ADC to DVI and DVI to VGA on my G5

I have a G5 with an ATI 9600 video card that has both DVI and ADC outputs.  I cannot find am ADC to VGA adapter, but I was wondering if I could use and ADC to DVI adapter and then connect that to a DVI to VGA adapter and use a 2nd VGA monitor on my Mac.  Has anhyone tried this?
Thanks!

ADC to DVI-D adapters pass digital, not analog. There is no way for DVI to VGA to receive analog from the ADC port.

  • 7300GT with DVI and DVI to svideo

    I just wanted to be sure there were no issues when using a DVI connection to an lcd screen and the dvi-to-svideo converter to a television. I don't have a second dvi lcd to test, but the Mac isn't recognizing the dvi-to-svideo connection.

    The X1900 XT actually provides an s-video signal which the adaptor merely picks out. It doesn't actually convert the signal, merely the plug which allows you to use standard s-video cables. The 7300 GT does not provide this extra signal so there is nothing for the adaptor to "pick out".

    You would not be able to get three different displays using the s-video port (this is true on pretty much any graphics card which includes an s-video out connector, even if it is separate from the other connectors). When using the s-video, you have one DVI/VGA connection and the other one is unused. I'm not really sure how, even if the adaptor had worked, this would work. It completely blocks the port. I suppose you COULD split the s-video connection and send the signal to two different devices, but this would only mirror. It would not have two independant displays.
    There is one other option, you could pick up a device such as the following (there may be different types, this is the first I found):
    http://www.aver.com/ppd/averkeyimicro.html
    It actually takes a VGA signal and creates a s-video signal from it. Additionally it looks like it allows passthrough of the original signal to a monitor at the same time (again, only mirroring, not independant). It's just under $100. Also, I came across auctions on eBay (not endorsing them or anything, you assume all risks associated with online bidding, blah, blah) for this device used @ around $30 or so. This SHOULD, according to the description, work. I've never used the device myself.

  • Does Mini Displayport to DVI adapter support analog VGA signal?

    I'm just about to buy a macbook pro. Since the MDP (mini displayport) to DVI and MDP to VGA adapters are £20 a pop, I can only afford to get one. Obviously DVI is better in general, but VGA supports more older hardware, CRTs, and the spare VGA input on one of my displays (where the desktop uses the DVI).
    What I'd like to know is does the MDP to DVI adapter also support the analog VGA signal on certain pins (like most physical desktop DVI ports do)? If it does, since I have about 3 or 4 DVI to VGA adapters lying around, I can get the MDP to DVI adapter and use the DVI to VGA adapters with it if necessary, but if it doesn't I might be better off getting the MDP to VGA...

    No. Unlike DVI, which in the DVI-I configuration has both digital and analog pinouts, DisplayPort (and mini-DisplayPort) are purely digital. Mini-DP to DVI then DVI to VGA will not work. If you look carefully at the Apple Mini-DisplayPort to DVI adapter, you'll notice it's a DVI-D connector - digital pins only.
    The Apple mini-DisplayPort to VGA adapter contains a digital-to-analog converter.
    So, you'll have to choose. If you want VGA, get Apple's mini-DisplayPort to VGA adapter.

  • Can I use the Apple ADC to DVI adapter with a VGA monitor?

    Hey everybody,
    I have a quick question. I work on computers fr friends and family as a hobby. I have an ADC monitor and need ot be able to hook up computers with a VGA port on them to it. Can I use the Apple ADC to DVI adapter along with an Apple DVI to VGA adapter to successfully connect VGA computers to my ADC display? I was assuming this would work and ordered both adapters but now I have made myself nervous about weather or not this will actually work. Has anybody out there successfully done this? Thanks for your help in advance everybody.

    You can't run an ADC display with a VGA computer without a converter. Adapters won't do it.
    a VGA to ADC converter will drive the ADC display directly

    If you have the Apple DVI to ADC adapter
    <http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/wa/RSLID?mco=18 72D402&nplm=M8661LL/B>
    you could use it with a VGA to DVI converter
    <http://www.gefen.com/kvm/product.jsp?prod_id=1310>
    It might be cheaper to get DVI graphics boards for the computers and use the Apple DVI to ADC adapter.

