When actually it is an unsupported hack only. That's why it is sometimes even called "Industry Standard" for USB displays USB display vendors (including the market leading one) typically use this approach. There are two ways of doing what you intend to do.īoth are not supported by Microsoft Windows.īoth are far beyond the reach of regular diver developer skills. For my project, I really need Windows 10 export a virtual extension screen. I have an idea about generate a virtual display monitor: in WDDM driver initialization stage, we mask all hardware relatedĬontrol(I2C EDID read, DPCD and other), and return all default EDID and other default value to dxgkernel DDI module, I have tried this, but not success(while install driver, device manager always return error code 0x1F).ĭo you have a way to let Windows 10 export a virtual display if OS not support virtual WDDM display adapter?ĭesktop Duplication, it is not what I want. What do you think about how they implement it? Other apply, all of them seems generate a virtual display monitor by WDDM driver, and Windows 10 will launch a app automaticallyĬapture this virtual display monitor then send image to Ipad/Monitor through USB cable or wireless. Such as usb display adapter or use IPad as secondary extension screen through wireless or usb cable and some
Thanks for your reply, really appreciated. Does this mean I need to configure a user display driver?Īnyone can give me advise about how to implement a simple virtual display driver would be very very appreciated.
Is 0xC00000BB while both “DriverEntry” and “DxgkDdiAddDevice” return STATUS_SUCCESS. Hi All, I need to develop a virtual display adapter driver on Windows 10, for mapping virtual extension screen to IPad, IPad as a phisical "monitor".īefore Windows 8, we can use mirror driver to develop such a virtual display driver, but now, Windows 10 already updated graphics infrastructure to WDDM, so my driver cannot work any more on new OS.Ĭurrently, I did some test based on Windows 10 WDK 10 provided sample video driver source code, but there is no lucky, I noticed the sample video driver just a miniport kernel driver, no user space display driver(.dll), according from WDDM design guide,ĭisplay driver should include user space display driver(.dll), but why WDK 10 sample code didn't include it?Īs for modified miniport driver(no user space driver), I cannot success install it, device manager always return error message 0x1F, and problem code
