I bought a separate mini display port adapter and hdmi cable from the apple store, for about $70. This cable is much cheaper and works Plug n Play just the same as the apple store. You don't need to install any driver in a MBP.
The old 2009 MBP can only send video out, so you will need a separate cable or speaker for audio out. I was warned in advance at the store since they tried to sell me another audio out cable. For now, I am happy with watching my [...] shows on my 32 inch vizio. I can live without surround sound. Mini DisplayPort Male to HDMI Male 32AWG Cable - 15ft
I bought this to use with my laptop, connected to my TV screen, so I could control the screen from the couch in my screening room. It was well priced and Mini DisplayPort Male to HDMI Male 32AWG Cable - 15ft arrived when promised. However, when I connected it from my laptop mini display port to the HDMI on the TV, I got a brief connection that then fluttered back and forth (on/off) and settled on no connection. I tried it on another TV set up and got the same results. IT DID NOT WORK.
This cord has a very unreliable and unstable connection. The screen on my macbook and on my tv both turn blue for about 5 seconds at least once every minute, and it is becoming even more frequent. Maybe I just have a defective cable, but I would never buy another one of these.
I bought this cable for my sister's 13.3" MacBook Air. I knew that the new generation of MacBook Pro's had the capability to output video + audio using a mini display-port to HDMI cable, but I was unsure if it could transfer audio on the MacBook Air. Upon receiving it, I can confirm that it does do video + audio on the new MacBook Air. When first connecting the cable to the mac and to the TV, I immediately get video but it is stretched. I had to change the settings to clone the display on the MacBook Air and on the TV. The audio was not selected to output to the TV by default. I had to go to System preferences, then to sound, then select audio output to TV/HDMI. The cable is just generic and there are probably better prices for the cable elsewhere but I was in a hurry and was able to take advantage of Amazon Prime to get the free 2-day shipping so it evens out in the end. 15ft is a perfect length and when rolled up is unobtrusive and packs easily if you travel. The Video and Audio is crystal clear and I had no problems with the connection being unreliable. Overall, it was a good purchase and I am pleased with the product.
I almost didn't purchase this cable because there were no clear reviews stating that it worked. This is the only cable that I've located which is mini DisplayPort to HDMI and is 15', at least in this ridiculously low price range. I need to supply these to engineers who travel with MacBook Pros. So I went ahead and ordered one to test it out to see... I wasn't expecting the audio to be transmitted over the cable, but to my surprise, it worked without any problems what so ever. I had the 2010 13" MacBook Pro hooked up via a 50' HDMI extension cable to our 65" 3D Vizio HDTV and everything worked perfectly. You do have to go into your sound settings and change the sound output to the TV device that it will have in the list of devices. The sound will normally be directed out your laptop speakers. All you have to do is go into the sound settings, click on output, and change to the TV your connected to and voila, your sound will come out your TV speakers.
So to recap... this cable works for both video and sound. At least on the 2010 and later MacBook Pros that send sound out the mini DisplayPort. For those of you who may not be aware, the 2009 and earlier I guess, MacBooks are not able to send sound out the Mini DisplayPort. I have one of these laptops as well and you have to either run a separate cable from the laptop headphone out jack or use a special adapter that will accomplish this for you. Here's a link to one of these Mini DisplayPort + Stereo (or USB) sound to HDMI devices: [...]
So if you were worried about buying this cable and wasting your money, don't sweat it. It seems to be one of the "real" ones that works as it's supposed to with both audio and sound. I don't know why it wouldn't work for everyone. I guess the TV involved and the HDMI cables could play a part...
Hope it works for you and hope you found this review helpful.
Cheers.
I used this cable to connect a 27 in iMac to a Dell HD monitor and the results were poor. There was a kind of "sparkling" effect on the video, and every 15 or 20 seconds the monitor went blank. I replaced this cable with a mini-display port to HDMI converter and an HDMI cable, and the monitor worked fine, so I am sure my problem was with the cable. It's a shame because the single cable solution is very neat.
Cord doesn't work with my macbook pro. Looked to see if anybody had the same problem online and there's no mention of this type of cord existing! Think it was too good to be true. Guess I'm going to spring for the 30 dollar adapter and dual link DVI cord...
My monitor recognizes it has an input when I use this cord, but still reads black. :('
