Can't duplicate display, documentation and previous forum posts not helping
I know in documentation -> known issues, there is specifically already a brief explanation for why the Windows 11/10 Desktop Duplication (mirror) option is not available, but I’m still having a problem where I cannot duplicate my display on Windows 10 under Settings -> System-> Display. The Windows + P menu where it lets you select between extend and duplicate does not work either as I have 4 monitors hooked up to this desktop computer, so it just duplicates 2 of them and turns all the others off (including spacedesk on my android).
I checked that my WDDM is not less than 2.0 – it appears to be 2.7. Windows 10 has all its latest updates and so do my NVIDIA drivers for my 5070 TI graphics card. I think my CPU also has integrated graphics and in my BIOS that should be set to auto.
Under the spacedesk driver console everything looks good as well. I’m just not sure what to do. I’m including my dxdiag.txt file as well to try and get some help, but let me know if there’s anything else I should provide. I’m not sure if the diagnostic information collection from the driver console would help but I’m attaching that as well.

My apologies, one of my images has a minor mistake, but it might make it confusing – here’s the corrected image:

Can you try changing the resolution of your Viewer to either a resolution equal to your main monitor’s resolution or lower then check again if you can duplicate afterwards? Thank you.
Hello,
I have tried that and it still isn’t working. Here are all my exact settings just in case. Thank you
It also doesn’t work if I unplug one of my monitors – my GPU only has 4 ports so I thought that could potentially be the issue but I guess not.

Can you try clicking on “Clear Windows Display Settings” in the spacedesk Driver Console then try duplicating the spacedesk screen again? Thank you.
That sadly didn’t work either, but I really appreciate the suggestions
Hi @toss,
There must be something on your PC that’s causing this issue preventing you from duplicating to the spacedesk display.
We also saw in your logs that you have SuperDisplay installed in your PC. Can you try to duplicate your main screen to a SuperDisplay screen and let us know the result?
Can you also try if uninstalling SuperDisplay fixes your issue and let us know about the result?

Hello,
I actually installed spacedesk because I was disappointed that after paying $10 for SuperDisplay, it was having the same issues with not being able to duplicate. I did not think to check again after hitting the “Clear Windows Display Settings” button in spacedesk though, so that was a good suggestion – but unfortunately it still doesn’t allow me to duplicate.
I then uninstalled SuperDisplay and spacedesk still isn’t allowing me to duplicate.
Here’s an image proving it’s no longer installed, not sure what else would be helpful. Thanks again
Hi @toss,
Thanks for confirming this detail to us that in Superdisplay, the issue is also present.
Can you please do this below:
- Open command prompt and run “pnputil -e” then copy the output to Notepad and save as a text file.
- Compress text file as .zip or .rar then attach to your next reply.
Thank you.
