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
31.2 ms ... rise ↗ and fall ↘ combined↗ 17.2 ms rise
↘ 14 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 80 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (26 ms).
       Response Time 50% Grey to 80% Grey
22.4 ms ... rise ↗ and fall ↘ combined↗ 10.8 ms rise
↘ 11.6 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 8 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (41.6 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: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 10727 (minimum: 43 - maximum: 588200) Hz was measured.

Tudo considerado, ficamos bastante contentes com o ZenBook 13 UX331UN. Ele possui uma tela de alta qualidade e alto-falantes surpreendentemente decentes, que são os principais ingredientes de um portátil multimídia que pode ser usado ao ar livre graças ao seu impressionante brilho máximo na tela. Além disso, a combinação de CPU e GPU é suficientemente poderosa para rodar jogos sem problemas com resoluções e detalhes reduzidos. Como tal, o ZenBook é literalmente um exemplo  de um verdadeiro poli funcional. É fino e leve, apresenta uma carcaça de alta qualidade, um touchpad muito bom, e permanece frio a maior parte do tempo. Além disso, a duração da bateria é excelente, apesar da bateria de 50 Wh.

Combinados, esses são alguns pontos positivos impressionantes. Infelizmente, o ZenBook ainda não é perfeito e tem uma série de falhas. O teclado é apenas regular, o sistema de resfriamento não é suficientemente poderoso, o desempenho da CPU é muito inconsistente e o processador tende se afogar muito rápido e muitas vezes (o que conseguimos confirmar no Cinebench R15 e nosso cenário de teste de estresse). Não sé ó isso, a CPU também é significativamente mais lenta quando funciona com a energia da bateria. E não esqueçamos o nível de ruído que o ZenBook emite sob uso intenso e ao rodar jogos. Na verdade, está no limite do irritante para o usuário mais sensível. Por último, mas não menos importante, o SSD SATA III integrado, a falta de Thunderbolt 3 e a porta USB-C extremamente limitada (sem suporte para DisplayPort) também são desvantagens dignas de mencionar.

Atraente: Em geral, a Asus conseguiu atingir o jackpot com o ZenBook 13 UX331UN em todos os lugares certos.

Os pros superam inequivocamente os contras, e é por isso que o ZenBook 13 UX331UN merece uma recomendação. Ao procurar um portátil com uma GPU discreta, é certamente uma alternativa maravilhosa para o Dell XPS 13.
