Parpadeo de Pantalla / PWM (Pulse-Width Modulation)
| Parpadeo de Pantalla / PWM detectado | 211.9 Hz | ≤ 20 % de brillo |  |
La retroiluminación del display parpadea a 211.9 Hz (seguramente usa PWM - Pulse-Width Modulation) a un brillo del 20 % e inferior. Sobre este nivel de brillo no debería darse parpadeo / PWM. La frecuencia de 211.9 Hz es relativamente baja, por lo que la gente sensible debería ver parpadeos y padecer fatiga visual por la pantalla (usado al brillo indicado a continuación). Comparación: 53 % de todos los dispositivos testados no usaron PWM para atenuar el display. Si se usó, medimos una media de 8746 (mínimo: 5 - máxmo: 343500) Hz. | |||

Pro
Contra
Nos gustó el Fujitsu LifeBook U937. Aparte del touchpad malo y la falta de retroiluminación del teclado, los pocos puntos de crítica que tenemos son sólo cosas menores que no tienen un gran impacto en el rendimiento general; el pequeño compañero business no tiene debilidades reales.
Sí, la pantalla podría tener una mejor distribución del brillo y el ruido del ventilador podría molestar a los usuarios sensibles. Pero el SSD SATA III también se puede cambiar para una versión PCIe y los ventiladores de enfriamiento pequeños suenan igual en la mayoría de los dispositivos de comparación.
Por otro lado, hay muchos aspectos positivos de este dispositivo: en primer lugar, el peso increíblemente ligero de 950 g y su tamaño compacto. También tiene un montón de características de seguridad y muy buen tiempo de duración de la batería. Otra ventaja es que es fácil de reparar y ampliar. El dispositivo es especialmente adecuado como un portátil business (tarjeta inteligente), pero también podría satisfacer a los usuarios domésticos.
Por poco menos $1500, puedes comprar un portátil business muy pequeño y probablemente el más ligero con un montón de características de seguridad, un buen tiempo de duración de la batería y un display brillante. Sin duda recomendamos el U937. Sólo tiene algunas debilidades menores y rinde espectacularmente en muchos aspectos.
