Parpadeo de Pantalla / PWM (Pulse-Width Modulation)
| Parpadeo de Pantalla / PWM detectado | 200 Hz | ≤ 90 % de brillo |  |
La retroiluminación del display parpadea a 200 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 200 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 8705 (mínimo: 5 - máxmo: 343500) Hz. | |||

Con el LifeBook A557 Fujitsu tiene un sistema muy atractivo para el pequeño bolsillo. El portátil de 15.6" convence principalmente con un rendimiento sólido, que apuntala su uso como sistema de oficina. Por ahora la Intel Core i5-7200U se ha vuelto un procesador común que es casi capaz de habérselas con tareas más complejas. Con 8 GB de RAM, nuestro sistema está bien equipado. Si eso no basta, se puede ampliar sin dificultades, ya que las posibilidades de mantenimiento son ejemplares en el Fujitsu LifeBook A557. El SSD de 512 GB ofrece mucho almacenamiento y contribuye en gran parte a que el sistema vaya fluido.
El Fujitsu LifeBook A557 ofrece un rendimiento decente para bolsillos pequeños. Los que no le den mucha importancia al diseño quedarán satisfechos con el Fujitsu LifeBook A557.
No podemos encontrarle muchos defectos al Fujitsu LifeBook A557. Visualmente, nuestro sistema de pruebas no es nada espectacular, y en el futuro el fabricante podría mejorar las emisiones de ruido. También nos habría gustado un teclado iluminado opcional. Pero con un precio de 649 Euros, deberíamos esperar algún sacrificio. Lo que es más, el display ofrece sólo una cobertura limitada del espacio de color, aunque sus ángulos de visión son convincentes. El Fujitsu LifeBook A557 también causó una impresión positiva con su bajo consumo de energía que, a cambio, asegura un gran aguante de batería.
