Two monitors and one system. Three user accounts, the pc owner, me, and a guest.

I arrrive at the location for a few days. Two monitors, an Apple and a HP.
My user account had my own desktop from a previous visit. The only thing on my desktop was Google Chrome and Firefox.
When I arrived, there was a May and June calendar was seen on the HP monitor. The pc owner's account. The main monitor, the Apple had my desktop and it's two browser icons.
I wanted to use FF and IE. Start > Internet Explorer got me that browser.
Firefox was used too and on my use account, I'd have both browsers open.
I discovered that if I used my cursor to drag one of my browsers far enough left, the left portion would be seen on the HP monitor. I could, as an example, have half of the webpage on the HP monitor and the right half on the Apple monitor. Also, without dragging the webpages, I could move the cursor to the left and it would be seen on the HP monitor.
How did the pc owner have this setup so this was all possible?
Then the pc owner who was out of town and had access to his account on this same pc, wanted to adjust the screen resolution on his end for some reason, maybe on his laptop or other internet connected device.
After that my desktop was no longer on the Apple monitor but on the HP monitor.
No problems except:
When I opened FF, that browser opened on the Apple monitor and was very high resolution, very large.
The desktop on the HP monitor was normal size. When Chrome was opened it did so on the HP monitor. So, now even though the two browser icons were on the HP monitor desktop, FF would open on the Apple monitor and be very large and Chrome would open on the HP monitor.
I also tried to access the FF browser using my cursor. Once I moved the curser to the right to cause it to go to the Apple monitor where the FF browser was open, I could not move the cursor back to the HP monitor. I was stuck. The monotir with the proper resolution was the HP, but my cursor was stuck on the Apple monitor.
I had to re-boot, and abandon FF and just use the Chrome browser because the resolution was way to high for FF and FF would open on the other monitor as well as the fact that the cursor could no longer go back and forth between the two monitors.
How was all this setup by the pc owner and why did the attempt to adjust the resolution cause Chrome to open on one monitor but FF (from the same desktop location as the FF icon) would open on the Apple monitor?
