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).

  • '09 mini not compatible with mini-DVi to video adapter?

    I hooked up my new '09 mini to my AV receiver via Apple's mini-DVI to video adapter but got no picture. My previous mini ('06 model) worked fine w/ the DVI to video adapter. I'm thinking the mini-DVI port on the new mini doesn't pass analog signals anymore, i.e., it's now DVI-D vs previously being DVI-I.
    Anyone else have this experience w/ the '09 models? I know it works with the older models. I'm just trying to figure out if I have a defective adapter or if the '09 mini's DVI just doesn't pass analog. I noticed the supplied mini-DVI to DVI cable is DVI-D, so maybe that is a hint.

    I doubt that'd work. Usually these adapters work by connecting "legacy" wires on the newer connectors to an older interface. The mac actually produces all the appropriate signals, and the adapter just hooks the wires together appropriately.
    It sounds like the only analog signals the mac is producing are Red-Green-Blue signals, like you'd use for VGA or component video. It's not producing a composite video signal. So if you convert mini-DVI to VGA, the composite line is going to be dead on both.
    The only kind of adapter that could help you would be one with some amount of circuitry that actually pastes the Red-Green-Blue signal into a composite signal. Something like:

  • 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.
    Message was edited by: gonk

    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!

  • 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?

  • Help With Apple DVI to Video Adapter

    I bought a Apple DVI to Video Adapter, which works fine when I connect my computer to my T.V. However, I want to be able to use both my monitor and my T.V. at the same time. If I connect the Apple DVI to Video Adapter to my T.V., then that takes away the port I use to connect my computer monitor. There is another port on the same card, but that size is not compatible with the plug on the of my monitor. Therefore I am limited to using either my T.V., or my computer monitor.
    Is there any device I can get that allows me to connect the computer to the monitor and the T.V. at the same time?
    Thanks

    I thought that cables and adapters worked the same going either direction. I believed that the only concern was the male or female end points on them. Not sure anymore though

  • Inputting audio/video into my macbook pro? with Apple DVI to Video Adapter?

    I work with video, and am trying to save my minidv cam's life. is there a more direct way to input directly from a vcr/television into my macbook pro? because right now i'm having to input from my vcr/television into my minidv then into my macbook through firewire.
    i was considering the Apple DVI to Video Adapter ( http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/wa/RSLID?mco=724 17D66&fnode=home/shopmac/macaccessories/cables&nplm=M9267G/A#overview )
    but i'm fairly certain that this is output-only. does anyone know if there is a way to input through it as well, or anything that works similarly?

  • Using Mac Mini and a 26" Samsung Tube TV with Apple DVI to Video Adapter

    So upon first hooking this adapter up from my Mac Mini to my samsung 27" tube TV, it worked fine–but everything was massive in size. I started changing resolution sizes in the preferences panel and one of them set the screen flickering vertically, like a mismatch in refresh rates.
    Anybody else have this issue and resolve it successfully? It obviously works, it was for me for the first couple minutes, but I can't figure out what sent it flickering–and how to resolve it.
    The TV is connected VIA composite (RCA) cable from the adapter to the video-in port.

    Try starting in Safe mode. That should get your screen back.

  • How to get 16:9 resolutions when using DVI to Video Adapter?

    I just plugged my new Intel Mac Mini into a 16:9 widescreen TV with the Apple DVI to Video Adaptor (PAL Video version).
    It only offers me:
    640x480
    720x480
    720x576
    800x600
    1024x768
    (all interlaced)
    I do get a choice of 50hz (PAL) or 60hz (NTSC).
    However, I don't get the widescreen options I've seen in some Apple screenshots.
    I'm plugging it into a PAL TV via an s-video cable.
    I intend later to plug it into a larger 42" plasma with same cable, but wanted to test it on this TV first.
    More info:
    I noticed, when I bought the "DVI to Video Adapter" that there were NTSC and PAL version. Both seem to do PAL though.
    Any help on this most appreciated.

