Comprehensive Hardware Diagnostics Guide

Unlike traditional software that requires installation, DigiPandai utilizes advanced web APIs (WebGPU, WebNN, OPFS, Web Workers) to communicate directly with your device hardware. This ensures safety, privacy, and speed.

Technician's Analysis Guide

CPU Benchmark Reading

Our benchmark runs a prime-counting workload across all logical cores using Web Workers. A large gap between "Single-Core" and "Multi-Core" scores usually means the workload benefits heavily from more threads — useful for video editing or compiling.

RAM Health Check

If allocation of a large typed array fails or throws an error, your browser tab may be memory-constrained. Compare the reported Device Memory against the "Allocation Speed" result to detect abnormal slowdowns.

Storage Speed Analysis

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.

Printer Calibration

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.

Monitor Refresh Rate

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.

Color Gamut & HDR

Not every "HDR" monitor is created equal. Our Display & Color tool checks your browser's reported color-gamut (srgb/p3/rec2020) and dynamic-range capability so you know if HDR content will actually render as intended.

Frequently Asked Questions

How accurate is the CPU Benchmark?
The CPU Benchmark measures relative throughput using a standardized prime-counting workload spread across Web Workers. It's designed for quick comparisons between devices and browsers rather than as a replacement for dedicated native benchmarking suites.
Is the Printer Test Page free?
Yes, the calibration sheet is generated client-side in your browser. It includes CMYK blocks, gradients, and alignment grids to test printer health without wasting ink on heavy images.
Why does the screen go black during the Pixel Test?
This is intentional to help you spot stuck pixels (dots that stay red, green, or blue) or dead pixels (black dots). The interface hides itself after 3 seconds so you can focus on the screen.
Is my hardware data sent to a server?
No. DigiPandai operates entirely client-side. All diagnostics (Camera, Mic, Storage, Sensors, CPU, RAM) run locally within your browser using Web APIs. No personal data or hardware fingerprints are uploaded to our servers, ensuring your privacy.
Why is my Refresh Rate (Hz) stuck at 60Hz on mobile?
Many smartphones automatically limit the refresh rate to 60Hz when "Power Saving Mode" is active to save battery. Try disabling power saver or plugging in your charger to unlock your screen's maximum Hz (90Hz/120Hz).
Why doesn't the Storage Benchmark work on my iPhone?
The Storage Benchmark uses the OPFS (Origin Private File System) API, which requires modern browser support. On iOS, ensure you are updated to iOS 15.2 or later. If using a WebView (inside apps like Instagram/TikTok), open this page in Safari or Chrome for full functionality.
Why can't I scan Bluetooth or USB devices on my phone?
Web Bluetooth and WebUSB are currently only supported on Chromium-based desktop and Android browsers (Chrome, Edge, Opera). Safari and Firefox do not expose these APIs for security reasons, so the scanner will report "Not Supported" there.
