Best way to disconnect / connect with v4.3 beta 5/6

[smithgcovert2]

I am using Mac OS 10.13.6, with v4.3 beta 5 driver version.

I'm lucky - the airplay solution works good enough for me. Its the resolution I need, with the landscape I need, and I only have 1 monitor. The old drivers on 10.13.2 worked much better, but, eh, I don't want to relitigate that here.

What I do want is to learn to live with this driver "better". And I have an issue now I can't figure out:

I can boot my machine, and attach the monitor via DL adapter, and it all works. However, if I disconnect the USB adapter, I can not get the monitor to work again until I reboot.

I would like to be able to restart the monitor in "separate display" mode upon reconnecting the adapter. Has anyone found the most successful way to do this? I am totally willing to do something (command line / UI) before I disconnect, before/after I reconnect -- but have no idea what I should be doing.

Any process or procedure would be preferable to rebooting my machine each time I want to use the monitor.

Thanks,
Greg
