Display Response Times

ℹ

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
35 ms ... rise ↗ and fall ↘ combined	↗ 19 ms rise
35 ms ... rise ↗ and fall ↘ combined	↘ 16 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 92 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.9 ms).
↔ Response Time 50% Grey to 80% Grey
55 ms ... rise ↗ and fall ↘ combined	↗ 24 ms rise
55 ms ... rise ↗ and fall ↘ combined	↘ 31 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 91 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.8 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ

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

200 Hz

≤ 90 % brightness setting

The display backlight flickers at 200 Hz (worst case, e.g., 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 200 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8715 (minimum: 5 - maximum: 343500) Hz was measured.

Com o LifeBook A557 a Fujitsu possui um sistema muito atraente para o seu pequeno pedaço de mercado. O portátil de 15,6-polegadas convence principalmente com um sólido desempenho de sistema, que sustenta a sua implantação como um sistema de escritório. Até a data o Intel Core i5-7200U se tornou um processador comum que é muito capaz de lidar com tarefas mais complexas. Com 8 GB de RAM, nosso sistema está bem equipado. Se isso não for suficiente, pode ser expandido sem dificuldades, dado que as possibilidades de manutenção são exemplares no Fujitsu LifeBook A557. O SSD de 512 GB oferece muito armazenamento e contribui com um boa parte para a fluidez do sistema.

O Fujitsu LifeBook A557 oferece um bom desempenho para orçamento moderados. Aqueles que não dão muita importância ao design estarão contentes com o Fujitsu LifeBook A557.

Não conseguimos encontrar muitas falhas no Fujitsu LifeBook A557. Visualmente, nosso sistema de teste é bastante simples, e no futuro o fabricante poderia melhorar a poluição sonora. Também teríamos desejado um teclado iluminado. Mas com um preço de 649 Euros (~$682) deveríamos esperar o incômodo compromisso. Além disso, a tela oferece somente um a cobertura de cores limitada, embora seus ângulos de visão sejam convincentes. O Fujitsu LifeBook A557 também deixou uma impressão positiva com o seu baixo consumo de energia que, ao mesmo tempo, garante uma longa duração da bateria.

In review: Fujitsu LifeBook A557. Test model provided by Fujitsu Germany

With the LifeBook A557 Fujitsu has a very attractive system for the small pocket on the market. The 15.6-inch notebook convinces mainly with a solid system performance, which underpins its deployment as an office system. By now the Intel Core i5-7200U has become a common processor that is quite capable to take on also more complex tasks. With 8 GB of RAM, our system is well equipped. If that is not enough, it can be expanded without difficulties, since the maintenance possibilities are exemplary in the Fujitsu LifeBook A557. The 512 GB SSD offers a lot of storage and contributes a relevant share to the smooth running system.

The Fujitsu LifeBook A557 offers a decent performance for small purses. Those who do not place too much importance on the design will be happy with the Fujitsu LifeBook A557.

We cannot find much fault in the Fujitsu LifeBook A557. Visually, our test system is rather unspectacular, and in the future the manufacturer could improve on the noise pollution. We also would have wished for an optional backlit keyboard. But with a price tag of 649 Euros (~$682) we should expect the odd compromise. Furthermore, the display offers only a limited color space coverage, although its viewing angles are convincing. The Fujitsu LifeBook A557 also left a positive impression with its low power consumption that in turn assures a long battery life.
