This item is 2 months old. It stopped working. We have tried different ports, different laptops, we have checked each and every connection multiple times. We have rebooted the laptops.
It worked fine for a few weeks. Then it started having “loose” connections in which the monitor showed pink or blue. Resetting the connection would fix the problem. Two days ago, the connection did not work, but plugging and unplugging all the connections finally got it going and it worked all day.
Yesterday, it would not work at all, no matter how many times each connection was tested. Once or twice, it would work long enough to flash on the monitor and then nothing more.
