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
23.2 ms ... rise ↗ and fall ↘ combined↗ 12.4 ms rise
↘ 10.8 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 0.1 (minimum) to 240 (maximum) ms. » 49 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21 ms).
       Response Time 50% Grey to 80% Grey
36 ms ... rise ↗ and fall ↘ combined↗ 16.4 ms rise
↘ 19.6 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. » 46 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (32.9 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 not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8774 (minimum: 5 - maximum: 343500) Hz was measured.

In review: Fujitsu Lifebook U747. Review sample courtesy of Fujitsu Germany.

O Lifebook U747 é um bom portátil. A Fujitsu dificilmente comete erros. Ele oferece uma excelente tela, boas durações da bateria, e um teclado que permite uma digitação confortável. A carcaça é estável, bem construída, e o seu design combina com o campo empresarial. Isto também pode ser dito sobre a diversidade das interfaces. Embora o Thunderbolt 3 não esteja instalado, isto seria mais um problema de luxo do que um verdadeiro ponto negativo. As temperaturas do modelo de teste permanecem sempre baixas e a ventoinha quase sempre está inativa.

O qual resulta em uma breve lista de desvantagens: Embora a ventoinha seja relativamente silenciosa, ela produz um ruído de alta frequência quando começa a funcionar. Certamente, este não é um motivo para sua exclusão, mas é perturbante. O mesmo acontece com os alto falantes e a webcam instalada. No entanto, não é habitual que estes componentes sejam um pouco ignorados. A maior desvantagem é o substituto do mouse. A Fujitsu não instala um touchpad Precision e por isso é um pouco ultrapassado - e o touchpad, portanto, não é tão bom quanto poderia ser. Infelizmente, as teclas do touchpad também deixam uma impressão muito inferior e imprecisa. Um TrackPoint que poderia ter compensado pelo touchpad não é instalado no Lifebook. Finalmente, o período de garantia é um pouco curto, em comparação com os concorrentes.

A Fujitsu envia um forte participante para competir pela coroa empresarial com o seu Lifebook U747. Infelizmente, o touchpad nada ideal, estraga a boa apresentação do poli funcional empresarial.

Apesar do touchpad, o Lifebook recebe uma recomendação de compra, dado que, no geral, é um aparelho bem concebido. No entanto, a concorrência não facilitará as coisas para a Fujitsu, dado que este setor do mercado é muito competitivo. Um rical muito forte, certamente é o Lenovo ThinkPad T470 que se sai melhor que o Lifebook em muitos aspectos; apenas su atela poderia se considerar pior. O novo Dell Latitude e os novos modelos Elitebook da HP (Latitude 7480 e Elitebook 840 G4) com certeza serão rivais fortes. Os testes correspondentes serão publicados em breve.
