Frequently Asked Questions

Resolution is the number of pixels displayed on your screen (e.g., 1728x1117), which may be scaled by the operating system. Native resolution is the actual pixel count of the display hardware (e.g., 3456x2234 for a Retina MacBook), accounting for pixel density (pixel ratio).

Pixel ratio (e.g., 2x) is the scaling factor between logical pixels (used by the OS) and physical pixels (hardware). High pixel ratios (e.g., Retina displays) make images sharper but may reduce visible resolution.

Aspect ratio is the proportional relationship between a screen's width and height (e.g., 16:9). It affects how content is displayed and is calculated from the resolution.

We match your native resolution to a database of known devices (e.g., 3456x2234 for MacBook Pro 16). If no match is found, we estimate size using typical PPI values based on device type (phone, laptop, monitor).

We identify devices based on unique resolutions and operating system. For example, 3456x2234 on macOS likely indicates a MacBook Pro 16. Non-unique resolutions (e.g., 1920x1080) show a resolution name like "1080p."

We detect the OS using browser data (e.g., "macOS" for Macintosh, "Android" for Android devices). This helps filter device matches to ensure accuracy.

Megapixels represent the total number of pixels in a screen (width × height ÷ 1,000,000). For example, a 3456x2234 display has ~7.72 MP, indicating its pixel density.

The resolution checker compares your native resolution to common standards (1080p: 1920x1080, 4K: 3840x2160) to help you understand your display's capabilities for gaming, video, or professional use.

IP details (Public IP, Region, Country, ISP, Timezone) are fetched from a reliable API. Accuracy depends on your network (e.g., VPNs may obscure location). We display "Not Available" if data is missing.
