What is my screen resolution?
This page instantly shows your screen resolution (for example 1920 × 1080), the real physical pixels on high-DPI displays, the size of your browser window (viewport), the device pixel ratio, colour depth, orientation, aspect ratio and an estimate of your refresh rate (60 Hz, 120 Hz, 144 Hz…).
Web designers use it to test responsive layouts, and gamers use it to check their monitor’s refresh rate.
