"No signal" from MBP on LG TV via HDMI

Hi everyone,
I have a 4.5 year old MBP that I want to connect to a to an LG TV via HDMI. The MBP has a DVI port and also came with a small white adapter to connect to a VGA cable. I purchased a VGA to HDMI cable and then connected the MBP to the LG TV using the Apple adapter and new cable. No matter what I try, the LG TV only shows "No Signal" on the screen. The farthest I have gotten is for the MBP to recognize the LG TV when I mirror displays. I get two panels, one with the resolutions for the MBP and the other with the resolutions for the LG TV. Nothing at all on the LG screen except for the annoying "No Signal" message.
I have tried both HDMI ports on the back of the TV and made sure that I clicked the correct one on the LG TV. I've turned both devices off and on and connected and disconnected cables in different order to try to get the TV to receive visual input from the MBP. As a matter of fact, the more time I invest in this, the worse the results. Now, when I try to connect the two devices in this way, I get nothing on my MBP except for a desktop picture and the cursor. No dock, no menu bar, no files. Nothing but the empty desktop. I have to force the MBP to shut down by holding down the button and then disconnect cables to get it to come back to life again.
Is there something I'm doing wrong? Should I try a different cable, such as a DVI to VGA, which would not require the Apple adapter?

Hello @ShiningLights,
Welcome to the HP Forums, I hope you enjoy your experience!
I have read your post on how your TV is not able to detect your HDMI connected notebook, and I would be happy to assist you in this matter!
To ensure your system is configured correctly to connect to your TV, I recommend following this document on Connecting a Monitor, Projector or TV (Windows 8). I also suggest trying a different HDMI cord to ensure the issue is not with the cable.
Please re-post with the results of your troubleshooting, and I look forward to your reply!

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.

How to broadcast Wifi Signal from MBP when using AT&T mobile card.

I have a Macbook Pro and access the internet via an AT&T wireless modem card (USB Quicksilver). Is there a way to broadcast a Wifi signal so that I can get internet on my new iTouch ?
Thanks for any help !!
Cindy

Yah, Seattle: I see what you are talking about: when you try to enable share, the message is "you haven't enabled a port to share", and the only offer is ethernet? I do share my wireless AT&T AirCard. Are you sharing with a PC, or more Macs, on Airport? It took me a while, when I first enabled the share on Airport. From System preferences > Internet and Network > Sharing, there is no joy. First go to Network Preferences: enable Airport; whatever it takes; Network name you self-assign. Now when you go to SysPref > Sharing > and check Internet Sharing, you get another scolding: "You cannot share 'cause no ports; or share from Airport to computes using ..." Go to Network Preferences > Airport > Network Name > Create Network, or if the other computer is up and around, > Join Network. Mine werke,s but it was ugly getting it up to a PC wireless ... I got it almost there and then had to go 128 bit encryption password etc to make the (corporate) PC happy. This is not plug and play ... Keep trying and take notes and post back.

Downloading video from Canon Vixia HV 30 via HDMI to Mini DisplayPort

Laptop Specs: White MacBook 10.6.6, 2 x USB, Mini DisplayPort, Audio In/Out
Camera: Canon Vixia HV30
I recently upgraded my MacBook and my new MacBook doesn't have a firewire input. I had downloaded video from my Canon Vixia HV30 to iMovie using an HDV/DV to Firewire chord.
Since the new MacBook doesn't have a firewire input, I tried an HDMI to Mini DisplayPort chord. The MacBook (via Finder, iMovie, and Final Cut Express) doesn't recognize that there is a camera connected.
Any ideas?

That's a miniDV camera. MiniDV ALWAYS needs Firewire - there's no way around it. There are no USB to Firewire converters. If you very recently (last 14 days) bought the Macbook, and you absolutely want to continue using the camera, you could perhaps return the MB and see if the 13" Macbook Pro is within your budget.
Modern consumer HD cameras tend to use USB connections.

BLUETOOTH only picks up signal from mac computers but nothing else???

does anyone have any suggestions as to getting my iphone to pick up other signals from cell phones or headsets via bluetooth every time i try and search for a device nothing happens but when its near a mac computer it conveniently picks up a signal???

