Mini dvi adapter and long cables. Weak signal?

Hi. I'm having a big problem with my Macbook and a projector (a cinema theatre projector to be more accurate). The projector stays 10m away from the computer. The screen flickers all the time, and colors doesn't appear right. I already spent so much money on this. So this is my setup:
Macbook (i3, 2013) > mini-dvi to hdmi adapter (not from Apple) > 10 meters hdmi cable > hdmi to dvi-d adaptor.
What I've tried so far:
3 other mini-dvi adapters. None of them are from Apple (I know, that may be the problem). DIDNT WORK
Shorter cables. It got better. No more flickering. But still a lot of color distortion. DIDNT WORK
Windows computer. Was still flickering. DIDNT WORK
Windows computer with a smaller cable. WORKED
Different longer cables. All of them gave me the same flickering. DIDNT WORK
TV (instead of a projector) with a small cable and the same adapter: WORKED
BLURAY + long cable + TV: WORKED
Different hdmi to dvi adapter: DIDNT WORK
I'm really stressed out with all of these. The last theory I have is that the non original mini-dvi adaptor has not enough signal for a long hdmi cable. Anyone knows anything about it?

Update:
The same macbook, the same adapters and the same 10m cable connected on a TV. WORKED!
Now this is really strange. Is there any chance that the cinema projector will need more signal strength than a normal TV would?

  • Mini DVI-Adapter Not Working

    Today I went to the Apple Store and got myself one of those fancy new Mini-DVI to DVI adapters, hoping it would work with my screen at home, which I had previously running on the Mini Displayport to VGA Adapter on my original MacBook.
    Strangely, when I plugged the cable into the adapter, and into my computer, nothing happened. I did not get video on the screen, nor did my MacBook detect it. I have tried re-plugging the Mini-DVI adapter and clicking Detect Displays in the Displays Preferences multiple times, but no luck.
    I have seen the screen work with DVI about a year ago, but that was on one of the original MacBook Pros. Am I better off returning this DVI adapter and instead buying a Mini-DVI to VGA Adapter?
    Thanks for any help in resolving this problem.

    I have a 22 inch ViewSonic that I got from a friend about a year ago. I did indeed plug the monitor directly into the adapter.
    I brought my computer, adapter and cable all into the Apple Store, and they said it was all OK, but did replace my DVI adapter thinking it was probably defective. I got home, tested it on my monitor, but still not working. I tested it on a newer HP monitor that's on the family computer, and oddly it worked there.
    A bit of research revealed that the adapter did not send Analog signals on DVI anymore, which confuses me, since the MacBook actually does have Analog signals on that port. I brought my DVI adapter in original packaging in to the Apple store again, and they replaced it with a VGA adapter for free, and sure enough, that solved the problem for me.
    Lesson Learned - don't use DVI with older monitors, stay with VGA.

  • What kind of picture quality can I expect from a Mini DVI adapter to Scart?

    I currently have my iMac connected to my tv via the Apple Mini DVI adapter and a composite video cable. There are two problems with this, one is the poor picture quality in general, the other is that the tv screen is not filled by the image from the iMac, i.e. there are black spaces on the left and the right of the screen.
    So my question is, if I used S-Video to Scart, would it kill the problem with the black borders when viewing Front Row etc..? Also, would there be a significant increase in general picture quality?

    Yes, if you can get an s-video cable and plug that into the SCART adapter, that would be better than plugging in composite video.
    Clearly, having an SCART connection is not going to "improve" the video going in, you're going to be limited by the lowest quality connection. An s-video connection will provide a higher (but probably not a lot) quality signal than composite video.

    You really need a newer Mac Mini with a true HDMI output, because that Mac Mini's DVI output does not support Audio.
    You might try a 3.5mm to RCA adapter
    from the Mac Mini's headphone jack to the TV's audio input,
    but that would require being able to select the Audio input in the TVs menu while using it's HDMI input.
    Optionally you could also use an external 2.1 Speaker System or patch the audio from the Mac Mini to your home stereo system to enhance that older Mac Mini's audio.

    My macbook can work well with mini-dvi adapter to tv out under mac os,but it can't work under windows os..
    If anyone's using their Macbook and has any comments please let me know..
    Thanks.

  • Help! Problem using Mini-DVI adapter

    I'm a teacher, and I need some help.
    I've been using a Mitsubishi XD 250 data projector at school. The setup I have is exactly the same as it was last year, but something strange is happening.
    The data projector uses VGA, so I have the VGA-to-Mini-DVI adapter from Apple.
    I turned on the projector this morning, as I have a presentation for one of my classes today, but it's not working! The projector comes on, and the iMac shows that it recognizes the external display, but the projector says "No Signal." I have no idea what the problem is, as I've tried restarting both the iMac and the projector as well as connecting and disconnecting the cables.
    Any suggestions? I suppose it's possible that something happened to the VGA cable over the summer, but is that likely considering that the iMac recognizes the external display?
    I really need to give this presentation today, so any help would be greatly appreciated!

    Dett;
    It is probably simply the wrong signal source being set on your projector. This is normally a remote control switch or your projector. I don't know this model but they all have multiple input choices. Change the input until you see your Mac.
    Hope this helps

  • Mini dvi adapter

    will the cords i bought a while back for my ipod to play photos on a tv(http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/wa/RSLID?mco=7CB C356E&nplm=M9765G%2FB) work with this?:
    http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/wa/RSLID?mco=6C0 4E07A&nplm=M9319G%2FA
    Thanks.

    I assume you want to send the video from your mac book to some kind of external display.
    in that case then no the cables you have will not work since they have a mini jack at one end.
    The mini dvi adapter is for sending video out of your mac book to a tv /projector or display through an S video cable (audio and video) or an RCA cable (video only). If using the mini dvi with rca you could plug your current cable into your headphone out jack and use the red and white part of it to send audio to a tv or external speaker.

