Help with DVI adaptors

I own a powermac G5 tower with standard DVI female sockets on the back. My Apple Cinema Display has what looks like a male DVI, but it is a bit wider (more pins) and has symmetrical rounded edges, not tapered like the female socket.
Can anyone please explain the difference between these two types for me? and whether there is an adaptor which will help me out?
Many thanks

That oval connector is called the ADC and this is the adapter you need:

Oops. Malcolm beat me to it. And with better advice. Check and make sure you don't already have the right connector on your G5 as Malcolm explains.

ATi Rage 128 PRO with DVI adaptor

I got a PowerMac G4 with Ati Rage 128 Pro which has a VGA and a DVI port on it
I would like to know if the DVI port going to work with the Apple DVI to Video adaptor?
I know the postage of the adaptor said it is only for PowerMac G5 and Mac mini but is there any differences between the DVI port on the ATi Rage 128 PRO and those on G5 and Mac Mini?
Is there any other solution that I can output the display to a TV with s-video or RGB?
Thank you so much!!
Cheers,
Lawrence

It's not the port, but the card that matters. The conversion to video is done by the card. The adapter just sends the output to the correct pins. I think the only cards that work are the recent ATI cards. Yours is probably too old. ATI's web-site doesn't have any information on it.

You can get a newer graphics card or use a VGA to Video converter.

There are other, cheaper, ones.

Apple Cinema Display with DVI to VGA graphic adapter... HELP

A friend of mine has a PC (Windows XP based) and is using the Apple Cinema Display. Since his graphic card has both vga and dvi slot, he can plug the monitor to DVI and got it working, but when he tried to plug it into the VGA slot using DVI to VGA converter, it did not work. Is there a need of special converter or adapter?

Hi royz86,
To run a DVI display off a VGA output, you need a rather expensive converter box. These converters vary in performance, reliablility and application possibilities and certainly don't compare with using a native DVI output.
Your friend was probably trying to use a DVI to VGA adaptor (which won't work "the other way around"). It works by grabbing the analogue signal that is included in a DVI-I output and setting up a VGA output that way. These don't work with DVI-D outputs, by the way.
Cheers!

17" MacBook Pro to 30" HD Display issue using Mini DisplayPort to Dual-Link DVI Adaptor.

Just replaced the Western Digital hard drive on my MacBook Pro with a SSD now running Lion 10.8.2, (updating from Snow Leopard latest version).
I have a 30" HD Apple display monitor and very much love using it.
The issue.
The MacBook Pro will only allow the 30" Monitor to display its top resolution when the unit is closed, when it is open it shows either 2 screens or mirrored screens depending upon the settings, but not at the top resolution capable by the monitor.
Now, when I was using Snow Leopard on the previos hard drive, I could close the MacBook Pro and put the computer to sleep also putting the 30" Monitor to sleep, I could then wake the computer while it was closed with my external keyboard and the screen would wake showing the FULL resolution possible on the 30" Monitor.
Then I could open the lid of the MacBook Pro and the screen would stay black allowing ONLY the 30" HD Monitor to be used effectively as a desktop computer, without the complication or need to display 2 screens or mirrored screens but most importantly the fans wouldn't need to work overtime due to the MacBook Pro being closed cutting off vital ventilation through the 2 air ducts to the left and right of the keyboard.
For some reason I cannot do this with Mountain Lion, the compluter needs to be closed in order for the 30" Monitor to display top resolution, and the fans are working overtime and the unit is getting really hot.
My concern is that the MacBook Pro will overheat, the screen will be damaged as the MacBook does get exceptionally hot when running design and audio packages, even Adobe Flash sets the fans off, and lastly the computers speakers are muffled which is more of a moo point.
If anyone could shed some light or offer a solution I would be most appreciative.
My specs:
MacBook Pro 17" Mid 2009 3.06 Intel Core Duo, 8GB 1067 MHz DDR3, NVIDIA GeForce 9600M GT 512 MB, OS X 10.8.2 - connecting to an Apple 30" HD monitor with a Mini DisplayPort to Dual-Link DVI Adaptor.
Thanks

