I'm looking for a virtual display driver similar to the one included in ZoneOS ZoneScreen that does not have the limitations of WDDM so that it can be used in Windows 7 of Windows Vista.

All I need is something to emulate a display adapter and a monitor so it shows up in the display properties. I then intend to use a VNC server with the display device set to that virtual display, and I can then use any VNC client as an additional monitor.

ZoneScreen works great in Windows XP for this exact purpose. It won't work in Vista/Win7 for the following reason:

Windows Vista and Windows 7 Limitations

These operating systems have two important limitations affecting ZoneScreen display driver. First, due to Windows Display Driver Model (WDDM) architecture, ZoneScreen virtual display driver can't run unless legacy XP drivers are installed on main video adapter. Also, for Windows Vista x64 and Windows 7 x64 digital signature enforcement for kernel drivers is also applied (ZoneScreen driver do have authenticode signature but appropriate digital certificate costs a lot). So, virtual display driver is not loaded unless this enforcement is disabled.

Can anyone tell me if such a thing exists?

Just found this: http://virtualmonitor.github.io/ Looks like a work-in-progress and only supports windows 2000 - windows 7, but he's looking for help with windows 7 - 8.

  • Looks awesome! Starred the project, this is exactly what I've been looking for.. but seems like it has some distance to travel still. 4 years later... better late than never, i guess?

  • Unfortunately current 0.2.1 Beta release outputs "Unsupported Windows system" while I'm trying to install it on Windows 8.1 Aug 19, 2015 at 16:09

Perhaps the Quartics Virtual Display Driver helps you (google or look at your favourite download-page for it). If this is not what you need, following page could be interesting for you: http://forum.ultravnc.info/viewtopic.php?t=6408

    This display driver you mentioned was last updated in April of 2005. It is certainly not compatible with Windows 7 or Windows Vista. In addition, your link shows only a forum thread where people are asking the same questions that I am and providing answers I already mentioned here (ZoneOS).
