❓ Frequently Asked Questions
How do I check my screen resolution?
Your screen resolution is automatically detected and displayed at the top of this page. It shows your width x height in pixels.
What is screen resolution?
Screen resolution refers to the number of pixels displayed on your screen, expressed as width x height (e.g., 1920x1080). Higher resolution means more detail and sharper images.
What is my monitor size?
Monitor size (in inches) is the diagonal measurement of your screen. This tool shows your pixel resolution; physical size requires knowing your screen's DPI (dots per inch).
What is aspect ratio?
Aspect ratio is the proportional relationship between width and height. Common ratios are 16:9 (widescreen), 16:10, and 4:3 (traditional). We calculate yours automatically.
Why is my resolution different from my monitor specs?
Your browser may report a different resolution due to display scaling, browser zoom level, or running in a window vs fullscreen mode.
How can I test my screen quality?
Look for dead pixels, color accuracy, and response time. Our tool helps identify resolution and aspect ratio for display testing purposes.
