Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
32 ms ... rise ↗ and fall ↘ combined↗ 18 ms rise
↘ 14 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 82 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25.9 ms).
       Response Time 50% Grey to 80% Grey
39 ms ... rise ↗ and fall ↘ combined↗ 20 ms rise
↘ 19 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 40 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (41.4 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 21000 Hz ≤ 90 % brightness setting

The display backlight flickers at 21000 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 21000 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8882 (minimum: 43 - maximum: 142900) Hz was measured.

Testing the HP EliteBook 755 G5. Test unit provided by HP Germany.

A HP oferece uma atualização de geração cultivada para os compradores do EliteBook 755 G5. O desempenho da CPU AMD Ryzen 7-2700U é bom, mas poderia ter sido ainda melhor com um resfriamento otimizado. A tampa inferior removível oferece aos usuários acesso ao interior, permitindo que eles executem tarefas de manutenção. A boa cobertura do espaço de cores é levemente diminuída pelo alto valor de preto e baixo contraste.

O HP EliteBook 755 G5 é um atraente portátil empresarial com desempenho suficiente também para tarefas mais exigentes e uma duração de bateria que dura um dia inteiro de trabalho.

Os usuários recebem um dispositivo que é apresentável com seu design atraente e oferece duração de bateria suficiente para um dia útil. O fato de que o consumo de energia é maior do que em outros dispositivos não tem consequências graves e, além disso, dificilmente há razões que falem contra a compra do HP EliteBook 755 G5.
