MacBook Pro Mid2012 does not detect external monitor

After i upgraded to MAVERICKS now using my " BELKIN HDMI TO THUNDERBOLT ADAPTER "
when i connect it to TV the monitor flashes black and nothing happens no signal on TV go to settings display and sound there is nothing and when i disconnect HDMI it flashes black again ,,, help please ..
i doent know if its from MAVERICKS OR HDMI CONVERTER OR SMT TV OR THUNDERBOLT PORT

I have a problem connecting external display (Dell U2311H) to my 13" MacBook Pro (Early 2011).
I use Tecklink Mini DasplayPort to HDMI adapter (http://www.techlink.uk.com/products/wires_cables/wiresmedia/wiresmedia_media/wir esmedia_mini_displayport_plug_to_hdmi_plug), but since U2311H doesn't have HDMI input, I also use Manhattan DisplayPort to HDMI Adapter (http://www.manhattan-products.com/en-US/products/8101-displayport-adapter).
And nothing.
The display is not detected, no picture or even external monitor presence at all.
I even reset PRAM, and installed 10.8.2 Supplementary update.
I also plugged and unplugged all I could, with no luck.
As I can see on Apple discussion, it is a common problem with 2011 MacBook Pro's.
It seems like the problem is in Thundebolt port, it somehow does not work properly.

    I have a MacBook Pro 13'' early 2011 runing Lion 1.7.2.
    I have an HP v185ws external monitor connected via an Apple Thunderbolt to VGA connector.
    Since last month's Thunderbolt firmware update, my external monitor is no longer detected.
    Does anybody has a solution to this problem?
    Thanks.

  • Macbook Pro(Mid-2014) Not Detecting External Monitor

    Hi everyone, I'm trying to connect my MBP to an external monitor via HDMI. Since my MBP has an HDMI port built in, I'm not using any adapters between it and the monitor. But nothing is happening when I connect the HDMI cable, my MBP does not seem to detect it. I have tested my monitor with that HDMI cable on a desktop PC, and it all works without any issues there, so I reckon it must be something on the MBP end of the connection. But what could it possibly be? I have looked through forums and read countless threads about external display problems, but have not found any info that could identify the problem. I have tried booting my MBP and/or turning on my monitor before and after connecting the HDMI cable, and there was never even a hint of detection.
    I'm running OS X Yosemite 10.10.1, and the external monitor in question is an HP Pavilion 27Xi in 1080p.

    I have problem, when I connect my laptop on external monitor LG Flatron W 2240. Laptop does not detect. I make conection with VGA cable (cable checked and it works). I try to reinstall my grphic driver, but it does'nt help. I use graphic driver for Windows 7 Professional 64 bit.

  • MBP does not detect external monitor on DVI connection...

    (2007) MBP C2D 2.33 15", OSX LION 3gb.  Worked fine till about 3 days ago (right after installing the last round of updates).
    My external monitor now fails to connect on DVI cable. Since it also has VGA, I was able to test this way with a DVI to VGA adapter and that worked perfectly, but the vga gives a lower resolution. Having estalished that the graphics adapter and the monitor were okay, I looked for other issues.
    Starting the MBP in clamshell mode, it found the monitor on DVI. Then restarting normally, it all worked fine, UNTILL the MBP went to sleep. when it awoke, no external. Plugged, unplugged, trashed display prefs, nothing, though it does still work via DVI-VGA.
    I don't think having to clamshell everytime is a workable solution, but I NEED MY DESK SPACE!
    Any thoughts?

    Yesterday, having had the problem become far worse, I too tried PRAM/NVRAM clearing (SMC reset so many times I can't count them). Then, in desperation I purchased TechtoolPro 6 and ran it. Everything s working well now, and in fact the video issue cleared up while techtool loaded, it didn't even wait for me to run the thing!
    More: About 3 weeks ago, I made a HardDrive image from an older white macbook so I could repair its hard drive. After doing that job, I (thought I) deleted the image from my MBP, but the disk still showed 80Gb used that wasn't before. So while I thought I had 130GB free, I was only showing 50. After running the directory rebuild, I now have 175gb Free! So the directory was keeping track of 95GB that WASN'T there! I suspect this had something to do with my problems.  Then running the Defrag and Optimization routines, my 2007 MBP is running like a brand new machine. Other things that had been buggy (like the right click on my magic mouse) are now working like they should.
    Recommended highly!

  • MacBook Pro does not sense external monitor (Panasonic HDTV in my case) via thunderbolt-HDMI connection...Is update 10.8.3 helping anyone?

    My MacBook Pro (newest model in 2013 so far) does not sense external monitor (Panasonic HDTV in my case) via thunderbolt-HDMI connection...Is update 10.8.3 helping anyone else who has this issue? I returned my multiple HDMI adapters after figuring out it had to be an Apple issue n not the adapters so I can't check it myself now.
    Thanks!

    I have late 2012 MBP 13" and connect to my Panasonic Plasma correctly.
    But using the same cable, can't connect to an LG 47LM6200, the MBP detects the TV, the screen blinks blue, but the TV shows "no sinal detected" message.

  • Thinkpad Edge S430 - Windows does not detect external display connected via HDMI

    On a Thinkpad S430 with HD4000 integrated graphics, an external display connected via a HDMI cable is not detected at all when using Windows. The system is fully updated as of the time of posting this message, both via the Lenovo Update tool as well as Windows update.
    The Intel driver version is 8.15.10.2696. It appears that this is the latest version, since it does not offer an update when I try to auto-update it via Device Manager.
    NB: I am running Ubuntu 12.04 with kernel 3.4.0 on the same machine, and the external display works perfectly fine with this software configuration.
    Hence I think that it's very likely that this is a Windows-specific driver issue.
    Would Lenovo happen to have a driver update in the works? Alternatively, I will be thankful for any suggestions about possible resolution of this problem.

    You haven't identified the version so I can't tell if offering you contact options for Adobe Support will be of use to you.  But they will likely be your only hope of getting resolution unless you just happen to be using the wrong number as the serial number.

    Have you tried resetting the PRAM? shutdown the machine, hit the power button then hold down the option and command keys with your left hand, while holding them down with your right hand use your pinky to hold the 'P' key and index finger to hold down the 'R' key. hold them down until you hear the 'bong' sound twice then release the keys and let the machine bootup.
    Also try resetting the SMC. Shut the machine down. Hold down the 'shiftctrloption' keys with your left hand, right hand hold down the power button for 10 seconds then release all. Power up the machine as normal.
    Hope this helps. Pls update us and let us know if that helps!

  • Display Preferences does not detect dual monitors

    Display Preferences does not detect dual monitors.
    There is no workaround here.
    Only a prompt update from apple will solve this.
    Any level 5 geniuses I welcome your guidance... please prove me otherwise.
    thanks

    Hi marconi de baloni,
    Thanks for the question. Based on what you stated, it seems like the computer is not recognizing a second display. I would recommend that you read this article, it may be able to help you resolve or isolate the issue.
    OS X Yosemite: Connect multiple displays to your Mac
    If a display is not recognized, choose Apple menu > System Preferences on the primary Mac, click Displays, then click Display.
    Open the Display pane for me
    Then click the Detect Displays button.
    You can also try putting your Mac to sleep and then waking it.
    Thanks for using Apple Support Communities.
    Cheers,
    Mario
