A free, advanced online tool to instantly detect your Screen Resolution, Browser Viewport, and Color Depth. Automatic and real-time.
Advanced Display Analyzer Tool
Welcome to our free Advanced Display Analyzer. This simple, instant tool provides you with key technical details about your display setup. Whether you're a web developer, a designer, or just curious about your screen's specifications, you've come to the right place.
Your results are automatically calculated and displayed by the tool on this page.
How to Use This Tool
It's completely automatic! As soon as you load this page, our tool detects and displays your screen information.
- View Your Results: The values shown in the analyzer card are live data from your device.
- Resize Your Browser (Optional): Try resizing your browser window. You will see the "Browser Viewport" numbers change in real-time, while your "Screen Resolution" stays the same.
Understanding Your Results
Our tool provides three key pieces of information. Here’s what they mean:
1. Screen Resolution
- What it is: This is the total number of pixels on your physical monitor. For example,
1920px × 1080pxmeans your screen has 1,920 pixels horizontally and 1,080 pixels vertically. - Why it matters: This represents the maximum detail your monitor can display. This value is fixed and does not change when you resize your browser.
2. Browser Viewport
- What it is: This is the visible area of the webpage inside your browser window. It does not include browser toolbars, address bars, or the scrollbar.
- Why it matters: This is the most critical metric for web developers. It shows exactly how much space is available to display the website. This value will change as you make your browser window larger or smaller.
3. Color Depth
- What it is: This measures the number of bits used to represent the color of a single pixel. A
24-bitcolor depth (which is most common) means your monitor can display approximately 16.7 million different colors. - Why it matters: A higher color depth results in richer and more accurate colors.
Who is This Tool For?
This tool is useful for a variety of tasks:
- Web Developers & Designers: To test responsive designs and see how a website looks on different viewport sizes.
- QA Testers: To report bugs and specify the exact screen and viewport resolution they are using.
- Technical Support: To help diagnose display issues with a user's computer.
- Curious Users: To quickly find out the technical specifications of their monitor or mobile device screen.
Frequently Asked Questions (FAQ)
What is the difference between Screen Resolution and Browser Viewport?
Screen Resolution is the total pixel count of your entire physical screen (e.g., 1920x1080). Browser Viewport is only the usable, visible area inside your browser, which is almost always smaller.
Why is my viewport resolution smaller than my screen resolution?
Your operating system (like Windows or macOS) uses space for the taskbar, and your browser uses space for the address bar, tabs, and scrollbars. The viewport is the remaining space for the website content.
What is the most common screen resolution?
As of 2025, 1920x1080 (also known as 1080p or Full HD) is one of the most common desktop screen resolutions. For mobile devices, the resolutions vary widely.
