My system consists of Laptop + one HDMI monitor + one USB display monitor (ASUS MB169+). I have tried to use triplication of screen with Displayfusion in Win 7 32 bit. It greatly works, however, Microsoft 2013 does not work well in the USB dysplay monitor. When I type words in MS office (word, excel, ppt), the HDMI monitor shows them promptly but ASUS does not. Other programs, e.g. web browsers or other word processor are working well in the all three monitors. Do you have any solution for this problem?
