Office chairs are turning monitors on and off.
This is actually officially documented on the DisplayLink website as well: https://support.displaylink.com/knowledgebase/articles/73861...
This has been happening to me and I had no idea it was this. Every time I sit down at my chair the monitor goes black for a second. Never would I have guessed this.
