Screen resolution: screen.width x screen.height (physical pixels). Viewport: window.innerWidth x window.innerHeight (CSS pixels). Device pixel ratio (DPR): window.devicePixelRatio. Physical pixels = CSS pixels * DPR. A 1440x900 screen at 2x DPR reports as 2880x1800 physical but 1440x900 CSS. Color depth: screen.colorDepth (typically 24-bit = 16.7M colors).
