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
18 ms ... rise ↗ and fall ↘ combined↗ 14 ms rise
↘ 4 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 10 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (26.7 ms).
       Response Time 50% Grey to 80% Grey
45 ms ... rise ↗ and fall ↘ combined↗ 27 ms rise
↘ 18 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. » 68 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (42.8 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 1000 Hz90 % brightness setting

The display backlight flickers at 1000 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 1000 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 57 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 6272 (minimum: 43 - maximum: 142900) Hz was measured.

O HP EliteBook 755 G4 é um portátil empresarial no formato de 15 polegadas. O processador AMD é suficiente para os usos previstos, embora também tenha algumas desvantagens. Além disso, o portátil fornecido está equipado com 8 GB de RAM DDR4 e um veloz SSD de 256 GB no formato M.2-2280 e pode ser adquirido atualmente por 1460 Euros (~ $1650). Gostamos muito do acabamento limpo que não mereceu qualquer reclamação. Nós também gostamos do visual que parece muito discreto e elegante. Graças à seleção de bons materiais, a base é muito estável e, portanto, bastante adequada para uso diário. 

O HP EliteBook 755 G4 é um bom aparelho empresarial que traz muitos recursos de segurança em um aparelho de nível de entrada. Com o HP EliteBook 755 G4, qualquer pessoa para quem o desempenho do processador AMD seja suficiente recebe um bom aparelho de trabalho equipado com conexões modernas.

Nossas queixas mais fortes vão para a tela, que o torna um pacote menos completo. A qualidade simplesmente não combina com a série EliteBook. O fabricante deve verificar se esse nível de qualidade faz justiça ao objetivo real. Outra reclamação resulta do processador um pouco voraz, que resulta em uma duração curta da bateria.

Estamos um pouco divididos sobre a falta de uma escotilha de manutenção, dado que a parte inferior da carcaça pode ser removida com um pouco de tempo. Uma escotilha de manutenção seria mais amigável para o cliente em nossa opinião. Nós gostamos da qualidade do som, do teclado e do SSD rápido que beneficiam mais o sistema.
