What drivers shall I downgrade to have it work? Can you help me with this? Even in e-mails, or another thread? Or should i turn to Microsoft?

I have tried previous graphic drivers (even with complete removal of the NVidia driver).

Good afternoon Kalman,

The old driver is not expected to work because this is a new OS feature in Windows 10 Anniversary Update. Therefore the driver would never have supported this.
In previous versions of Windows, instead of using (now) standard OS calls, we used a different methods.

The previous method could cause stability issues as each graphics driver update and months of work with each new version of Windows, especially in mutli/hybrid graphics systems... With Microsoft churning versions of the OS every two weeks through the Windows Insider Program, the few month development each time wouldn't have quite worked. Also, the new standard OS calls mean that having DisplayLink work is important to Microsoft as we helped design/develop it.

At the moment, I am waiting for Microsoft feedback to know what will happen next. And they are waiting for the graphics vendors to inform them about their progress.
If it turns out that the graphics vendors have actually already implemented the changes to pass-through the OpenGL, then the solution will be elsewhere.

Kind regards,
Alban

I have a Dell XPS laptop with Nvidia 960M which runs OpenGL 4.4 on Windows 10 Home (Build 14393.693). I connect to a larger monitor via the Dell D3100 docking station.

Recently I have noticed some OpenGL applications which I have coded in the past (and worked fine) have started to not work properly when I have try and run them when attached to the larger monitor via the dock. I am certain this wasn't the case until recently and have replicated these issues with demo OpenGL apps from trusted sources.

Upon closer examination I have found that if I have the screen set to "display only on 2nd display" i.e. large monitor on / laptop screen off (which is how I normally run my setup when in the office), the OpenGL version registered as running is as follows:

Running on a GDI Generic from Microsoft Corporation
OpenGL version 1.1.0 is supported

However if I try and run with only my laptop screen or the screen set to "extend" i.e. both large monitor and laptop screen on, I get the following:

Running on a Intel(R) HD Graphics 530 from Intel
OpenGL version 4.4.0 - Build 20.19.15.4474 is supported

Note:- Due to the strange way the Dell XPS display system is built, you can't turn off Intel Graphics / enforce the nVidia driver at all times, the system decides as and when which to use..

Clearly something is wrong here as OpenGL 4.4 is installed on the system, but when I have display on 2nd screen only it seems to pick some weird generic driver.
