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
26 ms ... rise ↗ and fall ↘ combined↗ 15 ms rise
↘ 11 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 0.8 (minimum) to 240 (maximum) ms. » 47 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (24.8 ms).
       Response Time 50% Grey to 80% Grey
36 ms ... rise ↗ and fall ↘ combined↗ 19 ms rise
↘ 17 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 30 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (39.3 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 detected 44 Hz ≤ 20 % brightness setting

The display backlight flickers at 44 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 20 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 44 Hz is very low, so the flickering may cause eyestrain and headaches after extended use.

In comparison: 50 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 18215 (minimum: 5 - maximum: 2500000) Hz was measured.

有了Asus ZenBook 14 UM431DA,购买它的人将获得设计出色的笔记本电脑,并且价格相对较低,且轻便。该外壳看起来非常高品质,各种装饰元素给人以更贵的感觉。除此之外,还具有集成数字键盘的功能,事实证明这是对键盘的有效补充。接口稳定可靠,尽管Wi-Fi 5并不是一个很大的卖点,但无线连接速度仍然是快速的。

ZenBook 14是一款外观精美的坚固笔记本电脑。不幸的是,它不能完全利用其CPU的性能。

但是,潜在的购买者不应将自己的选择局限于Ryzen 7 3700U型号,而可以自信地购买性能较弱的CPU型号。由于散热系统不能支持全部性能,因此长期性能远远低于我们为该处理器的期望。由于无法升级内存,因此在购买之前确定合适的型号时还需要考虑其内存大小。如果您最感兴趣的是设计和机身,而不一定是实际性能,那么您仍然可以毫不犹豫地购买这款笔记本电脑。