    Your title says "Can I use the Apple ADC to DVI adapter with a VGA monitor?". If you want to connect a VGA monitor to a computer's ADC port you need the ADC to VGA adapter
    <http://www.gefen.com/kvm/product.jsp?prod_id=1299> You can't use an ADC to DVI adapter followed by a DVI to VGA adapter, because the ADC to DVI adapter doesn't pass the analog video signals needed for VGA.

  • Connecting ADC monitor and DVI monitor to G4?

    Hello,
    Like my specs say, I'm running a dual 1 ghz quicksilver 2002 g4 and am trying to connect the 23" display AS WELL as the 15" ADC flatscreen (legacy?)
    My video card is only vga and adc and my computer has an agp slot.
    So I'm figuring that I need a new AGP card with both a DVI and ADC input...correct? If so, does anyone have recommendations on any? How about alternate routes I should take?
    Thank You

    A Mac NVIDIA GeForce4 Ti would work. It has ADC and DVI.

  • Mini-DVI to DVI, DVI to VGA and No video on Samsung SyncMaster LCD

    External monitor works fine on a PC with same adapter (minus the Mini-DVI to DVI). OSX recognizes the external monitor and even gives display options in system preferences, and the mouse moves off the main display into the extended display but external LCD sits in sleep mode, but must detect some sort of video signal because when i pull the cable i get the "No Video Detected" warning on the external monitor. Could OSX be sending a sleep signal to the external display? I checked all the Energy Saver prefs? Any other thoughts?

    Apple's mini-DVI to DVI adapter DOES NOT pass analog VGA signals.
    For some inexplicable reason, Apple chose to use a digital-only DVI-D
    connector. The analog video signals (pins C1 thru C4 in the drawing
    below) are not connected.

    The DDC channel and 'hot plug detect' signals are connected, so

    A DVI to VGA adapter provides a conversion from DVI to VGA.
    A DVI to DVI adapter, what is that? If the input is DVI and the output is DVI, what is the need for an adapter?
    Tell us what you are trying to accomplish.

  • Mini DisplayPort to DVI and VGA - Does it work or not?

    I have just received my new aluminium MacBook Pro, and I think it is awesome. I can even get over the fact that it lacks the full-size DVI connection like the old one has just because it is so nice and shiny. I do need it to work with both DVI and VGA displays though, so I know I will need to buy an adaptor.
    My question is: If I buy either the mini DisplayPort to DVI or the dual-DVI adaptor from the apple store, will either one of them work with a DVI-VGA cable? I have heard so far that the single-DVI adaptor does NOT support the VGA pass-through, but would like some confirmation. Even if it is cheaper to buy both the DVI and VGA adaptors I would prefer the dual-DVI adaptor as long as it can do VGA as well, because one adaptor is better than 2.

    As far as I know daisy chaining adapters will not work for the MiniDisplay port. http://discussions.apple.com/message.jspa?messageID=8300784#8300784
    You will need to buy both adapters, the MiniDisplay to DVI and a MiniDisplay to VGA. I would also suggest you voice your opinion at http://www.apple.com/feedback/macbookpro.html and let them know how you feel about needing to purchase an adapter when one should be included with the computer purchase.

  • I am considering a Apple iMac but would be interested in adding a second monitor. Does it have to be an Apple monitor or can i add any monitor with a thunderbolt cable and DVI or vGA adapter?

    I found that the Thunderbolt input accepts the mini-DVI (in my case converter to VGA for a tutorial use monitor)
    BUT, you have to really oush it in 'til it clicks.  I thought it too loose until I tried it.  works just fine!!

  • Connection to LCD TV - DVI and VGA

    Trying to link my MacBook to my Samsubg LCD TV but it's proving more problematic than I thought. Using a straight DVI-I connection, a decent image appears onscreen although the edges of the screen are cut off uniformly all around. I've tried inputting a custom resolution using DisplayConfigX but that doesn't seem to solve the problem. Whatever resolution I put in there is still the same cut off.
    I've tried using the VGA port on the back of the Samsung using a DVI-VGA converter, but the LCD cannot pick up a signal at all, even though the MacBook recognises the display.
    Any ideas on how I can solve either problem? Many thanks.

