Display Response Comparison · At a glance
Quick answer: Compare visual reaction rounds on different displays under the same conditions. The median can support a subjective setup comparison, but human response variation remains part of every sample.
Display Response Comparison
The test loads when you open it. Device access is requested only after you choose to start.
Detailed guide
How to use this tool
- Complete visual reaction rounds on each display using the same input device.
- Keep refresh settings and test conditions fixed.
Input
Visual or auditory cue, followed by input
Browser requirement
Animation timing; Web Audio for sound cues
Processing
Runs on your device; no tool-result upload
How it works and what the result means
The displayed time includes your reaction, browser scheduling and input/display or audio delay. It cannot isolate the physical latency of a monitor or mouse.
Reading the result
The median can support a subjective setup comparison, but human response variation remains part of every sample.
What to check next
Use several attempts and avoid comparing a familiar run with an unpracticed one. Keep the display in the same picture mode.
An early input ends that attempt. Restart and wait for the cue. Compare medians on the same browser with background workloads closed.
Frequently asked questions
Can I subtract two scores to obtain exact display lag?
No. Human and scheduling variation prevent an exact isolation. A dedicated simultaneous-display or optical method is needed for precise panel lag.
How do I start the Display Response Comparison?
Start a round and wait without pressing. React only after the color changes or the sound plays. Complete several attempts to see the median.
Does this tool require a download or an account?
No. Open the interactive tool above in a modern browser. The instructions and explanations are available even with JavaScript disabled; running a test needs JavaScript.
Why can two attempts give different results?
Power settings, background tasks, browser scheduling, operating-system input processing and device settings affect measurements. Compare repeated attempts with identical settings rather than the single highest score.
