Despite some doubts I bought this cable to connect a Mac Mini with Mini DisplayPort to a 27 "monitor with a WQHD-resolution (2560 * 1440). In the Monitor unfortunately was just a DisplayPort to DisplayPort cable, a HDMI cable, a DVI cable and a Stone Age VGA cable here, so that a connection only worked via HDMI. The picture is only in HD (1920 * 1080), so that another cable was needed. Unfortunately, I was due to the many reports of bad cable highly uncertain which cable was the appropriate now and ultimately had a choice between this and a for more than 30 To so positive I was surprised that this cable works absolutely reliable and error-free. The full resolution was immediately recognized. For my part, therefore, a strong buy recommendation.