You won't pick up bluetooth from another cell phone since the iPhone does not include the bluetooth profile for transferring files or data with a cell phone or with a computer, but you should be able to pair your iPhone with a bluetooth headset that is set to be discovered.

Macbook Pro to HDTV via HDMI no audio with video

So I plugged in my MBP to my tv via HDMI this weekend and for some reason I was getting no audio when trying to watch a video online. I tried multiple websites to see if that was the issue, but nothing seemed to work. I was using Chrome but didn't try any other browsers. The video played but I would get no audio through my tv. The kicker was that when I played a song from iTunes, the audio would work just fine through the tv. Has anyone ran into this problem?

Morning kirstenpolley,
Thanks for using Apple Support Communities.
If you know the hdmi cable is good.
You may want to try a different input channel or a different display adapter.
For more information on this, take a look at this article:

MiniDP port doesn't play sound via HDMI

I have connected it from the computer to the HD tv, and the video works. But the sound will not transfer, The sound preferences doesn't show any outputs but the internal speakers, and I checked the MIDI setup Utility, and it also did not show it as an option.

Hi, guidino. I have a late-2008 unibody MBP like yours, and I don't expect Apple will ever enable our mini-Displayports to output audio signals. But there are adapters that will combine audio and video signals from our machines into a single HDMI cable and resolve the problem you describe in your post. Here are three:
This one draws 5.1-channel optical digital audio from the headphone port and power from a USB port:
http://kanexlive.com/products/item.aspx?id=3495
This one draws 2-channel stereo audio from a USB port:
http://kanexlive.com/products/item-id-3323.html
This is similar to the first one linked above, but less expensive:
http://www.cablematters.com/pc-56-26-mini-displayport-male-and-toslink-audiousb- male-to-hdmi-female-adapter.aspx
I don't know where you are located, but you should be able to find these adapters or similar ones somewhere near you, or at an online vendor who ships to your country.

Gx630 and problem with dvd playback via hdmi to plasma

I'm having problems playing a dvd from the gx630 while connected via HDMI to my plasma. Without fail, the screen freezes up within 5 minutes of watching the movie. I can watch a dvd on my laptop without a problem. Any suggestions?

For what it's worth, I experienced the same thing recently with my GX630 while connected to a 42-inch Sharp Aquos. I tried a couple of different discs, but all of them froze just as you described and I had to reboot. I read somewhere that you have to "turn off" the laptop screen when doing this because of dvd copying restrictions, but I haven't looked into it any further.

How do you read and display a signal from my a miccrontroller (MCB1700) onto labview connected via a CAN port on a PXI machine?
I tried using a DAQ Assistant but the CAN port is not included as one of the supported physical channels even though all its drivers are upto date.
Please help..
Thanks.

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:

Get the blue screen but the TV doesnt find the signal from my mac via hdmi

Before my mac could connect to my TV Samsungs LE32B350 without any problem, but now it just keep saying no signal from the tv. I get a blue screen when I connect the hdmi on the laptop for one sec then nothing happens. I have tried search for more screens but aint finding anything.
Please help me

Unfortunately older G4 minis are very touchy about certain hi-res monitors when run from DVI. Hi-res in this case means any monitor whose resolution causes the pixel clock to be above 135 MHz. It is normally the case that 1680 x 1050 timing will have a pixel clock above 135 MHz, although there is no way to observe that directly from within OS X.
There are only two known work-arounds for the issue. One is to run the monitor over a VGA interface. The other is to use a program like SwitchRes X to lower the pixel clock below 135 MHz. If you choose to do the latter, write back if you'd like some guidance on how to do that.

