Apple DVI to VGA out adaptor

Hi All,
I got an Apple DVI to VGA out adaptor and I have a Radeon 9000 video card with ADC and DVI output, the thing is that when I plug that in, it sees it as a VGA output, but when I connected the other end to an input on my tv, it displays nothing and when I click DETECT DISPLAY, it closes the tv connection and I am back to one display..
Now I also have a Radeoan 7000 PCI card with VGA, DVI and S-Video out and when I connect that same adaptor, it now says Televison and works as it should... Now my question is the DVI output is different on each card or is it PCI and AGP slot acts differently or do I just have a bad DVI output???
thanks and I aplologize if this is NOT the forum for this question...
Johnny

The DVI connection should work, but some displays with multiple input have trouble after the display or computer sleep. I think the display sees no signal on the computer port so goes to checks the other port. When the computer wakes, the display may be switched to the wrong port. The computer, may, then, think there is nothing connected, and turn off the video. The display comes back to the correct port, but sees no signal, and switches ports before the computer has a chance to start the video. A properly designed display would send connected signals on the DVI port while it's looking at the VGA port, but some models never recover properly from sleep with certain computers.

HT3382 DVI to VGA adaptor with Apple Mini

I have a slightly older Apple mini and would like to connect it to my TV, which only has a VGA port. Which adapter should I use? The "Apple DVI to VGA adaptor"?

Nvidia 7300GT card compatible with Apple's DVI to VGA Adaptor?

To rephrase, is the Mac Pro's stock Nvidia 7300 GT card able to support the Apple DVI to VGA connector which would allow me to connect a Viewsonics CRT? And will that card also allow me to connect a second CRT for dual monitors?
A temporary setup for a few months until I buy new Apple Displays...
Many thanks,
John

The card used with the adapter allows use of standard VGA monitors. There is always the chance that it won't, due to some irregularity, but I doubt it. Many have posted using VGA monitors and having no issues. Apple issues the adapter for your type of scenario.

Using DVI to VGA adaptor with HDMI to DVI port on Mac Mini Server

Hi - I couldnt find anything on this, so I decided to post a new topic. We just recently purchased a Mac Mini server at work for iOS development. Before we launch in in one of our data centers and start remoting into the system, we need to conduct basic setup on the system.
For this, we pulled out an old stock VGA montior we have around the office, and found an apple DVI to VGA adaptor (http://i51.tinypic.com/2mzb4lc.jpg)
The problem is, the pins dont exactly line up... on the DVI to VGA adaptor there are 2 extra pins above and below the horzontial pin on the left hand side (http://i52.tinypic.com/2mxhg1j.jpg) that do no exist on the Mac Mini HDMI to DVI adaptor (http://i53.tinypic.com/2ywesrp.jpg).
Ive checked other converters and it seems that all of them are setup the same way, with two pins above and below.
Has anyone else had to deal with this issue? I really dont want to go and buy the Mini DisplayPort to VGA adaptor for one-time use.
Thank you!

Welcome to  Discussions!
What you are seeing is the difference between an analog and digital DVI connector, as DVI as a specification can provide both types of signal, depending on implementation. When used in a mode where only one or the other type of signal is provided, the different connectors prevent a mismatch. VGA being analog, the DVI to VGA adapter is using an analog DVI connector. The other connector you are dealing with is a digital only connector. HDMI is digital only, hence the HDMI to DVI adapter being digital only. Thus you can not adapt from the HDMI port to VGA with just passive adapters, you would need a conversion device between. It would be cheaper and more effective to use a Mini DisplayPort to VGA adapter.

Using a VGA monitor with Mac Pro: DVI to VGA adaptor cord & X1900 card

I will be purchasing the MacPro with the ATI Radeon X1900 XT. However, I want to continue using my dual Viewsonic CRT screens till the end of the year until I make the leap to a new LCD display. I know Apple sells a DVI to VGA connector and in fact I believe it to be included as an accessory.
Here is my question:
The graphics card I am buying (the X1900) is designated as a DUAL LINK DVI. The Apple DVI to VGA adaptor cord has a DVI -I SINGLE LINK male connector. Will this DVI-I single link connector properly mate to the female dual link connector on the X1900 graphics card? If it will, I'm probably in business. If it won't, does anyone have an idea for a workaround?
Many thanks, John

The DVI to VGA adapter works fine with the Radeon X1900XT (and the Geforce 7300GT and the Quadro FX4500).
The DVI to Video adaptor works on the Radeon, but not on the two Nvidia cards.

