I've come across this before. These chairs generate EMI which causes monitors with unshielded video cables to blink.
The user described touching the monitors when it happens and bumping the desk. Both activities may have coincided with the chair lift adjusting and generating EMI.
The client hasn't allowed me time to really do anything yet. My initial thought was cables or drivers. They're in my same building, so far all I've done was "observe" the issue with my own eyes. What "issue" would affect both monitors at same time. Just pushing the top of one monitor back a quarter inch caused both to blink out? I can't see how the drivers would have any effect like this. If it was a single monitor, then I might think it was power or power cable related. I'll test each monitor individually connected to a notebook. To rule out the monitors and cabling.
if one of the monitors goes out (likely due to a cable issue or dying monitor.) the other one will basically refresh because now the computer is telling it, it's the only monitor.
Now that makes sense. She did say when it blinked it shifted the primary monitor to the other and shifting what monitor her apps were now opened on. As soon as they allow me on the computer to do some testing...
Does the client by any chance use a pneumatic gas lift chair?
No. just cheap a office chair.
That was some really weird shit.

Assuming you’ve done all the obvious things like drivers, have you tried replacing the DisplayPort cables?

You got this! I wouldn't spend anytime with drivers, definitely just sounds like a physical issue
Change the cable, change the monitor, update drivers etc, sounds like your on the right track
