I use the cable on my Lenovo Thinkpad, which only has a DisplayPort output (and VGA, but that is nonsense) has. When starting up, there were two problems, but are at the driver of Levnovo, not the cord: The TV has the signal detected only after I have placed in the display settings, the resolution for the extended screen manually to 1920 x 1080 (1080p native resolution of most screens). The cable transmits no sound. According to various Thinkpad forums this is a driver issue that occurs about the Connexant cards - Who NVIDIA audio chip has, in which it could work. The cable itself is stuck, the picture is good and two meters are ok. The gold contacts are at a digital transmission anyway irrelevant. In any case, a good buy and a fair price.
