What is My Screen Resolution? Understanding Monitor Resolution
Your screen resolution or monitor resolution is the number of pixels your display can show, measured in width × height (for example, 1920×1080). When you check your screen resolution, you'll see these two numbers that define how much detail your monitor can display. Higher monitor resolutions provide sharper images and clearer text, though interface elements may appear smaller. Our tool helps you instantly check what your screen resolution is and understand your display capabilities.
What Screen Resolution Information Reveals
- Display Dimensions: The exact pixel count of your monitor's width and height.
- Available Space: The usable screen area after accounting for taskbars and system UI elements.
- Pixel Density: How many device pixels correspond to each CSS pixel, affecting sharpness on high-DPI displays.
- Color Capabilities: The bit depth determining how many colors your display can show simultaneously.
- Aspect Ratio: The proportional relationship between width and height (16:9, 4:3, etc.).
Common Resolution Standards
Display resolutions are standardized to ensure compatibility across devices. HD (1280×720) and Full HD (1920×1080) are common for everyday use, while 4K (3840×2160) provides ultra-sharp detail for professional work. Understanding your resolution helps optimize content viewing and workspace organization.
Viewport vs Screen Resolution
Your browser's viewport may differ from your physical screen resolution due to browser UI, zoom levels, and window sizing. Web developers need both measurements to create responsive designs that work across different viewing conditions. The viewport represents the actual area available for web content.
High-DPI and Retina Displays
Modern displays often use pixel multiplication to display crisp content at comfortable sizes. A Retina display might have a 2560×1600 physical resolution but appear as 1280×800 for interface purposes. The pixel ratio indicates how many physical pixels represent each logical pixel, crucial for proper image and interface scaling.
