Changing the display resolution on a Windows machine can enhance your viewing experience by optimizing the clarity and size of the content on your screen. Windows provides several ways to adjust the resolution, whether through the graphical user interface or via command line tools like PowerShell. This article will guide you through the process of changing the display resolution using both methods.

Method 1: Using the Display Settings

1. Access Display Settings:

   • Right-click on the desktop and select "Display settings" from the context menu.
   • Alternatively, you can go to "Settings" > "System" > "Display".

2. Change Resolution:

   • In the Display settings window, scroll down to the "Display resolution" section.
   • Click on the dropdown menu to see the list of available resolutions.
   • Select the desired resolution. Windows will apply the change and prompt you to confirm it. If the screen looks good, click "Keep changes."

3. Advanced Settings:

   • For more advanced options, click on "Advanced display settings" at the bottom of the Display settings page.
   • Here, you can view detailed information about your display and make further adjustments if necessary.

Method 2: Using PowerShell

PowerShell can be used to change the display resolution programmatically. However, it requires additional modules or scripts since there is no built-in cmdlet for this purpose. One popular module is DisplaySwitch.

1. Install DisplaySwitch Module:

   • Open PowerShell as an administrator.
   • Run the following command to install the DisplaySwitch module:

     Install-Module -Name DisplaySwitch -Scope CurrentUser

2. Change Resolution:

   • Use the Set-DisplayResolution cmdlet to change the resolution. For example, to set the resolution to 1920x1080, use:

     Set-DisplayResolution -Width 1920 -Height 1080

3. Verify the Change:

   • You can verify the current resolution by using:

     Get-DisplayResolution

Note: Changing the resolution via PowerShell might require a system restart to apply the changes effectively.
