Macbook video out problem  mini dvi port????  wierd video tranission

I have been using the Apple cable that converts the mini-dvi to rca jack for connection to external video screen for some time now. All of a sudden, i try to hook it up to the tv to watch a movie and it wont work.
Here is the funny part... it still transmits video, it will show the image of my desktop... today i switched my desktop image, and tried again to hook it up... this time it shows the OLD desktop image... no icons or anything, just the image.
Any ideas as to why its doing this? It worked well last week, no other problems, abuse etc, all of a sudden it doesnt work.
frustrated... please help

Difficult to tell from your description, but it sounds to me like your Displays in System Preferences may be set to extended desktop mode instead of video mirroring mode.

  • White Macbook (Early 2009) Why mini-DVI to S-video adapter no longer works?

    I am a lifelong Mac user and by now think I pretty well know the ins and outs of Macs and most Mac-related issues... but this one has stumped me.
    The new white Macbook was upgraded to include many of the components of its big brother unibody Aluminum Macbooks (including 1066 MHz frontside bus and the NVIDIA 9400M) just over a week ago. I was lucky enough to be in the market for a new laptop about this time and snatched one up a few days ago (retiring my awesome 12" Aluminum PowerBook G4 which is still kicking).
    One of the main reasons I upgraded was to be able to use Silverlight 2.0 (d--- Microsoft) as I can't watch streaming lectures from school without it. A nice bonus would be the ability to stream Netflix videos to my TV through my laptop which I've wanted to do for a while. Anyone who has bought one of these new Macbooks and uses their laptop with their TV as much as I do has probably read one of these two links:
    http://support.apple.com/kb/HT3413
    http://store.apple.com/us/product/M9319G/A?mco=MzE2OTkzMA
    Note the asterisk at the Apple store: "* This adapter is not compatible with the 2.0GHz Intel Core 2 Duo white MacBook introduced in January 2009."
    Can someone tell me why this is? I've been using the s-video out of my Apple laptops for the past 6 years... why change it now? Is this a temporary problem or permanent change?
    I have been fervently searching for a work-around but no blogs, forums, or boards have given me any answers. One tech blogger at http://createdigitalmotion.com/2009/01/22/white-macbook-snubs-adapter-i-want-my- tv-out/ speculates that Apple is cracking down on DRM video being watched on TV's... but that makes no sense, any new TV can use the DVI output still supported by this computer.
    Dear Apple: PLEASE give me my TV back!!! I want to watch Netflix and use that cool Front Row feature you put in your system!

    Thank you for your helpful and detailed response, Ziatron. I am aware Apple is unlikely to peruse my forum post, I was just crying out in anguish at the gods that be, so to speak.
    Everything you wrote is consistent with what I have read in other places, thanks for consolidating it here. I am not as proficient in display technologies as I am in other areas so let me see If I am understanding you correctly. Apple has licensed HDCP technology and is employing it across its desktop and laptop lineups. The new white MacBook was the last of the MacBook lineup to be upgraded to include this new technology and as it still retains the older Mini-DVI out rather than the new Mini-Displayport Apple had to "flip the switch" and turn off the MacBook's ability to put out video through the old adapter. I notice that there is no Mini-Displayport to video adapter available in their store. Am I good so far?
    So I am left to assume that they turned off the capability of outputing to s-video because that output cannot be managed by the new HDCP technology, correct? If so, I suppose I understand but am still frustrated as it seems they are prevent the growth of a few weeds (illegal content) by burning the whole lawn (preventing many such as me from using the output I love). Thanks for your help again.

  • FCP video out from mini-dvi to video adapter

    Is it possible to get the output of viewer / canvas from mini-dvi to video adapter for the external tv out.
    My configurations,
    Final Cut Pro 5.0
    MacBook
    Mac OS X 10.4.8
    Mini-dvi to video adapter for external output of video
    Need to find the solution.
    Please suggest your ideas to get things work.
    Expecting reply soon.

    If you use the Matrix MXO, yes. You can use the DVI out to feed a NTSC/PAL monitor. This is one of the only ways to monitor HDV.
    If you want to monitor DV (either PAL or NTSC), use firewire out to a DV/Analog converter and feed the Monitor from the converter.

  • Mini-DVI to s-video: black bar on left side

    Hi,
    When outputting video through "the mini-DVI to s-video adapter" i have a black bar on the left side of my television.
    It seems like the 1024*768 resolution is not able to completely fit the 4:3 area of my television (the image is to small).
    any ideas?
    thanks!

    I'm absolutely sure everything is displaying and that the image is not deformed in any way.
    So my conclusion is that the image is just smaller (in every dimension) than it should be and than it was before.
    I will try a lower resolution later today.
    thanks for your help and interest!

