I have an Acer 27 inch monitor connected with 2560 * 1440 resolution on a Geforce GTX770 graphics card. The cable is functioning properly and has a good picture quality. In my view, it is a little better than when the monitor is connected via a dual DVI cable of the same length.
The connectors are gold plated and have a lock. Overall, they build a little shorter than a DVI cable so that my computer 1cm continue to slip backwards.
