SUMMARY

Using a Thinkpad T14 Gen5 laptop with a Caldigit TS3 dock and 2x Dell 4k monitors, when waking from sleep I usually (not 100% though) need to remove dock entirely and/or power cycle monitors to get both displays working. When my primary display is not working, Plasma still sees it as connected and therefore doesn't move windows and the taskbar back to the working display, so they're just hidden. 

STEPS TO REPRODUCE
1. While connected to dock with lid shut, allow laptop to go to sleep.
2. Open lid of laptop, wake from sleep and unlock plasma
3. Shut lid of laptop

OBSERVED RESULT

One external display lights up correctly, the other remains dark. Monitor shows 'No Signal', however plasma believes it's connected. 

EXPECTED RESULT

Both monitors light up
