Nirav : the best way is to connect an external monitor to d laptop using vga cable nd use it as extended monitor. Quite simple but key is to hv one lappy nd one monitor. Having 2 laptops doesnt help. I tried connecting laptop to laptop, laptop to my tab (galaxy 10.1) using some app but none seem to work. So i will wait till my extra monitor is back from repair.
If somehow it is possible to run multiple instances of ZT Nest on 2 laptop then it wud be great
