How to change the screen resolution?

The standard webpage size for desktops typically has a maximum width of 1440 pixels. This width is chosen due to the prevalence of wider desktop resolutions like 1920x1080. However, modern websites prioritize responsiveness, which means they dynamically adapt to different screen sizes and do not rely on fixed dimensions.

To change the screen resolution, follow these steps:

For Windows:

  • Right-click on the desktop and select Display settings.
  • Under Display, you'll see a slider for Screen resolution. Move the slider to the desired resolution, and click Apply.
  • If the resolution you want is not available, click Advanced display settings and then click List all modes. Select the desired resolution from the list and click Apply.

For Mac:

  • Click the Apple menu button in the top-left corner of the screen.
  • Click System Preferences.
  • Click Displays.
  • Click the Scaled option.
  • Select the resolution you want to use.
