Windows 10: Duplicate Display Issues

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.

:)

 

Windows 10 2nd monitor resolution zoomed in

1. you replied to my solution with a solution that was not my problem. 2. my issue was both extended and duplicate being zoomed in, "Blurrier" on second display than first. 3. fixed it by making sure both displays where set up for the same resolution.

Thank you.

 

Surface Pro 2 Graphics adapter issue after Win 10 upgrade

while you used the word "extend" are you trying to duplicate or extend? what' I've heard officially is

"The Windows Graphics team is currently investigating potential solutions to the Duplicate display mode issue. Alternatives are to use the Extend or Second Screen display modes which can be set via the Project UI (Windows key + P) or the Settings/System/Display
dialog."

 

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!
