PROTOCOLO DE DIAGNÓSTICO

Como Executar Este Teste de Tela (01, 02, 03)

Preparação

Limpe a superfície do monitor, desative sensores de luz ambiente e defina a resolução e taxa de atualização nativas.

Execução

Entre no modo de tela cheia (F11) e use os controles para navegar pelos padrões de teste.

Avaliação

Observe anomalias de diferentes ângulos de visão em um ambiente escuro. Consulte nossos guias para interpretar os resultados.

ARQUITETURA DE HARDWARE

Comparativo de Tecnologias de Painel

IPS Profissional (In-Plane Switching)

Precisão de cores e ângulos de visão superiores. Usado em monitores de referência. Sujeito a leve brilho IPS no escuro.

IPS Gamer (Fast IPS / Nano IPS)

Altas taxas de atualização e tempos de resposta rápidos para jogos, porém contraste estático menor que o VA.

Painel VA (Alinhamento Vertical)

Excelentes pretos profundos e alto contraste (3000:1+). Comum em telas curvas. Pode apresentar black smearing em movimento rápido.

OLED (LED Orgânico) e QD-OLED

Pixels autoiluminados proporcionam preto puro, tempos de resposta quase instantâneos e contraste infinito. Sujeito a ABL.

Technical FAQs & Helpful Content

Frequently Asked Questions (Keyboard Polling Rate (Hz) & Report Frequency Benchmark)

Tudo o que você precisa saber sobre este instrumento de diagnóstico, procedimentos de calibração e normas técnicas.

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?
