    Does this cable provide audio?
    A shopper on Aug 26, 2017
    BEST ANSWER: Yes. I'm using this to stream movies to a tv via an HDMI cable. Audio works great.
    Will this allow me to use 2560x1080 @ 60HZ when connecting a Macbook to an ultrawide monitor?

    Fantastic Mini DisplayPort to HDMI adapter
    Purchased this adapter to use with a 2015 MacBook Air, so that I could connect it to my home theater receiver via HDMI. This adapter works perfectly - the Mac outputs full 1080p video at 60Hz, as well as multichannel surround sound audio (I have a 5.1 system). Note for Mac users: you may need to open the Audio MIDI Setup application to configure how your Mac outputs the sound/audio, so that the channels correctly map to each speaker.

    PROS: - Great quality
    - Simple plug & play
    - Great price

    CONS: - None!

    Great device at a low price.
    Upon receiving my first adapter, it only worked for 10 seconds, then oddly enough, it stopped working. Monoprice sent me a replacement no fuss, and the second adapter has worked just fine, in fact I'm using it right now with my Surface Pro 4 with a 1440p DELL monitor.

    There are a couple of things to note, and a few issues, that seem to stem from Windows 10's poor software.
    The Surface Pro 4 is a 3:2 ratio monitor, while your screen will likely be 16:9, when using "duplicate this display" this mean black borders on the sides of your screen. It will also display at over 1080p resolution if your TV or monitor supports 1440p or higher.

    When trying to display "second screen only" on a 1440p monitor (with the Surface Pro 4 screen turned off), it can be a little bit fiddly to deal with. Sometimes it won't work, but after a few attempts I got it to work, and it will display a full 16:9 with no black borders.

    If your monitor doesn't have speakers and you lose audio (since Windows 10 may try to send audio through the HDMI cable to the monitor) to have audio play through the Surface Pro 4 speakers, go to Control Panel - Hardware and Sound - Sound and click on the Speakers option to regain your audio.

    Overall I am satisfied with my adapter.

    PROS: Low price.
    Monoprice customer service was helpful.

    CONS: None.

    Good, small size

    Works great for 4K
    We purchased this cable to connect Microsoft Surface Pro 3s and 4s to 4K displays. There's not much more to say: it worked flawlessly.

    Nice little adaptor
    I use this on my Mac. It works great and is very slim. Since the Thunderbolt/display ports are so close together on my Mac this was a great way to connect two monitors without taking up much room.

    perfect fit
    Ordered and promptly received the patch cable I needed to connect my new Apple Computer to a HDMI so I can stream my computer films on my television. Product was exactly as described and worked perfectly. And, I might ad, at a cost far less than had I gone to Apple.

    Works Great
    Works Great. Haven't had any video problems with Macs and Surfaces. Only downside is more computers are using USB-C.
