More information:
After about a week, of working there is clearly an problem in the driver. On two different machines, with different cables etc, the monitor will loose display connectivity and display un-synch'ed video (static). If it fairly reliable to trigger this by changing the monitor settings in Windows. For example
Stage 1) Have Desktop showing on laptop and external screen
Stage 2) Plug in UM740 - Desktop appears across all monitors
Stage 3) Disable display on laptop screen - Display turns off on laptop screen fine, but UM-740 display borked.
Stage 4) Unplug UM-740 and re-insert to no avail. Screen still borked.
(Borked not a great technical term, will take some photos).
My LG206WU is rock solid, but I do not connect/disconnect this.