How do I connect my Apple DVI port to a VGA now there is no adapter available

I have a MacBook Pro (15 inch, early 2008) which I use at my camera club for connecting to its projector. My Apple DVI to VGA adapter clearly has dodgy internal connections leading to a variety of colour casts. Although only five years old, this adapter is no longer available, which seems an absurdly short time to carry spares unless, of course, that is the life expectancy of a MacBook Pro. I had only used this adapter half a dozen times before it went on the blink, to much crowing from the Windows crowd. What am I to do?

Welcome to the Apple community Jojoprince.
What exactly are you trying to do, you can't access the Apple TV system from a computer.

DVI-to-VGA adapter disabled on HDMI-equipped monitors?

Can anyone with an Apple DVI-to-VGA adapter on a Core Duo or Core 2 Duo (both at 10.6.8, currently and probably forever) still connect to a second monitor if the monitor also has an HDMI port? I could until early 2011. From 2008 to 2010 I could connect to every VGA monitor through the DVI adapter.
I thought the DVI-out on my MBP died but got a newer MBP and it, too, doesn't work on any HDMI-equipped screens. Both computers and all my DVI-to-VGA adapters work fine on monitors without HDMI. Yes, I rebooted. No, it's not the cables. Again, all components otherwise work in other arrangements. I am not talking about any other setups. The HDMI-equipped monitors all work fine with miniDisplayPort-to-VGA plugs (today!) from newer Macs.
Any work-arounds? Anyone have a best-recommendation on an adapter that works still?

Thanks, BSteely, I have the latest QT and iTunes already. Closing the lid seems to kick the MacBook external display into some special mode that Front Row can't display videos in. For example, you get the Front Row interface, but as you select movies/TV shows, the preview window on the left side is blank. Open the cover, and have both displays going, and you can see the previews fine (and of course, you can see the movies/TV shows play fine as well when you click on them)
Running Quicktime Player full screen works fine without Front Row in either open or closed lid mode. So it is apparently something wrong with Front Row itself.

DVI to VGA and DVI to Television

I have a MacBook PRO. Below is the profile for display. I would like to connect an external monitor and I would also like to connect my computer to Television to watch movies. Both my TV's are over 4 years old and have S-Video as well as RBG (Y/pb/ Pr) / RCA. Please advise the two different kind of adapters/cables that I need to buy to make both the functions work.
Thank you!

Based on your video card, you have an older MBP with a DVI out.
For the external monitor, you'd need the Apple DVI to VGA Display Adapter - one came as an included accessory with your MBP, but you can also purchase one from Apple, at a retail store or online using THIS LINK.
For the TVs, you'd need the Apple DVI to Video Adapter, which has both s-video and composite (single RCA-type jack with a yellow band) output. You can purchase one from Apple, at a retail store or online using THIS LINK.
Note that the DVI out is only video - for the audio, you'd need mini-stereo to RCA cable - you can find those at Radio Shack, Target, etc., or online.

Part number for DVI to VGA adapter

I have a MA206LL/A 1.66 MHz Intel duo Mac Mini. The previous owner did not include the DVI VGA adapter. I am using a DVI VGA adapter from a PC. The colors on the VGA monitor are hazy, washed out, and the letters are fuzzy. I went to the Apple store to buy a DVI VGA adapter and they were not sure of the part. I called the online Apple Store and sales again was unsure and switched me to Support. They also were confused and asked me what I thought the part number might be. I understand that the Mac Mini needs a special adapter due to the DVI connecter size. Does anyone know what the correct part number is or a source for a non-Apple DVI to VGA adapter?

The Apple Store has the functional equivalent for $19. See here:

Dvi to vga adapter?

I want to connect a 20" VGA monitor to my Powermac dual 2.7. I looked in the Apple store and here's what they had:
"The Apple DVI to VGA display adapter was specially designed to allow users to connect their DVI equipped PowerBook G4 or Power Mac G4 to an external VGA monitor or projector for 24-bit video-mirroring or dual display.. The DVI to VGA adapter plugs into the DVI port built into the new PowerBook G4 or into Power Mac G4s with NVIDIA or ATI Radeon graphic cards which feature DVI ports"
Does Apple make an adapter for a G5 Powermac, if not, any suggestions on which one and where to get one?
Thanks, Pete

Yeah, I think you're working too hard.
That one should be fine. I think you can only use one of them, as they're too wide to use one on each of the video card's ports. That's how it is on mine. Only an issue of course if you decide to use two VGA monitors.

Mini DisplayPort to DVI + DVI to VGA Display Adapter, will it work?

Hi,
I have a MBP, and I have just purchased an apple Mini DisplayPort to DVI adapter.
I want to connect it to a VGA port.
Can I buy an Apple DVI to VGA Display Adapter and connect it to the connector above.
Will that work? Any one with experience who could advise me on that?
Thanks.

