In order to setup Dual monitor in Windows 8, refer to the tutorial below.
What is Dual Monitor?
Dual Monitor is nothing but the ability to use two display devices such as monitor, television or/and projectors, in a single computer. The idea of Workspace in Linux is also the same. It is also known as Dual-Display or Dual-Screen. It is used in a computer normally in the Extended Mode .
What is Extended Mode?
Most of the current video cards are capable of spanning a single frame buffer across two monitors. The result is one large rectangular desktop space, of double either the horizontal or vertical resolution. As an example, when you use two 1024×768 displays, you can have a combined virtual resolution of either 2048×768 or 1024×1536. In the Extended mode, additional desktop area is created by giving each monitor its own frame buffer. In this mode, each monitor can be of different resolution, depth, and refresh rate.
