What is Native Resolution?

The physical number of pixels integrated into the display panel. For maximum clarity, your operating system settings should always match this native resolution.

Screen Resolution Check

This high-precision diagnostic uses the browser's hardware-acceleration engine to identify the exact pixel count of your display. Whether you are using an Apple Retina display, a 4K gaming monitor, or a smartphone, we provide zero-software confirmation of your specs.

Physical vs. Viewport Resolution

Your **Physical Resolution** is the total number of pixels on the hardware (e.g., 3840x2160 for 4K). However, modern browsers use **Viewport Resolution** (scaling) to make text readable on high-DPI screens. Our tool identifies both to help you calibrate your design or gaming setup.

Understanding Device Pixel Ratio (DPR)

DPR represents how many physical pixels are used to render a single CSS pixel. An Apple MacBook typically has a DPR of 2.0, meaning it uses 4 physical pixels (2x2) for every 1 visual pixel, creating an ultra-sharp "Retina" look.

Common Aspect Ratios

  • 16:9 (Widescreen): The standard for modern TVs and monitors.
  • 4:3 (Traditional): Common for older CRT displays and iPads.
  • 21:9 (Ultrawide): High-end cinematic and gaming monitors.
  • 16:10: Popular on productivity-focused laptops like MacBooks.