  • Airpot not connecting when mini dvi adapter is pluged in.

    Airport will not work when I hook up a display through the apple mini dvi adapter. When the adapter is unpluged I can connect to the internet. Does anyone know how to fix the problem. Thanks.

    Typically that is an indication the wireless connection is on the edge of reception and the added EMI from the display throws the connection off. What you want to experiment with is placement and proximity of devices. Move the wireless access point closer if possible. Move the display further away from the Mac if possible. Think about line of sight between the wireless access point and the Mac. Is the monitor sitting right in the middle between the two?
    You can also try changing channels that the wireless is working on. Sometimes that's enough.

  • Mini-DVI doesn't fit current mini-DVI adapter??

    I'm trying to do something relatively simple - connect a second flat panel display to my iMac. The problem is, the mini-DVI adapter being sold by Apple right now is a male plug, and my socket is also male. Argh!
    Is there a female/female adapter that will solve this problem for me? Help!

    Hello and Welcome to Apple Discussions, 
    The current Intel iMacs have a MiniDVI port which can use one of the following three adaptors:
    Mini DVI - DVI
    Mini DVI - VGA
    Mini DVI - Composite/S-Video.
    However, the iMac G4 uses the Mini VGA port and can use these two different adaptors:
    Mini VGA - VGA
    Mini VGA - Composite/S-Video (1.0/1.25GHz only).
    The iMac G4 can output Video or VGA but will only support display-mirroring (there is a firmware hack available to enable dual-display support on some iMac G4s but it is not 100% safe.)
    I think you've been sold the wrong adaptor.

  • Conecting Mini DVI to HDMI Video Cable with my mac book pro

    Hi. I just bought Mini DVI to HDMI Video Cable to connect my mac book pro to my HD TV. I connected the cables and put my TV on HDMI input. On the TV it appears the Snow Leopard Background but I can't see my desktop or the icons. What should I do to view my mac book pro on the Tv? Thanks!

    Hi y3p3v3,
    On the TV it appears the Snow Leopard Background but I can't see my desktop or the icons. What should I do to view my mac book pro on the Tv? Thanks!
    You've got it connected, and you're viewing it already! Connect it up again, and try dragging a window either to the left, or right, off your built-in screen. You'll find that it appears on your TV!
    What you're doing is running the computer in "extended desktop" mode. That means that your TV screen is available to put things on, but won't show your menu bar, dock, or icons. Those remain on the "primary screen" which remains your MBP's built-in display.
    When the TV is plugged in, go to System Preferences --> Displays
    The main System Preferences window will remain on your MBP's screen, but a second one should appear on the TV as well. If you go to the one on your MBP's screen, and click the "Arrangement" tab, you'll see two screens shown in the diagram. One will have a menubar. That's your MBPs screen. You can drag the menubar to the other screen to change the primary screen to the TV.
    OR, you can just click "Mirror Displays" and your TV will show the exact same picture as your MBP display. This option is the simplest and will accomplish what you want, I think.
    If you have any other questions, or if you need any clarification, feel free to ask!

  • Is the Mini-Dvi adapter suppose to click into the back on the Mac mini?

    Is the Mini-Dvi adapter suppose to click into the back on the Mac mini? It does on my mac book but not on the Mac mini. I sort of have to just jam it in there, no nice clicking sound, and it does not feel very secure.

    If after 'jamming it in there' it actually works, then at least you know it's the correct type of adapter. However, if it doesn't work, you are definitely not inserting it correctly or into the correct location. In either case, you may have a damaged port - all the connections on the rear when applied correctly with anything like a decent quality standard type connector should work smoothly. You should never have to 'jam' anything into the back of your mini.

  • How do I get a Mini DisplayPort adapter and HDMI connection working for my Older MacBook Pro?

    I bought a Belkin Mini DisplayPort adapter and attempted to hook it up on two different tvs using two different HDMI cords. I've always received a "no signal" message. I haven't even been able to get my desktop to appear. My display settings doesn't include a mirroring option and I only have the option to use my computer as a sound output. I've called apple support and I went to geek squad. Is it just impossible for older MacBooks?? I have Snow Leopard 10.6.8 and all of the forums I've read say that video should work at least. I switched out my adapter for a rocket fish one and still no luck. The geek squad employee couldn't get it to work on either adapters. Please Help!

    I upgraded my OS to Mountain Lion and now it works perfectly. However, I'm getting random green and black splotches on my screen when I'm not using it with the TV.

  • HI, I am trying to connect my macbook pro,  18 months old, to a projector using the mini display port and a cable/connector to a VGA port on the back of the projector.  It all fits but the there is nothing happening? no mirroring option. Any ideas?

    to get to the Detect Displays button you have to hold down the Option key and the button appears.

  • Mac mini display is flicking via HDMI to DVI adapter and DVI cable

    i have received mac mini server (mid 2011) recently. mac mini is connecting the display via HDMI port using DVI cable with a HDMI to DVI adapter.
    the display shows constant flicking. white dots/lines show randomly. it is like those signal noise when watching analog TV.
    the same display works fine and well with macbook pro (early 2008) via DVI port.
    please help. please advise.

    So you know the display is working.
    It seems to me you have a few possible problems.
    1 HDMI-DVI cable is bad
    2 DVI-cable is bad
    3 Connections between cables or computer or monitor are bad.
    4 HDMI port on the computer is bad.
    I assume you've tried #3, and re-connected cables and wiggled inputs.  So then try replacing 1 and then replacing 2 which are cheaper fixes than replacing/fixing 4.........
    FYI, I'm connect my mac mini using the same setup you describe, with no issues....also inspect the cable ends carefully to look for any problems.
