PC Diagnostic Lab — Browser Checks
Inspect screen resolution, browser capabilities, WebGL, connectivity indicators and media permissions. Clear limitations, no invented hardware diagnosis.
Browser capability checks
This page reports what your browser exposes. It cannot diagnose internal hardware faults or measure internet speed accurately without a test server.
How it works
Run the browser check to display the information your device voluntarily exposes to web pages. The report may include screen size, logical processors and WebGL availability, depending on browser restrictions.
Use the dedicated permission buttons if you need to verify whether this website may access your microphone or camera. Any temporary media stream is stopped immediately after the permission check.
For BSODs, failing hardware or Windows errors, use our PC troubleshooting guides and manufacturer diagnostics. Browser APIs cannot verify SSD health, RAM defects or your actual download speed.
Important limitations: Results are browser-provided indicators, not authoritative hardware benchmarks or security scans. Some details are hidden for privacy.
