Does the DVI-to-video adapter work on 8600GT macbookpros?

I have the newest 15" macbook pro (rev 3,1) with the 8600GT nvidia gpu. I bought the dvi-to-s-video output adapter on the online store, and I cannot get it to work - all I get is scrambled looking video, like I'm trying to watch a premium channel I haven't paid for. Has anyone else gotten this to work on the same hardware? And, if so, what are your display settings? I can't get it to work on either the mac or windows side, and I have tried just about every resolution/refresh rate available on both sides.

I've wondered about this myself. The product information page states "Use the DVI to Video Adapter to connect the DVI port on a Mac Pro (with ATI X1900 XT), MacBook Pro, or Mac mini to any S-video or Composite enabled device," which implies that you can use it. Except that it had the same language prior to the release of the SR MBPs with the Nvidia chips, and they clearly indicate a need for an ATI card with the Mac Pro.
I would give a call to Apple (or to an Apple Store if there's one close, just press 5 at the prompt to get a live person).
Please post back what you discover!

Any noticable signal loss with the DVI-to-video adapter?

Hi, there. Would any of you happen to know whether there's an appreciable signal loss when converting from DVI to, say, composite video via the DVI-to-video adapter? I'd like to hook my MBP up to an HDTV (when I eventually get one), and I'm wondering if going through the adapter would produce a degraded picture for DVDs, compared to a direct digital connection from a DVD player to the TV.
Actually, I'm wondering the same thing about the audio connection. Any loss in audio quality when using an adapter to connect the MBP's mini-jack to an HDTV or receiver?
Thanks much.

ragamoffyn,
While there's no "signal loss," as such, there is a considerable loss in signal quality. However, you're over-thinking this...
HDTVs accept HDMI connections, and your Macbook Pro has a DVI output. The ports are dissimilar, but digital video signal is the same. In other words, you would simply use a DVI-to-HDMI cable. In fact, many HD cable boxes (mine included) still have a DVI port, not an HDMI port. There is no loss of signal or quality.
Really, the only difference between DVI and HDMI is the fact that HDMI transmits both video and digital audio. DVI doesn't do this, so you must resort to transmitting audio separately. Not a problem: use an optical digital cable, which your Macbook Pro will accept (as will most HDTVs). That said, you might be better off connecting the audio portion of your MBP's output to a home entertainment (surround sound??) receiver.
Now, I'm not sure about the "progressive scan" capabilities of the Macbook Pro and DVD Player. You'll have to research that yourself. I can tell you that normal DVDs can be "upconverted" by a progressive scan set-top DVD player, and the result looks absolutely stunning on an HDTV. It's not quite as good as full HD, but it comes pretty close. Also, many newer units are being made with HDMI ports. In other words, the DVD is upconverted, and the result is transmitted over a full HD connection. Best of all, these set-top boxes can be had for under $100.
BTW, the composite video you suggest is simply "standard definition," and not the best SD at that (S-Video is better). Component video (where there are three separate "RCA"-type connectors) is much, much better, but even that doesn't match digital (DVI or HDMI). Also, the DVI-to-HDMI cable you will need can be had at Walmart for around $30. They can also be found at places like Best Buy or CompUSA, but these retailers tend to over-charge for over-blown items (No one needs a "Monster" HDMI cable that costs over $100, and which does no more than the $30 cable from Walmart; digital is digital).

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.

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).

Connecting an Xbox using the DVI to Video adapter to a Display

I have a second display (Vision 17'' TFT LCD Display) and I love using it with my Power Book using the DVI out. I also have a PC that shares this display through a VGA input port also on the display. Anyways, I want to use the display for my Xbox which has the three component cables. To do this, I was planning on using the "Apple DVI to Video Adapter" but Is this possible? I know it works if the signal is going out the DVI port to an external display but does it work in reverse? In theory I would have the Yellow video cable going to the adapter and the two audio cables going to a "Y" stereo mini cable into the audio in port on the monitor. Possible? Other ideas? Thanks.
-Daniel

no, it won't work. the adapter does not transcode any video signal, it simply connects the appropriate breakout to the analog lines that are already present on the Mac's DVI output, as per the DVI-* spec. unfortunately, it will not work in reverse.
someone at Microsoft has claimed that the 360 does support HDMI and DVI, but the cable is simply not available yet. I find this comment somewhat suspicious, because the demand IS there already, and there is a HUGE base of people waiting for this.
MS does support VGA output now, so you could use a 2x1 VGA switcher to share the VGA input between the PC and 360. I would also get a KVM that supports audio. there are lots of options out there and they do not cost too much money. Y'ing the input on audio is not a great idea, because depending upon the impedence of the ins/outs, you might get a gain/distortion/bleed issue.

