Failed to Initialize D3D 9 Device

[Jankos]

I also have this issue when trying to run a game with displaylink manager installed.

I found that I can run them in windowed mode and they play fine but if they try to run in fullscreen mode it will crash and give an error. I have been getting around this by running windowed mode but some games you can't do this with or can only do this once you get to the settings ingame.

I can provide more info if needed.
