Display Intelligence FAQ
What is the difference between physical resolution and viewport size?
Physical resolution refers to the total number of hardware pixels on your screen. Viewport size is the 'CSS pixels' used for layout. High-DPI screens in 2026 use multiple hardware pixels for every CSS pixel to ensure maximum sharpness.
Why should I use a professional screen size checker?
US designers and developers use it to verify breakpoints, test responsive layouts, and ensure that UI elements like typography and buttons are appropriately sized across flagship devices without data tracking in 2026.
Is this display identifier tool private?
Yes. All calculations and hardware detection happen 100% client-side in your browser. No data about your screen, viewport, or environment is ever sent to a server in 2026.
How do I test different viewports locally?
You can use Browser DevTools to emulate different devices, or simply resize your browser window while observing the zero-latency updates in our identification engine locally in 2026.