Problem using the DVI to Video adapter

I am using a MacBook Pro. I am using the DVI to Video cable to connect my MBP to the TV. It was working fine and I was watching movies and videos. Suddenly I am having problem and its not working.
I hooked up the DVI to Video adaptor on the PC side . Black and white signal which is blurred/blocked/and modes across the screen. I tried playing with refresh settings, resolutions, etc but nothing is happening
Even in the display I am not able to see the NTSC
settings anymore. When it was working before the display changes automatically once i connect the adapter. But now it refresh but the display is not changing. currenly my display is set to 1440 * 900.
any idea why the display is not working, is it a driver issue.

Have you played with the "Mirror Displays" option in the arrangement tab?

Apple DVI to Video Adapter working but not anymore

Hello,
I have the Apple DVI to Video Adapter connected to standard TV via Rca, This had worked for a couple of months and suddenly the image went blur with some lines, it is hard to see something clear but I see the desktop on my TV. Is there something that I am missing? Configuration? I tested the Rca cable and it's fine..
Many Thanks

On the TV side, I'll assume it works properly from other inputs and that controls on the TV's built-in menu did not get reset somehow.
On the Mac side, video output settings are stored in PRAM, so you could try resetting the PRAM if you haven't done that already.

Does the Thunderbolt to Firewire adapter work on windows?

I'm planning on buying an Asus G55VW-DH71 gaming laptop, which has a thunderbolt port. I would like to be able to control my PreSonus digital audio mixer with it, and unfortunately, it only has a firewire for connecting to it. So, I would want to connect Apple's Thunderbolt to Firewire adapter into the laptop and the mixer's firewire cable.
Does the adapter work on windows 7/8?
Also - getting a macbook is out of the question.

I have pretty much the same need as you and purchased a HP laptop with Thunderbolt port and Windows 8. I also picked up the Apple Thunderbolt to Firewire adapter. I have been unable to get Windows to detect the Firewire side of the adapter. Windows 8 seems to pick up the Thunderbolt controller correctly and shows it as an extension of the PCI express bus.
I have found no set of drivers that I can add that will get the Firewire side to be recognized by Win8. Win 8 should have 1394b drivers native, so I don't know what the problem is. I wish I could get this to work, because I just don't have the option of getting a MacBook for the things I need to do.
Right now the only other Thunderbolt to Firewire option on the horizon seems to be the Belkin Thunderbolt Express Dock, but that has 2 problems.... 1, it is still in pre-order and 2, it is ~$300.

How does the new HTML5 video Support work? and what are the limitations?

So the new Edge has been relased along with many new features including HTML5 video support So along with the new feature here are a few new questions!
How does Edge load the Video? is it fully preloaded before Edge shows the content ? Or is it more of a "youtube" pregressive load while playing?
Or can we choose?
What is the recommended video file size example 4mb ?
How does edge deal with browsers that only support .ogg or .webm instead of mp4?
How is the support on ISO & tablets? load times, "lag" etc?

When you import an audio or video file a group is created for you. You can import media with the same name(videosample.ogv; videosample.mp4) to this group for ensuring browser compatibility. The corresponding format will be chosen depending on the browser that loads the composition.
Regarding WebM format - You can also add a webm file in your composition;However since this is a royalty format, Animate will not show a live preview inside the Authoring tool. If you browser supports this then it will definitely play fine on browser preview.
You can take a look at the In-app Video lesson which is available to you in the lesson panel for more details on how this works.
And yes you have pre-load options for HTML5 Video too, however progressive download is not available. You will need to use scripting using JS for getting this functionality.
Hope this helps and do try this out.

