Windows 10 Anniversary OpenGL Drivers Ancient

[AlbanRampon]

Hello CML,

Windows 10 v1607 is a new operating system. It looks like v1511, it is also called 10 but it is a different OS, with a different graphics subsystem. Whether your GPU vendor and the driver you have supports it or not is not appropriate for me to comment on. Microsoft indicated that is the root cause for your issue. My contacts are the people who designed the API and be certain they also want it to work properly!

DisplayLink driver does not interpret OpenGL and never has done so. There is no way to tell DisplayLink driver to interpret OpenGL and select what to do with it because DisplayLink is not a GPU. Here, DisplayLink drivers will get computed pixels = the driver has NO visibility/access to the OpenGL API calls or applications running. That's up to the kernel mode driver.
DisplayLink is not able to solve these third party shortcomings. We do not have control over that code base and the information I have is from third parties.

You may also wish to switch to the Windows 10 LTSB if you believe your GPU vendor will never address the Windows 10 Anniversary Update operating system requirements and if you don't wish to receive the Windows Updates for Windows 10 v1607 yet. If you want to install 7.9 M7 on it and take the responsibility of the consequences of that attempt, then you are free to do so.
DisplayLink driver 7.9 is incompatible with WDDM 2.1 primary graphics card drivers and not supported on Windows 10 v1607. If you then start using a WDDM 2.1 primary graphics card driver, you *will* have issues, upto not being able to use the computer. That is why DisplayLink driver 8.0+ is the minimum version supported on Windows 10 v1607.

I am as frustrated and almost as powerless as you are.
Please do ask your GPU vendor to provide graphics drivers for Windows 10 v1607 so we can get this progressed.

Regards,
Alban

Hi Alban,

I need some technical insight from you about this issue.

I'm using the laptop with a hdmi connection to the monitor, works perfectly fine (Nvidia GT 740M). Phototeca (needs OpenGL 2.0+) also runs smoothly.
As soon as I switch the monitor to the dock, only the integrated intel HD 4400 works, without OpenGL 2.0 (or whatever is the current version).

I understand WDDM 2.1 has a new method, but it did not disable the drivers in the laptop. I have the latest drivers for the dock and graphic card, according to the computer.
That is why I brought up the possibility about the USB port. If the Dynadock driver works perfectly, only a few explanation remained, I think (only by sheer logic, not with technical knowledge):
1. Windows 10 makes Dynadock unusable. But only part of the graphics.
2. Update (version 1607) has a bug, that prevents Dynadock identify OpenGL and second graphic card through the USB port.
3. Dynadock driver has a blind spot in communication with Windows, because of the update. It should work, but cannot.

Based, on what you wrote to CML, the dock only takes the final picture, and forwards it to the monitor. Still, the laptop can use everything, but the dock can not.

Please help me understand the situation, because I want to turn to Microsoft, and I would not run the same rounds again and again, manufacturers pointing at each other.

Good afternoon,

Microsoft confirmed to me the issue lies with the graphics driver.
They have created a bug report to Intel about this.
The reference of the bug from MS to Intel, should you wish to help push for a fix, is "Sysdev 10134913".

Kind regards,
Alban
