The connection is wireless, so it’s not quite the same experience as having a second monitor connected by cable, but it can be useful if you’re stuck and need a solution.

Setting up a laptop as a second monitor

Before you start, make sure that the monitor(s) are properly connected to the PC. Once you have made sure, you’re good to go. Here is the configuration process to use your laptop as a monitor:

  1. Open the Start menu by clicking on the Windows logo in the lower-left corner of the interface.
  2. You will then see a wheel icon in the column to the far left of the pane that just opened, just above the Power button. Click it to access the Settings.
  3. Then select “System” at the top left.
  4. By default, you will land in the display options. In most cases, the computer is supposed to detect your various connected screens. If it does not, click the “Detect” button to make it try to recognize them.
  5. Then, scroll to the bottom of the dialog box to land in the “Multiple Displays” section. In “Multiple Displays“, choose the setting that suits you best. “Duplicate these displays” allows you to have the main display on both screens (and thus duplicate). This is especially useful when using a monitor with a laptop as the CPU. “Expand these displays” allows you to display a larger working area. A particularly effective option with two monitors positioned side by side, glued together if possible, and with thin borders for a better effect. In short, your two monitors become one. With “Show only on 1“, screen 2 remains unused. The same idea with “Show only on 2“, screen 1 remains black.

You have configured your setup with two screens, enjoy! In the same menu, you can also set up night lighting to adjust the brightness when it starts to get dark, change the resolution of the screens, the scaling of the elements, or the orientation of the display (portrait or landscape). Adjusting colorimetry, refresh rate, and other more advanced settings is another story.
