Not a professional diagnosis
RatedTechTools provides informational self-tests. Results do not certify hardware condition, display calibration, hearing, electrical safety, network service quality, or fitness for a particular purpose. Consult a qualified technician or the manufacturer when the cost or safety impact of a decision is significant.
Measurement limits
Refresh-rate results estimate requestAnimationFrame cadence, not guaranteed panel Hz. The latency tool measures HTTPS request timing, not ICMP ping. Microphone levels are relative digital values, not calibrated acoustic dB SPL. Screen pixel dimensions can be affected by scaling and zoom.
Audio and visual safety
Keep speaker and headphone volume low before playing tones. The sound test is not a hearing examination. Avoid prolonged exposure to bright fullscreen patterns and stop immediately if a visual pattern causes discomfort.
