| 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. » 40 % of all devices are better.

| 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. » 56 % 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)
| Screen flickering / PWM detected | 211.9 Hz | ≤ 20 % brightness setting |  |
The display backlight flickers at 211.9 Hz (worst case, e.g., 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: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8705 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Pro
Contra
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.
