Technical FAQs & Helpful Content
診断ツール＆ディレクトリ よくある質問 (FAQ)
この診断機器、校正手順、ディスプレイ技術規格について知っておくべきすべての情報。
01.What online diagnostic tools are available on Display Test Online?
Display Test Online provides over 40 free, browser-native diagnostic instruments covering screen display testing, mechanical keyboard switch chatter analysis, mobile touch digitizer matrices, hardware latency benchmarks, and US micro-utility calculators.
02.Are any software downloads or drivers required to use these tools?
No. 100% of our diagnostic tools run natively inside your browser using client-side WebGL, Canvas 2D, and Web Audio APIs. Zero downloads or plugin installations required.
03.How do I test my screen for dead pixels and backlight bleed?
Navigate to our Dead Pixel Inspector or OLED Uniformity tool, press F or tap Fullscreen, and cycle through solid RGB, pure black, and pure white color canvases in a dark room.
04.How does the Mechanical Keyboard Switch Chatter analyzer work?
Our keyboard diagnostic suite logs microsecond timestamp deltas between key release and immediate re-press. Timestamp deltas below 35ms trigger switch chatter double-typing warnings.
05.Can I generate a cryptographic Hardware Passport certificate?
Yes. Running our visual and peripheral tests compiles GPU renderer string, refresh rate stability, and input latency telemetry into an immutable, SHA-256 signed Hardware Passport receipt.
06.What is the 540Hz+ VRR Stutter & Tearing Sweep Engine?
Our VRR engine measures microsecond requestAnimationFrame (rAF) frame interval deltas to detect VSync, G-Sync, and FreeSync frame pacing stutter on high-refresh-rate gaming monitors up to 540Hz+.
07.How do the US Micro-Utility Calculators work?
Calculators like PC Bottleneck, EIA Appliance Energy, TV Distance, Wire Gauge, and 3D Print Cost use transparent engineering formulas and official government/industry datasets to provide instant sizing and cost benchmarks.
08.Are the touch screen diagnostic tools compatible with iPad, iPhone, and Android?
Yes. Our multi-touch and touch matrix tools track up to 10+ simultaneous finger touches, contact pressure, pointer IDs, and digitizer Root-Mean-Square (RMS) vector line noise.
09.Does Display Test Online collect or store my personal keystrokes or data?
No. All test execution, keystroke processing, and visual rendering happen locally within your browser sandbox. We collect zero personal input data.
10.How do I embed a live Hardware Passport badge on my tech blog or forum?
Use our embeddable iframe widget endpoint (/embed/passport) to display live, responsive hardware certification badges directly on your website or forum signature.
