View client's dual screen



  • Hi,

    I've followed the documentation to enable dual monitor support however I am still unable to view the clients second monitor, only the first monitor shows when trying to view the desktop, any suggestions?

    Is there a special combination of keys to press to switch to their second monitor?

    My admin machine only has a single monitor if that makes any difference?

    Thanks for any help.



  • Hi @fred123
    which operating system and which version of Veyon are you running? Did you enable dual monitor support client-side?



  • I've got the same problem. @tobydox
    The master pc is running windows 7 and the student pc windows 10.



  • I suspect there's an issue with the new desktop duplication engine. You can try to stop the service, remove ddengine.dll / ddengine64.dll and restart the computer. Are you able to see the second screen of this client afterwards?
