Mac OS ventura ; black videos on any browser or app

[pierregiraudet]

I just installed display link manager, have a Mac book pro, with to additional monitor, when a use display link app, I can not read any video, the sound is ok but videos are black ever screens, browsers a used even the Mac book screen it self, when I disconnect the usb c idsonix docking station where the two screens are plugs, I can read videos again normally ? Could it be the app display link manager or the way i plug the doc station?

thanks for your answer