This does not work, because the Mini DisplayPort to DVI adapter has a DVI-D port that transmits only digital signals. VGA uses analog signals.

DVI to AV ...and... DVI to VGA... at the same time?

A Mac Mini was purchased for use with a "student TV station" run by an elementary school classroom. It will need to output a composite video signal quite often, as well as be used a standard VGA monitor.
Except the Mini can't do this. At least not normally. Apple sells two adapters for the DVI port, and it appears that we can only use one or the other, but not both:
- Apple DVI to Video Adapter, $19
http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/6234003/wo/T26cQ NkfGcGT3Pxe2vN1uH3OqJ9/1.0.19.1.0.8.25.7.11.3.3
- Apple DVI to VGA Display Adapter, $19
http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/6234003/wo/T26cQ NkfGcGT3Pxe2vN1uH3OqJ9/1.0.19.1.0.8.25.7.11.0.3
However, if I go look around on the Internet, it is possible to find a way to split the single DVI port on the Mini into two or more DVI ports, and then plug in both adapters at the same time:
StarTech 2-Port DVI Digital Video Splitter/Amplifier, $115
http://www.provantage.com/startech-st122dvi~7STRV00N.htm
I note that this is only a single-link DVI splitter, good up to only 1600x1200. I have no idea if single or dual link matters for this application, but if dual-link is required, here is a more expensive dual-link DVI-splitter option:
Kramer Electronics VM-2DVI 1:2 DVI Distribution Amplifier, $267
http://www.internet-security-inc.com/catalog/productinfo.php?productsid=486245
The question here is... can this work?
Apple is known for doing strange things with its own proprietary hardware, incorporating hidden signalling and so forth, and I'd expect nothing less of this odd little DVI to composite video adapter.
If there's some backchannel communications going on between the video adapter and the Mini, then things may get confused if I try to split the signal and use a VGA monitor at the same time.
In a worst-case scenario, this could possibly damage the Mini, the monitor, or the adapter. Or at minimum, perhaps the video adapter won't work at all.
Has anyone tried splitting the Mini's DVI port like this?

This sounds like it could work. One restriction is that both displays would have to be displaying the exact same image at the same resolution. Since it sounds like one of the devices will be a TV, you will probably be running 640 x 480. That's a pretty low resolution to be running on a VGA monitor.
You don't need dual-link. Single link will be fine. The mini doesn't support dual link. You might want to call on startech.com and get some pre-sales information about your application. I think you are justified in your worries that the setup of this box with a mini might prove tricky. I was reading the manual for the ST122DVI and came across this cryptic note: "If you install the DDC monitor for the splitter, the rest of the monitors must be the same resolution as the DDC monitor." That sounds like a bad translation from another language to English. The mini relies on DDC (backchannel communications, as you put it) so the box needs to pass this info correctly or you will have set up trouble and would probably have to resort to a utility like DisplayConfigX or SwithRes X to manually set a resolution.

HT3235 Will generic DVI to VGA adapter work with Macbook Pro (Early 2008 Model)??

I have a 15" MacBook Pro (Early 2008 model). I lost the Apple DVI to VGA adapter for use with my projector, and it appears this older model is no longer available. Will a generic DVI/VGA adapter, from Best Buy for example, work? I wasn't sure if there was anything specific to the Apple adapter? I am supposed to give a lecture in 2 days and can't find my adapter! Any help is greatly appreciated.

Yes it will, assuming that you do not have a display like the 30" Apple Cinema Display that requires dual-link DVI.

No Apple Remote or Apple Mini-DVI to VGA Adaptor included with new MacBooks

Hi!
I just picked up a new (black) MacBook yesterday from the Apple Retail Store in Meadowhall (Sheffield). I was quite surprised to open the box and find that the Apple Remote and Mini-DVI to VGA adaptor cable are now optional items and no longer included in the package. Okay, they're not expensive (an extra £30.00 to add both of them), but I just thought I'd mention it to let potential customers know.
I have to say that I'm very pleased at the speed bump and the 250GB hard drive though (you can never have too much space). Also good to have 2GB RAM out of the box (rather than paying an extra £90.00 for the 2GB model). Excellent!

bford0001 - 15% restocking fee? Did you buy it from an Apple Retail store? I bought a black MacBook from them just under two weeks ago (a 2.2 with 160GB HD and 2GB RAM) and they let me take it back and walk out of the store without charging me anything!
One other thing I have noticed - why has the L2 cache dropped to 3MB from 4MB? I know the processor is more powerful, but doesn't that mean it would just about level out, because of the reduction? I noticed the same for the £1,299.00 MacBook Pro and that on the other two models, it's gone up to 6MB. Anyone know how this would change the performance?
