Parpadeo de Pantalla / PWM (Pulse-Width Modulation)
| Parpadeo de Pantalla / PWM detectado | 21000 Hz | ≤ 90 % de brillo |  |
La retroiluminación del display parpadea a 21000 Hz (seguramente usa PWM - Pulse-Width Modulation) a un brillo del 90 % e inferior. Sobre este nivel de brillo no debería darse parpadeo / PWM. La frecuencia de 21000 Hz es bastante alta, por lo que la mayoría de gente sensible al parpadeo no debería ver parpadeo o tener fatiga visual. Comparación: 53 % de todos los dispositivos testados no usaron PWM para atenuar el display. Si se usó, medimos una media de 8743 (mínimo: 5 - máxmo: 343500) Hz. | |||

Pro
Contra
El Lifebook E746 es un sólido portátil business. Ofrece a los compradores una amplia gama de puertos y muchas opciones de expansión. Sin embargo, las configuraciones disponibles van un poco rezagadas con respecto a los desarrollos técnicos más recientes, ya que Fujitsu no ofrece ningún procesador reciente.
Fujitsu ofrece a los compradores un portátil business caro pero muy adaptable - el Lifebook E746.
La relación precio-rendimiento es otro punto en contra del Lifebook E746. Muchos fabricantes ofrecen dispositivos con mejor hardware y una gama similar de puertos a un precio significativamente más bajo.
