Dvi to video adapter changes shape

When I plug my DVI to Video adapter into my macbook pro, all of the displays change shape, and no matter what resolution I choose, it won't go back to it's true size. When I try a DVI to vga adapter, it works fine.

Try starting the Mac in Safe mode.

Hopefully that will result in a usable screen. If it does, go into Displays Preferences and change the resolution to what it was when you had things working properly before. Then restart normally and the resolution selection made under Safe mode should persist through the normal restart.

Mini-dvi to video adapter changing display on macbook?

I recently purchased a mini-dvi to video adapter for my macbook to be able to view photos and video on my tv. I'm having trouble with the display on my computer when I use the adapter. As soon as I plug in the mini-dvi video adapter into the computer the display on my computer switches from 1280 X 800 to 640 X 480. Attached to the adapter I have an s-video cable to my tv. The display shows the same on the tv but in black and white.
Any ideas? Thanks!

Turn mirroring off. That way the two displays can run independently from one another. The mirroring check box is in Displays Preferences under the Arrangement tab.

Apple Mini-DVI to Video Adapter doesn't fit my aluminum iMac

I previously had a 17" white iMac (pre-Intel) machine, and about 6 months ago I bought the mini-DVI to video adapter so I could connect it to my television. Worked like a charm. But I recently bought a new aluminum iMac, and the adaptor doesn't fit into the mini-DVI port in the back of the machine. It appears the adaptor and port are both male ends.
Has the port changed on the aluminum iMacs? The product description for the adaptor on Apple's website says it works with iMac (Intel Core Duo). Isn't the aluminum iMac an Intel Core Duo? I can't figure out why it doesn't fit and which cable I'm supposed to be using instead.
Any advice would be appreciated!

Hi Paul
Yes the Intel iMac [Spec's|http://support.apple.com/specs/imac/iMacMid2007.html] call for the (M9319G/A) Apple Mini-DVI to Video Adapter!

The iBook, eMac, or iMac G5 use the Mini-VGA to Video adapter.

Annoying mini-DVI to video adapter...

I've been using a mini-DVI to video adapter, mostly to watch DVD's since my PS2 broke, for about a month. However, tonight when I tried to set it up, it didn't work.
I plugged in the cable and the adaptor and the only thing that would show up on the screen is my wallpaper-- not my cursor, or the dock, or the icons on the desktop. Just the desktop wallpaper. And nothing else is showing up.
Is the port fried? Or is it the adaptor? Which is more likely/how can I tell/how can I fix it? Thanks in advance!

The desktop background is visible, so it is working, but in extended desktop mode, if you move the mouse or drag a window far enough it will show up on that display.
options:
-close the lid, when the internal display shuts off the external will become the primary display, do you have an external keyboard/mouse to wake up the computer when the lid is closed?
-Use System Preferences: Displays: Arrangement to drag the white menu bar (and Dock) to the other monitor.
-Also, in System Preferences: Displays, check the Mirror displays to force both the laptop and the external display to show the same thing.
I'm not sure how your settings got changed or what you did before, but it's possible that something reverted to a default setting if you did some software update or something.

Mini-DVI to Video Adapter

Well being a new mac users (and loving the change greatly) I decided to use my brand new black macbook to it's fullest extent and make my own Keynote presentation. Although the final result is great I need to know if I can actually get it projected up onto our big screen.
After about 5 mins of browsing the UK's apple shop I found the solution to my problems
Link
But then realised it doesn't state any support for the macbook and one of the comments says:
'Very unclear advertising regarding machine compatability. Apparently 2 types of 'mini-dvi' - both called 'mini-dvi'. This is only compatable with the most recent version of the 12" Powerbook. '
Which is leaving me very nervy about just ordering the product without confermation of it's compatibility.
Can anyone help?

Apple store links are temporary unless you have the permanent so I won't post it... but if you go to the UK store and click on Displays under Mac Accessories- the Apple Mini DVI to Video Adapter that is on that page is the one that you want. It works for my MacBook, it should work for your MacBook

The write up on the UK store may not have been updated like it is on the US Store but the part should be M9319G/A

Mini dvi to video adapter ...how does this work?

I just bought a mini-dvi to video adapter (with the composite /s-video output)
I plugged it into my tv, and I can get the desktop on my tv.
But I see only the desktop, no icons or windows etc. Do I have to setup something? Or change something in my system preferences?
I don't really get it since there came no manual with the cable.

Hi,
it is possible that the output is not mirrored, but that you have two different desktops. The one on your TV does not have the menubar etc.
But you should be able to move any open window from your iMacs screen to your TV (either over the left or right side of the screen).

