Problem w/mini-display to DV I adapter, a Macbook Pro 13" & 30" Cinema Disp

I recently switched out my old 15" MacBook Pro for a new 13" version. My old MBPro had a DVI input and the connection between that machine and my 30" Studio Display was not a problem.
However, as I now have the 13" and need to use the mini-display adapter I am getting occasional screen flicker and worse, total static on the screen. It's like I'm in the 1950 watching a B&W TV with rabbit ears.
I have checked and rechecked all of the connectors, but this has become a daily battle to get a clear picture.
I know the display has some years on it, but it's been good till now and I'd like to hold on to it.

Make sure you have the latest version of the Mini DisplayPort to Dual-Link DVI adapter. Check via System Profiler (Utilities folder). It should be at least 1.0.2

It could also be a problem with USB power for the adapter. If you have a charger for iPhones or iPods that use USB, try using it to power the adapter (plug the display's USB cable into the computer).

  • Can i connect thunderbolt duo hard drive to the mini display port of a late 2008 macbook pro which do not have thunderbolt port, but have mini display port.

    hi, i have a late 2008 15 inch macbook pro, which have a mini display port.
    I noticed that thunderbolt and mini display port looks a like. So, my question is :
    can i connect thunderbolt duo hard drive to the mini display port of a late 2008 macbook pro which do not have thunderbolt port, but have mini display port.
    thank you

    ken94538,
    no, you’d need a Thunderbolt-to-FireWire adapter or Thunderbolt-to-USB adapter to be able to access your Thunderbolt hard drive from your 2008 MacBook Pro.

  • Problems with Mini Display port to VGA Adapter (A1307)

    This has never worked, at the moment of truth, when we plug in, in front of client. SOmetimes their tech guys fiddle with display settings etc, but to no joy. So, a) should it just work straight way with no changes to settings etc and b) how do I know it is even properly functioning? Is there any troubleshooting I can do at home (without a projector!), or a sequence of things I need to do when I plug in to projector? Any help is gratefully received! Or do i just throw myself on the mercy of the guys at the apple store? Thanks

  • Mini Display Port to VGA adapter with Mac Pro

    Just as a word of advice if you're thinking of buying a new Mac Pro and planning on hooking it up to dual VGA displays at their native resolutions - don't.
    Apple claim it will support 3 VGA displays. That might be true in a very loose sense but not in the sense that you'll actually be able to work with it.
    My experience (all using same adapter, cables and monitors):
    *Mac Pro - Dual screen set up*
    1 x LG Flatron W2242S connected via DVI > VGA adapter - offers native resolution (1680x1050)
    1 x LG Flatron W2242S connected via Mini Display > VGA adapter - does not offer native resolution
    *Mac Pro - Dual* screen set up*
    1 x Iiyama E2472HD connected via DVI - offers native resolution (1920x1080)
    1 x Iiyama E2472HD connected via Mini Display > VGA adapter - offers native resolution (1920x1080) but displays it pillar boxed (i.e. squashed)
    *MacBook Pro - Dual screen set up*
    1 x laptop screen - fine (obviously)
    1 x LG Flatron W2242S connected via Mini Display > VGA adapter - offers native res (1680x1050)
    The conclusions being that despite having the exact same configuration in terms of adapters and monitors my £3k Mac Pro is incapable of doing what my MacBook Pro can.
    I have spoken to Apple about this and they have admitted it is a limitation and suggested buying DVI monitors along with the Dual Link DVI adapter (£70).
    Not ideal.

    DVI-I provides the direct Analog signals needed to get VGA using a very simple adapter.
    DsiplayPort (and its Mini variant) requires a converter to produce VGA or Dual-Link DVI, and the converter must be active/powered. There is a lot of logic in those converters. It may also have additional limitations.
    In general, you should hook your highest resolution, most demanding display up with the DVI to VGA adapter.If running two Mini DisplayPort displays, ALL MiniDisplayPort converters must be active/powered.

  • Can I capture video through a mini display port on a Mid 2012 MacBook Pro?

    I want to run my xbox through a mini displayport adapter into my Mid 2012 MacBook pro to record gameplay. I understand that at one point the 27" iMac's supoorted this feature to an extent. I'm open to other options for inputs, ie: composite cables from the xbox or even VGA. I own a capture card already I'm just interested to see if there is a way around using it to save space and the mess of extra cables.

  • Why does my mini display port to hdmi adapter cut out intermittently?

    I have a MacBook Air 2012. Using a bestbuy mini display port to hdmi adapter connecting to a sony led tv.  The picture and sound transmits to the tv, but the signal would cut out after 10-15 seconds and it would last about 3-5 seconds and then the picture would come back again. 

    to me something happened similar to me but after removing the connector and put it back was solved, and now to use it with my TV I have to make sure both are well connected to both the Mac and plug the HDMI cable and adapter tv .
    I hope that solves your problems resolved as mine
    Blessings.
    a me me a pasado algo similar pero luego de sacar el conector y volverlo a poner se soluciono, y ahora para poder usarlo con mi TV tengo que asegurarme que esten bien conectados ambos tanto el conector al mac como el cable hdmi al tv y al adaptador.
    espero que eso resuelva tus problemas como resolvio los mios
    Bendiciones.

