Adding a second screen to your PC or laptop gives you more space to multitask: you can browse the web, check emails, complete work tasks, watch videos and lots more spread across two displays. Here's how to connect a monitor to a laptop.

This is an easy task really. Modern laptops will offer at least one port that can be used to connect a monitor, be it HDMI, VGA, DVI, or DisplayPort - although some may require an adapter to do so which isn't always supplied in the box. PC users will need to be running a graphics card with two such ports.

The simplest solution is to choose a second monitor with a matching port and connect the two, although it’s possible to mix and match some of the digital options. It’s then just a case of configuring Windows to use both screens.

Step 1. Find a spare connection on your laptop and make sure you have a cable that will connect it to the monitor. Connect the port to a matching port on the new screen and it should automatically detect it (otherwise change the source input).

Step 2. Click Start, Settings and System. Here you'll find the Display menu (by default) to reach settings like orientation, size and brightness.

Step 3. You can have various different configurations for the two screens.

• Duplicate: The second monitor mirrors the primary monitor.
• Extend: The desktop of your PC is extended across the two monitors and allows you to have a desktop that spans across both monitors.
• Show only on 1 or 2: Only one of the displays will be used (click Identify to find out numbers).

Step 4. Adjust the resolution for each screen to improve the quality of text and video shown onscreen. From the Display menu, select Advanced display settings. Use the drop down box to adjust the screen’s resolution. It’s advisable to use Windows’ recommended resolution for each display.
