I bought two Dell U2414H's and have one hooked up so far to the docking station with a mini displayport cable. I had to set the refresh to 60 hertz in order for it to not go into a weird loop of on/off. So right now I have it all up and looks great, however any video I try to play basically plays in slow motion. I've tried Plex, Slingplayer, youtube. If I move the video the surface screen it does the same thing too. I have the updated intel driver installed from Intel but it doesn't seem to matter. I can't figure out why any video I play looks like it plays in slow motion. It also has no audio during this too. Could it be a bad cable? Anyone else run into this and know a fix? It's not usable for anything video related when I have the monitor hooked up. Edit: Oddly enough, this was a problem with audio. The Dell Monitor must have speakers and the Surface made the default audio device the monitor. I changed it back to the dock and immediately video was smooth again.
