DVI --- S-Video/Composite - Blinking?

I have a DVI to S-Video/Composite adapter that I'm plugging into a video mixer for Keynote presentations, that displays on various resolution monitors (some are regular TVs while others are flat screen LCDs). Seemingly without reason, all the monitors begin blinking until I unplug / plug the connection back in again. From that point on, sometimes my presentation has no issues at all, while other times it seems to immediately start happening again. Has anyone experienced this issue as well?

Apple's video adapters have a ROM chip inside them with EDID data contained within the ROM. That is one thing that will definitely be different between the two. The NTSC and PAL version (M9267G/A) gives priority to NTSC. This could cause problems in a PAL country. If you hooked a PAL TV up using this adapter, you might get a rolling (non-synced) screen and you'd have no good way to recover since the image on the screen would be unusable.
I don't think one adapter would have any advantage over the other in terms of PAL picture quality. It would just be a question of compatibility as outlined above. That's my best guess.

No display after sleep with macmini using DVI - S-video/composite under XP

Hi guys, I have installed XP on my mini. I have CRT TV so I'm using
DVI -> S-video/composite to output to my TV.
The problem is after sleep - there is no display (it's woking only after reset).
I installed the latest drivers from the mac os 10.5 DVD & updated the graphics driver from Intel.
Please help

Unfortunately, no answer, as I'm having the similar problem with a Samsung SyncMaster 215tw and a G4 Mini. It works with the DVI-VGA adapter and the VGA cable into the montor's VGA port. However, connecting with the G$ Mini's DVI port with the monitor's DVI port using a DVI cable doesn't work. I cannot figure out why this doesn't work.
The DVI cable is good and the monitor's DVI port is good, as the connection does work using my friend's Intel Mini's DVI port connected to the monitor's DVI port using the DVI cable.
The monitor is new, too, and otherwise works fine with my other Macs connected with the VGA port. (I've not tried the additional ports as yet.)
Although the monitor is supposed to synchroize automatically, I also tried manually presetting the G4 Mini to different resolutions, but that didn't make any difference. The screen remains black when it should be showing the booting Apple icon.
Any idea what is going wrong here, please, as it sounds as if this same thing occurs with various monitors?

Mini-DVI to Video (composite or S-Video), can't get it to work

hi guys,
I got a MacBook (bought in Japan) and a mini-DVI to Video adapter (Bought in Canada recently).
I am trying to watch TV, but I am getting a very bad b&w image (as if I was watching using a very old antenna).
I changed the display resolution to the lowest option 640x480 (60Mhz) (Actually I tried every single resolution)
I tried both the yellow composite cable or the S-Video to yellow composite cable but both produce the exact same image.
I am out of ideas, I have a feeling that it's trying to send a PAL signal on a NTSC television (Is that even possible?)
Any suggestions are highly appreciated.
Many thanks
ps. I'm running on Leopard
ps2. My TV is not old, it's a pretty decent Toshiba

Here is the content below from the site, tricky to find if your a novice like me!;
Indeed there is.
1.First connect the DVI cable, so the Powerbook switches to multiple display.
2. Launch system preferences>display
3. There should now be 3 tabs on the top (Display, Arrangement,Color). Select the 'Arrangement' tab.
4. Check the 'Mirror Displays' box. The Powerbook display will reset to mirror mode.
5. When the display settles, pull out the dvi cable, let it settle and plug it in again.
6. You should now see two dialogs, Color LCD and NTSC/PAL.
7. Select the resolution you want on the Color LCD dialog.
8. Select to bring to front the NTSC/PAL dialog and you will see the Refresh rate drop down list available for 50 Hertz(PAL) selection.
Looks quite bothersome but works for me. Was trying to record game session on a PAL camcorder and stumbled on your discussion while looking for solutions, found it while meddling the Preferences. Thought I'd share it even though it's been some time. Happy New Year.

Apple Mini-DVI to Video Adapter Question

I want to hook up my macbook (late 2008 model) to my tv. Will the Apple Mini-DVI to Video Adapter
work? If it will work on my tv then what else do I need to get? It looks like you need other wires to hook up to your tv? Thanks in advance for your help!

The new MacBooks that use the NVIDIA 9400M video chip do _not_ support output to analog TVs. Thus, with the current MacBooks the only way to get output to an analog TV is with a third-party VGA-to-analog TV converter box -- you can't just use one of Apple's cables (although you'll need the mini display port to VGA adapter cable to connect to a third-party VGA-to-TV converter box).
More specifically, you can _not_ use one of Apple's $19, DVI to Video (composite/S-Video) adapters on the new MacBooks.

Problem with DVI to video adapter on MBP 2.2 (using FInal Cut Pro)

When I plug an Apple DVI to video (composite and S video) adapter into the DVI socket the screen reduces its resolution and the higher screen resolutions are no longer available from system preferences. This happens on both my MBPros so is this a fault with the adapter or what ...? The reason I'm doing this is to have dual display for Final Cut Pro 7 although this behaviour happens withourt FCP running , which is why I ask in this section.

