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
20 ms ... rise ↗ and fall ↘ combined↗ 9.2 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 0.8 (minimum) to 240 (maximum) ms. » 13 % 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
39.2 ms ... rise ↗ and fall ↘ combined↗ 20.4 ms rise
↘ 18.8 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. » 42 % 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 211.9 Hz20 % brightness setting

The display backlight flickers at 211.9 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 20 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 211.9 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 57 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 6285 (minimum: 43 - maximum: 142900) Hz was measured.

Review: Fujitsu LifeBook U937. Test unit provided by Fujitsu

Gostamos do Fujitsu LifeBook U937. Além do minúsculo touchpad e da falta de iluminação de fundo do teclado, os poucos pontos de crítica que temos são apenas coisas menores que não têm um grande impacto no desempenho geral; o pequeno companheiro empresarial não possui fraquezas reais.

Sim, a tela poderia ter melhor distribuição do brilho e o ruído da ventoinha de resfriamento pode incomodar usuários sensíveis. Mas o SSD SATA III também pode ser trocado por uma versão PCIe  e as pequenas ventoinhas soam igual à maioria dos aparelhos comparados.

Por outro lado, há muitos aspectos positivos deste dispositivo: em primeiro lugar, o peso incrivelmente leve de 950 g (~2,1 lb) e seu tamanho compacto. Ele também possui muitos recursos de segurança e muito boas durações da bateria. Outro bônus é que é fácil de reparar e expandir. O aparelho é especialmente adequado como um portátil empresarial (smart card), mas também pode agradar aos usuários particulares.

Por pouco menos de $1500, você receberá um portátil empresarial muito pequeno e provavelmente o mais leve, com muitos recursos de segurança, boas durações da bateria e uma tela brilhante. Nós definitivamente recomendamos o U937. Ele tem apenas algumas pequenas fraquezas e se desempenha brilhantemente em muitos aspectos.
