Duplicate screen option not working

[AlbanRampon]

Hi Jim,

You may not have a primary graphics card driver (Intel/Nvidia/AMD) which supports cloning across graphics adapters. This was only introduced as compulsory from WDDM 2.0.
So graphics on platforms like Intel 4th generation graphics don't do it and Intel won't be issuing new driver capability for these as they have now issued the 7th generation.

There are some workarounds but ultimately, this is the responsibility of the graphics vendor to implement the Windows standard to support this. http://support.displaylink.com/knowl...rticles/938634 shows how, by using the Windows inboxed driver it works. Of course, the Windows inbox driver complies with the Windows standard requirements.


I don't understand the second part of the report. If you right click on the desktop and select display settings, you should see all displays currently connected there.

Kind regards,
Alban
