Degraded performance after Win8.1 update

More clarification: the interaction is between the mode switching of the Yoga, the external monitor plugged into the UD-3900, and an external mouse. There is never a lag problem on the laptop screen, whether in stand mode or not.

I've also tried disabling the touchpad manually and then folding the keyboard back to switch modes, but it does not make a difference. As soon as the Yoga switches modes (disables keyboard/mouse), video performance on the external monitor goes downhill.
