About Screen Resolution & Display Tier Checker
Real-time screen and viewport resolution diagnostic. Instantly inspect your current browser viewport width and height, physical device screen resolution, Device Pixel Ratio (DPR Retina scaling), color depth, orientation, and display classification (e.g. Full HD 1080p, 2K, 4K UHD).
Key Capabilities & Features
- Live viewport dimensions updating dynamically as you resize your browser window
- Physical hardware display resolution and color depth detection
- Device Pixel Ratio (DPR) calculation for Retina and HiDPI displays
- Display tier badge (FHD 1080p, 2K QHD, 4K UHD, Standard)
- Orientation detection (Landscape vs Portrait)
How to Use Screen Resolution & Display Tier Checker
Open Tool
The tool automatically detects your current viewport and physical screen dimensions.
Resize Window
Drag your browser window edges to see real-time viewport updates.
Check DPR
Review your Device Pixel Ratio to verify if high-DPI or Retina scaling is active.
Verify Display Tier
Confirm your monitor classification (e.g. 1080p, 1440p, or 4K).
Privacy & In-Browser Execution Guarantee
100% Client-Side. Screen metrics and viewport dimensions are read locally via browser window APIs.
Frequently Asked Questions
How does this diagnostic tool inspect screen and hardware capabilities?
The tool queries native client browser APIs (window.screen, devicePixelRatio, navigator hardware concurrency, and media queries) to report exact hardware specifications.
Is any of my device fingerprinting or hardware information logged?
No. The diagnostics run purely for your immediate inspection. No hardware identifiers, user agents, or screen dimensions are recorded or sent to any remote server.
Does this tool support high-DPI (Retina) and multi-monitor setups?
Yes. The tool accurately detects CSS logical pixels, device physical pixels, subpixel rendering ratios, and color gamut support (sRGB vs Display P3).
