Thunderbolt to HDMI NOT WORKING

Hiya,
Can't get video or audio on an LG TV. MAC PRO DETECTS TV, lists it's model number in settings, but doesn't work.
We bought lead from apple store.
Thanks for any suggestions.....

There is no iMac Model 3.1. There is a MacPro model 3.1, is this what you are referring to?. See the link below to help clarify:

  • HT2998 connecting MacMini to display with after market thunderbolt-to -HDMI, not working

    just purchased the mac mini, purchased after market thunderbolt to HDMI cable. connected from mini to display monitor. nothing comes up, display reads no VGA signal.

    Does the monitor have a way to change input source?
    I had this same issue when I first tried with my MBP, I had to do an SMC reset to get it to work.

  • My thunderbolt display is not working with my MBP retina 13''

    Hi,
         I just received both a new macbook pro retina 13'' and a thunderbolt display. Everything was working properly yesterday but today, I have no clue why, the thunderbolt display is not working anymore.
         . the power supplier for my laptop given by the thunderbolt display is still working;
         . when I don't connect my laptop through the thunderbolt connection, I can use the usb sockets as power supplier , for my phone, for instance;
         . as soon as I plug the thunderbolt cable, the usb socket is not feeding any more my phone, whereas the screen is not displaying anything.
         . If I take a look in the system report, in the thunderbolt tab, there is "no device connected"...
    I restarted plenty of time my laptop, took care to reinitialise the SMC as well as the PRAM, and nothing changed. I also disconnected the thunderbolt display, waited few minutes (and more), but nothing changed, again the black screen.
    Has somebody an idea?
    Thanks

    which model air do you have?
    try both a pram and smc reset
    plug the monitor into a different electrical outlet and a different port on your Mac (if you have multiple tb ports)

  • Macbook Air (mid 2012) Thunderbolt to HDMI Stopped working

    Hey Guys,
    I have searched this issue and have found several threads some 50+ pages long but I could not find a soluition. I currently have a macbook air 13" mid 2012 model.
    Problem: I was using a thunderbolt to HDMI cable to watch movies on my SONY Bravia tv and it was working fine one day and after I updated my software to mac OS X 10.7.5 it stopped working. All i get on my TV is "no signal" and the screen on my MBA starts to flash blue every now and then.
    I took it into the genius bar and they plugged it in to their system and it seemed to work, so the guy said to get a new cord.
    I ordered a new cord and tried it at home and its still not working. After searching the forums I see that alot of others seem to be having the same issues and I am pretty sure its related to a software issue seen in the thread below.
    https://discussions.apple.com/thread/3196192?start=75&tstart=0
    Anyone have a similar issue and found a fix??

    A new Mac is in warranty for 1 year from the date of purchase. Why not use it?
    You may have to take the computer to the Apple store to have it checked out.
    All hardware related issues should be brought to the attention of Apple.

  • My thunderbolt to hdmi cable worked once but then stopped

    so i bought a thunderbolt to HDMI adapter and it work great but when i took out the hdmi and put it in my console id didnt work when i checked if it would work with the adapter is didnt so this adaper stoped working a broke my HDMI cord

    Hi, how did you solve your problem? Im having the exact same issue.
    "When connected to the TV via the Thunderbolt-HDMI cable, a blue screen briefly appears on the Macbook. However, when looking in System Preferences/ Displays, there is no trace of any external screen. Many of the forums I have read say there should be an "Arrangement" tab, but this is not appearing on mine."
    plus the cable works on my boyfriend's Macbook Air, which is an older version than mine.
    I have the Macbook Air Version 10.8.4, bought July 2013 (newest version).
    Can someone help me?
    Thanks

  • Satego x200-21u - Remote and HDMI not work on Windows 7

    Hey
    I have a problem with win7 and the remote that was delivered with my notebook when i bought it
    I installed all drivers from the toshiba homepage for win7. I also installed some of the winvista driver, like the webcam- and the touchpad drivers.
    The only two things, not working are the remote and the HDMI-Sound output.
    my remote doesnt work with win7. and if i connect my notebook to my flat-tv via HDMI-Cable i only see the picture but hear no sound.
    I changed also the settings in the soundoptions in win7 from default to Digitalaudio (HDMI) but it doesnt work anyways..
    can someone tell me which drivers i need to install these two or what i have to do, to make my remote and the HDMI output work?
    thanks alot

    Hi mate,
    This is really strange to say because this notebook is a little bit older and therefore there is no official Windows 7 support I think...
    Do you have yellow exclamation marks in device manager at the moment?
    For HDMI I think chipset, display and sound driver should be installed. Maybe you can get one on the Intel page directly.
    Make also sure that the newest BIOS version is installed on your notebook.

  • Macbook mini-DVI - DVI - HDMI not working with My 32" Vizio

    Okay so my Macbook mini-DVI - DVI - HDMI is not working with My 32" Vizio. I've connected an 18 pin plus one slot DVI to HDMI cable to my 32" Vizio HDTV, this cable is connected to my macbook via a Mini-DVI to DVI cable, this one has 24 pins plus one slot on the DVI side. My Vizio display is blue, no signal, it reads. I'm wondering if the reason it's not picking up the display is the lack of pins on the DVI to HDMI or because I dont have any display options aside from screen size and color on my display menu. BTW I hit the detect display button and nothing happened.... I know I just wrote alot here but hopefully someone will read it and come to the rescue. thanks

    Oops, I guess all I had to do was restart my macbook. I feel like an idiot.....all is well.

  • Update to Mac OS X 10.8.4 HDMI Not Working?

    Hi,
    I have a 15" MBP Retina and after I updated to Mac OS X 10.8.4, connecting to a tv through HDMI no longer works.
    I have tried different cables, different tv's. When I connect my Lenovo laptop to my tv through HDMI, it works. Thus, I know it's not a tv or cable problem.
    What happens with my MBP is that when I connect the HDMI from my tv to my laptop, the screen flashes blue but nothing happens after. Nothing shows up in the task bar (ex. mirroring options) and nothing shows up on my tv (it has no signal).
    I'm guessing the latest update created this bug. Anyone share the same problem?

    Thx! This looks like a good link. Somehow I got it to work without any tricks, it just worked all the sudden. Frikkin computers! I'm very surprised I have to choose audio-source when I connect my MacBook to my TV, I naively hoped that this was going to work out for itself (magically) once I've connected those two and chosen screen output.
