Markdown: https://www.toolnova.org/diagnostics-tools/ip-address-lookup.md ## FAQ ### How accurate is the browser-based FPS counter? Our FPS Forge uses the High Resolution Time API and requestAnimationFrame nodes to measure exactly how many frames your GPU is rendering within the browser's execution context. ### Why is my refresh rate showing 60Hz on a 144Hz monitor? This diagnostic node detects the current synchronization between your OS and Browser. If it shows 60Hz, you may need to adjust your 'Display Advanced Settings' in your OS or check if your browser's hardware acceleration is enabled. ### Does the Speed Test track my IP address? No. Unlike traditional speed tests, ToolNova's Network Node performs a transient data transfer to measure velocity and latency without logging your geolocation or IP telemetry. ### Is this diagnostic tool suitable for professional IT troubleshooting? Yes. IT professionals use these tools as a fast, no-install diagnostic layer. The speed test measures ping, jitter, download, and upload throughput. The refresh rate test confirms whether monitors are running at their rated Hz. All results are displayed in real time with no software to deploy. ### Can I test my monitor for dead pixels or screen tearing? The Refresh Rate Test includes UFO tracking animations at multiple framerates that visually expose screen tearing. While we don't have a dedicated dead pixel tester, the full-screen visualizations can help you spot display artifacts. ### Does the CPS Test work with any mouse? Yes, it uses standard PointerEvent APIs that work with any pointing device. However, your results are affected by your mouse's polling rate and debounce time. Gaming mice (Razer, Logitech G, Zowie) with 1000Hz polling and low debounce will register more clicks than a standard office mouse. --- ToolNova — https://www.toolnova.org · See https://www.toolnova.org/llms.txt for the full directory.
