Business Laptop / Notebook Skylake Windows

均衡。 华硕带来了一台设计优良的14寸TravelMate,与来自惠普、戴尔和联想的设备相竞争。这台TravelMate在外观上与前代机型相同。不过,生产商为它搭配了最新硬件:Skylake,DDR4和Thunderbolt 3接口。百尺竿头更进一步,它值得称道的一大优点是出色的电池续航时间。

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: 50 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17109 (minimum: 5 - maximum: 2500000) Hz was measured.

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
25 ms ... rise ↗ and fall ↘ combined↗ 7 ms rise
↘ 18 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. » 41 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (24.9 ms).
       Response Time 50% Grey to 80% Grey
44 ms ... rise ↗ and fall ↘ combined↗ 16 ms rise
↘ 28 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. » 63 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (39.5 ms).

Acer带来了一台优秀的14寸商务笔记本电脑TravelMate P648-M。它搭配的处理器提供了可以满足大多数应用所需的性能。这台笔记本电脑同时运行安静,也不会变得很烫。告诉的固态硬盘保证了迅捷的系统响应。用户可以方便地打开底盖自行更换升级固态硬盘。归功于内置的LTE模组,你可以通过移动网络连接互联网。它也支持通过机身底部的接口连接Acer拓展坞,带来更多的接口。这台笔记本电脑搭配了优秀的输入设备,同时提供了出色的电池续航。这台TravelMate的IPS屏幕可视角度宽广且对比度高,不过它的亮度有些过低。我们期待这个价位的笔记本电脑能够搭配更好的屏幕。
