Hi @francois,

Please make sure that you have the updated primary graphics adapter driver.
Desktop duplication on Windows 10 only works if your primary machine’s graphics adapter is updated and supports WDDM 2.0 – above.
To check, please run dxdiag.exe, go to the (primary) Display tab and check if the Driver Model is WDDM 2.0- above.

If graphics adapter is already updated and still has WDDM 1.3 – below driver model, then this is a Windows IddCx Display Driver limitation and there’s nothing we can do about.