Thanks for your quick reply! I want to think I'm not technically challenged, but... are you saying to go from minidisplay on macbook directly to the firewire in the back of the monitor? Or should I try to attach it to that ugly bunch of cables at the end of the monitor cable (dvi, usb, firewire and the power adapter thingy)? Either way, it seems like I might need yet another cable? Like Mini-display to... ?
I feel like my mother asking these questions... At any rate, when I called the guy at apple support last time he acted like it was a Miracle that I had anything on my cinema display at all if I had a minidisplay cable plugged into the thunderbolt port. He said that didn't work (but obviously it did, at least a little) I DID get a picture, it just wouldn't display at the 2560x1600 resolution. More like 1680xsomething. fuzzy and big. I want my pretty picture back.
Thanks so much for your help.

"miniDVI-DVI adaptor" + "DVI to VGA cable" can't detect LCD TV

Hi,
I just bought a "miniDVI-to-DVI" adapter, and then a DVI-to-VGA male-to-male cable to connect my MacBook to Viewsonic 19" monitor but my MacBook didn't detect the 19" monitor. (This 19" monitor has only VGA but no DVI input!)I tried it on my friend's 32" LCD TV but it couldn't work too.
Then I tried to connect my MacBook by using "miniDVI-DVI" adaptor + "DVI-DVI male to male" cable to DVI socket of my frind's 32" LCD TV. It worked! So I think it's not the problem of the "miniDVI-DVI" adaptor.
I worried that it's the problem of the "DVI-to-VGA" cable so I went to the shop to exchange another new "DVI-to-VGA" cable. But my MacBook still couldn't detect all these 2 monitors via VGA socket.
Can anybody help me? Please advise! Thanks!

Hi,
Thanks for your response.
The shopman told me that "miniDVI-VGA" adaptor was out of stock, only "miniDVI-DVI" adaptor was available yesterday. At that time I thought I had to buy a connecting cable also (no matter it's VGA-VGA or DVI-VGA cable).
Since my friend has a DVI-DVI cable, if I buy this "miniDVI-to-DVI" adapter I may share my MacBook with his 32" TV too. So I bought these adaptor & cable.

No Native Res with DVI/HDMI but OK with DVI/VGA cable on Loewe 32" LCD

Hi there, I am a little confused about connecting my mini to my Loewe Individual LCD TV and coudl do with some help.
I purchased a DVI to HDMI cable at enormous cost because my experience of DVI versus VGA is like night and day and I wanted to have the best possible connection to my HD TV.
The problem is that when I connect the mini with the DVI/HDMI cable the native resolution of my TV is not available. (1366x768 or thereabouts) The only resolutions to choose from are 1920 x 1080? and 1024 X 768. Using overscan on the 1024 fills the screen correctly but looks all stretched.
Instead I connected with a VGA cable and the correct resolution is automatically detected immediately and there is no problem at all.
I am a little bit confused as to why it works fine with VGA but not with DVI/HDMI. The VGA connection looks OK but why compromise when you shoudln't have to?

First of all, I am far from an expert but as I said, from my experience and after reading a LOT, HDMI cannot support 1366x768, that is why the TV goes without picture if you try. Why? I don't know.
Now, DVI is almost like VGA, both are analog, and can support 1366x768 or 1920x1200. But since you go from DVI output from the Mac Mini to the HDMI cable, screen goes black, blue, etc, res no supported.
That is why some people don't have problems with the powerbook and their HDTV's, and then they try with the DVI-HDMI adaptor (normally with the mac mini) and it's no good.
The thing is, you can get 720p, 1280x720 but with overscan, so with DisplayconfigX you go from:
1280x720 (720p)
128 Front Porch 10
80 Sync 5
200 Back Porch 15
1688 Total 750
to
1240x680
128 Front Porch 19
80 Sync 5
240 Back Porch 38
1688 Total 750
for example, with this setup you get the image cut to a minimum.
As you can see the totals are in both cases 1688 750. As soon as you don't respect this totals, like in this example:
1366x768
28 Front Porch 5
80 Sync 5
40 Back Porch 15
1514 Total 793
your TV won't be able to dispay the image. But with VGA the totals don't matter!!!!, that is why it works with one cable and not with the other.
Apple should update the Intel graphic card drivers, maybe that would help.

