I have been working with 2 screens for a while (Windows 8), as an extended desktop. Everything has been working fine, moving a window or the curser from one screen to the other is no problem.
Today I had to do a reboot and after the reboot both screens are active, but the second screen only shows the taskbar and a blank screen. I can't move the cursor to it - it just bumps up against the edge of the first display and won't move over. Likewise, if I slide a window across it doesn't go onto the second display.
How to I get it back to normal use?

Ok, I found the answer myself, which I will post for anyone with the same problem. Turns out after the reboot the system didn't recognize the physical positions of the monitors. To fix, which was by accident testing things out, I did the following:
Right click a blank area on the desktop and select Screen Resolution. A picture of the two displays comes up.
Click Identify. Large numerals appear on the monitors and that's when I realised they were switched back to front - the monitor that is actually on the right appeared on the left in this layout.
Drag the picture of the monitor that's in the wrong location into the right location and click Apply.
Problem solved.
