Once again, I learn the value of adaptability.
Working diligently on my laptop with two external monitors for a three-screen setup, the two external monitors froze with the image of whatever they were displaying. Since the cursor was on Display #2, for a moment it appeared that the computer froze.
After some research on the remaining active display, I learned that the problem was probably the docking station (Toshiba Dynadock).
One firmware update, one DisplayLink update, several reboots, lots of plugging and unplugging later, I am finally back up in running in triplicate! The last piece of the puzzle was to unplug the docking station to get those images out of the memory and off of the two external displays.
Previously, the biggest issue with the docking station was due to the fact that if it was plugged in at startup, Windows wouldn’t launch. This means unplugging it every time I turn the computer on. Since the update, I have been able to boot up with the docking station attached to the laptop so far. We’ll see if this continues.
Chalk up one hour of time not spent doing legal work and billing.
