBook detect it. I have tried re-plugging the Mini-DVI adapter and clicking Detect Displays in the Displays Preferences multiple times, but no luck.
I have seen the screen work with DVI about a year ago, but that was on one of the original MacBook Pros. Am I better off returning this DVI adapter and instead buying a Mini-DVI to VGA Adapter?
Thanks for any help in resolving this problem.

I have a 22 inch ViewSonic that I got from a friend about a year ago. I did indeed plug the monitor directly into the adapter.
I brought my computer, adapter and cable all into the Apple Store, and they said it was all OK, but did replace my DVI adapter thinking it was probably defective. I got home, tested it on my monitor, but still not working. I tested it on a newer HP monitor that's on the family computer, and oddly it worked there.
A bit of research revealed that the adapter did not send Analog signals on DVI anymore, which confuses me, since the MacBook actually does have Analog signals on that port. I brought my DVI adapter in original packaging in to the Apple store again, and they replaced it with a VGA adapter for free, and sure enough, that solved the problem for me.
Lesson Learned - don't use DVI with older monitors, stay with VGA.

Mini DVI to DVI adapter not working for MacBook BlackRAM upgrade for MacBook black (Early / Mid 2008 model - MB404LL/A)

Hello.
I have recently purchased an external display monitor (LG D2342P LED) and I am trying to connect my MacBook black - MB404LL/A (Mac OS X 10.6.8, Core2Duo 2.4 GHz) to the LG LED monitor using mini DVI to DVI adapter. The dispay is getting detected by the macbook in the display preferences but the screen shows "No video input" ( as a blank-black that bahaves as no input coming to the Monitor).
Please help, what should I do to connect to the monitor ? Is there any setting that I am missing that needs to be preconfigured or is this an issue with software update of 10.6.8 ?
Thanks in advance.

Thanks for the reply, shldr2thewheel. I ll go ahead with the RAM specification you have mentioned.
Can you please suggest about the Hard Drive, what should be the specification I should be looking for compatibility of my MacBook black ?

Mini DisplayPort to VGA adapter not working under Vista (Boot Camp).

Hi there,
I'm facing a very serious issue with MacBook Pro Unibody running MS Vista under Boot Camp: using the Mini DisplayPort to VGA adapter to hook a projector is 95% impossible because the only resolution available is 640x480 or sometimes 800x600. No solution came from the adaptor firmware update, still same behavior: connecting the external projector/monitor toggles 640x480 resolution with no more choices available. Just 5% of attempts on selected projectors gave me access to the complete resolutions list.
This is having a serious impact on my job where I do need both Mac&Windows running natively and with external display capabilities, please I'm looking for some feedback from users facing the same problem or someone who had an official answer on this issue from Apple. Do avoid posting about using modded display drivers please: I know they exist but the adaptor should be working with original ones.
I can understand Apple does not support MS Vista issues but this seems to be a hardware/driver one.
I'd like to point out I'm using a clean Vista installation with Apple drivers (from the Leopard DVD) and I've run Vista (same version, same gfx drivers etc) under Boot Camp on my previous MPB (with integrated DVI output+adapter) on hundreds of different projectors with never a single problem.
Any feedback is really appreciated.
L.

I'm having the same problem. When I try to connect to the switch in our conference room (connecting both a flat panel display and/or a projector, both with much higher native resolutions), all I get is 640x480. This is a huge problem to using bootcamp, and I really need to get this to work. I was able to get a higher resolution 1280x800 on a separate, portable display, so I'm wondering if people have the problem with standalone projectors or only with projectors connected to some sort of switch, in my case an Extron MPX423A. I have also tried this in both Windows Vista (32-bit) and Windows 7 RC1 (32-bit), with the bootcamp drivers and the latest NVidia drivers, and the behavior is the same all around.

Mini DisplayPort to HDMI Adapter Not Working

I just got a mini displayport to hdmi adapter that I ordered from dealextreme and it does not work. The adapter had very good reviews and not one review said it didnt work. When I plug in the adapter (with or without a hdmi cable attatched to it) to my macbook, the screen blinks and then goes back to normal. When everything is properly connected the tv shows no input signal (I am on the correct input channel) and the screen doesnt appear in the displayas settings in my macbook pro. I tried to reboot the macbook, shut down and turn on the screen and nothing seemed to work. The detect display option in the system preferences didnt help. I appreciate any help I can get.
