¿Qué es Monitor & Resolution Info?
Monitor & Resolution Info instantly reads and displays your screen's technical specifications directly from the browser: logical resolution, physical pixel count, device pixel ratio, color depth, display orientation, estimated refresh rate, and aspect ratio — with no installation or permissions required.
Cómo usar Monitor & Resolution Info
- Open the tool and all display stats are shown immediately.
- Resize your browser window to see the viewport dimensions update in real time.
- Move the browser to a different monitor to detect that display's properties.
- Click 'Refresh' to re-run the refresh rate estimation.
- Click 'Copy all info' to copy a formatted summary to your clipboard.
Ejemplos
Retina display check
Entrada: MacBook Pro 14" — Device Pixel Ratio: 2
Salida: Logical: 1512×982 | Physical: 3024×1964 (Retina)
4K monitor
Entrada: 27" 4K display at 100% scaling
Salida: Screen: 3840×2160 | DPR: 1 | Aspect: 16:9 | Refresh: ~60 Hz
Mobile browser
Entrada: iPhone 15 Pro (portrait)
Salida: Screen: 1179×2556 | DPR: 3 | Orientation: Portrait
Errores comunes
- Confusing logical resolution with native resolution — always check the Device Pixel Ratio to understand the relationship between CSS pixels and physical pixels.
- Reading stats while the browser is not maximized — for accurate screen resolution numbers, ensure the browser is in fullscreen or compare with your OS display settings.
- Assuming the refresh rate estimate is exact — the rAF-based measurement is a good approximation but may vary slightly under CPU load.
Por qué usar esta herramienta
- No permissions required — all data comes from standard browser APIs.
- Updates in real time as you resize the window or change orientation.
- Detects Retina / HiDPI displays via device pixel ratio.
- Copy-to-clipboard makes it easy to share specs when debugging layout issues.
