Macbook receiving AM radio via display port connector'

A few weeks ago, I discovered that when my Mini Displayport to VGA connector was plugged in, I heard a buzz through my speakers. It didnt bother me that much, so I just dealt with it. However, today I was plugging my external speakers in, and when the connector was about half way in.. I started to hear audio that I knew wasnt on my computer. Turns out it was commentary on a college basketball game. I started to listen some more, and discovered that it was 1530am. Seeing as I use just a standard set of 5.1 computer speakers... I found this to be extremely odd, so I figured id share this with everyone. Any ideas why this may happen?

Problems like that can be tricky to track down and eliminate but this type of device often provides a solution without ever finding out for sure the root of the problem:

Depending on what type of connections are on the speakers you own, you may need to purchase one or more simple cable converters that go from the RCA-type plug interface of the linked device to a normal, 3.5 mm stereo mini-point connection.
Another thing that might work would be a simple choke appled to the audio cable between the Mac and the speakers:

  • Mini-DVI to mini-Display port connector?

    Is Apple releasing a cable that connects mini-dvi to mini-display port?
    My company today told me that I will get a new Macbook Pro with a mini-display port built in, but I ordered a cinema display directly from Apple.
    I plan to connect the new Macbook Pro to the new cinema display (so I can watch all my TV shows in GLORIOUS HD AND IN C.O.L.O.U.R) but I also want to connect my old black Macbook, and my Mac Pro to the new cinema display. (so other members in my family can use the display on their own macbooks when I'm not using it)
    This cable will REALLY help, otherwise, I feel like I just bought a new display for myself.

    Apple just today has announced free licensing of their MDP technology so that third party companies can incorporate it themselves as well as build things like adapters. I have been saying since this whole controversy started, that Apple would never change their entire product line to MDP and effectively orphan an entire legacy group from upgrading with Apple products, especially in this economy. So before this thread ets ugly, read the article from Ars Technica:

    18. What is the maximum resolution available for use with the Apple Mini DisplayPort to VGA adapter?
    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 ....

  • Will an X220 drive a Dell UP2414Q 4K 3840 x 2160 Monitor via Display Port?

    I've not been able to find any information about this on the web and there is definitely some confusion about DisplayPort versions - could some one answer the question will an X220 drive a Dell UP2414Q 4K IPS Monitor at it's native resolution of 3840 x 2160 Monitor via Display Port? Would that be at 30Hz rather than 60Hz?
    Many thanks, Mark.
    Solved!
    Go to Solution.

    The X220 will drive the Dell UP2414Q 4K resolution through Displayport. I have tested this on the Pro2840m LCD which has the same resolution. But only on 30 hz refresh rate.
    The X220 with the Series 3 Workstation Dock will drive 2 of the Pro2840m through 2 separate displayport.
    The X201 will also drive this 4K resolution, as long as the LCD's 4K can accept Displayport 1.1 standard (on the 1.2 standard, the LCD will stay blank).
    https://www.flickr.com/photos/lead_org/14671257827/in/set-72157645860787090
    the above image confirms the 4K resolution and my X220 driving that resolution @ 30 hz.
    For 60 hz refresh rate on the 4K resolution with integrated Intel GPU, you need Haswell CPU with the HD5000 graphics card, anything below that will only drive the 4K resolution at 30 Hz.

  • Mini Display Port connector for 2008 Mac Pro

    I have a 2008 Mac Pro (with 2 x DVI connectors).  Is there a graphics card with Mini Display Port connector that I can just wack in and use a 27" Apple LED Cinema Display?

    Which 27" display?  Current Thunderbolt model or previous mini-displayport model?
    For mini-displayport connections look at the apple versions of the ATI Radeon HD 5770 and 5780 video cards.  Both have two mini-displayports and a dual link dvi port.  The 5770 requires one aux poer adapter cable while the 5780 requires two.
    At present there is no way to connect the current 27" TB display to mini-displayport.  Only to another TB display or the 2011 computer's apple makes.

