Screen resolution is a crucial aspect of your display settings, impacting the clarity and size of text, images, and videos on your screen. In Windows, adjusting the screen resolution can enhance your viewing experience, whether you're working, gaming, or watching videos. This guide will walk you through the process of changing screen resolution using both the graphical interface and command-line tools in Windows.

Adjusting Screen Resolution via the Settings App:

1. Open Display Settings:

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

2. Change Resolution:

   • In the Display settings window, scroll down to the "Scale and layout" section.
   • Click on the "Display resolution" dropdown menu.
   • Select the desired resolution from the list. Windows will recommend an optimal resolution marked as "(Recommended)."

3. Apply Changes:

   • After selecting a resolution, click "Apply."
   • A prompt will ask you to confirm the change. If the screen looks good, click "Keep changes." If not, select "Revert" to go back to the previous resolution.

Adjusting Screen Resolution via Command Line:

While Windows does not natively support changing screen resolution via CMD or PowerShell, you can use third-party tools like "QRes" or "Nircmd." Below is an example using QRes:

1. Download QRes:

   • Download QRes from a trusted source. Ensure it's compatible with your version of Windows.

2. Install QRes:

   • Extract the downloaded files to a directory, e.g., C:\QRes.

3. Change Resolution via CMD:

   • Open Command Prompt as an administrator.
   • Navigate to the QRes directory using the cd command:

     cd C:\QRes

   • Execute the QRes command to change the resolution. For example, to set the resolution to 1920x1080, use:

     QRes.exe /x:1920 /y:1080

Examples:

• Using PowerShell to Get Current Resolution:

  You can use PowerShell to query the current screen resolution:

  Add-Type -AssemblyName System.Windows.Forms

  This script will output the current screen resolution of the primary display.