Mini DVI to Video Adapter - S-Video Resolutions / HDMI

Hello,
I just got my Mini DVI to Video Adapter and I using a S-Video cable to plug to my HD LCD 32'' TV.
When I connect everything, the resolution drops from 1280x800 to 1024x768.
How can I change back to 1280x800?
I don't know but I'm kind of disappointed with the QUALITY of the video... is there any way I could improve this? Perhaps using a Mini-DVI to HDMI Adapter? Does it exist? Will upgrade the resolution and/or the quality of the video?
I've read that audio is not supported using the Mini-DVI. To be honest, I don't really care about the audio... I can use the analog. But I'm very very disappointed with the quality of the video...
Thanks anyone

Well,
Based on what you said, I should have three options:
A: MacBook -> MiniDVI to DVI Adapter -> DVI to HDMI cable -> TV with HDMI input
C: MacBook -> MiniDVI to DVI Adapter -> DVI to DVI cable -> TV with DVI input
B: MacBook -> MiniDVI to HDMI Adapter -> HDMI cable -> TV with HDMI input
What should work best?
My TV does not support DVI input, so that's kind of narrow it down, right?! Leaving options A and C.
I don't have any of the adapters. In both ways I'll end up having to buy stuff. Which is less expansive?
Thanks in advance
Cheers.

Will Apple Mini-DVI to Video Adapter device work on HD TV's?

I have a Macbook. Will using just the Apple Mini-DVI to Video Adapter work for me if I have and HD TV so that I can watch movies from the Internet on the HD TV screen? How good will the quality be compared to watching on the Macbook itself? And I've noticed how short the chord is for the Apple Mini-DVI to Video Adapter. Will I have to buy another chord to make it reach the back of the HD TV? Thanks.

As it happens, I just bought the mini-DVI to video connector for my wife's Macbook (C2D) yesterday. I am in Australia (which is a PAL country), but I didn't see anything on the device or the packaging which indicated it as being PAL-specific. In fact, in Display Preferences when it is connected to the Mac and TV and in use, the panel relating to the TV output (which is shown by the Mac on the TV screen) is where you select between PAL-50Hz and NTSC-60Hz, so I'd guess it is a single worldwide device, rather than their being separately-manufactured PAL and NTSC variants of the connector.
Anyway, on the back of the top cardboard part of the packaging is a picture of the connectors (because you cannot really see the pins in the Mini-DVI connector itself when packaged, due to an opaque plastic "keeper" over the end of the plug).
To reconfirm what is said above, the pin configuration on the mini-DVI port on the MacBook and what you need on the Mini-DVI connector is a horseshoe or "U" shape. I don't remember if any specific model of Mac is listed, but I believe as long as it is that U-shaped connector you'll be fine with the same connector kit.
The "mini-VGA to video" connector is not what you want for a MacBook; mini-VGA is not "U"-shaped inside, but rather two rows of pins in "II" configuration (even though the outside dimensions of mini-VGA and mini-DVI look very similar).

Will the Apple mini DVI to video adapter work with a macbook? What to Buy?

I went to my local Apple Reseller and asked for a mini dvi to video adapter to use to connect my macbook to a tv using either s-video or the yellow RCA cable. I was told that they only had the one that was for an ibook and Power book and that this would not work with a Macbook. I would need a different one. Is this correct. If so, what do I need? I have looked on the online Apple Store and cannot find anything that fits this description. They only list one type of Mini DVI to tv adapter? I just want to be able to connect my Macbook to a TV.

Does DVI to Video adapter send both s-video and composite simoutanesly?

Hi,
I´m wondering if you connect the DVI to Video adapter on the new MacMini (DVI to s-video+composite), does the Mini send BOTH s-video and composite at the same time?
If connected to TV and projector, I want to see both simotanesly, not neede to change something in the setup...
The both having same resolution I guess is a must!
Regards,
Pat

Yes, many think, but i´ve havnt heard anyone whoose sure?! Can´t be such a odd thing, connect a Mini to two displays at same same time...

DVI to Video adapter TV

My dvi to video adapter worked fine at first, when I connected to my CRT TVs. Now it is in black and white and the vertical hold keeps flipping. Tried it on two TVs same results. Tried rebooting same thing after the logon page. Help please

Apple DVI to Video Adapter performance issues in Lion

I'm an active Apple DVI to Video Adapter user for a couple of years already and everything worked perfectly well until I've upgraded to Lion.
Everything on my TV screen is lagging now, even mouse pointer, and there is no change to watch any movie like that.
Does anyone have the same issue? Maybe someone could give me an advice of what could I do in order to improve graphics performance on TV screen using Apple DVI to Video Adapter? I'm using late 2007 MBP with 8600M GT video adapter.

I am having the exact same problem. I have a late 2007 MBP. I use it everyday where I teach. I use the adapter to project on a large white screen using S-Video. SInce the Lion update, it is very slow and has even completely crashed my computer a few times. I realize the MBP is getting a bit dated, but the difference between Snow Leopard & Lion is remarkable.