  • I am trying to connect my HDTV to my MacBook Pro using a Mini Display Port to HDMI and the TV seems to not be receiving any signal. Is there something wrong with my TV or Adapter?

    Whenever I connect the minidisplay port to the HDMI cable, my MacBook Pro screen turns blue for a moment and then nothing shows on my HDTV. I have tried to "detect displays" with each resolution listed, but none seem to work with my tv. Is there any way to fix this issue?

    I keep saying this over and over, in the hope that people who do a search will find it.  Apple cannot possibly test for or be reponsible for the bazillion combinations of adapter, cables, and TV's out there.  The only monitors that are 100% guaranteed to work with the MacBook Pro are the Cinema Displays and Thunderbolt Displays, because, they're made by Apple.  They're expensive, but they work perfectly.
    My guess is that you bought a cheap MDP to HDMI cable, or have a defective one.  From my reading of these boards over the past few months, cheap cables have a high failure rate.  And the regular priced ones have only a slightly less of one.  Try a new one.  Make sure you do not damage the Thunderbolt port.

  • FIX for Dell U3011 displaying YPbPr instead of RGB via display port

    I kind of hacked my way around and got my Dell U3011 to properly display RGB instead of YPbPr (or YCbCr) over a mini display port to display port cable for my MacBook Pro Retina 15"! WOOHOO! no need for that stupid $150 dual link dvi to mini displayport adapter anymore, which was incredibly flakey and sometimes the monitor turned on, and sometimes it didn't etc... lots of problems.
    Download the file from:
    http://www.8mmdesign.com/u3011-rgb-ypbpr-fix/DisplayVendorID-10ac.zip
    unzip into:
    /System/Library/Displays/Overrides
    It will create a new directory called:
    /System/Library/Displays/Overrides/DisplayVendorID-10ac
    Then reboot the system, and it should work. Go to system preferences, displays, color, and set the display profile to Color LCD.
    This will *ONLY* work for the Dell u3011 and it is completely UNTESTED. Use at your OWN RISK. But you should have proper RGB colors after doing this.
    Good luck!

    This post helped me: http://ireckon.net/2013/03/force-rgb-mode-in-mac-os-x-to-fix-the-picture-quality -of-an-external-monitor
    I have an Onkyo AV Receiver TX-NR414, I'm using the HDMI passthru (connecting Mac to AVR, then AVR to TV) and my Macs where giving bad colors.
    Connecting the Mac directly to the TV was ok.
    So the problem was the need to force the Mac to output RGB, the above linked blog post has a link to a Ruby script that will create a profile with RGB output. Follow the instructions and it will get it right.

  • Connecting to projector via display port

    I have been using the display port on W700 via HDMI cable to connect to my projector OK and then next day can not get either to talk to each other.  What might be wrong?  Have tried connecting both in alternate ways with cable - switching one and then other etc to no avail.  I did go to Presentation Director after using both and ticked "Capture Display settings" but unticking etc makes no difference and finally I uninstalled PD and reinstalled.

    Hi StormTiger,
    If you are having issues with the VGA out on your MacBook Pro, you may want to try the troubleshooting steps in the following article to see if you can isolate the issue. In particular, if possible you may want to test it with a different Mini-DisplayPort to VGA adapter to see if the issue is with the adapter or the computer.

  • Does my MacBook passes audio through Mini Display Port or not?

    I recently bought a Mini DisplayPort > HDMI adapter in order to display my MacBook on my TV. Other users of the same adapter publicly stated that they got video AND audio out, but I got only video.
    I've been searching this online for two days now and I still don't know why (I even searched this support forum, but I must admit that I got a little lost and decided to write my own topic). All I discovered was that some MacBooks have this capacity (to port audio along with video through Mini DisplayPort) and others don't.
    I'm using a white MacBook unibody bought new and latest on late 2009. It's the first model with multitouch trackpad and without FireWire port. Its model name is "MacBook 6,1", I guess.
    Does anybody know for sure if It CAN, in fact deliver audio+video through the Mini DisplayPort if I'm using a compatible HDMI adapter?
    Thanks.

