SuperSpeed USB 3.0 w laptop and two monitors: screen blinking & configuration issues

I just hooked up my plugable to a ASUS laptop (N550JK) and two ViewSonic monitors. I have two issues:

  1. The laptop screen is blinking, about twice a second. I’ve checked the connections and tried lowering the resolution. No change. This will give me a migraine.

  2. The two monitors display my wallpaper, but that’s it. When I click on something from the Windows toolbar from a monitor, the item comes up on the laptop screen. Of course, I’d like things to come up on and be moveable between my two monitors. I’ve selected “Extend desktop.” What am I missing?
