Problem: Mini DisplayPort to DVI Adapter with Samsung Syncmaster 2033HD

Hi,
I am using the Mini DisplayPort to DVI Adapter to connect to a Samsung Syncmaster 2033HD
However, I get No Signal with DVI as the Source.
It works when plugged into the DVI slot of the Mac Pro.
Any help would be much appreciated.

DisplayPort and its variant Mini DisplayPort, use a new and different protocol for communicating with your display.
A properly-functioning adapter can request the DisplayPort use "Dual-Mode", which produces a good approximation of single-Link DVI/HDMI. This is good for resolutions up to 1920 wide, which would include your Samsung (1600 by 900).
Wider displays require a more expensive "active" "powered" converter, to convert DisplayPort to Dual-Link DVI.
So if the display works with a straight DVI connection, but not a DisplayPort adaptation to "Dual Mode" DVI the weak link appears to be the adapter, but you cannot quite rule out the display card.

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?

Yes.

Resolution problem with Mini DisplayPort to DVI Adapter

Hi,
I have a unibody MBP 15', running on 10.5.8. I use 'Mini DisplayPort to DVI Adapter' (http://store.apple.com/us/product/MB570Z/A?fnode=MTY1NDA5OQ&mco=Nzk2MDk5OQ) to connect to my external HP LP3065 30' monitor. I get max resolution of 1280 x 800 for external monitor which supports resolution of 2560 by 1600.
This monitor used to work fine with old MBPs, but not with my unibody MBP. What could be the problem? Adapter or MBP?
I am missing high resolutions
Thanks in advance!
Rohit

You have the wrong adapter. The one you have is single-link DVI, which does not support 30" displays. You need the Mini DisplayPort to Dual-Link DVI Adapter:

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.

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 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 Displayport to DVI adapter problem

Using a mini displayport to dvi adapter results in a jumpy mouse and a delay on screen when typing text. I've searched for days, but couldn't find the answer. I am using an iMac 27" i7 8GB and as additional monitor a Philips 220WS.
Can anybody help me?

I havent seen the text issue yet but I dont think I tried typing because I use the cpu with two screens for editing and I got frustrated and unplugged the second monitor. Ill try it and get back to you. Thanks for chiming in we need to get a solution to this as its one of the main features for me.
I wonder if we can call apple with this one as it seems to be a defect.

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.

MB570Z/A vs MB570Z/B Mini Displayport to DVI adapter

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.
Thanks!

Mini DisplayPort to DVI Adapter - Monitor not recognizing

I have a new MacBook purchased last month from Apple to replace an older MacBook. I used a Scepter X20 monitor on the previous MacBook with an adapter with no problem. With this new computer, I had to puachase a Mini DisplayPort to DVI Adapter. I plugged it in as I did for the other computer, and the monitor doesn't recognize it at all. I checked the monitor by plugging it into another Mac (older version) with adapter and it works fine. Why will my Mac not recognize the monitor or the monitor recognize that it is connected?

On the very slim chance this might be problem, it happened just last week to another poster and it's happened to me, the mini display port really takes a good shoving into the graphics card. Sometimes it will look perfectly seated in there, but it's not quite.
Aside from throwing that out there, I would think if that wasn't the case, you may be having problems with the adapter itself. The whole mini display port is ridiculous in itself, but the two lessor expensive adapters I bought from Apple worked very poorly anyway. And on Apple displays!
The $99 dollar one Apple sells has a reputation for working the best, but I haven't tried it. There are also devices now, still pretty expensive, that seem to bypass those altogether.
I can't say if some other issue is going on or not, there may be. But just know you're not alone in having display problems of this kind.

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?
Steve

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.

Any Mini DisplayPort to HDMI adapter with audio for macbook pro mid 2009

connecting MacBook Pro (15-inch, Mid 2009) to Hisense TV with audio?!?!!?
hello everyone.
if anyone is familar with successfully getting the older macbook pros that dont support audio out to stream and preform digital audio on a TV or has any helpful information that will get me familiar with trying to successfully stream audio and visual. and can PLEASE HELP ME in any way to understand what they know and teach me how to solve my problem id really appreciate it.
i want to connect my MacBook Pro (15-inch, Mid 2009) to my Hisense LED LCD TV, ModelNumber:40H3E and getting digital audio sound from my TV as well as video, but have no clue on how or where to even start to successfully pairing the two and getting sound.
I own a MacBook Pro (15-inch, Mid 2009) this MacBook model doesnt support an HDMI port. My MacBooks model has the Mini Displayport which supports video out but does not support audio out. Can someone help me by telling me exactly which Mini DisplayPort to HDMI adapter with audio will support my model MacBook Pro (15-inch, Mid 2009) and exactly what HDMI wire do i need to buy that will successfully preform digital audio and sadisfying quality visual through TV?
i have NO expierence with the proccess have NO knowledge about any of this or these Mini DisplayPort to HDMI adapters with audio. i have no idea what kind of adapter and HDMI cord to buy that will give me sound from my tv for my type of macbook. '
im not familar AT ALL with any of this so i hope me giving you my MacBook Pros make and model and my TV's model number will be enough information for someone to help me.
just please give me anything you can on this topic
thank you so much,

With a 2009 MacBook Pro, you need to use two connections to your TV: one for video and another one for audio. The miniDisplayPort on the 2009 models does not support audio, so you need a separate audio cable:
miniDisplayPort adapter for video - I use the Apple miniDisplayport-DVI adapter + a DVI-HDMI cable like this one
audio cable for audio - use a 3.5mm male stereo-to-2xRCA male cable like this one
Connect the miniDisplayport adapter + DVI/HDMI cable to your MacBook Pro's miniDisplayPort output and the HDMI input on your TV
Connect the audio cable to your MacBook Pro's audio out and your TV's audio in
The only potential gotcha is if your Hisense TV requires audio via the HDMI cable when you use an HDMI cable. The H3e user manual is unclear about this.

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)

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.

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.
