probably because there is no audio output through the mini display port. the hdmi connection in this case is only transmitting video. you may need to do a separate audio connection from your audio jack.
I also couldn't get it to work at first, but I figured it out. Go under audio and select HDMI. It should work then. If it doesn't work stop the movie, and select HDMI before you play the movie, then start the movie and it should work. At least thats what worked for me on my mac. Hope this helps.
This adapter won't work for audio, it is strictly for video only. If you want one that has both video and audio together, check out monoprice.com for that specific cable adapter
Go to System Preferences then select "Displays" under Hardware. Select "Arrangement" then check the box for "Mirror Displays" just under the window. I have a MacBook Pro and that's how I got to see the computer screen on the TV. Hope it helps.
Make sure your Mac detects your TV. It sometimes takes time for it to recognize it or change to another HDMI connection. I had the same problem and then I connected to another HDMI. Not sure why that worked but it did. Also make sure you Mac make allows for audio stream through HDMI. Check internet and youtube for this.
HOW CAN GET MORE THAN JUST THE DESKTOP DISPLAY ON MY 32" BRAVIA. NOTHING I'M DOING ON THE 13" MBP SHOWS IN THE OUTPUT. MINI DISPLAYPORT TO HDMI TO HDMI INPUT ON THE TV. PLEASE HELP ME SOLVE THIS ISSUE. THANKS
check your "display" settings in your "system preferences" after hooking up and turning on the monitor. you should be able to control the output at that time.
I can use this product to connect my new Macbook Pro to a couple of TVs in my home but it just does not seem to want to work with my Mitsubishi 65" rear projections screen TV (which is HDMI compatible). I have tried different HDMI cords, different ports on the TV that work with other products but nothing seems to get the Macbook to recognize the TV. Any ideas?
After 4 hours of talking to tech support, I answered my own question by ordering the cable from Apple. IT works like a gem and all problems are resolved.
I can't say for certain whether this will work, but try using a mini-to-VGA connection from your Mac laptop to your TV. For me, one TV "reads" the Mac signal as analog (VGA) and another TV "reads" the Mac signal as HDMI.
Check to see if your MacBook Pro 7" year and make have audio and video through the mini-display port. I believe you can check on the internet at (http://support.apple.com/kb/HT4241) I have a 2011 iMac Desktop and it works great with my Plasma HDTV. Lots of free content on the Internet that is viewable on HDTV.
Sounds like the Adapter Shorted Out. This can happen for a number of reasons that all don't have to do with the Manufacturer. Regardless, I'd Exchange it.
