Dell P2414H keeps freezing with USB 3.0 Plugable Dock

I have a Plugable USB 3.0 docking station and a Dell P2414H Monitor. Monitor will just work fine for a few minutes and then just freeze up. I power down the docking station and it may or may not work. Everything else plugged into the dock works just fine whether the monitor is working or not. I am using a DVI cable to connect the monitor to the dock.
