I have an overlap at the bottom of the screen that is a copy of the first

monitor but there are useful things, namely the status bar, behind that
overlap.
Sounds like a typical hardware problem. The internal adjustment in your monitor
is probably called vertical phase. The monitor is failing to synch tightly to
the vertical synch pulses form the video card when the rate is pushed too high.
If you're lucky it's just an internal adjustment but it's more-often due to
change in value of a capacitor on the printed circuit board. I doubt that those
pixels are actually copies but if they are I'm all wrong. The video card would
have to be thoroughly messed up to send some pixels twice.
It's extremely rare for that kind of problem to originate in a video card.
