Working on two screens simultaneously allows you better visibility, to be more efficient and faster in the execution of your tasks. In addition, connecting a computer to an external monitor is very simple, especially thanks to the various ports available, namely HDMI, VGA, DVI, or DisplayPort. In this tutorial, we explain the different steps to follow to connect your devices together.
Connect a display to your laptop
The first thing to do is to identify which ports, among those mentioned above, are present on your device.
Then, if you can, then choose a screen with the same connections as your monitor, so that you only need a cable to connect them, there are also mixed ones (DVI to VGA, DVI to HDMI …).
Once you find your display and cable, configure the display of your two displays. To do this:
- Connect your screen to your laptop. In most cases, Windows will automatically detect when a monitor is plugged in and turned on. Otherwise, double-check your connections.
- Go to your Start menu and click on Settings, then select System then Display.
- If your screen was not detected during the previous step, you can click Detect in the Display subsection.
Duplicate Windows Desktop on Two Displays
There are three ways to determine the display on each of the two screens. Here are which ones:
- Duplicate: to reproduce your computer screen identically on your second screen.
- Extend: to link the two displays so that they function as a single unit.
- Show only on X: to display your computer only on the chosen screen.
The best way to treat your second monitor as a separate office would be to choose the “Extend these displays” option.
To switch from one mode to another, press the Fn key on your keyboard and scroll through the different configurations: laptop display only, laptop + external screen, the external screen only.
Once you have chosen the type of configuration that suits you, all you have to do is adjust some details like screen resolution or brightness, then click on Apply.
Now you can use your external monitor as your laptop screen, place shortcut icons on it, open apps, and even run multiple apps.
