Second monitor is not detected by Windows 10

Microsoft Windows 10 (64-bit)

Yesterday I updated from Windows 7 to Windows 10.  Today I added a new second monitor but when I open the display settings only one monitor is being detected and both monitors display everything identically.  Please advise how to get Windows 10 to detect the second monitor.  This worked in Windows 7.

If Windows did not "see" the second monitor, it would be black with nothing showing on it.

 

You probably have your display settings configured to "mirror" -- which shows the same screen on both monitors.  Go back into the Display Settings and change them to "extend" -- which will have two different displays.

No, I have this setting set to "extend".

Six months agou it worked correctly: I boot my PC and login to windows. If I swithed my second monitor ON, my display settings detect it and worked in "extend" mode.

When I do it the same way now, it doesn't work.  Even if I enter Display Settings and try "mirror" or "extend" mode.

The only way how the second Display Port works is to switch my second monitor on before booting process started. 😞

Unbelievable....
