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 200 Hz ≤ 20 % brightness setting

The display backlight flickers at 200 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 200 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9665 (minimum: 5 - maximum: 151500) 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
27 ms ... rise ↗ and fall ↘ combined↗ 17 ms rise
↘ 10 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. » 55 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.2 ms).
       Response Time 50% Grey to 80% Grey
43 ms ... rise ↗ and fall ↘ combined↗ 20 ms rise
↘ 23 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 636 (maximum) ms. » 60 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (38.4 ms).

戴尔Latitude 14 7414 Rugged Extreme是一款为特殊作业情况而设计的14寸笔记本电脑。它可以保护内部免受灰尘,液体,液滴和热量的影响。与前代相比,它的外观没有变化。改变只能从内在观察到,Skylake升级为Haswell,从而提高了机器的处理能力。随着性能的提高,噪声水平和热量排放没有增加。该机始终保持运行时的安静。更重要的是,电池续航能力优秀。

Latitude 14 7414适用于恶劣环境。

固态硬盘可以保证系统的高速运行。为该机更换固态硬盘,不需要花费太多力气。我们已经熟悉了该笔记本电脑前代的背光键盘。它提供了舒适的打字体验。显示器保持与配备Haswell的前代相同的亮度,高对比度,可视角度。戴尔拒绝从提供端口选择方面的升级,雷电3,DisplayPort或Type-C USB甚至都不能作为选项提供。
