this solution got output to my 2 DisplayLink driven external monitors, but required some extra work in the system preferences.
reboot broke it all again

Steps:
1. uninstalled DisplayLink driver
2. rebooted and checked the kextcache to verify it was cleared and verified DisplayLink software no longer installed
3. reinstalled DisplayLink driver v5.2(15)
4. rebooted

Results: 2 external DisplayLink monitors are recognized by the OS (cursor displays on each) but only shows black screen. app windows moved to the monitors do not display, nor does the desktop background image

5. Opened System/Preferences/Displays
Selected: Arrangement Mirror Displays
all external monitors display everything perfectly
deselecting 'mirror...' and the DL monitors go back to black, but clicking on each monitor in the arrangement display shows the thin red line indicating another monitor adjacent to the main display
Selected each of the external monitors in turn and selected "Optimize for display"
Unselected 'Mirror Displays" and all are working as expected

6. Rebooting computer - external DisplayLink monitors return to black w/ cursor state.

any other thoughts or suggestions welcome ... I'll try anything at this point. this is my work computer.

Thanks, All!

Same here !
We still wait for a working solution Displaylink !
