Reluctantly, I walked over to this persons desk. He told me his display was wavey/off color, and it happens when and is resolved by, stomping his foot. "Here, I'll show you." He then, I crap you not, proceeded to slam his foot onto the floor, much like he was crushing a cockroach.
"See, look what its doing!" Sure enough, the monitor began to change colors. When he was done, I calmly asked him:
"Sir, have you tried NOT stomping your foot?"
I have not heard from him since.
