MacBook Pro :: Mini DVI Port Not Working?
Jun 25, 2014
I often watch movies streaming on the internet by connecting my Macbook to my television via my Mini DVI to S-video adaptor cable.Last week, however, it suddenly stopped working. The television can still detect the display, but the image is super distorted and moving in a static-ey way. I can only vaguely make out the icons on my desktop on the TV screen.I thought that perhaps my adaptor cable was at fault, so I bought a new one - but the problem remains. I have also tried resetting the PRAM, repairing the disc and permissions with Disc Utility, and cleaning the Mini DVI port. I am pretty certain that it is a hardware problem with the port itself. One of the pins on my Mini DVI port looks like it could be out of place. It is kind of squished at the bottom of the port instead of laying flat like the others.

I’m thinking that this might be the culprit. Is there a way to repair the port without having to replace the whole logic board? The Macbook in question is a 2008 Core 2 Duo running Lion.

I finally upgraded from my 15" PowerBook 1.67 to the new 13" MacBook Pro 2.66. On the PowerBook I would usually run an external display using a single link DVI cable. I have read about the issues with the apple mini display adapters not working on DVI-I or non fully digital displays, but since I had been running the external via single link DVI (digital correct?) I figured that I wouldn't run into any problems. I did some troubleshooting with what I had and plugged my computer into my TV through the mini display adapter to a single link DVI to HDMI cable and all worked fine. Do you think that a dual link DVI cable could solve the problem connecting to my monitor? Or is my monitor flat out incabable? Third party adapter? Worst case I could just go VGA, though I don't want to. My monitor is a Sceptre x20.

Relevant newbie to the mac world. I have a MBP late 2009. I bought a third party Mini display port to HDMI converter so I can hook the MBP to my 46" Samsung screen.
This works fine, no major issues here. However the picture is not great. I compared watching a standard definition TV show through the MBP then burnt it onto a DVD. The DVD (using the PS3 as my DVD drive, connected via HDMI) had superior quality than through the MBP.
Also the picture does not quite fill the screen. There is a small black border running all the way around the screen. Does not sound significant but when doing the same comparison as above, you notice the difference when via DVD the movie fills the screen. I have played around with the resolution settings. Those that fill the screen chop bits of the mac desktop off, so thats no good either.
So I am wondering why this is? Is it because the mini display port is not a DVI port, hence I am not getting true HD quality picture? How can I overcome this if at all. I'm thinking of getting a mac mini as a media hub/HTPC but want to ensure I dont encounter the same problems.

Just a piece of info for those considering driving a 30 inch Monitor with the Mini: The mini-display port to Dual Link DVI adapter Apple is offering is not working. There are some other forums discussing this problem with the unibody Macbook pro. I've been using mine since Dec. At irregular intervals the screen becomes blurry (weird double lines all over), and the only thing that works is plugging back in or (more harmless if you have multiple projects up and don't want them to be scattered all over the screen) Control-Shift-Eject to put the display to sleep, then wake it back up after a few seconds with mouse or keyboard. This can be very annoying as sometimes one has to repeat it multiple times. Apple is aware of the problem, but has not come forward with a solution. I just don't want you guys to be disappointed in your new Mini with a capable graphics card...

as the title suggests, I purchased a Mini Display port to DVI adapter for my Aluminium Macbook but when I plug it in and connect it to my Dell 24inch monitor, it doesn't detect it.
I remember reading about 2 different types of DVI but i was assured that the Macbook supports both types.
Anyone have any ideas?

I've been having an annoying problem lately. The ethernet port on my Mac Mini seems to have stopped working. It happened when I was switching routers. Most likely I just unplugged it from the old router, and into the new one. After that, no more connection, nothing changes when I plug something in.
As far as troubleshooting goes, I've plugged it into other ports, and into my MacBook Air (Just to get a Self assigned IP) and nothing works. I know these ports work with my other computers. I've reset the SMC and PRAM.It works in bootcamp so this makes me think it's not hardware. Any other suggestions?

Problem:
Apple Mini Display Port does NOT work at resolutions over 1600X1200 on NON Apple Cinema Displays.
That means if you own any other brand of monitor such as NEC, Lacie, etc. you will NOT get native resolution on your 24 inch monitor as it is stuck at a maximum resolution of 1600X1200.
This story was mentioned on "Macbreak Weekly" show 4-14-2009. I have since checked with a few people and it would indeed seem to be true at this point.
I REALLY hope a solution from Apple comes soon and this is not some new policy of theirs. If so, it may be the last Mac Pro I will or can ever own. The reason is I do a lot of 3D work with C4D, Vue, Modo and Photoshop CS4 so I MUST have a monitor like the high-end ones from Lacie that have 100% color gamut and Adobe RGB. I can NOT be tied down to an Apple Cinema display due to that work. At this time, it seems this means I would only get 1600X1200 resolution on that 24 inch monitor.
I am HIGHLY concerned by this. Has anyone else confirmed this too and if so what the heck is Apple thinking or better still going to do about it? I LOVE my Mac Pro but if they start forcing Apple displays on us then I won't be buying another Mac, it's just that simple.

