Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 200 Hz | ≤ 20 % brightness setting |  |
The display backlight flickers at 200 Hz (worst case, e.g., 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: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8705 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Pros
Cons
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。
