Know Your Pixels with Screen Resolution
In a multi-device world, knowing your exact screen dimensions is crucial. The **Screen Resolution** tool at **Online Tool Base** instantly detects your display's logical resolution, physical screen size, and color depth. It analyzes the viewport to tell you exactly how much space is available for web browsing.
This information is vital for web designers testing responsive layouts, or for gamers configuring their display settings. **onlinetoolbase.online** breaks down the difference between your window size (viewport) and your total screen size. It also reports the Device Pixel Ratio (DPR), helping you understand if you are viewing on a Retina or High-DPI display.
Why Use This Tool?
Hardware specs can be confusing. You might have a 4K monitor, but your scaling settings make it behave like 1080p. Our tool clarifies this by showing you the "CSS Pixels" used for rendering versus the raw hardware pixels. Use it to check if your monitor is set up correctly or to gather specs for a bug report.
Key Features
- Dual Detection: Shows both Window Size (Viewport) and Screen Size (Monitor).
- Color Depth: Checks bit-depth (e.g., 24-bit True Color).
- Orientation: Identifies Landscape or Portrait mode.
- DPR Check: confirms High-DPI scaling factors.
How to Use
- Open the tool; detection is automatic.
- Read the resolution figures displayed.
- Resize your browser window to see the 'Viewport' numbers change in real-time.
- Check the 'Pixel Ratio' to verify screen density.