I have a 15" unibody MBP bought in Nov '08.
Had been using the Mini Displayport > DVI adapter just fine with both HDTV and Dell monitor, BUT then all output has stopped completely!
No monitor is detected by the laptop (although the display does blink blue, as if it had detected it), tried different cables, different displays, using the Displayport firmware update, speaking to Apple, deleting the com.apple..plist files, etc
Edit: it also doesn't work in XP on Bootcamp

6 weeks ago I bought a Mac Pro Dual Quad 2,66 with an ATI HD 4870 graphic adapter. System is OS X 10.5.7. I try to get an Eizo 30" display (SX 3031W) working with this configuration. Using the signal connector #1 on the Eizo , the display will show up to 2560x1600 resolution (as it should be) but after selecting this option will fall back to 1600x1200 pixel. I tried installing on the DVI plug of the card and also on the minidisplay-port using the "Mini Displayport to Dual Link DVI adapter" from Apple but up to now it does not work.

How many of you would like to see a HDMI Port? Why the miniDisplay port? Why not remove ethernet jack and miniDisplay port and replace it with a HDMI port. That way one HDMI cable feeds digital video AND audio. Am I the only one thinking of this?

I am having issues with my Dual Band 1TB time capsule for some reason the damn ports won't forward I have enabled the correct settings with the ip address and the ports, but when I use a program to test if the ports are open they are always closed, regardless on pc or mac. Does anyone have a solution to this? I even reset my Time capsule to see if it would work, but no luck.

I need to connect my 09' Mac Mini to my Yamaha RX-V2700 receiver which outputs to my Sony XBR HDTV. I know the mini has both mini-dvi to dvi and mini-dp to dvi or hdmi available via adapters. I was thinking to go with option 1 however I was wondering what is your opinions? Is mini-display port better over mini-dvi or are they the same? Audio will be carried over optical toslink.
Option 1:
Using mini-dvi adapter to dvi: Connect Dvi-Hdmi cable to receiver and output audio with toslink adapter.
Option 2:
Using mini-dp adapter to dvi or hdmi: Connect Dvi-Hdmi cable to receiver and output audio with toslink adapter.

So our church just purchased a nice refurb iMac to use for media presentations during weekly worship services. We have a projector with a VGA cable, so I bought a mini display port to VGA adapter from apple so that we can connect our shiny new iMac to our big screen.
However, when we attempt to connect our VGA to our adapter, they don't fit together properly. It's like the screws on the VGA cable aren't long enough to screw into the adapter...thus, the cable won't stay connected to the adapter (it just falls out).
Someone suggested getting an S cable to replace the VGA cable, but Apple tells me there's no adapter to link the S cable to the iMac. I'm absolutely clueless...surely there is a way to connect my wonderful new iMac to the big screen.
Any ideas?

I saw this at wikipedia: Auxiliary channel can be used for touch-panel data, USB links, camera, microphone, etc. [URL] So is it possible to have an extra USB via the mini display port? only one USB port is absolutely inadequate.

Ok, yes I've searched but I'm a little unclear. I have a Macbook Pro the most current version (matte screen!). I need to be able to get RCA/composite video out for presentations but would like to also have DVI capability. Can I go mini-display port to DVI using this adaptor and then go DVI to RCA using this adaptor [URL[? My question is because I know there are different kinds of DVI and my understanding is that the current MBP uses DVI-D which I wasn't sure would work in this kind of setup. This was so much easier when Apple just made the correct adaptor... Anybody ordered from monoprice.com? I've seen it mentioned in a few posts and their prices are much lower than Apple's...

I have a sort of strange question, I suppose, about the MacBook Pro and Mini DisplayPort.
First of, the only reason I am considering to buy a 17-inch MacBook Pro is to be able to watch HDTV and HD Movies, I realized that with the "HDMI output using Mini DisplayPort to HDMI Adapter (optional)", it could be possible to just use my current 23" 1080p LCD flatpanel.

I see Dell and HP monitors with Display Port. Is this the same thing as what Apple uses only with the terminology slightly changed?

For anyone wanting to use their Mini Display port connector on their 4870 with a panel that has the standard size display port connector, I've found a source for a cable that works perfectly. It has the mini display port on one end and a full size display port on the other. Cost $19 bucks shipped and works like a champ. The cable is nice and compact, thinner and more flexible than my DVI cable. I'm quite pleased! ( it's the little things.... )
Here is the cable I picked up: Mini Display Port to Display Port cable
