Cable is not VESA compliant. Hence, you will have issues with waking up your connected display when resuming your computer from a soft (screen only off) or hard (low power state) sleep. Pin 20 is connected. Hence, both the display and computer try to provide 3.3V on pin 20. This causes link negotiation issues, which leads to the aforementioned inability to "wake" the connected display. Tested on 2 different displays and 2 different computers with mini display ports, for a total of 4 configurations that all showed that the cable is at fault.
While I was able to get the normal and very good resolution of HDMI adapter/cords (1900) and okay but higher resolution with VGA (2048 x 1280), this ten buck cord did the trick. It caused a great deal of flickering of the screen until I enabled MIRRORING and made sure that Overscan was off. At first the cord and the monitor and my laptop were, shall we say, in negotiations on what resolution would be provided. Staying in the system preferences, display boxes, clicking and un-clicking mirroring, I was able to get the maximum resolution of the monitor which is 2540 x1600. I tried the Apple Minidisplay port to dual-link display port adapter and that was a waste of time and it will be returned shortly. The resolution it gave was around 1600x but it looked horrible, made the monitor appear as one of the original and huge CRT monitors from the 80s. I highly recommend this cord, nice gold plated connections and I will likely buy another.

I bought this cable to use with my new 13" MacBook Pro, connecting with a new Dell 30 inch monitor, U3011. The monitor kept falling into sleep mode and I had continual issues, which I thought were a compatibility problem between my new Macbook Pro and the monitor. I then found this mini display port adapter cable from another manufacturer and since installing it I have had zero issues in regards to performance and compatibility between my MacBook Pro and my new Dell monitor. This Star Tech cable has some serious compatibility and intermittent problems when being used with the new MacBook Pro connecting to Dell monitor U3011.I purchased my replacement cable from circuit assembly and I am now running 100% error-free.Cable worked out of the box, simply and with no drama. I use it to connect an incredible Microcenter Auria WQHD (2560x1440) resolution $400 monitor to my 2012 iMac 27", using the displayport/thunderbolt port on back of iMac. The cable is a great value and worked w/o any problems. Could not be more happier with value and performance.

Well, what else can you really say for a review of a cable? The price is right and it functions perfectly.My motivation for writing a review is for a niche group of consumers who may which to know this tidbit of information -I'm using this to connect my work laptop, a PC, to my home display -a 27" Apple iMac. The iMac doubles as an external display with an HDPC-compliant source, and I can confirm that this cable works just fine in this configuration for both video and audio.
