I just got back from the apple store. They said the problem is the logic board and it needs to be replaced. The genius didnt really seem all that competent. Can this really be the problem? I have a 2011 MBP with 10.8.2. I have tried different cables and monitors. I also tried it with ubuntu and no luck. When I connect the mini display cable to the cpu nothing happens at all. No blank or blue screen handshake. GTFX or pram reset didnt work.
Any ideas out there? I am losing my faith in apple for the moment.
When I went to see the apple guys they said the same thing. I declined to have my logic board replaced because I didn't think that was the problem. I tried a better adaptor and it's worked perfectly since.
Having said that, I was getting a connection, it just was full of static or flashes of screen but completely unusable. Since you don't have any connection it may very well be that for you!
folks - it definitely ISN'T the logic board.. but, why not tell them that they can go ahead and replace it and, if they show you it working afterwards, AND ARE WILLING TO GIVE YOU A ONE YEAR PARTS AND LABOUR WARRANTY (which is certainly quite reasonable for the amount they're gonna want to charge you for it...) then why not go for it..
but I don't think they'll do it because they KNOW that a logic board would cause many other probs before this one silly fault.
I am not saying that the universal problem is a logic board issue. The most common problem seeming to be a mdp/hdmi compatibility issue and fast burnout of adaptors.
But the problem for maltmandan seems a logic board issue as he seems to have tried all the solutions we suggested. I had my mbp replaced for a logic board issue and had cable issue with the new one.
so if the solutions listed here dont work, then probably its a logic board issue.
@maltmandan normally logic board issues tend to heat up the mbp a lot. so if ur machine is overheating then you can almost be sure.
"so if the solutions listed here dont work, then probably its a logic board issue."
or, perhaps, it's not a solvable problem...that has nothing to do with the logic boards since the Non-thunderbolt system seems to work fine with HDMI and, if you read back, you'll find that for many of us, it all worked just fine - in my own case for over a year - and then SUDDENLY stopped... without any other "bad logic board" symptoms (not exactly a "fast burn out of adaptors").
You'll also find that people have tried it with NEW machines.. and that logic board problems are not generally THIS specific to the one function.
But, as I said, to each his own - try it and see if it works.. but I sure as **** wouldn't fork out the cash without the guarantee that it WILL fix the issue and that it won't simply re-occur.
i was having the same problem tonight with a:
- Samsung Smart TV UN46ES6580F
- Macbook Pro 13" mid-2010, 4GB ram
- PPA branded MDP to HDMI cable from @ $19.99 from Fry's
- display mirroring
- match desktop size to Samsung TV
- screen would flicker blue when MDP to HDMI was plugged in
- MBP would recognise the TV (was listed as Samsung up in the DISPLAY icon of top menu bar)
- TV would recognise the MBP (HDMI was a SOURCE option only when the cable was plugged in)
- MPB had screen, TV was black with error message
- go into PREFERENCES
- select DISPLAY and look at RESOLUTION window
- select 1080i rather than 1080p
PS needed to manually force the audio output in AUDIO-MIDI to HDMI to get the sound out to the TV
PPS some occasional audio errors (no sound for 2-3 seconds) with flash based internet video but clearing FF cache helped a bit (FF 18.0.2, Flash 11.6.602.167)
Hey guys. I thought i was having a problem when connecting my iMac to my TV (42" LG LCD). Turns out i didn't realize that my TV was just a 2nd monitor, not a mirror of my Mac. I'm using a Belkin Mini DisplayPort HDMI cable. I was able to adjust the resolution on my monitor to 1080p so now everything is much clearer. My only beef is that i haven't figured out how to get the audio through my TV or receiver.
Any help at all would be greatly appreciated. This setup plus XBMC will be amazing!
Go to settings - sound - output - it show show your hdmi device as an option. select it. your sound should work now. If teh HDMI device does not show up then probably your mbp does not support sound through hdmi (pre 2011 models).
Only glitch here is you would not have volume control for HDMI device. It will always be sex to max. Solution is to install sunflowerbed (freeware) and settings - sound - output -sunflower 2 ch. Click on sunflower icon on top bar and select HDMI.
PS: Regarding you not mirroring your display is not exactly the problem being discussed here.
So I have an issue..my macbook pro won't allow me to even see the arrangement tab when i try to detect displays. This is the error message that popped up, "The Arrangement tab of Displays preferences is hidden because you only have a single display attached to this computer." I don't know how to get my mac to recognize any additional displays. I have an Mini display port to HDMI connector and set it to my tv, it flashes blue once and nothing happens to the tv or my mac. Under displays I don't see any option to mirror anything, nor any addional tabs that i've seen on multiple youtube videos or tried to find answers on various forums. Has anyone had any similar issues? Please help
@Sassy most people who posted on this thread had the same problem. And we have a had moderate success in resolving the issue. Read my post on page 41 (last post) to see a summary of various solutions which may or may not work.
Probably you will have to change your mdp to hdmi adaptor and get a mdp male to hdmi male single cable.
Try and let us know
@aarjee: Your following suggestion on page 46 worked for me with MacBook Pro (2010 - Snow Leopard). Downloaded Gfx card status and after selecting 'nvidia' GPU I got display on my Samsung Monitor.
I should also mention that it worked with $5 dvi-hdmi adapter. Thanks again.
- Intel based macbooks have too GPUs. One a board based Intel GPU for light work and a third party GPU (like NVIDIA) for the most graphic intensive operations. The switching between this is automatic and should happen by itself when you connect an external monitor/tv. However it seems that this fails to happen in some cases. Gfx Card status is third party software than can be installed into macbook and lets you control the switching process. Some users seems to have success in connecting a external monitor when you set the macbook to use only the third party gpu but changing setting in gfx card status to discrete.