Ok...DVI to Video Adapter will almost never work on MAC PRO, what the....

ok
Thank you apple for making us all by the grand Mac Pro and upgrade to better video cards (like in my case 8800gt) and then offering no solution to replace the DVi to Video adapter which allows to have video mirroring.
Anyone has any idea how to make extended desktop or video mirroring work since this adapter is no longer compatible?
Thank you

Yes I know that. my question is regarding what to use for a 8800 card

DVI to Video Adapter with NVIDIA 8800 GT not working

Hi all. I have the new Mac Pro Octo (mar '08) with the NVIDIA GFORCE 8800 GT card. I cannot find anywhere what may be wrong. Only on the Apple Website for the adapter that the only Mac Pro it works with is the Mac Pro (with ATI X1900 XT). However, both tech support and Apple's Store staff said this would work, prior to buying it. Well, my computer does not recognize the TV monitor hooked up via S-Video. I've powered everything down, restarted, unplugged and replugged in both orders, and switched inputs on the TV and receiver both. Nothing.
Any one know if this does or does not work with this computer???
Thanks.

Never mind. Found this out via Apples own website. Thanks APPLE TECH SUPPORT and STORE STAFF for getting me to buy a useless cable!
Mac Pro Computers (January 2008)
The Mac Pro computers with Quad-Core Intel Xeon 5400 Series microprocessors were introduced in January 2008. The Mac Pro’s graphics subsystem interfaces to the North Bridge via a 16-lane PCIe 2.0 bus. For information on the PCI Express graphics support and expansion, refer to PCI Developer Note.
The following sections describe the Mac Pro’s graphics subsystem.
Graphics Cards
Supported graphics cards have dual-link DVI connectors, supporting 30-inch Apple Cinema HD Displays on both ports.
For information on video memory, power, and features refer to Table 1.
All of the supported graphics cards support dual displays in either extended desktop or video mirroring mode; for more detail, see “External Display Modes.”

The GeForce 8800GT graphics card requires that a booster cable be connected from the PCI slot to the auxiliary power connector. The Quadro FX 5600 graphics card requires two booster cables be connected from the PCI slot to the auxiliary power connector. For additional information, refer to the PCI Developer Note.
The Mac Pro supports the 20-inch Apple Cinema Display at a resolution of 1680 x 1050, the 23-inch Apple Cinema HD Display at a resolution of 1920 x 1200, and the 30-inch Apple Cinema HD Display at a resolution of 2560 x 1600. All ports support a maximum resolution of 2048 x 1536 at 32-bit with 85 Hz refresh rate. Multiple PCI Express graphics cards can support three or more displays.

For information on video ports, see “Video Monitor Ports.” For information on PCI Express expansion slots, refer to PCI Developer Note.
Video Monitor Ports
The Mac Pro has a DVI connector for an external video monitor. For a description of the DVI connector, refer to Figure 4 and Table 30.
The graphics data sent to the digital monitor use transition minimized differential signaling (TMDS). TMDS uses an encoding algorithm to convert bytes of graphics data into characters that are transition-minimized to reduce electromagnetic interference (EMI) with copper cables and DC balanced for transmission over fiber optic cables. The TMDS algorithm also provides robust clock recovery for greater skew tolerance with longer cables or low-cost short cables.
Note: The Mac Pro computer includes a DVI to VGA Adapter.
DVI to Video Adapter
The Radeon HD 2600 XT graphics card supports an optional DVI to S-video/composite adapter that provides S-video and composite output to a PAL or NTSC video monitor or VCR. When a display is connected by way of the video adapter, the computer detects the type of adapter and enables the composite and S-video outputs. The settings for the resolutions and standards (NTSC or PAL) are then selectable in the Display pane in System Preferences.
Note: The DVI to Video Adapter does not come packaged with the Mac Pro computer and must be purchased separately.
The video output connector is a 7-pin S-video connector. Figure 5 shows the arrangement of the pins and Table 31 shows the pin assignments on the composite out and S-video connector.
The Mac Pro computer provides video output at picture sizes and frame rates compatible with the NTSC and PAL standards; the picture sizes are listed in Table 32. Those picture sizes produce under-scanned displays on standard monitors.

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.

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...

Apple DVI to Video Adapter on PC???? WILL IT WORK?

Will the Apple DVI to Video Adapter work on PC's as well as Apple? I own a mac but the computer I need to convert on is an older PC with a DVI port on back. Will it work? It's just an adaptor right? It cn't be built to ONLY work on mac...theres no software in that little thing.
HELP!!! before I buy

No, it won't work with a PC. It requires the video card support the adapter, and since it was made for Apple cards, chances are the PC one won't. You might be lucky, but I doubt it.
