I have a coworker that has two monitors on a free-moving desk stand and he has monitors as far apart as possible. The monitors are pretty small (24") and there is over two monitor widths between them. He has to whip his head around like he is trying trying to dodge a fly all day to do his work.
He complains about back and neck pain all the time.
Oh, I wasn’t thinking at all. It was a mistake my body won’t let me make again though.
