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.

My dual monitors shuts off and on again several times during the day. I've restarted my computer and docking station. I've cleaned and uninstalled the old DisplayLink driver and installed the new latest program. Problem is still not resolved.. Getting a bit frustrated. My Mac Pro M1 is starting to get a little old (from 2022) - is this a problem?
