Hello,
Every time i try to 'duplicate display' my main display just goes black and my second monitor now becomes my main, and only display.
I have been able to do this in the past, so thinking it might of been a Windows 10 update?
Any help would be much appreciated.
What kind of Graphics card do you have?
Do you have the latest drivers?
Are the monitors the same model and resolution?
Are you setting duplicate display in Nvidia app or in Windows.
Try Winkey+P.
I had the exact same issue. Although I was aware that my Windows 7 laptop (with Intel gpu and Nvidia 525m dual graphics) required you to use the Nvidia control panel to correctly clone the display I noticed that the option was completely omitted on the Nvidia control panel in Windows 10. By January I downgraded back to Windows 7 where everything works as it should.
Does anyone know of a solution to this? I wouldn't mind completing the move to Windows 10 at some point. Right now though I'm quite happy with Windows 7 - old reliable!