Apple's DVI to Video adapter broken in Mavericks

Good Day,
I've been monitoring this community forum as a guest only, because IMHO registering with anything over the Internet is equivalent to giving up a piece of your soul, but I could not find anything that would help my unique situation since upgrading to Mavericks. So here I am, and here is my situation.
I own a late 2007 15" Macbook Pro running 2.4 GHz Intel Core 2 Duo. It's a Vintage brand. The last known OS X I had on it was Lion, and it worked beautifully when I could output my video display using the DVI to composite/S-video adapter hooked up to an analog "tube" TV. I could watch DVDs, YouTube vids in expanded mode, I even figured out how to watch iTunes movies on the TV... at the sacrifice of my computer use. Basically, I needed Mavericks' independent display feature.
But I couldn't have it.
After downloading Mavericks overnight and installing it the next day, My computer would not boot up. It stuck at the Apple logo screen with the loading gear continuously rotating upon itself until it became opaque (too involved too explain). After having service done, I isolated the problem to the adapter. Not only could it not boot up when plugged in, but it also didn't display when plugged in while powered up unless you hit the Mirror Display key. Further experimentations involved using DVI to DVI cables, DVI to VGA cables, and they worked fine.
I will not upgrade to a new HDTV or a new Macbook because everything I have still works, and I can't afford a new setup because jobless. At this point, I don't know what to do. Does Mavericks just plain not want to recognize my DVI port? Is there another way to hook this old laptop to an old TV with the equipment I already have?

Well, my proposed workaround, involving two adapters, does work, and indeed works quite well.
1. Apple's DVI to VGA adapter, plugged into the Mac on one side, and on the other side:
2. Male to male VGA gender changer, which plugs into:
3. VideoSecu PC to TV converter with both S-video and composite video outputs, QVGA2TV 1L7, which costs about $20 on Amazon.
I use the S-video output, which in fact goes to an S-video balun, and from there via a Cat5 cable to another balun upstairs where my TV is. (I have a separate balun for digital audio into my DAC upstairs.) After some tweaking of the VideoSecu, I got a picture that is noticeably better than the one I got with the Mac DVI-to-Video adapter which I had been using before upgrading to Mountain Lion.
So, yes, the additional adapter adds to desk clutter, but heck, since Apple has never fixed this problem with Mountain Lion, it might never get around to fixing it with Mavericks, so this solves the problem here and now.

Choppy Video Out when using DVI to Video Adapter

Hi, I just bought the "Apple DVI to Video Adapter", plugged an s-video cable between the adapter and my tv, and then connected the adapter to my computer. The TV immediately recognized the computer, the resolution of my computer display immediately changed to a lower one, I launched DVD player and put a disc in. I was really happy with my new Adapter!
But then, I noticed that the video in the TV was choppy, not all the time, but sometimes throughout the movie... The funny thing is that the video in the computer display is not choppy, just in the TV... I quit all applications in my mac, but that didn't help....
Any help would be really appreciated!
I have one of the newer 15" MacBook Pro's, with 4GB of RAM, and 2.5 GHZ processor.
Thank you very much for your time,
Daniel Vogel

Concerning your question, "if only i knew the the correct entries for a custom displayconfig x timing," I think I can answer that one for you.
It sounds like you have other Macs at your disposal that are correctly driving the TV you are trying to drive with the Intel mini. In that case, install DisplayConfigX on one of those computers and while it is running the TV at the desired resolution, click on the "Card" tab in DCX and then click on the "+" symbol at the bottom right corner. This will open a window in DCX titled "Resolution details" and you will see all the detailed information of the timing you need to enter into DCX on the Intel mini.

Mac Mini with DVI to video adapter REFUSES to display on TV!! Please help!!

I purchased an apple DVI to Video adapter - which says for Mac mini and power mac G5 on the package. However not matter what I do, I can't get a picture on my TV, I have tried on 2 TV's and I get nothing but blank screen on both, with occassional grey flicking.
I thought maybe the adapter was faulty so had it changed, the new one shows the exact same behaviour. I have started up in safe mode, with the TV connected and still nothing, I have reset the PRAM and still nothing. Trashed the windowserver plists - and still nothing!!
I have searched through the forums as much as I can and can't find any answers.
Someone please help me out and tell me what I'm doing wrong.
Thanks very much.
Naj

Hi Thesserax,
Thanks for your reply, however I have already tried your suggestions - my tv's do not let me switch manually between PAL/NTSC, and I am definately on the correct channel.
I also tried connecting it to the TV and VNC'ing into it to try to change the resolution, however I although I see the correct CRT resolution opions i.e. 800x600 and 1024x768 only, I notice that I don't see any tv specific options such as overscan, and that the rates are stuck at 60Hz (NSTC) - I am in europe so the tv is PAL 50Hz and the adapter is also labelled PAL.
Any other ideas, please?
Thank you