    Ok, so I don't know if you are using just a normal converter and connecting it to what port or if you are using the mini-DVI port on the MacBook and connecting an Apple Mini DVI-VGA adapter to it and then having it connect to your TV (or how you did a straight DVI-I connection to the TV)...
    After looking at some of the adapters being sold by Apple on this website, it appears that the Mini DVI-VGA Adapter is a DVI-D type to VGA adapter, which I have no idea what this means for the mini DVI port (do they have D or I types for the mini port?)... But this might affect the use of a straight DVI to DVI cable (I'm assuming you would still need
    an adapter of sorts to get it to plug into the mini port) and these they do have (mini-DVI to DVI adapters that are the DVD-D type).
    Hmm. Also, many people in their reviews were complaining that the adapters were the not common DVI-D version type, and I am guessing this must be that most LCD or Plasma TVs with DVI ports on them are the DVI-I type, while for computer monitors and the DVI ports on most Graphics cards are, from what I saw pre-Christmas while deciding on 2 different Graphics cards with DVI ports and 2 (also) different Widescreen LCD Monitors with DVI ports on them, that most computer related DVI ports are the DVI-D type.
    This in mind, it seems the "D" version type could possibly stand for "Deblocking" and the "I" version type for "Interlaced" (just taking a wild stab in the dark, I have no idea if this is correct) and that the "D" is slightly less quality than the "I" type like maybe comparing a 720p HDTV to a 1080i (or p) HDTV...
    So let me know what cables and port types you are using exactly (or have available) as well as the corresponding Adapters that you might need, and we should be able to get you set up correctly.
    Also, remember that the Display Settings may have to be changed when input is giong to your TV and that there should be the option of using the TV (as second display) as a mirror of your MacBook screen or as an extension of it. With Windows, you could also decide which display you wanted to be your default display (you could choose the TV or monitor as this instead of the MacBook screen) but I don't know if OSX can do this or not as I have never used a Second or Dual Displays with OSX (and only once with Windows).

  • Connecting two Acer monitors with VGA and DVI output to my Macbook Pro (mid 2010)

    Hi All,
    I need to connect 2 Acer monitors that have both VGA and DVI ports to my MacBook Pro.  What's the best way to do that?

    hey! Thats normal for notebook! That actually happens to almost all of us - as there are a small fraction of people with two and more thunderbolt displays or with newest rMBP and external multi-monitor setup.

  • Mixing VGA and DVI monitors with 5770

    Hi everyone,
    I've seen the Apple articles and the forum posts about this, but before I need to check my configuration will work before it has to be used on a show at work (the MP is running screens in a venue). I've seen lots of scenarios with people using all DVI monitors or all VGA, but can't find any examples where they are mixed.
    Here is my proposed setup:
    DVI output - 800 x 600 - First device (DVI input only)
    Mini Display Port 1 - also 800 x 600 - Second device (DVI/VGA input but strongly prefer to use DVI) via Mini Display Port -> DVI adapter (passive?)
    Mini Display Port 2 - 1376 x 7?? - Monitor running the UI (VGA input) via Mini Display Port -> VGA adapter (active?)
    My worry is that there is only one active adapter in the system?
    If this won't work, I have two backup plans, which I would also like to know if it will work or not, please. One of the DVI devices has a buffered DVI link out, so I could use that to feed the other DVI device.
    So Backup plan 1:
    DVI output - 800 x 600 - DVI in of first device
    Mini Display Port 1 - 1376 x 7?? - Monitor running the UI (VGA input) via Mini Display Port -> VGA adapter (active?)
    MDP 2 not used.
    Backup plan 2:
    DVI output - 800 x 600 - DVI in of first device
    Mini Display Port 1 - also 800 x 600 - Second device, VGA input via Mini Display Port -> VGA adapter
    Mini Display Port 2 - 1376 x 7?? - Monitor running the UI (VGA input) via Mini Display Port -> VGA adapter
    Phew, sorry for the essay everyone. Been a long day of trying to research all of this...
    Thanks in advance.

    Obviously backup plan 1 is no problem with only two monitors connected.
    You have a relatively easy set of conditions.  Two of your monitors are single link DVI (resolutions less than 1920 x 1200).  One is vga.  So a mini-displayport (mDP) to VGA counts as one active adapter and all you need is a a mini-displayport to single linke DVI active adapter for one of the others. 
    If you look at AMD Eyefinity Validated Dongles chart you would find that a Accell B087B-006B qualifies as an mini-displayport to single link DVI active adapter. 
    So a possible setup would be:
    DVI --> 800 x 600 DVI display #1
    mDP --> B087B-006B --> 800 x 600 DVI display #2
    mDP --> VGA adapter --> 1376 x 7?? display #3