  • Mini Display Port to VGA adapter + Monitor Eizo s2231W = CRASH

    I purchased a new macbook pro last month with 2 adapters, one for VGA the other for DVI. I'm having some trouble with the Mini-DVI to VGA adapter. The Mini Display Port to DVI adapter works well.
    When I attach the VGA adapter to the monitor it works well for a couple of minutes, then I dont know why my MBP crashes and I can see a purple or white screen. The crash is really a crash... cauz I cant do anything. My mac is frozen and the only way to resuscitate him is to keep pressed the power button for a while till it turns off, and then turn it on again.
    You can say... why do you need the VGA if the DVI works...
    the problem is that I'm probably supposed to use it one day attached to a projector because of a presentation at university.
    So I dont wanna see my new macbook pro freezing in front of my professor.
    please help.
    EDIT:
    adding some precious information
    My hardware configuration as regard the graphic chipset is
    NVIDIA GeForce 320M
    The resolution of the external monitor is 1620x1080
    I'M NOT using the mirroring ( but the desktop extension)

    I had the exact same problem. It actually escalated from there and it would crash at the startup screen (the white one with the apple and the spinning gear). The only way I was able to fix this was to reformat the entire computer. I was lucky enough to have backed up all my data when it first started crashing. I've only reformatted yesterday and things seem fine for now. I don't know what caused it, or how to fix the problem any other way.

  • Mini display port to HDMI adapter not working

    I can not get my MacBook OS X to dispaly on my new Samsung LED TV. I have a mini display port to HDMI adapter (two years old) conneted with an HDMI cable (new) into the HDMI input on the TV. I tried both inputs, tried resetting the TV, plugging, unplugging, restarting, checked all my system preferences...I can not figure it out. I took my cables to a local store, tested the HDMI cable, and it works. Tested the adapter and they had the same problem I have on my Mac. The screen will flash blue when you plug it in, but will not show up in the TV. I think the adapter must be bad, nothing else makes sense???

    Hi Kater24,
    Apple doesn't make a Mini DisplayPort to HDMI adapter, so the one you've got there is a 3rd party one that's designed to work with the Mini DisplayPort on your Apple computer. The adapter is pretty much plug-n-play, there's no configuration necessary. Plug it into the machine, the HDMI cable from the other end of the adapter into your TV, select the HDMI input on your TV and fire up the computer.
    If that's not working it's possibly an issue with the adapter and/or cable to the TV. Any chance you might have access to another TV for troubleshooting purposes?

  • I have a Samsung HD TV and I purchased a Mini Display port to HDMI Adapter today. For some strange reason I get no display on my HD tv. I even tried switching a few HDMI cables and nothing popped up. I made sure my computer was updated. Help pls

    I have a Samsung HD TV and I purchased a Mini Display port to HDMI Adapter today. For some strange reason I get no display on my HD tv. I even tried switching a few HDMI cables and nothing popped up. I made sure my computer performed all software updates, and I even tried calling Apple Support. They just told me to keep trying different hdmi cables and see if anything pops up. Does anybody know what the problem is? My HDMI cable is from "rocketfish" also my display port is too.

    You may have the screen refresh rate set higher than the TV is generally able to track reliably. It may be able to get there most times, but occasionally loses sync because it is out of its nominal range.
    I suggest you sit down with the manual for the TV and find out what resolutions at what refresh rates it intends to support through VGA, and make sure your screen settings are near (or below) those limits.

    No. You need a converter box like this to go with your MDP-VGA adapter:

  • Im having trouble connecting my macbookpro to the tv. im using a mini display port to hdmi adapter, when i switch tv/video to hdmi on the tv nothing pops up, and i dont have the arrangement tap on the display settings, please help!

    im having trouble connecting my macbookpro to the tv. im using a mini display port to hdmi adapter, when i switch tv/video to hdmi on the tv nothing pops up, and i dont have the arrangement tap on the display settings, please help!

    I've found that the order of operations, so-to-speak, can be important when hooking up mini display port to HDMI.  I have the most success with the following operations in this order:
    1)  Plug HDMI cable into mini displayport adapter (the cable should not be plugged into either the TV or the computer at this point)
    2)  Plug the mini displayport end of your new super-cable to the computer.
    3)  Plug the HDMI end into your TV.
    4)  Switch inputs on your TV to the proper input.
    5)  If still nothing on the TV, try a different HDMI port on your TV.
    Hopefully this helps!  Good luck.

    The resolution available with the Apple Mini DisplayPort to VGA Adapter is 1920 x 1200. VGA displays that use higher refresh rates (such as 85 Hz) at resolutions of 1600 x 1200 or greater may not generate video properly until you lower the refresh rate.

    How can I detect displays?
    If the detect displays option is not available, hold down the Option key while you are in the Display pane.
    How do I select additional resolutions on my display?
    You can use the Display pane of System Preferences to specify how your display works. Not all options appear for all display models. By default the best resolution for your display will already be selected in System Preferences.
    To select a different resolution, use the Scaled option. Some additional resolutions may be available when you hold the Option button.
    I hope this information helps ....
