Ok, maybe I missed something here but if it is one of your managers doing the "visiting", why would it matter if he/she saw your monitor? I know its annoying, but if you work for them, aren't they entitled to see what you're working on?
Other than removing the chair completely, I'd vote for either rearranging the cubicle so the chair doesn't face the monitor or moving the monitor so it isn't seen from the chair. Another suggestion is one of those things that act like blinders on the monitor so you can't see what's on it unless you're directly in front of it. My boss has one on his and even though his visitor's chair is at an angle to his monitor, I can't see what he's looking at unless I stand beside him.
I guess I'm lucky that I have an office with enough space that I was able to arrange it so that no one can see my monitor without walking around my desk (gives me enough time to reduce screens if needed) and my visitor's chair is on the opposite side of my desk completely.
