Tv Receives No HDMI Signal from Macbook

Hi Everyone,
Recently I bought an HDMI cable and a 'MiniDisplay Port to HDMI Adapter' from Rocketfish in order to use my Tv as a large monitor. However, when I plug the adapter into the port followed by the HDMI cable my Macbook's [Late 2011 model running with Mountain Lion 10.8.2] screen turns blue for a short moment and the TV seems to acknowlede the input because it immediately pops up a window stating that there is No signal, sometimes also the screen just goes black. Sounds nonsensical yet the tv does acknowledge the Imput by stating that there is no Signal.
Has anyone ever had this happen too ? Is there perhaps a better way to connect a Macbook to a TV ? At this point I am willing to invest a lot more money just to make it work.

Hi, mtobler!
I have the same problem. The only difference is that I am trying to connect to an external display using Mini DisplayPort to VGA adapter. I have tried with two different displays - a TV, Samsung C8000 TV; and TV-Monitor, Samsung SyncMaster P2470HD, both of them with no success. When I connect the adapter the screen turns blue for a second, the TV, just like yours, says 'No signal' and the Mac itself does not find any external displays. I have tried a variety of solutions - resetting PRAM, SMC, but nothing helped.
The AirPlay is not an option for me, because I want to use the Mac with projectors (HDMI adapters are not a solution, because most of the projectors I use are old and have VGA ports only).
I will try connecting it to a projector tomorrow. Let's hope it runs smoothly.

    What model MacBook Pro?
    The mini display port on earlier Apple computers only support video. See:
    About Mini DisplayPort to HDMI adapters
    Also, if you go to System Preferences>Sounds>Output do y see HDMI or Min displayport as an Audio out option?

  • I have an HP2055dn printer that isn't receiving a wireless signal from an Mac Airport router.

    I moved the printer and it doesn't receive the wireless signal.  Does the printer need to be attached to my computer for it to receive a wireless signal from another computer? 

    Hi,
    Do you use access point (AP) for your network ? The printer needs to be close to the AP, not computer(s). One option is to have a booster/amplifier but this costs money and time.
    Regards.

  • Capturing HDMI signal to MacBook Pro for editing in FCP

    I have a ton of old home-recorded VHS tapes that I'm hoping to capture to FCP editable QT files. I'm considering purchasing a Panasonic BluRay/VHS combi deck, the DMP-BD70V, because it supposedly upscales old VHS tapes for display through the HDMI cable output. My question is, will I be able to feed the digital output of the HDMI cable directly into my MacBook Pro 15" (vintage September 2007) laptop, or will I still need some sort of card to make the HDMI signal palpable to my computer?

    The short answer is - not unless you are willing to fork over $600+ for the necessary converter. Probably the least expensive such converter is the Canopus ADVC-HD50, which can convert the HDMI signal to HDV and feed it to your Mac via FireWire. Something to consider is that you will be going through multiple conversions this way - VHS -> upscaling to hidef via HDMI -> conversion to HDV -> possible conversion to AIC or ProRes. IMHO not a great workflow, as it's likely to degrade the quality to a noticeable degree, especially that upscaling step.
    Something to consider - the quality is limited by the original VHS tape & recording. Even DV is significantly higher quality than VHS. You will be better off converting directly from the analog VHS to DV using a Canopus ADVC-110 or 300 or similar analog-DV converter.

  • No HDMI signal from apple tv

    I recently purchased an ATV (in the USA - I live in Europe) and I notice that ATV doesn't seem to 'connect' to my TV, ie. the tv consistently shows 'no HDMI signal', or will sometimes show part of the relevant ATV menu screen momentarily and then disappear. The remedy is to reboot ATV or disconnect and reconnect the power cable. Does anyone have a remedy for this?

    I have the same issue. My Apple TV works when I reboot (unplug/replug) it. But if I attempt to change the resolution, put it on standby, or if I switch to another device and return to it later, I get an intermittent signal. Every few 4-5 seconds the menu/screensaver appears and disappears pretty quickly. If I reboot and watch a movie immediately it works fine.
    My TV is a Olevia 542i LCD HDTV.

    Anyone have any ideas? Could the AppleTV be defective?

  • No HDMI Signal from MBP to Samsung HDTV

    I have a late 2013 MBP Retina and trying to hook up my laptop to my Samsung HDTV via HDMI.  I plug the cable in and nothing.  The Mac doesn't even see the input at all.  I have tried a couple different cables and same result.  I know the HDMI port works on the TV as I have my receiver running through it with no problem.  I also know the port on the MBP works because I use an HDMI monitor at my desk just fine.  I don't know what is going on, but this is not working at all.
    What gives?  Any help is appreciated.

    Try the Command + F1 keyboard shortcut.

    Is your Mac plugged into AC power? If not, do so.
    GFx CardStatus can show which video card is in use- http://gfx.io/
    I don't know if the Retina intel/integrated card can drive external displays, but the discrete card can.

  • My iPad suddenly stopped receiving cell signal from Verizon and in the top left corner it says Invavid SIM where it used to say 3G

    MY 2 week old IPad 2 suddenly stopped receiving a cell signal from Verizon and in the top left corner of the screen it says Invalid SIM where it used to say 3G.  Why did this happen and how do I fix it?  Still works on WIFI...

    Why? Who knows. You could try reseating the SIM to see if this helps. If not contact Verizon.

  • Can I use Airport Express to extend signal from my Airport Extreme and then run Ethernet from Express to my TV which requires ethernet to access internet?

