[osg-users] Crash on Windows 10 with a Display Link adapter

[Fabien CLaudot]

Hi,

We have a crash in OSG in the following setup :
- Microsoft Surface Pro 4 with Windows 10.
- Application is displayed on a deported screen using a Display link adapter (Main screen is off).

Crash happens in the module osg130_osg

We get these error messages : Windows Error #127: [Screen #0] ChooseMatchingPixelFormat() - wglChoosePixelFormatARB extension not found, trying GDI. Reason: The specified procedure could not be found .

Error: OpenGL version test failed, requires valid graphics context.

On other platforms or with the main screen on, we get no error.

Thanks for your help.

Fabien.

 That looks very much like a driver problem. The application failed to create a proper OpenGL context that OSG needs, so the application crashes. The DisplayLink adapters are an external GPU and it may not support OpenGL properly. 

You are not the only one having problems with these adapters and Windows 10:
