Below is a listing of some of the most common methods of having a computer with multiple monitors as a display.


The most common method of connecting multiple monitors is to use a hardware solution. A video card with multiple connections, multiple adapters, using a laptop dualview mode, or using an external hardware device are all examples of hardware solutions.

Once another external display is connected to the computer you can use dualview mode in Microsoft Windows by following the steps below.

  1. Open the Control Panel
  2. Double-click Display.
  3. In the Display properties window, click the Settings tab.
  4. In Settings tab, under the Display heading, click the down arrow, and select the secondary display connected to your computer.
