That solves a lifelong mystery for me. I have twice had monitors that blink off right when I shift position or get up from my desk. I can tell it's caused by me moving, but I can never reproduce it. When it first started happening, I would aggressively shake the monitor cables and nothing happened. But I never considered that it could be my chair.
