I used this cable in heavy use for a long year (I recently changed connectors). I have to say with hindsight I have doubts about its quality. In use, I had several problems of image jumping on my screen appearances also large green strips (it was really freaking me out). Today, I no longer use this cable and I do not have any problems. There are therefore two plausible assumptions: - The problems were well linked to the cable itself. - The problems came from the Display Port connector of my screen. When in doubt, I leave an extra star.
