How to Change and update Screen Resolution

Overview

Screen resolution controls how large or small items appear on your screen, including text, icons, and windows.

If your screen looks:

• Blurry
• Too zoomed in
• Too small
• Cut off on the edges
• Stretched

You may need to adjust your screen resolution.

What Is Screen Resolution? (Non-Technical Explanation)

Screen resolution determines how much information fits on your screen.

• Higher resolution = More space on your screen, smaller text and icons
• Lower resolution = Less space on your screen, larger text and icons

Think of it like adjusting the zoom level on your computer.
