Useful for marguerita lovers who need to multitask...

About your monitor, I suspect what the earthquake might have done is
flex some bit of hardware just right and cause it to rub through some
micro-corrosion on an internal signal lead. You know, the same mechanism
attributed to those "reseated connector" miracle repairs? I've seen some
odd hardware behavior changes when a system is taken apart, moved, and
reassembled. You wouldn't expect it to happen, but every once in a while
it definitely DOES happen.