    As stated in title. I want to access Netflix but my TV requires ethernet connection. I would like to use Express to repeat Exreme sigal and then to TV via Ethernet. I only have one access point in house for cable modem so I'm using Extreme to broadcast though house. Will need to be able to input network key for Extreme secure network. Thank you.
    Mike

    Are both your AirPort Extreme and AirPort Express 802.11"n" devices?
    If yes, you can configure the Express to "extend a wireless network" and it will  provide more wireless coverage and the Etherent port will be enabled so that you can connect an Ethernet device.
    This assumes that the Express is located where it can receive a strong signal from the AirPort Extreme.

  • If I purchase a second Airport, will it strengthen the signal from the router in one part of the house , so that the printer, in a basement can see it?

    I have a router in my upstairs, main floor of the house.   My iMac connects easily to the router, but the printer does not.  If I purchase a second Airport, will it strengthen the signal from the router so the printer will connect wirelessly to the network?
    I had the printer connected to the iMac by USB , but when I upgraded the iMac to Maverick OS10  my scanner no longer worked, the more I fussed with it the less productive it was.   Now the printer no longer is available at all.   The computer does not see it.  
    The message when I turn them on is that the USB is not compatible.    I unplugged the USB cable,  and would like to connect wirelessly.
    Thank you for any hints
    Carol Havens

    If you have an Apple router now providing your wireless network, you could add another....like an AirPort Express, for example....to "extend" the signal wirelessly and provide more coverage.
    This is always a bit tricky, because the AirPort Express would need to be located where it can receive a strong signal from the main AirPort wireless router.
    For example, if you need more wireless signal in a bedroom at the end of the house, you would locate the AirPort Express about half way between the main AirPort router and the bedroom.
    On a side note......only the print function will work when you connect an All-in-One device to the USB port on an AirPort, so connect the All-in-One using wireless for full functionality.

  • Tv won't recognize hdmi from macbook pro, but will from ipad

    I have a new Toshiba TV (40L5200U) that will recognize HDMI input from an IPad, but not from a MacBook Pro (running 10.6.8).  I'm connecting through a Rocketfish Mini DisplayPort to HDMI Adapter (RF-AP305), but the TV says "no video signal."  Display Preferences shows 1024x768, which the TV user guide lists as an acceptable input (XGA), but when I detect displays the computer doesn't recognize the TV.  I can't see an Arrangements tab.  The computer does give output through this port to a VGA adapter for a projector.  Any suggestions?  Thanks.

    It is vital to push the Mini DisplayPort adapter into the Mac socket until essentially ALL of the metal is inside the socket.
    Use About This Mac > ( More Info ) > Displays to examine the NAME of the display attached. Until you get the make&model popping up there, you have not made a solid connection.
    "Supported resolutions" for many displays are not supported in the same way on each of the available ports. 1024x768 mat be an excellent VGA resolution that does not work at all across HDMI. Be certain [√] Mirroring is turned OFF to allow the displays to be set independently.

  • XBR-55x900A software update today. Now saying no signal from receiver.

    Today I had a Sony Software update download on my XBR-55x900A. The TV now says that it is not receiving a signal from the Denon receiver. Everything worked fine until the update. I have done a hard reset, reset the factory software, bought new HDMI 2.0 cables and still not working. I can attached the cable box directly to the TV and it works. Would really like to get everything back through the stereo receiver.

  • Disabling the MBP's ability to receive signals from remote control?

    I own an AppleTV, my roomate uses a Macbook and I have the Macbook Pro, and they all use the same remote control and signal. Anytime we use the remote for the AppleTV it sends our notebooks into Front Row. Is there anyway to disable the mac's ability to receive the signal from the remotes?
    Thanks.

    Hi,
    What you need to do is pair each Apple Remote so that it's only recognised by the Mac it's paired with. The following Apple KB Documents will guide you on how to achieve this:

  • MacBook Pro 15" losing HDMI signal intermittently

    MacBook Pro 15" Late 2011 (Mavericks 10.9.4); 4 GB ram.  I am running HDMI to a new video projector.  The HDMI signal is lost periodically for about 1-2 seconds and then comes back.  It occurs about every 5-7 minutes (about 20 times during a 50 minute lecture).  It loses both video and audio. Screen goes black but no displayed messages.  I have read a variety of other posts with similar symptoms with various computers (e.g. Mac mini) and even with DVI cable use.  In my case, I've used two different HDMI adaptors so it's not the adaptor. I'm pretty sure it's not the HDMI cable itself.  (A fellow professor does not have the issue with his PC and he uses the same equipment.) Neither the computer nor the cable is touched.  (I have another colleague who reports the same symptoms in his music lab.) Bottom line is that it's a distraction to my students and it's occurring off different Macs in different locations.  This means to me that it may be something with the particular generation of Macs we're using.  Looking for help to resolve the issue.

    Assuming this is your machine - MacBook Pro (15-inch, Late 2011) - Technical Specifications you are using a DisplayPort (from the Thunderbolt/DP port) to an HDMI adapter. Non-Apple adapters have issues.
    The other factor is that there are GPU issues with the AMD - problems with amd gpu on early 2011 macbook pro (there are many threads like this).
    Either issue may be impacting your Mac connectivity.  The third-party adapters may not be able to drive signals consistently.
    Can you test with an Apple-branded DP-to-HDMI adapter and the 50' cable?
