Mini DisplayPort to DVI issues

I just recently purchased the new aluminum MacBook, having previously owned one of the very last iterations of the white MacBooks.
With my old white MacBook I had purchased a Mini-DVI to DVI adapter, and was using that to connect to a DVI to HDMI cable, and that cable was going into my HDTV. I would select and check Overscan under the Display Options of my HDTV, which appeared as PDP-xx50SX under my MacBook, and two black bands would be added to the top and bottom of my MacBook's display, and I would get a full screen crisp image on my HDTV that I was very satisfied with, I would use this to view TV Shows and Movies on Hulu without any issues.
I no longer have that MacBook as a few days ago I got my new aluminum MacBook, and with it my Mini DisplayPort to DVI adapter. 4 hours ago I wanted to catch up on The Office, so I plugged in my new adapter to the Mini DisplayPort, hooked up my DVI to HDMI cable, and that into my TV, just like I did with my previous MacBook. That was 4 hours ago, and I am still unable to properly configure it like my last MacBook.
I have been beating my head for 4 hours now looking across every forum on the internet, every thread, and every possible way to type out this issue on Google to find any and all results. For some reason I just do not get the Options tab like I was able to on my old MacBook where I could then select the Overscan checkbox.
This is really frustrating, I've tried every possible combination of resolution, mirrored and not, and nothing works like it did with my old MacBook. I simply cannot get a correct full screen image on my HDTV.
Is this a firmware issue? Has it already been addressed and I somehow missed it? Is there any fix? Is this the cause of DisplayPort? Why wouldn't nVidia's 9400m be able to do the same thing Intel's GMA X3100 did? So many questions, and I didn't know where to turn to so I came here to the Apple Support forums hoping I'd get some resolution or reassurance this is something that will be/is being addressed. The only fixes I've seen online are programs like SwitchResX or DisplayConfigX, but I'm not that technically savvy and would rather not fry my screen, especially when it worked perfectly out of the box with my older MacBook. Help!

I am also frustrated by the new display port. I have purchased a DisPort to DVI connector from the Apple store and the pin configuration is different than previous all other Apple adapters (DVI-I). The 4-ins around the blade are missing in the new adapter. The genius bar said in Orlando that the new adapters are a new version of DVI called DVI-D. So all my previous investment cabling is hosed. I was away from the home 20 so I purchased yet another $29 VGA adapter from the Apple store to complete my mission.
Moral of the sad story - Buy a DVI-I to DVI-D adapter if you own and use a MacBook for presentations. The Apple Store does not carry them.
Hey wait a minute is this tied to the disappearing Firewire connector???
Mike
PS - I was ablt to find a DVI-D to HDMI connector that I will try when I get back home...stay tuned!!

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??

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.

im running OSX 10.7.4

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 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
Mart
** 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!

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..

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 - 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 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,

Mini DisplayPort to DVI Adapter does detect all resolutions in Ext. Disp

Think another EFI Update is in Order, Just used the Mini DisplayPort to DVI Adaptor to a NEC 3090WQxi Monitor and the Max Resolution is only 1600X1200, while my older (Late 2007) Macbook Pro needed an EFI update for Graphics before it detected the available resoltions for the same Monitor. Apple Support please fix this issue, or direct me in solving a very frustrating Problem
I do not have the Boot ROM Version or SMC Version sonce I had to revet back to the other Macbook Pro.
Cheers,
Mike

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.

No Video from Mini-DisplayPort or DVI, only Dual-Link DVI

Just got my new Mac Pro 6-Core delivered. Out of the box, there were problems. I have a Dell 27" monitor that takes Dual-Link DVI, DisplayPort, or HDMI and a Dell 22" monitor that takes DVI, VGA, or HDMI. I am using a DisplayPort to Mini-DisplayPort cable to connect my 27" monitor to the Mac Pro and a DVI cable for my 22" monitor. I have the ATI 5870 graphics card installed OEM.
The problem is that the graphics card appears to not be switching to Mini-DisplayPort or DVI for output. It only works when I plug in a Dual-Link DVI cable to my 27" monitor. At that point, I get a video feed on my screen on a hard boot. At this point, I can then plug in my Mini-DisplayPort cable to my Mac Pro and unplug the Dual-Link DVI cable, and it switches video feeds perfectly. The problem then is that when I restart the computer, or power off and power on, the problem starts all over again. I HAVE to boot using the Dual-Link DVI cable for anything to work.
Ideas? Called AppleCare, waiting on engineering to see what they have to say. All the cables work perfectly when I plug them into my MacBook Pro (Late 2008). I am stumped.

I seem to be having similar problems. I bought the same system (6-core Westmere with the 5870 graphic card installed OEM) last month and I seem to be having problems running two Dell monitors which I know to be perfectly fine.
For the past month, I've been using a 24" Dell U2410 monitor with my Mac Pro using a DVI cable. Absolutely no problems at all. I then purchased another 24" Dell U2410 with the intention of running with dual displays. To prepare for this, I bought two mini-DisplayPort to DisplayPort cables from Monoprice. When I finally received the second display, I turned off the computer, hooked up both monitors through DisplayPort using the two mini-DisplayPort connections on the graphics card and turned on the system. I got two black screens. I tried to use keyboard commands to bring up the shutdown dialog box but it wasn't working. So I was forced to do a hard shutdown by holding down the power button for 10 seconds.
I went through a series of combinations of power cycles for the displays and computer and still two black screens. Finally, I went back to square one, a single display through a DVI cable. Again, a black screen. At this point, I disconnected the display from the computer. Power cycled the display (this initiates the self-test for the Dell display), hooked it up to the Mac Pro, turned it on, and it worked. I had one working display. Then I plugged in the second display using the mini-DisplayPort to Display port cable and that worked also. Finally, two working displays. For some reason, the Mac Pro recognized the display using the DisplayPort as the primary monitor. I rebooted the Mac Pro and the monitors continued to work properly. I booted into Windows 7 and again, no problems. I went back to OS X and used the computer for the night. When I was done, it put it to sleep.
This morning, when I tried to wake it up, same problems. I had to go through a series of power cycles and cable swapping to finally get a single screen to work.
I went through some of the troubleshooting documents here in the Support area and found this one:
http://support.apple.com/kb/HT4279
I am going to pick up the Apple mini-DisplayPort to DVI adapter and try running the display as two DVI monitors. Hopefully this will fix those problems. If the AppleCare engineer is able to give you anymore information, please let us know. This is a worrisome issue.

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:

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 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.

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.

Have I power down Macbook and monitor (or TV) before connect (or disconnect) through Mini DisplayPort to DVI (or Mini DP to HDMI) Adapter?

Can I hot plug monitor (or TV) through Mini DisplayPort to DVI (or Mini DP to HDMI) Adapter? Or I have to power down all before connect/disconnect through Adapter?

Thank you, Mario.
I just wanted to be shure because previously i destroyed two videocards on my pc by plugging hdmi without power down.
