Comprehensive Hardware Diagnostics Guide
Unlike traditional software that requires installation, DigiPandai utilizes advanced web APIs (WebGPU, WebNN, OPFS) to communicate directly with your device hardware. This ensures safety, privacy, and speed.
Technician's Analysis Guide
We utilize the Origin Private File System (OPFS) for accuracy. If your "Write Speed" is consistently under 50MB/s on a modern SSD, it may indicate storage degradation or background activity overload.
Use our "Pro Calibration Page" to detect clogged nozzles. Inspect the 6pt micro-text line at the bottom; if the text appears fuzzy or broken, perform a print head cleaning cycle immediately.
Gaming monitors often default to 60Hz in Windows/Android settings. Use the "Refresh Rate" tool to verify if your 144Hz/165Hz mode is actually active and detected by the browser.
