Detailed Overview
Screen Resolution and Display DPI Checker detects your screen's physical resolution, the browser viewport size, the device pixel ratio used for Retina-style scaling, the colour bit depth, and the current orientation, all in real time. It is useful when you are testing a responsive design, reporting a display bug, or checking whether a monitor is running at its native resolution.
To use it, open the tool and read the values, then resize the browser window to see the viewport figure change while the physical resolution stays put. That distinction matters: a page lays out against the viewport, not the full screen, so a layout bug that only appears in a narrow window will not show up in the physical resolution figure.
Check the browser zoom level before you compare readings. A zoomed browser reports a different viewport and an adjusted pixel ratio, so two people checking the same monitor can get different numbers if one of them is zoomed in. Reset zoom to 100 percent for a clean comparison, and note the operating system's display scaling, which also affects the reported values.
One honest limitation: these figures are what the browser reports, not a hardware measurement. The tool cannot calibrate your display, measure its true physical size, or confirm colour accuracy, so use it to inspect reported values and reproduce layout conditions, not as a display calibration instrument.
