Mini Display Port has completely stopped working

So I bought a Mini Display Port to HDMI adapter and it has worked perfectly well for more than a month. That's until 3 days ago. Out of nowhere I plugged my HDMI into the adapter and the power led of the monitor turned on and after a few seconds of reading, "No Signal". I have to hold the power cord in the more odd angles to get even for the screens of mirror, and even in this case, the screen is static at 80%. I looked online and tried every single tip or solution I've seen without success. All my HDMI cords are fully functional as I tried each one with my PS4 and works perfectly, so this isn't the issue. I've never had problems like this with any other Apple computer. Probably because no other computer using mini display ONLY ports. If anyone has had this problem and found a solution please let me know, if I can try to get this working. I have a MacBook Pro 15 in. mid-2012 with the processor i7 under OS X 10.8.5

This suggests a possible problem with the cord.  I would like to make an appointment with an Apple store genius bar and I tested the unit and the power cord.

Ciao.

  • Target display mode has suddenly stopped working

    I've been using display mode target using a cable thunderbolt between my iMac 21.5 inches (end of 2012) and Macbook Air 13 inch (early 2014) for about six months.

    I had a few weeks off and had to return to find that I can enter is no longer target display mode! When I press Control-F2 on my keyboard connected to my iMac, that nothing is happening. I also tried Fn-control-F2. I tried different ports in case one of them is damaged. But nothing helped.

    Anyone has any suggestions as to why target display mode would have stopped working so suddenly? I really like the feature of double screens between my macbook and iMac and would really like to come back!

    Thank you.

    I know target Display Mode will work, but only if I use the command-f2 from the login screen. After the connection, the command does not work. have you tried?

  • Touchpad has completely stopped working

    Hey, my touchpad completely stopped working. I tried to download the driver and restart and the stuff, but nothing seems to work. There was formerly an icon for it down to the right on the toolbar, but that's even more here, it's like the software so that it just doesn't even exist anymore.

    Can anyone suggest a solution please?
    Thank you

    Hello!

    You can disable and enable the touchpad with FN + F9. Select this check box, because maybe it s disabled.

    Have you tested an external mouse? You have the same problem with it?

    Good bye

  • My keyboard for my Acer aspire switch 10 has completely stopped working

    I use my Acer 10 for about six months and had improved to win 10 just now with no problems.  This morning the keyboard stopped working.  I checked the Tablet contacts, clean them with a brush and a cleaning and not restarted, no chance.  The keyboard when it starts allows me to enter the PIN code and I have a USB mouse attached to the keyboard that works, but none of the keys work when I am connected to Windows. If the screen times out and I try to enter the PIN code again, nothing.   I can navigate around using the mouse, but not have the ability to enter information on keyboard.  I'm stumped and would apprecaite any suggestions welcome.  Acer has been great so far?

    I solved the problem!  It turns out it is 10 Windows that caused the problem.  Filter keys were turned on somehow and they disable the keyboard for users with disabilities. I discovered this on another machine when it happened too, but this time a unrecognized icon appeared in my system tray.  The icon has been for these filter keys and when I turned off their keyboard is back.  How this stupid thing got switched on I don't have a clue.  The original pc with the problem did not show a filter key icon in the system tray, so I was puzzled, did not know they existed.  Something for others to check if this is the case for them.  Thanks for your help.

  • The last 3 times I clicked on auto updates of firefox firefox has completely stop working and I have to open the Explorer and again to download firefox.

    I'm afraid to update firefox since the last 3 times I did so firefox stop working and had to be reinstalled.

    I'm glad it works again. This is the important result and thanks for posting back.

    Repeated to uninstall and reinstall Firefox often do not help.
    Clicking on the pop-up of unknown or doubtful origin, it is always a bad idea.

    Screenshots will help if you are still having problems.

    Connects to any future reference is not to the internet, after a new installation may be related to problems with the firewall or your security software not recognizing Firefox.

  • Stream laptop HP 11: laptop has completely stopped working

    I've been on gmail, I try to print an e-mail when I got a message saying had stopped the page and I would like to wait or kill him. So I pushed to kill and took me to the desktop. On the desktop, I couldn't do anything to work so I pushed the power button. The power button starts blinking and the screen went black. Then I pushed the button of power again and the screen came blue and it won't do anything.

    My daughter also said, that the left speaker is not working.

    I'm on a tablet now and it does not work well most of the time, so if it takes a few minutes to answer, it's because I have a problem with the tablet.

  • Windows Update has completely stopped working

  • Family safety on Windows 7 has completely stopped working, even if she pretends to be on

    Help, please!  The Windows Live Family Safety filter worked well on two of my computers for a few months.  All of a sudden it does not filter anything, well that Family Safety site shows that the filter is activated and the work for each account.  I tried to turn it works, change settings, updating / refreshing the filter, etc., and it did not help.  I discovered and removed a Trojan horse (win32/Neop! gmb) and some adware (win32/BetterSurf) that were on my computer.  Then I tried to uninstall the filter of parental control on both computers, closing my account of the safety of the family and he put everything back in place from scratch.  That does not help either.  The filter will still let us get any site and see adult pictures or videos, even if the filter says it is on and functioning "normally."  I don't know what else to try.

    I heard this on another post, and it WORKED for me also!  I logged on my account live.com and udated my name in my profile.  I don't know if that it or if MS has solved something but I can not connect on fss.live.com.  Please share and please post if it worked or not.

  • Dell XPS 12 Mini DisplayPort seems to have stopped working

    Hello

    My Mini DisplayPort seems to have stopped working. I can connect on the same monitor of the ultrabook even through the USB port. However, because I'm a geek of database I need up to 3 screens. So when I try and connect to my Mini DisplayPort monitor the screen resolution tab in the Control Panel recognizes the display. However, the actual display is empty. Mini DisplayPort has worked well for the last 8 months or so, but stopped working tonight.

    The external monitor is; -Samsung; SyncMaster 941BW/940BW\199BW, SyncMaster Magic CX915BW (Digital)

    Any help would be greatly appreciated.

    Kind regards

    Kieran.

    I replaced the cable and now it seems to work.

    Thank you

    Hello

    I think that it of really not easy to say what could be the problem
    I can only suggest

    Depending on your message, nothing appears on the screen not even if you would not try to boot from the recovery disk or other bootable discs. Is this good?

    You could try a procedure;
    -Remove the battery and unplug the AC adapter from the portable computer
    -Wait several minutes (about 30 min)
    -try to boot the machine

    Check it out, but if you will not be successful then a hardware malfunction could be the cause of your problem, and you should ask the local ASP to help him!

    Good bye

  • X 1 carbon 20BS do not recognize the Mini Display Port

    Hello - I have recently acquired a Thinkpad X 1 carbon 20BS with a new installation of window 10. While I am able to connect to external monitors via HDMI, I was unable to do that via the Mini Display Port. Connection of a monitor to the Mini Display Port didn't do nothing - the monitor is not identified by Windows.

    So far, I have installed the drivers of:, but it did not help. Any help to find ways get the carbon X 1 to recognize the Mini Display Port will be really appreciated.

    Thank you in advance.

    Jake - Thanks a lot for the reply. Happy to report that I was able to get the mini DP to work and he recognizes the compatible monitors very well.

    I tried to find a solution to link the Thunderbolt display carbon, but unfortuantely it seems not to be a Thunderbolt controller that is compatible with the mini DP carbon.
