诊断协议与流程
如何进行屏幕测试 (01, 02, 03)
01
准备工作
清洁显示器表面灰尘，关闭环境光自动感应，并将屏幕设置为原生分辨率与最高刷新率。
02
开始执行
进入全屏模式 (F11)，利用诊断控制栏依次切换并观察各种专业测试图案。
03
结果评估
在暗室环境下从不同视角细致观察屏幕均匀度、坏点与拖影，参考工程指南判断面板品质。

Technical FAQs & Helpful Content
Frequently Asked Questions (Keyboard Polling Rate (Hz) & Report Frequency Benchmark)
关于此项诊断工具、校准步骤及显示器技术标准所需了解的一切。
01.What is keyboard polling rate (Hz)?
Polling rate measures how many times per second (Hz) your keyboard sends input report packets to your computer.
02.What is the difference between 125Hz, 500Hz, 1000Hz, and 8000Hz?
125Hz = 8ms delay; 500Hz = 2ms delay; 1000Hz = 1ms delay; 8000Hz = 0.125ms delay.
03.How do I test my keyboard polling rate online?
Press and hold any key on your keyboard; the test calculates microsecond report deltas and displays real-time Hz.
04.Why is my 1000Hz keyboard showing lower Hz online?
Keyboards send reports when keys state changes; continuous holding or OS repeat rates determine incoming packet frequency.
05.Does an 8000Hz polling rate increase CPU usage?
Yes, 8000Hz generates 8,000 interrupts per second, requiring a high-performance multi-core CPU.
06.Can web browsers accurately measure 1000Hz polling rates?
Modern browsers (Chrome/Edge) with microsecond performance.now() timers process high-frequency HID report packets.
07.What is polling jitter?
Jitter measures variance between report arrival intervals; lower jitter indicates a stable USB connection.
08.Does USB 2.0 vs USB 3.0 affect keyboard polling rate?
Standard 1000Hz operates on USB 2.0; 4000Hz and 8000Hz high-rate keyboards require USB 3.0+ ports.
09.What is keyboard stability score?
Stability score (%) evaluates inter-report consistency and flags dropped or delayed USB packets.
10.How do I export my polling rate benchmark?
