Screen Resolution Tester
Check screen, viewport, pixel ratio, and color depth. Your work stays on this device whenever possible.
How to use Screen Resolution Tester
- Choose or enter the task, timer, note, or device information shown on the page; avoid using your only copy of important material.
- Start with content whose expected result you already know. Read every label and change only the settings relevant to this job.
- Run Screen Resolution Tester, then wait for its status message instead of pressing the action repeatedly.
- Adjust one option at a time so you can tell which setting changed the output. Save or copy the result only after that review.
What Screen Resolution Tester does
Check screen, viewport, pixel ratio, and color depth. The page concentrates on this exact job, keeps the controls beside the result, and reports invalid or incomplete input instead of silently inventing an answer.
The workflow runs on this device. Where a tool remembers state, it uses this browser’s local storage rather than a ToolkitPoint account. For Screen Resolution Tester, the operation is specifically to check screen, viewport, pixel ratio, and color depth.
Worked example
On a 1920 x 1080 display at 125% scaling, CSS viewport dimensions can be smaller while device-pixel ratio is above 1; both are displayed with live updates on window resize.
How to verify the result
Try the primary action and the reset or remove action before relying on the tool during important work. The final Screen Resolution Tester output should visibly match this goal: Check screen, viewport, pixel ratio, and color depth.
Important limitations
Browser zoom levels, OS display scaling, window borders, and multi-monitor configurations affect CSS viewport calculations relative to physical hardware resolution.
