Query: Overrated cable

I bought this cable because of the high reviews it received on amazon. I was going to use it to connect my laptop to my 24" lg lcd monitor. But at 1900x1200 this cable's image reproduction was far worse than the default cable I received with the monitor. There was a slight flickering to the images, and yes I double-checked to make sure the connections were secure.Also, in the image it shows that there is a ferrite core at each end of the cable. But there is only one ferrite core on one end of the cable that I received. This also makes it worse than the default monitor cable I received which has one on both ends.
