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 1064 Hz ≤ 90 % de brillo

La retroiluminación del display parpadea a 1064 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 1064 Hz es bastante alta, por lo que la mayoría de gente sensible al parpadeo no debería ver parpadeo o tener fatiga visual.

Comparación: 51 % de todos los dispositivos testados no usaron PWM para atenuar el display. Si se usó, medimos una media de 9566 (mínimo: 43 - máxmo: 142900) Hz.

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
34.4 ms ... subida ↗ y bajada ↘ combinada↗ 17.2 ms subida
↘ 17.2 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 240 (máximo) ms. » 89 % de todos los dispositivos son mejores.
Eso quiere decir que el tiempo de respuesta es peor que la media (25.3 ms) de todos los dispositivos testados.
       Tiempo de respuesta 50% Gris a 80% Gris
48 ms ... subida ↗ y bajada ↘ combinada↗ 24.4 ms subida
↘ 23.6 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. » 77 % de todos los dispositivos son mejores.
Eso quiere decir que el tiempo de respuesta es peor que la media (40.4 ms) de todos los dispositivos testados.

El Precision 3520 definitivamente tiene puntos positivos. En primer lugar la pantalla, que muestra colores vivos y es brillante. La duración de batería es muy buena para una estación de trabajo y debe ser impresionante con la opción de 92 Wh. El número de puertos es suficiente. El chasis y los dispositivos de entrada son suficientemente buenos para una máquina de negocios, pero no perfectos.

Desafortunadamente el Precision falla respecto a lo más importante para una estación de trabajo: rendimiento y nivel de ruido. La restricción a un TDP de 35 W resulta sorprendente - Dell probablemente debería buscar un sistema de refrigeración más sofisticado, aunque no podemos olvidar que estamos ante una estación de trabajo de bajo precio. Nos preguntamos si no habría sido mejor elección una CPU con un consumo más bajo. Nuestro test de estrés revela que el rendimiento puede variar mucho bajo carga, como si el firmware realizase algún tipo de ajustes. Desafortunadamente, esto ocurre también con el control de ventilador, ya que en ocasiones se activa sin motivo aparente. Tras las pruebas, el ventilador tardó mucho en desactivarse de nuevo. Además el 3520 emite un ruido electrónico.

The Precision 3520 es una estación de trabajo solida - pero podría mejorar en varios aspectos.

En resumen podemos decir que el Precision 3520 tiene potencial. El portátil es muy potente y tiene un buen ratio precio-rendimiento. Al fin y al cabo las estaciones de trabajo pueden ser muy caras. De todas formas Dell necesita replantearse el control del ventilador y mejorar el rendimiento. En cuanto eso ocurra, el 3520 será una buena recomendación de compra.
