Some people in here have talked about how they are having display issues. With all this new information about the reality of these cables, I think more people should be concerned about the quality of their cables.
A cable can either make, or break, your computer experience, so it does matter. So what is the lesson, check those cables. Its cheap enough to try another cable. Most of us won't be spending 1000 dollars on cables though, will leave that up to the multi-millionaire Linus. lol.
