Dual monitor one monitor random on & off

Currently one monitor randomly off, need start the Display Link software and click the monitor icon to turn on it again. I am using macOS Tahoe 26.2. Please advise. Thank you.

Both monitors (HP E223) have blinked off and on at least 5 times within the last 15 minutes.

Restarting my MacBook Pro seems to have stabilized it. I did the same thing yesterday when the random off/on happened and it seemed to have solved the problem. But then I had to take a meeting in another room and when I reconnected my laptop to the dock, the off/on issue was back.
