Even though the cord quality is good, this wire didn't work out for me. I have a monitor that runs 1080p @ 144Hz with variable refresh rate. Despite the wire claiming to run 4K @ 144Hz, it fails to run for more than 30 mins on my 1080p @ 144Hz before overheating. I have to constantly unplug and re-plug it into my laptop to continue using my external monitor. I wouldn't recommend it to anyone who wants to use it for G-SYNC (or FreeSync) at 120Hz or 144Hz at all. It is probably okay for a fixed, 60Hz usage.