No longer able to use single link mini DVI adaptor

I have a 27" iMac, model 11,1, and my second monitor is a 27" ViewSonic that was hooked up via the short-cable mini-DVI adaptor. Not long ago I started having odd slow-down issues, almost system hangs, and as it turned out the cure was to unplug the monitor. Odd, I know.
Anyway, I thought the adaptor might have gone wonky and the only spare we had lying about was a dual-link one, with the long cable and the USB plug added. That worked fine, so I figured all was solved.
Well, we wanted to use the USB-enabled cable elsewhere, so I swapped the adaptor out for a brand-new single-link one. No signal at all. The Dispay Settings panel on the iMac detects the ViewSonic monitor perfectly, but that monitor won't display anything at all (except the "No Signal" message). Then we tried the short cable on a different iMac, same model, and it works fine there. For now I seem to be stuck with the dual link cable.
For some reason my particular iMac does not like the single link DVI adaptor, and I'm baffled at why since there seem to be no other symptoms of problems.
Has anyone else ever encountered something like this, and have you any idea what the deal is?
Many thanks in advance!

DVI Adaptor Failures

I have been having numerous failures of DVI display adaptors with my MacBook Pro: OS 10.7.4, Late 2011 Model, Intel HD 3000 384 MB Graphics Card.
The Mini-DVI Adaptor will work for about a week, then fail. This is the third unit that I have had to swap out. In all cases, after working properly for about a week they have failed. I have attempted to remove the adaptor from both the mac and the cable, turned off the ViewSonic LED Display etc and various combinations of this. The end result is that the Mac ultimately fails to recognized the adaptor, there is no screen flash when connecting the adaptor and no signal going to my external display.
Is this a problem with my Mac? Could the Mac be causing a failure of the display port?
Any help is appreciated as this is very frustrating (fortunately Best Buy is 300 yards from my office and they have been very supportive).

Sorry, I wrote that post yesterday, but there was no time posting it. In the mean time, a new topic has been started: http://discussions.apple.com/thread.jspa?messageID=2305472#2305472

ADC to DVI adaptor

I just bought a new Macmini, abd want to use it with my OLD monitor (the first flat panel Apple offered). I'm told by a genius at our local Apple store that I need an ADC to DVI adaptor. Someone on this discussion site said I need to use an adaptor with a brick. Is this so, and where do I find one? I googled the adaptor, and it only showed me adaptors with no brick. Any help with this would ne appreciated.

Dear MaryAnn,
I think it makes more sense at this point to bid a fond farewell to the old monitor if it is ADC.
The problem is that Apple's ADC monitors ran power, video and USB through one cable. It's the "power" side of the equation that requires the brick; the monitor can't get power from the wall like a regular one does. The Apple genius was wrong. Those people seem good with current gear, but are commonly weak on older equipment made before they had to use underarm deodorant daily.
Original Apple adaptors are sky-high in price:
M8661LL
I recall there being third-party adapter like Dr Bott but they are also discontinued and scarce. I looked for one about two years ago and they were already around US$100.
For $100 you can get a nice flat-panel monitor and, for $150 you can get a really nice FP monitor.
I am an advocate for keeping old technology in service and out of the landfill, but ADC has to be scored as an Apple failure in the long run.
EDIT: Forgot your monitor was probably newer than the pre-1998 equipment this forum served. You may want to look through this part of the forums where older displays are discussed:
Older Displays & Monitors
to see it there are any better workabouts.

