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↗ 18 ms subida
↘ 2 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. » 20 % de todos los dispositivos son mejores.
Esto quiere decir que el tiempo de respuesta medido es mejor que la media (25.4 ms) de todos los dispositivos testados.
       Tiempo de respuesta 50% Gris a 80% Gris
4 ms ... subida ↗ y bajada ↘ combinada↗ 2 ms subida
↘ 2 ms bajada
La pantalla mostró tiempos de respuesta muy rápidos en nuestros tests y debería ser adecuada para juegos frenéticos.
En comparación, todos los dispositivos de prueba van de ##min### (mínimo) a 636 (máximo) ms. » 1 % de todos los dispositivos son mejores.
Esto quiere decir que el tiempo de respuesta medido es mejor que la media (40.7 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 250 Hz ≤ 100 % de brillo

La retroiluminación del display parpadea a 250 Hz (seguramente usa PWM - Pulse-Width Modulation) a un brillo del 100 % e inferior. Sobre este nivel de brillo no debería darse parpadeo / PWM.

La frecuencia de 250 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: 52 % de todos los dispositivos testados no usaron PWM para atenuar el display. Si se usó, medimos una media de 9705 (mínimo: 43 - máxmo: 142900) Hz.

Samsung Galaxy Book 12 LTE - modelo de pruebas cortesía de Samsung Alemania.
Samsung Galaxy Book 12 LTE - modelo de pruebas cortesía de Samsung Alemania.

Los posibles compradores con bastante dinero suelto dificilmente podrán equivocarse con el Samsung Galaxy Book 12 LTE si les gusta la idea de conectar un teclado y de alta portabilidad. Aparte de la magra selección de puertos, Samsung ha logrado combinar lo mejor de dos mundos en un dispositivo.

S-Pen y cubierta teclado vienen incluidas en la caja y rinden tan bien como el tablet bien diseñado y perfectamente fabricado.

Aunque el display Super-AMOLED no es perfecto, puede verse como un gancho comercial único del nuevo convertible Samsung con su valor de negro genial y su elevado contraste. Nuestro modelo de pruebas era un dispositivo LTE y cumplió con todos los requisitos de portabilidad, incluyendo GPS/GLONASS, TPM, BitLocker en Windows 10 Pro y un aguante de batería genial. Los usuarios ofimáticos estarán encantados con la flexibilidad de posición y buenos dispositivos de entrada mientras que la calidad de las cámaras implica que son algo más que un extra atractivo.

El hecho de que Samsung haya elegido un sistema de ventilación quedo y temperaturas de carcasa aceptables frente al rendimiento completo bajo carga contínua no debería notarse siempre que el dispositivo se use para lo que se pensó - como un dispositivo de oficina. Por ello, recomendaríamos definitivamente la compra de este dispositivo.