    Concerning your question, "if only i knew the the correct entries for a custom displayconfig x timing," I think I can answer that one for you.
    It sounds like you have other Macs at your disposal that are correctly driving the TV you are trying to drive with the Intel mini. In that case, install DisplayConfigX on one of those computers and while it is running the TV at the desired resolution, click on the "Card" tab in DCX and then click on the "+" symbol at the bottom right corner. This will open a window in DCX titled "Resolution details" and you will see all the detailed information of the timing you need to enter into DCX on the Intel mini.

  • 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!

    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.

  • 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?

  • DVI to Video Adapter and S-Video Cable = Flipping TV Screen

    S-Video is the better of the two interfaces. Neither is very good when compared with a computer screen, which will have much higher resolution. I doubt you will notice much difference between S-Video and RCA Video but if you have the choice you might as well go S-Video.

  • Need info on DVI to video adapter

    Hi i have a pre-intel mac G5 with one DVI and one ADC port for my monitors. My plan is to buy a DVI splitter and then buy the DVI to video adapter to send one of the split signals to a TV. The apple site says it will work for MacPro, MacBook Pro or Mac Mini and Power Mac G5. Can someone tell me if it will work on my older pre-intel Mac G5? Thanks

    The DVI to video adapter should work on the DVI port of an ATI graphics card, but not on a NVIDIA card. It won't work with a DVI splitter and another monitor. DVI splitters need both outputs to be the same resolution, and are made for digital video signals.
    You could add a PCI card for video

  • Apple DVI to Video adapter + Mini DVI to DVI adapter pins not same

    I just purchased an Apple DVI to Video adaptor so I could plug in a Mac mini to an older tv, however the pin arrangement on the Apple DVI to Video adapter is not the same as the pin arrangement on the Mini DVI to DVI adapter that came with the Mac mini.
    Anyone have any idea what adapter I can use to make this connection?

    James,
    I'm confused here.
    Which Mini do you have?
    I know you posted this in the 2009 Mac Mini section so your Mini should have 2 video out ports.
    1. Mini DVI
    2. Mini DisplayPort
    If that is true, then there is no way you could have connected the DVI to Video adapter in your first post as the new Mini does not have a DVI port.
    The new Mini's come with 1 adapter.
    Mini DVI to DVI adapter.
    I don't know of any Apple adapters that will output to S Video, component or composite connections on the new Mini's.
    The one that osxdude shows above will not work on a new Mini. It say nothing about a Mini in their description:
    *The Mini-DVI to Video adapter is designed for the iMac (Intel Core Duo), MacBook*, and 12-inch PowerBook G4, allowing you to connect to most S-video or Composite enabled devices.*
    Good Luck and let us know what you find.
    Yes, I have a late 2009 Mac mini. It came with the mini DVI to DVI adapter as you stated. I need to hook up to an older tv with yellow component video port. Not knowing any better, and looking online, it looked like the male DVI end of the “Apple DVI to video” adapter would connect to the female DVI end of the “Mini DVI to DVI” adapter that came with the Mac mini. I figured that since they were both DVI plugs, male and female, they would connect, but the “Apple DVI to video” adapter has 4 extra pins, so they won’t.
    Then, following osxdude’s lead, I went to a local independent Apple store, and they told me that the same adapter that osxdude suggested would work, so I bought that (at an inflated price), but as you stated, it does not work. Also, as you stated, the Apple site does not list the Mac mini as being used with this adapter, which is why I did not originally purchase it online. It was only at the insistence of the independent Apple store that it would work that I purchased it. Unfortunately, once the package is opened
    the store were I purchased it will not take it back. Boy... this is getting expensive, and confusing! Why so many adapters?
    After much searching I found this info: http://forums.macrumors.com/showthread.php?t=706736&highlight=monoprice so I’m going to try that.