Dvi adaptor

Just got the macbook, had the ibook before, and it was connected to the tv with no probs, now i have bought the mini dvi adaptor for the mac book and i have tried with svideo and with rca cables and all i get on the tv is grey lines. the display is not showing any tv monitors on the finder so i am stuck. any help will be greatly appreciated,
thanks,

You might choose to "Mirror Displays" so you can clearly see the same thing on your MacBook's screen, since you can't really see the Displays System Preferences window on the TV. Then you should be able to see if you can see the NTSC or PAL options are available. They won't normally be available for your computer screen. It's possible that your MacBook thinks the video adapter is just DVI or VGA adapter. It's possible it's defective. You get 90 days of free technical support from Apple with your new MacBook, maybe they can help determine if it's a problem with the adapter or your MacBook?

CPU whine with DVI and line out/DVI removed whine not in line out?

I have noticed that when using headphones or the line out alone I do not hear the whine noise. The whine noise is still active, in other words, I can still hear it coming from the keyboard. But, it is not transferred through the line out or headphone jack. THIS IS BEFORE I DO ANY TRICKS: mirror widget etc.
But, if I plug in the DVI adaptor and utilize the line out/headphone jack, the noise now appears. This means if I am running my laptop to do a presnetation, the noise will appear through the sound system. However, if I don't use my laptop for video and use it for audio only, the noise is not THERE!
Of course, I can use the tricks and it will eliminate it. But this leads me to believe that something is related? The DVI connection with the entire mother board....or something. Any comments? Please help

I agree. I never use line in/out of the computer for professional work. I had PCI expansion chassis doing that type of work when using the PowerBook, and am eagerly awaiting Magma's upgrades which will come soon per their emails. However, I do use my portable computer to teach and to present research, at which point lugging a full blown professional system is not an option. In some cases, it would be nice to use the line out while presenting, without having to carry additional equipment.
In any case, the problem does exist and is one that shouldn't exist. The fact that there are workarounds does not "fix" the problem or for that matter acknowledges it. Apple should acknowledge the problem and replace the faulty parts in the machines affected. I bet that if it was the other way around, say plugging something in the headphone jack would affect the screen resolution, people would be all over the place, and the solution could not possibly be, "just hook an external monitor and it will work fine".
In the meantime, I am just trying to find out if this is a widespread issue or not to see if it makes sense to return the machine, with which I am absolutely happy otherwise even with the other problems reported.

Mac Mini with BenQ W100 Projector (No signal with DVI Dual cable)

Hi all, just bought a Mac Mini Intel 1.6ghz. Also have a BenQ W100 Projector which have been using for some months with a PC. Now comes the problem! I have bought a DVI-DVI cable (Dual link) and plugged the Mac into the Projector and NOTHING APPEARS! No source found at all. The input on the projector is DVI-I according to the BenQ website.
Question is, am i using the right cable? Is the Mac Mini even compatible with this projector? Nobody seems to know, even BenQ!!
Thanks for any help
BEN

Hi, FYI this is the cable I have. Strangely it only references HD sources and not computers on the description? I would note that PC World (where i bought it from) have shown this cable operating on a PC unit and LCD monitor so im presuming its nothing to do with the cable?)
http://www.amazon.co.uk/Belkin-PureAV-Digital-Video-Dual-Link/dp/B0003057GO[/URL]
I used a VGA to DVI cable when the PC was running on the projector. which shows a picture no problem. I tried using the DVI/VGA adaptor that came with the Mac then plugging the VGA-DVI cable into it. As i say no picture just a flicker now and then.
I have tested Mini and he works fine on a LCD TV using the VGA/DVI adaptor and a standard VGA-VGA cable.
I guess i will exchange the cable and see what happens!

