Hello community,

I use now a i-tec USB2.0/USB-C docking station to make it possible to use laptop and desktop in an easy way. The laptop works fine, but I have problems with my desktop.

The desktop use an Radeon HD7450 graphic card and windows 10.

If I want to open 3d tools I get the Errors:
- Missing library 87
- "Could not probe OpenGL. This program requires OpenGL 2.0 or higher. Please check your video card drivers."

I get the second error also with Intel HD4000, if I remove the HD7450.

But displaylink homepage describes, that both are the Minimum requirement for using this docking stations. Also 3 other docking stations led to the same errors.

What I already found out:
- If I plug one of my two Displays directly into the graphic card, I can start the 3d tools by pushing the icon on that Display. if I want to open it on the other one, it also leads to that errors.
- If I use both monitors over displaylink, it seems that the graphic card ressources can not be used by displaylink and I can not open Catalyst 15.7.

What can I do to solve that issue? Could a new graphic card be compatible or is it not possible to use desktop PCs with displaylink?
