Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
29.2 ms ... rise ↗ and fall ↘ combined↗ 16 ms rise
↘ 13.2 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 76 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21 ms).
       Response Time 50% Grey to 80% Grey
44.8 ms ... rise ↗ and fall ↘ combined↗ 22.8 ms rise
↘ 22 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 74 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (32.9 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8774 (minimum: 5 - maximum: 343500) Hz was measured.

Quanto desempenho precisa um dispositivo móvel? Os dispositivos finos geralmente têm problemas para utilizar o potencial de desempenho dos atuais processadores quad-core móveis. No entanto, as tarefas diárias normalmente não precisam desse nível de desempenho. Nós gostamos da abordagem com um Modo Silencioso adicional, que é mais abrangente em comparação com as configurações de energia do Windows regulares ou o controle deslizante de desempenho, respectivamente.

O novo ZenBook S UX391 da Asus é extremamente móvel e tem como alvo clientes que frequentemente estão na estrada e precisam de um dispositivo compacto. Aplicativos muito complexos geralmente não estão no topo da lista de requisitos e, na maioria das vezes, serão usados para escrever e-mails, usar aplicativos baseados na nuvem ou apenas usar o pacote do Office. O desempenho do ZenBook S é mais do que suficiente para esses cenários, mesmo quando você ativa o modo silencioso.

O ZenBook S UX391 é uma muito boa escolha se você deseja um companheiro muito leve e compacto. No entanto, alguns dos rivais podem utilizar melhor o desempenho do quad-core ULV e durar mais com a bateria. 

Você também obtém um dispositivo de alta qualidade com um chassi de metal e boa qualidade de construção.  Gostamos da tela mate de 1080p, embora possa ser um pouco mais brilhante e melhor calibrada, de fábrica. Os dispositivos de entrada são decentes e a Asus implementa portas modernas. Uma pequena estação docking adiciona portas tradicionais e está incluída.

Já mencionamos o desempenho medíocre acima. Se você precisa de mais desempenho em um chassi compacto, você deve procurar outro modelo. Caso contrário, podemos recomendar o ZenBook S UX391.
