Hi Guys,

I upgraded to Mac OSX 13.2.1 Ventura last night, and my plugable UD-3900PDZ dock stopped working with one of the two external monitors.

I had to unplug HDMI 1 monitor, and plug HDMI monitor 2 into the number 1 port first, then plug the original HDMI1 monitor into port 2 in this sequence to work. I don't know why but this is how I managed to get it working. If I tried this new setup without this sequence it would only work with one monitor.

Hopefully, this helps someone that has issues displaying both external monitors.
