Step-by-Step Tutorial: How to Change Primary Monitor in Windows 10
Changing the primary monitor setting in Windows 10 allows you to specify which screen you’d like to be the main display for your desktop and taskbar. Here’s how you can do it:
Step 1: Right-click on the Desktop
First, right-click on any empty area of your desktop.
Right-clicking on the desktop will bring up a context menu. This menu offers various options, but we’re particularly interested in "Display settings".
Step 2: Select "Display settings"
From the context menu, click on "Display settings".
This will open the Display settings window where you can configure various display-related options, including setting the primary monitor.
Step 3: Identify Your Monitors
Click on the "Identify" button to display the number on each monitor.
This step helps you figure out which monitor is which by displaying a number on each screen. This is useful if you have multiple monitors and want to ensure you’re selecting the right one.
Step 4: Select the Desired Monitor
Click on the monitor you want to set as primary.
When you click on the monitor you wish to make primary, it will be highlighted. This is an essential step because you’ll be making changes to this highlighted monitor.
Step 5: Check "Make this my main display"
Check the box that says "Make this my main display."
Checking this box will immediately set the selected monitor as your primary display. This action will move your taskbar and desktop icons to the chosen monitor.
Step 6: Apply the Settings
Click "Apply" to save your changes.
After you’ve made your selection, clicking "Apply" will save the settings, making your chosen monitor the primary display.
Once you’ve completed these steps, your selected monitor will become the primary display. The taskbar and desktop icons will move to the new primary monitor.