How to read a continuous temperature signal from a Pyrometer via RS-232

I'm trying to read and graph a continuous signal from a Pyrofiber Lab pyrometer which is coming in through an RS-232 cable. As far as I can tell there are no device drivers for this instrument (or any other pyrometers).
If I have the pyrometer take single measurements I can get those into LabView using the Instrument I/O Assistant, but only as an ABC string reading " 'emmisivity value' 'temperature' 'corrected temperature'" and not as individual numbers or data that I can use/graph. If I have the pyrometer in High Speed Transmit mode (which is the mode I need it in), I can't read the signal at all. How can I get LabView to continuously read (and record or graph) the incoming signal? And is there some way to parse the signal when it comes in as a string with " 'time' 'emissivity' 'temperature' 'corrected temperature'"?
I'm very new to LabView (and programming in general), so any hints on a good starting point would be appreciated.
Solved!
Go to Solution.

progers - There is not a specific solution, as there is not a device driver for this device (assuming you are also using a pyrometer).
There are serial communication examples in LabVIEW, by going to Help >> Find Examples >> Hardware Input and Output >> Serial.
You will need the programmer's manual for the device to know what serial commands to use to talk to the device (see Dennis's post above).

No signal apple tv3 to projector via hdmi to Dvi-d

I have a 3rd gen Apple TV. Works great on my 1080p tv, with optical out to my surround amp. When I connect to my Panasonic pt-ae500 720p projector via hdmi to dvi-d I get no signal at all. The projector is HDCP compliant and I can connect my ps3 to it at 720p no problem.
I have tried changing the edid settings on the projector, and changing resolutions on atv.
Any suggestions? I really need to set up my home cinema incorporating ATV
Thanks
Steve

It's an inherent problem between the ATV 2 & 3 and certain older models of TV / Projectors. Something to do with negotiating the signal between the two devices, the ATV falls over.
I also have this issue. I dug out my old PT-AE500 only to find that my ATV 2 was getting stuck on the Apple logo. No solution yet though, unfortunately.
There is another (old) thread on it here: https://discussions.apple.com/thread/2631562?start=0&tstart=0
There are a couple of ideas there, one of which was to switch the ATV on *before* plugging in the HDMI cable, let it boot up (give it 2 mins or so) then plug in the cable. This solved it for one person on that thread, but I can't get it to work here! I'll give it another try.
It's only the Apple Tv that has this issue as well. My MBP, Mac mini, etc, work perfectly. Just inconvenient having to lug them to the projector each time we want to watch a movie
Sorry I can't be of much help, but maybe have a read through that thread to see if any of the tips there work for you.
I'll also report back if I manage to find something that DOES work!

Extreme Base station can't extend signal from Mini desktop ?TCP/IP settings

I have a Mac Mini connected to DSL via a lynksys 8 port workgroup switch. I had 6 rooms in my house connected to the router by ethernet wiring. Worked great for several years. Now 2 rooms cabling seems to have gone bad (mice or squirrels, maybe). To avoid rewiring the connection outlets or pulling wire again (Ugh!), we bought an extreme base station. It transmits the internet signal fine when connected to the ethernet network (roaming), but I cannot get it to allow clients to access the internet in WDS mode.
The base station is in a central location where there is not an ethernet jack. It picks up the airport signal from the Mini (with extreme card and yes, I have the MAC address of the Mini chosen).
Internet connection is "shared" on the Mini and the laptops have no trouble accessing internet within close range of the Mini. The laptops can't access the internet through the base station. I suspect it's how the TCP/IP is assigned. I have tried every possible combination in the Airport Admin Utility.
In the WDS diagrams, it always shows 2 or more Base stations, never a Desktop and a Base. Are these incompatible?

...but can't figure out how for the Mini....
When you select "Share your Internet connection with AirPort-equipped computers," click AirPort Options to give your network a name and password.
Since they are the "same" network does it matter?
If one has no encryption or is using weaker encryption it will be the weak link for others to access your entire network.
Normally, if you want to seamlessly roam between the 2 wireless networks, ensure that they are using the same network name (SSID), same encryption type, same encryption level, and same encryption password. However any wireless device connecting to the Mac mini's network will be on a separate subnet.
Now I've got to figure out how to get files off the Office Desktop from the laptops, should I set up afp for airport or ethernet?
Enable Personal File Sharing on the Desktop.