Using External monitor with DVI kills wireless connectivity

I recently purchased a BenQ G2400WD 24" 1920x1200 monitor, for use with my May 2007 GMA 950 2.0Ghz. Macbook.
Upon receiving the monitor, I immediately plugged it in to my Macbook, using the Mini-DV to VGA adaptor I already had, for use with projectors. The monitor was good, but a bit blurry and not too sharp, due to the analog signal. So I ordered a Mini-DVI to DVI adaptor. When it arrived, the improved picture quality was immediately apparent.
However, as time went on, I noticed my wireless connectivity was getting terrible. Extremely slow Safari page load times, and upon going to Terminal and pinging my router, I would often get response times of 21000 milliseconds, or worse! I did a lot of research, on router firmware, on wireless connectivity, etc., but to no prevail. Then, on a whim, while continually pinging my router, I removed the DVI adaptor from my monitor. The ping instantly dropped from tens of full seconds to just a stable 0.4 milliseconds! Using my VGA connection resulted in no worse wireless connectivity than without it, but upon plugging in DVI and stressing the connection a bit (i.e. downloading a large file), the connection went bonkers. The pings also immediately jump from 0.4 milliseconds to a range of 1-4 milliseconds, regardless of any "stressing".
I have done numerous research, including searching both here and on other discussion forums. It appears this problem with DVI connection is fairly common, but with no resolution so far. Any help would be great!
A few important notes:
-Both ends of both my VGA cable and my DVI cable are shielded.
-I have tried numerous channel changes of my router, to no prevail.
-While using DVI, EVERYTHING works well except the wireless. So the monitor isn't too demanding for my computer.
And I hope my thorough post didn't scare you away!

I have this same issue with the dvi and wireless disconnect. I am using a samsung 214T. I am glad to know i am not the only one seeing this, because it is kind of one of those things that is hard to believe. Anyway, I am also curious what kind of routers people have who are experiencing this issue. I am using a wrt54GL with tomato firmware.
Also, In addition to the disconnect, my picture quality on my monitor gradually degrades over time...starting with what looks like snow flecks. After waking from screen saver, sometimes it is full static. Turning off and turning back on the monitor clears the static away.
I can use another samsung 19in monitor with dvi without any problems.

Mini dvi to hdmi adaptor vs. mini dvi to dvi adaptor

Do the mini dvi to hdmi adaptor works? I notice a lot of them for sell on ebay, but none at apple store. Does apple not recommend this setup? Most of the forums address the mini dvi to dvi adaptor to dvi to hdmi cable set up. I can not find anything that clearly says you can use the mini dvi to hdmi adaptor and just connect a regular hdmi cable to get video from a macbook to tv.
BTW My LG tv model 42PC3D (link to manuel below) says that the HDMI cable supports computer connection.
http://us.lgservice.com/index_b2c.jsp

There are reports here that non Apple mini DVI-->whatever cables don't work correctly connect to a MB. That said, if the cable is cheap enough, give it a shot. I just looked at the mini DVI-->HDMI cables on eBay and they all look "short" and for most installation, will require a longer HDMI-->HDMI cable.
So, unless the price of a DVI-->HDMI cable is a lot more than an HDMI-->HDMI cable, why not go with the standard Apple mini DVI-->HDMI cable? However, if you already have the latter, I can understand why you might not want to buy the former cable.

Mini DVI - DVI adaptor

This may be a stupid question but...
I have to do a presentation and need to connect my MacBook to an external monitor for the first time. I was told that they have a fifteen pin video cable to plug into my computer. Is a Mini DVI - DVI adaptor what I need?? Also, do they have these at Best Buy?

Hi,
Yes, you need an adapter. I was surprised that the Macbook comes with that strange little non-standard video connecor. I'll give Apple a criticism on this point, requiring me to both spend additional money for a converter dongle and have yet another thing in my presentation kit to get lost or accidentally left behind when I use my Macbook in a lecture hall.
I'd say, fine, go ahead and put the oddball connector on there, but also be presenter-friendly and give us a standard VGA connector. Every media-enabled lecture hall I've encountered at a university or hotel has a VGA cable hanging off the podium.
Be sure you get the correct adapter. There are three types: DVI, VGA, and S-video. They're all about $20 each from US suppliers. I'd recommend going to a computer store to be sure you get the one you want. Web sites often don't have adequate descriptions ofthe adapters to be sure you order the one you need. That's over-priced for what you get, but you have no choice.
This reminds me of the old powerbooks that had that weird mini-DIX connector instead of an RJ-45 Ethernet jack the rest of the civilized world was using.