    These models pass audio through the display port:
    iMac (Late 2009), MacBook Pro (Mid 2010), MacBook (Mid 2010), and Mac mini (Mid 2010) supply multichannel audio (up to 8 channels) and video signals over Mini DisplayPort. To connect your television or other HDMI devices to your Mac, use select third-party Mini DisplayPort to HDMI adapters that conform to the VESA v1.1a DisplayPort Interoperability Guidelines. The following adapters adhere to these standards:
    - Moshi Mini DP to HDMI Adapter with Audio Support
    - Griffin Video Display Converter (Mini DisplayPort to HDMI and DVI)

  • HP Elite 8300 Ultra Slim No Audio via Display Ports -Solution-

    This is a solution or a work around to getting audio functionality via the Display Ports on the HP Elite 8300 Ultra Slim and I suspect but cannot confirm as I do not have "other 8xxx models". Normally in the windows sound settings it will offer no options for audio via HDMI, etc with whatever drivers you so happened to install from HP or Intel when using the Display Ports on the machine.
    So this is what I did and I replicated it again to be sure.
    1.Install the Latest Intel HD 2500 Drivers first from the Intel Website first of course
    2.Download the HP Power Assistant Software v2.0.5.1
     http://h20565.www2.hp.com/hpsc/swd/public/detail?s​wItemId=ob_102595_1
    and install it and suddenly in the Sound settings in the Windows Control Panel you will find it now shows audio devices that are connected via the Display Ports via HDMI , weird I know but it works for any audio device connected to the DP pots via HDMI, etc.
    HP Customer Services told me categorically that it was not a function of the 8300 Ultra Slim supports due to the revision of display port it has so I am a bit annoyed that I had to search and search and actually fix it myself.

    Great discovery.
    I may experiment on my 8000 and 8200 Elite CMT's.
    I would have to remove the video cards I added though.
    FYI, so you don't have to go to third party websites, HP does have a direct link to the Power Assistant software you used.

    The bug is known, and a patch has been submitted: https://bugs.freedesktop.org/show_bug.cgi?id=80151. There's been no update since friday, so I wonder what the current status is, or if it's up for review at all.

  • External 4k monitor says no signal from display port

    HELP...
    I have a late 2009 27" iMac running 10.10.2 Yosemite, i bought an ASUS PB287Q 4k monitor to extend my desktop. I have connected it by MDP to DP and the Mac recognises the ASUS, shows it as a display and tells me how it is connected but the display keeps saying "display port no signal"
    If i run bootcamp and boot into windows 7 Ultimate on the same iMac the screen works perfectly giving me a 4k screen at 2160p to work on alongside the iMac with the same Display port cable.
    If i use OS X with a MDP to HDMI connector the screen works as it should but with a max resolution of 2560 x 1440 only.
    I have unplugged everything and re-connected, tried turning on the ASUS at different times, reset P Ram but still it will not work?
    Obviously every part is working but just not from OS X
    The ASUS is also set to display port 1.1
    Please can anyone help????

    Hi Brett,
    Thanks for your response, I'm on an iMac not Macbook but checked your link, All my software is up to date and there is no updates for the Asus and nothing for the mini dislayport to display port cable.
    Everything works as it should via display port if i run bootcamp into windows 7 just not from OS X so would seem like a Mac Graphics driver issue perhaps??
    I was hoping it would be a glitch that would correct itself by unplugging the cables or resetting the P Ram but no such luck so i am open to any other sugestions.
    The iMac can see the Asus at all times just doesn't seem to send the signal to the Asus?
    I would be happy to supply any logs that may shed some light on this issue.
    Kind Regards
    Mark

  • Macbook Pro to LED Cinema Display
