Screen resolution is the number of pixels displayed on your screen, measured as width × height (e.g., 1920×1080). Higher resolution means more detail.
Device Pixel Ratio (DPR) indicates how many physical pixels correspond to one CSS pixel. A DPR of 2 (like Retina displays) means 4 physical pixels per CSS pixel.
Viewport size is the visible area of your browser window (minus toolbars, scrollbars). Screen resolution is the full physical display size.
