I have two monitors that are usually set up as a dual display. If I boot with only one display, I get the same kind of problem with each display. If I boot with two monitors, then the second monitor will display correctly and show the windows desktop. I can right click on the desktop on the second display to get display properties where I would change the resolution, but the window opens on the first display, so I cannot get to it. When I press F8 while booting, nothing is displayed on the second monitor.
I haven't made any changes to the computer, but I am suspicious that the 16-year-old boy staying with us may have done something and will not admit it.
I don't see any way to do anything besides blindly fishing for the display properties window on the blank first display and dragging it over to the second display.
I was able to grab the display properties window blindly and drag it to the second screen (actually not that hard). There is nothing wrong with the resolution and refresh rate settings in the display properties window. I changed the second monitor to be the primary display, but when I reboot, it is back to the secondary display. So no progress.
