What Is Screen Resolution?
Screen resolution refers to the number of pixels your display can show horizontally and vertically. It's written as width × height (e.g., 1920×1080). Higher resolution means more pixels, which can result in sharper images and clearer details on your screen.
Knowing your screen resolution is helpful for:
- Creating responsive web designs that look great on all devices.
- Designing apps and graphics that fit correctly on screens of different sizes.
- Troubleshooting display settings on monitors, laptops, tablets, and phones.
