Ao usar 2 telas externas no meu laptop (via docking station conectada via displaylink), elas funcionam, mas a terceira tela tem lag (a segunda tela não funciona). Eu acho que pode ser por causa da nvidia não controlá-los (telas não são mostradas nas configurações do servidor NVIDIA X). Mesmo quando eu clico em detectar telas no programa nivdia, somente a tela do laptop é detectada.
driver instalado do displaylink 4.1.9.

Alguém sabe como posso fazer com que a nvidia reconheça essas exibições externas para se livrar do atraso?
