Now a days Laptops got many features it does supports dual displays or dual monitor's aswell, one thing is you need to have good capable graphic card. you can connect with HDMI port or a VGA port, DVI port is that is not available for Laptops.

Connect the VGA cable of a  monitor to the Laptop VGA and as there is built in shortcut on the keyboard of a Laptop. Fn is the Function enabling key and you need to hold and press the dual displays button which is on the  0-9 keys on the keyboard.

If you press first time display will be switched to external monitor, pressing second time display will be switched to laptop monitor and pressing third time means it runs on dual display. Resolution may be effected in the external monitor.