Setting it to FireWire Basic didn't work. It still only played thru the first few frames, then came back with the same message- that there were dropped frames detected (not bad sectors, as I reported earlier). One other thing I noticed: after the failed capture attempt, it resets the In point to the same time code as the Out point.
I'm going to try capturing by just clicking Play, then clicking the Capture Now button, and see if that works.

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 S-Video & Composite plug cable needed for output to audio/TV system

I'm in need of a DVI to S-Video and Composite plug cable to replace the Monster iTV Link cable I used with my 12" Aluminum PowerBook. (http://www.monstercable.com/apple/Computer.asp) I use it to output to my audio/TV system.
Whereas the PowerBook used a mini-DVI port and had the audio output jack on the same side of the computer, the MacBook Pro uses a full size DVI port and has the audio jack on the opposite side!
I've been unable to find a cable so that I can connect up to a TV. Does anyone know where I can find one? Or perhaps a DVI to mini-DVI adapter? Or perhaps a VGA to S-Video/Composite cable and I can use the DVI to VGA adapter that came with the computer?
This is very frustrating!

GeForce4 MX using DVI to S-VIDEO / Composite Adapter

Hi peoples,
I'm running a PowerMac G4 Dual-867MHz MDD, with nVIDIA GeForce4 MX Video card.
I want to connect this PowerMac to the TV, so I bought the DVI to S-VIDEO/Composite, to find out that it doesn't work with this video card.
My question is;
is there something I can do to get this adapter working with my current set up, or do i need another video card or something?
Any advice would be appreciated.
Cheers.

A new video card would work. e.g.
ATI Radeon Pro PC&Mac Edition 256 MB. Has two DVI
ports. The DVI to S_Video adapter will work on one
port, the other port can handle a screen up to 30".
ATI Radeon 9800 Pro Mac Edition 256 MB. Better 3D
performance. One DVI port (single-link, no 30"
support), VGA port, and S-Video port. S-Video to
composite adapter included.
There are also used Mac, and modified PC cards that
would work.
Thanks for your reply. 3D performance isn't really required, as it's being used a server machine that will be hooked up to the TV, so it's hard to justify a Radeon 9800 Pro. Hopefull I can find something cheap & nasty, else this baby is going on eBay.
Cheers.

Mini Dvi to S-video/Composite/RCA

I have a 2007 black macbook and recently bought a Mini-DVI to video adapter (brand-dynex) and hooked it up to my older television (TV has no hdmi hookup or dvi, just S-Video and RCA) and I could faintly make out my computer screen but it was all "scratchy" and was moving across the screen. I changed the resolution and it became black and gray lines moving up and down the screen. I was wondering how can I hook my computer up to this older TV to watch movies online (I wont be upset with low quality). Do I need to purchase the Apple brand adapter or is there some "tweeking" I can do to make the Dynex one work? thanks

Honestly, I was afraid of this... Oh well, I bought it off ebay and got my money refunded so no harm done. Thanks for the help and if anyone can figure some application or anything and get their adaptor to work, please contact me thanks....

DVI to s-video/ composite Video Adaptors- diff b/w 2 Apple products?

I am trying to get information regarding the difference between 2
Apple display accessories.
- Apple PAL DVI to Video Adaptor -Apple part number MA026ZM/A
- Apple DVI to Video Adaptor -Apple part number M9267G/A
The second is not just an NTSC version of the first, in that it
supports both PAL and NTSC - and apparently the Pin outs are
different for both. I am trying to work out which will give a better
result for PAL video output (interlace timings etc). Kbase articles
just say that M9267G/A supports both NTSC and PAL and that MA026ZM/A
supports PAL. It seems strange that the PAL item exists if the other
adaptor supports PAL also ? Apple Australia say they don't know.
thoughts ? thanks in advance

Apple Mini-DVI to Video Adapter

I have just purhased a new Macbook. My first mac ever
My question is regardng the Apple Mini-DVI to Video Adapter.
Do I read that correctly that I can hook my macbook up via rca and s-video but not composite? Does Apple make one cable that will do both?
I would like the ability to hook up to a projector which will likely be composite. As well RCA/S-video via t.v or DVD inputs.
Thanks
Tig

For VGA you will need the Mini-DVI to VGA adapter. For composite video you will need the Mini-DVI to video adapter. If you want sound while using the video adapter you will need a 3.5mm to rca stereo cable. This is a y cable like this Example of 3.5mm to RCA Y cable
FYI the RCA output on the video adapter is composite video.

Apple Mini-DVI to Video Adapter Questions

I'm in the processing of producing an instructional video using an Intel Core Duo iMac and iMovie. This content will be distributed primarily via broadcast over cable TV. Considering this, I'd like to be able to edit and view my dv footage on a TV monitor as I work.
I was told by the Apple Store person that the Apple Mini-DVI to Video Adapter (http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/6314001/wo/jY18n ncCp3Nx2tYjws52iCaPkH1/1.0.21.1.0.8.25.7.11.2.3) will enable me to
1. Mirror my desktop to simultaneously show me what my iMovie edits will look like on a TV; and
2. Enable me to edit in iMovie using the TV as my desktop.
Am I understanding the capabilities of the Apple Mini-DVI to Video Adapter correctly?
Regarding Cables
1. I currently use an RCA composite cable to view dv footage from my camcorder directly on the TV. Is this the same cable I'd attach to the Mini-DVI to Video Adapter?
2. The DVD recorder/player my TV signal is routed through has an s-video port. Is there a benefit to using an s-video connection in addition to/or instead of the RCA connections?
Thanks for helping me understand this setup scenario!

