Multiple Monitors

It is possible to connect two or three Monitors to your computer depending on the number of video ports on your motherboard or Graphics Card.

Adding more Monitors gives you a much larger desktop to view your programs and leads to a higher level of productivity.

Most Graphics Cards have at least two video ports and some have three or four. If you do not have a Graphics Card then the motherboard will most likely have at least two video ports.

The video ports may include the analogue VGA port, digital DVI port, digital HDMI port, or the newer digital DisplayPort connector.

Graphics Card Ports HDMI, VGA and DVI:

Graphics Card Ports VGA and DVI.

Connecting your computer to two Monitors and setting them up in Microsoft Windows:

Firstly, switch off your computer and have a look at what video ports are available on the back of your computer/Graphics Card. You most likely have one Monitor already connected to your computer. Look at your second Monitor and try to find a port which matches one on the back of your computer. For example, you might have your main Monitor connected to your computer via the DVI ports and your second Monitor connected to the computer via the VGA ports.

Once you have connected both Monitors, switch them on, and then boot up your computer.

Your computer may automatically detect the other Monitor and take you to a set-up screen. However, if only your main Monitor displays anything then you can enter 'Win + P' together on your keyboard. The Windows key (Win) is usually located at the bottom left corner of your keyboard and has the Windows logo on it.

Pressing Windows + P to set-up Monitors.

The screen should display 'Computer only', 'Duplicate', 'Extend', and 'Projector only'.

If you select 'Duplicate' then both Monitors will display identical images but if you select 'Extend' then this will extend your desktop. With 'Extend' selected you can open up a window on your main Monitor and drag it over to the other Monitor. 'Projector only' is for connecting a projector to your computer and selecting 'Computer only' will display on your main Monitor only.

Setting up the resolution on each Monitor:

Right-click anywhere on the desktop and select 'Screen Resolution' which will take you to a window where you can set the screen resolution for each monitor. You can also change the screen orientation, and select which Monitor is your main display.
