Parpadeo de Pantalla / PWM (Pulse-Width Modulation)
| Parpadeo de Pantalla / PWM detectado | 198.4 Hz | ≤ 99 % de brillo |  |
La retroiluminación del display parpadea a 198.4 Hz (seguramente usa PWM - Pulse-Width Modulation) a un brillo del 99 % e inferior. Sobre este nivel de brillo no debería darse parpadeo / PWM. La frecuencia de 198.4 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. | |||

Contra
Los mejores aspectos del Miix 520 son su rendimiento de procesador, rendimiento de SSD, versatilidad de puertos y precio. Su ratio de rendimiento/dolar es uno de los mejores en el mercado actual, ya que otros tablets Windows aún tienen Core Y u otras opciones de la séptima generación. Los usuarios que quieran explotar los caballos adicionales de potencia encontrarán en el Miix 520 un buen pseudo-Ultrabook para viajar.
El resto de cosas del desmontable de Lenovo no son necesariamente malas o incluso promedio, pero definitivamente hay espacio para mejorar en comparación con algunas alternativas cercanas. Surface Pro y Elite x2 son más robustos en diseño, tienen pantallas más brillantes y de mayor resolución, colores más precisos y un mayor aguante de la batería. El tablet HP, en particular, también lleva Thunderbolt 3 para una gama aún más amplia de opciones de conectividad. Una base de teclado más firme para el Lenovo habría mejorado la experiencia de tecleo esponjoso en relación con los teclados en la mayoría de los Ultrabooks.
La desventaja más evidente de un procesador de alto rendimiento es el ruido del ventilador. El ventilador es un poco más ruidoso que el del Surface Pro y hará un ciclo mucho más frecuente durante el uso diario. No es tan fuerte como en la serie de convertibles HP Spectre, pero es, sin embargo, notable, especialmente para un formato tablet.
El Miix 520 es una gran compra siempre que los usuarios conozcan sus desventajas. El rápido rendimiento de la CPU viene con el costo de un ruido de ventilador más fuerte y más frecuente. Esperamos que en futuras revisiones actualicen la pantalla e incorporen Thunderbolt 3 para que la serie Miix sea aún más competitiva frente a Microsoft.
