DisplayLink Forum - View Single Post - Mac Mini with USB Displaylink not extending properly

Hi,
I recently did a fresh install of High Sierra on my 2012 MAC mini. I have a VGA display connected via the Thunderbolt port and a VGA display connected by a USB3 displaylink adaptor. Before I had the display extended to the displaylink screen and everything worked fine.

Now the MAC boots in mirroring mode. Once signed in it briefly mirrors, then goes into extended mode. All works fine, but on reboot, or signing back in after the MAC has gone to sleep reverts to mirror, then extended. However all the windows that were on the displaylink screen move back to the primary display and have to be moved back.

Is this a known issue? Apologies if there is already a post with this issue. Please direct me to it!

Many Thanks
