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
23.2 ms ... subida ↗ y bajada ↘ combinada↗ 12.4 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. » 47 % 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
36 ms ... subida ↗ y bajada ↘ combinada↗ 16.4 ms subida
↘ 19.6 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. » 44 % de todos los dispositivos son mejores.
Eso quiere decir que el tiempo de respuesta es similar al dispositivo testado medio (33.9 ms).

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 no detectado

Comparación: 53 % de todos los dispositivos testados no usaron PWM para atenuar el display. Si se usó, medimos una media de 18110 (mínimo: 5 - máxmo: 3846000) Hz.

Análisis: Fujitsu Lifebook U747. Modelo de prueba cedido por Fujitsu Alemania.
Análisis: Fujitsu Lifebook U747. Modelo de prueba cedido por Fujitsu Alemania.

El Lifebook U747 es un buen portátil. Fujitsu apenas comete errores. Ofrece una soberbia pantalla, buena duración de batería y un teclado que permite un tecleo agradable. La carcasa es estable, bien construida, y su diseño encaja bien con lo que se espera de un portátil de negocios. Esto se puede decir también de la variedad de interfaces. A pesar de que no incluye Thunderbolt 3, esto no es realmente un punto negativo porque tampoco sería algo esperable. Las temperaturas del modelo de prueba siempre se han mantenido bajas y el ventilador casi siempre parado.

Esto nos lleva a la pequeña lista de inconvenientes: a pesar de que el ventilador se mantiene bastante en calma, produce un ruido de alta frecuencia cuando empieza a funcionar. Esto no es una razón para descartarlo, pero sí resulta molesto. Lo mismo ocurre con los altavoces y la webcam instalada. Sin embargo, no es inusual que estos componentes no reciban demasiada atención. El mayor inconveniente es el touchpad: Fujitsu no ha instalado un touchpad Precision, el incluido es un poco antiguo y por tanto no es tan bueno como podría haber sido. Desafortunadamente las teclas del touchpad solo empeoran esta impresión. Un TrackPoint podría haber compensado este problema, pero no se incluye ninguno. Finalmente el periodo de garantía es corto en comparación con sus competidores. 

Con el Lifebook U747 Fujitsu presenta un solido aspirante a la corona de portátiles para negocios. Desafortunadamente el mediocre touchpad arruina la buena presentación del portátil.

Despite the touchpad, the Lifebook receives a recommendation as it is overall well-conceived otherwise. However, the competition will not make it easy for Fujitsu as this market sector is highly competitive. A very strong rival is certainly Lenovo's ThinkPad T470 that scores better than the Lifebook in many aspects; only its screen is considerably worse. Dell's new Latitude and HP's new EliteBook models (Latitude 7480 and EliteBook 840 G4) will also surely be strong rivals. The corresponding tests will be published soon.

A pesar del touchpad, el Lifebook recibe nuestra recomendación por su nivel global. Sin embargo, la competencia no se lo pone fácil ya que este sector es muy competitivo. Un rival muy fuerte es el Lenovo's ThinkPad T470 que puntua mejor que el Liefbook en varios aspectos aunque su pantalla es bastante peor. El nuevo Latitude de Dell y el nuevo EliteBook de HP (Latitude 7480 y Elitebook 840 G4) son también potentes rivales. Los analizaremos pronto.
