How to have a multiple monitors or displays on a computer
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.
Video card with multiple connections
High-end video cards and computers have video cards with multiple DVI or HDMI connectors. Computers with these cards support a different monitor for each connector. In the example picture, this video card has two DVI and two HDMI connectors that can be used to connect multiple monitors to the same computer.
Multiple video adapters
Installing multiple video cards or video cards that support multiple displays into your computer allows you to connect multiple monitors to your computer.
Laptop dualview mode
Laptop or desktop computers with advanced video cards that support dualview mode can duplicate what is being displayed on their computer or stretch the display horizontally or vertically. Once another external display has been connected to the computer you can use dualview mode in Microsoft Windows by following the steps below.
- Open the Control Panel
- Double-click Display.
- In the Display properties window, click the Settings tab.
- In Settings tab, under the Display heading, click the down arrow, and select the secondary display connected to your computer.
- Once selected, check the Extend my Windows Desktop onto this monitor option.
If your external display is not shown by Windows, your computer does not support this feature.
