my laptop display went out and I hooked up the monitor from my desktop.
This was working fine for a while. I rebooted to recently and for some
reason the disply settings changed. So I went into the display settings.
While trying to change the resolution back to where it was, I inadvertently
selected the multiple monitor setting and applied it. Now, nothing comes up
on the monitor. It appears to be off screen to the left, but since the
laptop display does not function, I cannot see any of this.
How can I change this back if all the windows screen pop up to the left
where i cannot see them?
