A:Answer a external monitor connected to this, will not increase the FPS. the FPS is depending on graphics card, internet connection, and system resources. I have connected a monitor (144mhz) to the laptop and the monitor never exceeded 75mhz. But, the laptop still stayed at 165mhz with avg FPS of 110 on high settings. So I would say the only way you will get high FPS on a external monitor with connecting to this, you would need a external video card to push the framerate.
Just my opinion on this and your mileage may very.