  • Mini DVI port not working on Macbook

    I often watch movies streaming on the internet by connecting my Macbook to my television via my Mini DVI to S-video adaptor cable.
    Last week, however, it suddenly stopped working. The television can still detect the display, but the image is super distorted and moving in a static-ey way. I can only vaguely make out the icons on my desktop on the TV screen.
    I thought that perhaps my adaptor cable was at fault, so I bought a new one - but the problem remains. I have also tried resetting the PRAM, repairing the disc and permissions with Disc Utility, and cleaning the Mini DVI port. I am pretty certain that it is a hardware problem with the port itself.
    One of the pins on my Mini DVI port looks like it could be out of place. It is kind of squished at the bottom of the port instead of laying flat like the others. I’m thinking that this might be the culprit. However, I have tried to straighten it out using a safety pin and I’m not really able to do it.
    Am I right to assume this is a hardware problem with my port? Any advice about how I might go about fixing this? Is there a way to repair the port without having to replace the whole logic board?
    The Macbook in question is a 2008 Core 2 Duo running Lion.
    Any suggestions at all would be much appreciated!

    Do not dismiss the possibility that the problem may be with the TV.  Based on what you have tried so far, an appointment at an Apple store genius bar is your best option.  The evaluation will be FREE and then you should be in a position to make an informed decision.
    Ciao.

  • Monster iTV Link for Macbook- Mini-DVI ports different...

    I have been watching movies etc. on my TV through my 14" G4 iBook for the last year using the Monster iTV Link with the mini-DVI end. I recently bought a Macbook and expected to do the same with it, but the mini-DVI ports are a different shape!
    I have scoured the internet for some information on different mini-DVI ports but have come up short. Can someone explain why Apple would install a different mini-DVI port on the Macbook? Or not install an S-video?
    Regardless of why they did this, I now need a new adapter or Monster needs to make a new iTV Link cable for Macbook. Has anyone seen an iTV link for Macbook? Is there one out there I can use?
    I am assuming my other option is to buy the mini-DVI to video adapter, use the audio part of the Monster cable I currently have and get a S-Video cable. However before I acquire more cables and adapters...
    Can someone confirm that the the Mini-DVI end of the Mini-DVI to Video adapter is the correct shape (version) for the MacBook.
    THANKS
    Macbook Intel, 14" G4 iBook   Mac OS X (10.4.7)  

    Welcome to Apple Discussions!
    It would appear the Monster guy is confused what cable you got. The iTV cable I bought up on Google has the standard round-din S-Video connector found on 15" and 17" Powerbook G4s of the same generation, but I don't think that is found on the 12" Powerbook. What you need is a DVI to S-Video connector to hook up the iTV cable from all indications.
    This may be what you are looking for:

  • Mini DVI to S-video display problem

    I connect my macbook to a plasma TV using mini DVI to S-video adapter so I can give keynote presentations. All of a sudden, having not changed any settings, the plasma display went to black & white while my macbook's display remains in color. I have checked with two different s-video cables and with another TV, as well as trying to change the color display in my system preferences, but after several hours have given up. Anyone else have this problem or have any thoughts on how to alleviate it? Thanks
    Hungus

    A wire may have broken inside the mini DVI to S-video adapter. S-video uses one wire for the brightness, and one for the color information. If the color wire breaks you will get a black and white picture. Until Apple replaces the adapter, you could use the composite video output, but the picture will not be as sharp.

  • Combined audio & video from iMac mini DVI & headphone ports to HDMI to TV

    I presently have my iMac connected to my Sony Bravia tv so that the video goes from the mini DVI port through a converter to HDMI to a 25 foot cable, a HDMI coupler and another 25 foot cable to the TV. The video quality is good since I use 24 AWG cables. The audio goes from the headphone port through a 50 foot 3.5 mm cable to a converter to RCA stereo cables to the tv. The audio quality is not very good with this setup and I would like to send the audio over the HDMI cable with the video so that I would have only a single cable over the 50 foot run and could use a HDMI wall plate for a neater installation. I am wondering whether anyone has tried this somewhat expensive solution to my kind of problem, and whether it worked. Atlona DVI + Digital Audio to HDMI Converter. Model: AT-DVID-HDMI

    Not sure if it would work. The audio input is described as +audio (SPDIF) input+ which is not analog or the Toslink optical digital. SPDIF is a digital format, so you would need another converter. And since the video input is full DVI, you'd need a different adapter for the iMac's video output.
    Considering the complexity, additional adapters, rather long travel length, and $199 price for the Atlona device, depending on what you want to show on the HDTV, you may want to consider an Apple TV. The older 40GB version is $149 at the Apple +Special Deals+ page. You can then stream your content wirelessly, and not have to worry about any cabling. But obviously, an Apple TV does not stream everything that that iMac can play, so it would only work if what you want to show is stuff you can play in iTunes. Plus you may want to see what Apple introduces at the 1/27 special event.
    The iMac's audio output port doubles as an optical digital port, with a Toslink adapter, so if the Sony Bravia has optical digital input, you may be able to run a Toslink cable. I believe 50 feet is too long, so you would need some type repeater at the midway point.

