    Wow . . . . this appears to be the EXACT thing i’ve been looking for. Can’t wait to get home and see if it works for me.

    If it does – thank you very, very much! If it doesn’t, then how DARE you waste my time and get my hopes up?!?!?!?!?

    It worked! Thank you . . . .

    Only problem is that the sound will no longer come through my tv!

    • Mayur says:

      @Shane The reason for sound not coming may be coz of an unsupported MacBook model. Read the Note to know which models support sound output via HDMI.

        If we are working with an older MacBook model that doesn’t support sound output via HDMI is there anything different we can do to make it work? Thanks so much for the help thus far!

It worked for a minute but i assume i did something wrong that now when my tv is connected to the mac, the tv is blue and green and the mac only shows the homescreen. anyone can help me wiht this situation?

    Awesome can’t wait to try it when the lead finally comes. Just one question. Is there a way of saving the profile etc so u don’t have to go through the same routine each time u connect the cable to the tv etc?

    Thank you very much! I had the same problem and now, thanks to your article, everything works perfectly. But I’m still wondering, why it doesn’t work like it should, just simple through the possibility mirror displays, which could be much more easier and usefull. Especially when you’re controlling external display using MacBook only. What can we do… Once again, thank you very much!

    Thank you so much! I was frustrated mirroring doesn’t allow fullscreen on the external monitor (TV) and also messes up with screen sharing. I have suffered for over a week with this issue but glad I didn’t give up and found this site. Switching mirroring off and moving the menu bar to the external monitor solves both problems.
    My Vizio TV has a channel with video-only HDMI and an audio input so I do not have audio problems.

    My MBP 2011 running 10.6.7 wont recognise Samsung Smart TV via thunderbolt adaptor and HDMI cable. The external monitor is clearly ‘seen’ as when connected the MBP screen dims briefly, but the Samsung just says no signal detected or similar.

  10. What Haveyou says:

    The problem is that there’s a major bug in OS X (as of Lion): No audio is sent to the TV unless “Mirror Displays” is on. This makes it impossible to watch movies full-screen, because you won’t get any audio.

    the arrangement tab doesnt show up on mine. it was just working now it doesnt work

    My connection was working fine until one day it just stopped working. Now I get the infamous message: “Unsupported Signal. Please check the device output.” The laptop recognizes the other source and I can gather windows in my Display preferences but the TV is not supporting the signal. WTF?!?!?

    thank you mayur for the tutorial. I tried the same with samsung smart tv and it worked like a charm.
    Only issue i faced is the menu bar just moved away from the screen top which is not visible in my tv. Adjusting the “Undersan” under “Display” brought back the menu bar visible in the tv.

    Hello. Thank you kindly for your help. I have an issue however, I can only use 720p or 1080i and the 1080i does not look good, there\’s a lot of like pixel noise. If I use the 1080p it will come on the TV for a second with some weird flashing pixelated noise then go away. Also, I my laptop Macbook Pro 2011 supports hdmi out for audio but only the internal speakers will work. I\’m using an adapter for thunderbolt to hdmi, could this be the problem?

    • Leo says:

      OK…SO WEIRD. Out of the blue I was going over the steps from the beginning again while I was in 720p and decided to try the 1080p setting and hey presto it worked. I have NO idea why it worked that particular time and not the other 12 times I tried. I\’m confused. I\’m thinking maybe there\’s something about the order in which you do things? In any case, the audio still wont work from the hdmi. Also, I have an Apple TV and while I was writing this I was trying to see if I could use the Apple TV as the audio out and as soon as I plugged the power into it and the cord from my receiver the 1080p stopped working as it did in the previous post. WTF? Is the apple tv and my macbook communicating as soon as I plug the power in to the apple TV? Can I change this? I\’m not too concerned about the audio because I just used the headphone port to my receiver, but it would be nice if it would work with the HDMI cable. Strange things are afoot.

    When i connect the cable, macbook detects the external display and seems Everything is working perfect on the macbook as mentioned however screen still shows \”No Signal\” all the time. I did check with input source as HDMI and tried tweaking with every possible thing but display not coming on the screen. what could be the possible reason for the same?
