i bought a new plasma panasonic tv one month ago and i have the adapter and everything.... i've also watched already over 30 movies by connecting my laptop with the tv through the adapter and hdmi cable... yesterday i was at a friends place and i connected my adapter to his hdmi cable and my mac detected his tv straight away but it didn't work . after this my friend told that he faced a problem with the hdmi cable(brand=hama) and he could not connect his laptop . after finding his tv and finally not working today i connect it to my own tv and the screen turns blue for a couple of seconds like trying to connect but does not detect my tv ... anybody has any idea what happened. my mini dvi port seems to work because the moment i connect the cable it turns blue( as when i was watching movies no problem)... now what happened ??

    my MacBook Pro isn't able to detect my monitor (using Apple DVI adapter) samsung syncmaster 215TW ... the adapter is ok, they have tried it in service. What should I do? I have tried resetting PRAM, installed new firmware, tried another adapter.

    I m not going to buy new external monitor because of apple. I'm desperate and i know there is a lot of people complaining about this problem and Apple is doing anything with it!

    Worked until recent update flawlessly, now won't detect display through HDMI.

    I exactly have the same problem! i´ve searched the issue around on the internet and it seems like people have this problem after the update.

    please fix it apple!

    Same issue. Mine has worked flawlessly for a year, and all of the sudden my monitor is not recognized. This is not a small issue as I have trouble coding without my external monitor. I can connect it to other monitors without fail, but my home monitor does not work. FIX THIS APPLE.

    same issue here. C'mon. this really *****. 1500 for a laptop and you can't use the HDMI to lcd's.... whats the point???

    Similar for me as Giannisg - sony bravia TV working flawlessly for months as external display using mini displayport to HDMI.

    Then in January I brought MBP to a friend's house and successfully connected it to her TV and we watched a movie. Then brought it home and lo and behold it suddenly will just NOT detect my original set up of Sony Bravia display...

    not sure if this new problem is due to the OS update or the fact that it was used with another display...

    I am going to change to a different adapter today though it really annoys me to have to buy a new one when I am presuming my original cable is fine

    Anyone had a resolution on this yet as i have the problem also? My MAC wont find the TV after months of working just fine.
  • Koi_Girl Level 1 (0 points)
    oh grrr! my other half went to an apple reseller earlier today to get me the new adaptor and was sold the wrong would think an apple reseller would know the difference between HDMI and DVI - they look pretty different

    now we will have to return this one. TBH I don't think changing to a different adaptor/cable is going to work - it is a fault with the OS

    I will jump on the bandwagon here.
    My Macbook Pro is only a few months old, as well as my Sony Bravia, hdmi cord, and adapter.

    All was working well until last week. The tv gives me the message of "no signal". I tried to "detect display" again in my prefs, but when I click on that option, nothing happens. Nor do I have the option any longer to select "Sony TV" in either the display tab or the sound prefs.

    Absolutely nothing has changed in my setup, and this has become a frustrating issue. Any more news on this problem?

    I have been searching and waiting for an answer to this problem for about a month now and have not found an answer. I think it is a glitch in the 10.6.6 update. This is very frustrating since I stream movies from my MBP to my TV. FIGURE IT OUT APPLE ***?!?
  • TheMadcapLaughs Level 1 (0 points)
    so... seems i'm not the only one.
    Yesterday i switch on my MBP (bought 4 months ago...) and connect my tv using mini display and hdmi cable.
    MBP monitor blinks for a second and nothing happen. On my Toshiba (really cheap TV but it worked for months...) blu screen and No Signal Video.
    I've tried also reinstalling OS... nothing!
    Does anyone of you solved? changing adapter solved the issue? any answer from apple?

  • SHDWBX Level 1 (0 points)
    Same same here... exhausted all the suggestions I've come across. My external monitor ( via mini-dvi port) just stopped working after a couple years of being problem free and now I'm just getting the brief blue flash.... it started around the time of the 10.6.6 update. APPLE Please sort this out... the alarms a'sounding on this issue
  • BrentR01 Level 1 (0 points)
    I have had this same problem with my MBP. The only solution i have found is a little annoying but works flawless for me every time.

    Restart your computer with the cable attached to both the computer, and the TV. Make sure the right input is selected before restart.

    Should detect the display right away once you log in.

    hope that helps!