  • Video source to firewire and mini DVI ports simultaneously

    Hi
    Can anyone tell me if the MacBook Pro will take simultaneous video feeds through the firewire and mini DVI ports. I want to do live video mixing using USTREAM or BoinxTV.
    thanks

    http://kineme.net/forum/Discussion/DevelopingCompositions/FloggingdeadhorseStere oAnaglyph has some relevant snippets, I think, hotmagicpickle.
    Not sure how relevant this is , but I decided to experiment and can certainly simultaneously view digital video coming in from my FW camcorder and my USB Elgato DDT TV, so you could certainly "get the stuff in there" at the same time using a mixture of FW and USB. Never tried to mix them, though!

  • Problems with Mini DVI to S-Video/RCA adapter

    Hello
    I've got a mac mini and I want to pass its image to a television (note: this television doesn't have HDMI)
    I've bought the Mini DVI to S-Video/RCA adapter, but when I connect it to my TV nothing appers (except some gray lines, which means the signal is reaching the TV, but no image)
    Thanks

    That connector may not be compatible with an Intel Core 2 Duo Mac Mini like yours.

  • New Macbook Pro, no mini-DVI port? (HDTV connect question)

    Most online resources suggest that Mac users can connect their computers to their HDTV's through the mini-DVI port, but I examined my Macbook and saw that the new version (purchased 2 months ago, roughly) doesn't have this port. This being the case, what can I use to connect my laptop to an HDMI cable? Thanks in advance for any and all help!

    MacBook Pros now have a "Thunderbolt" port that is supposed to be backwards compatible with Mini DisplayPort (not Mini-DVI they've used the Mini DisplayPort since 2008) and, likewise, supports an external display at 2560x1600 and passes an audio signal.

    Having problems connecting iMac(late 2006) running 10.7.5 to a Samsung Flat Screen TV using separate audio/speaker cable and HDMI standard cable, mini-DVI to HDMI video converter.  TV displays generic Apple galaxy background and "some" windows (e.g. screen resolution choices).   It does not show Mail or Safari menus.  System preferences'  display "gathered" the Samsung and chose its resolution.  I did not find a way to select the Samsung as my display.
    In addition to having old hardware, we have Verizon FIOS providing internet and TV access.  Is there any way to make this work for us?  We would like to stream video (Netflix) and view shows from the Web.  Do we need Apple TV to do this?  Or is it not possible with our old iMac?  My husband thinks that our Airport could be a factor. 
    Thank you

    Lately, I have been seeing a lot of posts with users trying to use their Macs/iMacs to mirror their streaming video from their Macs to an HDTV.
    There are, actually, many alternatives to choose from than just from a Mac.
    You need to have or invest in a WiFi capable router for all of these examples.
    Apple TV only integrates with WiFi and newer Mac hardware. So, if you want to have total integrated experience, if you have a 2011 Mac or newer, you might as well pay the $100 for the AppleTV box.
    If you have a older Mac, like I have noticed many users do, then you have other options.
    If you want to elimate long cable clutter and having your Mac at the mercy of your TV all of the time,  you can still use the AppleTV box independently or purchase cheaper alternative media streaming boxes from Roku, Sony, Boxee or any number of electronics manufacturers that now have media streaming boxes and media streaming capability built into DVD/Blu-ray players.
    These eliminate long cable clutter by being close to the HDTV where shorter, less expensive cables can be used.
    Another alternative for iPad users is to use an iPad with the USB/HDMI video adapter and use your iPad as the streaming box. This ties up your iPad in much the same way as it does with your Mac, but again the iPad can be close to the TV and use minimal cables to the TV.
    Another alternative to is to use a combination of an iPad and your Mac to stream content that is only available to stream online from a computer. In this case, you can use a desktop remote app on your iPad and Mac. A good and cheap Desktop Remote app is Splashtop Remote. This allows you to completely connect your iPad remotely, over Wifi, to your iMac desktop. The app streams both video and sound to the iPad which is still connected to your HDTV. The resultant stream video picture will be smaller than the size of your HDTV, but it will still be plenty large enough to watch. Again, if you own a iPad and an Intel Mac, this method also allows minimal cabling to the TV.

  • Possible to use old macbook (mini dvi port) with 24 in LED display?

    Is there a combo of adaptors that will allow me to use my older macbook (mini-DVI port) with the new apple LED screens- i.e. adaptors allowing mini-DVI to mini displayport connector that comes with monitor?

    You need this component and a mini DVI to DVI adapter.

    I think you may be right, it's a hardware related MiniDisplay port connector problem.
    I think you can't fix it up by replace MiniDispaly port connector, however fix it by replace whole logic board.
