Display Response Times

ℹ

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
27 ms ... rise ↗ and fall ↘ combined	↗ 16 ms rise
27 ms ... rise ↗ and fall ↘ combined	↘ 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 0.1 (minimum) to 240 (maximum) ms. » 64 % 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
38 ms ... rise ↗ and fall ↘ combined	↗ 19 ms rise
38 ms ... rise ↗ and fall ↘ combined	↘ 19 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. » 51 % 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)

ℹ

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 8743 (minimum: 5 - maximum: 343500) Hz was measured.

The Acer Chromebook 14, provided by notebooksbilliger.de

“工作用Chromebook。”这是宏碁对于他们新的Chromebook的看法：一台日常用办公设备。第一眼看上去就只要Chromebook有了很大的进步。它采用高亮钢琴烤漆取代了原本外壳花哨的颜色。糟糕的是它很容易吸附指纹。但对于一台工作用设备来说，更加重要的是输入设备的适应性。键盘能够很好的应对在办公室的长时间工作。但对于一台完整的商务设备来说，它还缺少很多的安全功能。

雾面IPS屏整体上来说还是很好的。色彩及灰阶的表现都不错。但是，这块屏幕的俩都不足。办公室中或户外的阳光直射都会对于操作造成很大的影响甚至是彻底无法操作。

其搭载的硬件引起了我们的注意。但是，它无法发挥其完整的性能，甚至在基准测试中被更弱的酷睿m5处理器超越。不过，系统的运行还是十分流畅的，比其他一些Chromebook运行的都要快。

宏碁 Chromebook 因为其出色的发热控制和9小时的电池续航时间而赢得了不错的评分。