Ditto to Karsten's post:
"Mirroring" a Mac's output to a TV, or plugging in an adaptor to provide a display on a Mac's screen and simultaneously on a TV ruins the Mac's display while this is happening by lowering its resolution. Ugghhh! (..I've tried this several times, in order to get a 'TV' signal out, showing the Mac's desktop, but it's hopeless..)
Karsten's method is the best - output to camcorder via the normal FireWire cable, and plug a TV or monitor into the camcorder's A/V Out socket!
[..Note, though, that Matti has pointed out that - what was it..? - during editing, some updating of the TV-thro-camcorder display doesn't work correctly. I can't remember exactly what the problem was, and I don't see it mentioned on Matti's Bugs Page, but there was some slight oddity. Nevertheless, this is still the best way of viewing on a TV or monitor..]

Apple Mini-DVI to Video Adapter and Mac mini (2009)

Can anyone tell me whether the Apple Mini-DVI to Video Adapter listed here:
http://store.apple.com/ca/product/M9319G/A
works with the latest Mac mini (early 2009)?
If it does not what other solutions are there to connect to composite, component or s-video?

KC from Ann Arbor, MI had this to say as a review on the page to which you have linked;
10-May-2009
I bought a Mac Mini (May 2009) and this Mini-DVI to Video adapter with plans to use it to send an S-video signal to an analog TV. Though the sales staff at the Apple store said it should work, it does not. The graphics card apparently should support it, and it may be addressed with a future driver update, but as of now this does not work. I have used a mini-DVI to VGA adapter and monitor to verify that the port is working, and also verified that the S-video cable and TV input work. There are third party VGA to S-video/RCA adapters available so I plan to use one of those for my purposes. This is probably a 5-star product when used with the right Mac; however, Apple should have made it clear that having a mini-DVI port on your Mac is necessary but not sufficient for this to work - hence the 3 stars.

Using S-Video w/ the Mini DVI to Video Adapter

I just purchased a MacBook last week and I also purchased a Mini DVI to Video adapter for it so I can use the built-in DVD player to watch movies on my TV. I have a composite to composite cable and that worked fine when I connected the cable between the Mini DVI to Video Adapter and my TV. However, when I tried to use a S-Video cable and connected that between the Mini DVI to Video Adapter and my TV; then I got no picture at all. All I saw on the TV was a picture of the MAC desktop w/o the dock and the movie or nothing else played at all.
Is the composite connection a better connection for the MAC, or, are there some settings I need to work with on the MAC to get the S-Video connection to work?

I managed to figure this one out, by fluke. The MacBook has to be powered on and ready for user input prior to connecting the mini DVI to video adapter with the s video already connected to it, and to the TV. Once I did it this way, it worked fine. I just thought I'd share this.

Mini-DVI to Video Adapter No Longer Compatible

This is an infuriating subject for me. I had a 2007 2.0Ghz Intel Core 2 Duo White Macbook. On a daily basis i used it with my widescreen TV. I am not made of money, so it is an old tube screen that requires a composite connection.
When that macbook decided to not work anymore, even after several repairs, they replaced it with a new 2009 2.0Ghz Intel Core 2 Duo white macbook. Of course, the higher spec that came with this seemed like i should have been grateful. No, I've just been P.O'd ever since. I can no longer use my Macbook to watch movies on my big screen as the DVI adaptor which i paid a completely stupid amount of money for no longer works. I'm sure this problem could be fixed with some kind of a patch for the NVIDIA GeForce 9400M it comes with. But i guess they have just forgot about the white macbook now. Great.
Does anyone out there know of any way around this problem? Again, i want to connect a 2.0GHz Intel Core 2 Duo white MacBook introduced after January 2009 to a composite connection as once used in the Mini-DVI to Video Adaptor. Anyone know of a solution?
I ask again for this to not be deleted like all my other negative posts. It DOES contain a question, which i very much wish to be answered.
Regards,
Steve.

I dont think you understand. Yes, it does use the same connections - it all connects up properly. But after 2009 the white macbooks no longer recognize the TV-Out when you connect the mini-DVI to Video adaptor.
On my old 2007 white intel macbook that had the old graphics card, i was able to connect it all up then go into display preferences and it allowed me to set up the screens as i wanted (ie mirrored, side by side etc). Now, under displays settings, that is no where to be seen.
Its a nothing to do with anyhting being wrong, its just known that Apple discontinued support for it. Even on the apple store website here, you will see in small print under the adapter that it is not supported on white macbooks from 2009 January onwards.
I want to know is there any other solutions.
