Tiempos de respuesta del display

Los tiempos de respuesta del display muestran lo rápido que puede cambiar la pantalla de un color al siguiente. Tiempos lentos de respuesta pueden llevar a imágenes persistentes alrededor de objetos en movimiento o a displays borrosos. Particularmente los aficionados a los juegos 3D frenéticos deberían usar una pantalla con tiempos de respuesta rápidos.
       Tiempo de respuesta de Negro a Blanco
20 ms ... subida ↗ y bajada ↘ combinada↗ 9.2 ms subida
↘ 10.8 ms bajada
La pantalla mostró buenos tiempos de respuesta en nuestros tests pero podría ser demasiado lenta para los jugones competitivos.
En comparación, todos los dispositivos de prueba van de ##min### (mínimo) a 240 (máximo) ms. » 37 % de todos los dispositivos son mejores.
Eso quiere decir que el tiempo de respuesta es similar al dispositivo testado medio (21.6 ms).
       Tiempo de respuesta 50% Gris a 80% Gris
39.2 ms ... subida ↗ y bajada ↘ combinada↗ 20.4 ms subida
↘ 18.8 ms bajada
La pantalla mostró tiempos de respuesta lentos en nuestros tests y podría ser demasiado lenta para los jugones.
En comparación, todos los dispositivos de prueba van de ##min### (mínimo) a 636 (máximo) ms. » 54 % de todos los dispositivos son mejores.
Eso quiere decir que el tiempo de respuesta es peor que la media (33.9 ms) de todos los dispositivos testados.

Parpadeo de Pantalla / PWM (Pulse-Width Modulation)

Para atenuar el brillo de pantalla algunos portátiles están encendiendo y apagando la retroiluminación muy rápidamente. Esto se hace a una frecuencia que no debiera detectarse a simple vista. Si la frecuencia es demasiado lenta, la gente sensible podría experimentar problemas visuales, dolores de cabeza e incluso ver parpadeos.
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 18071 (mínimo: 5 - máxmo: 3846000) Hz.

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.
