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. » 91 % 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)
Screen flickering / PWM detected | 200 Hz | ≤ 90 % brightness setting | |
The display backlight flickers at 200 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 90 % 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 8774 (minimum: 5 - maximum: 343500) Hz was measured. |

Pros
Cons
作为较低价的富士通LifeBook A557在市场上非常有吸引力。这款15.6英寸笔记本电脑主要以稳健的系统性能为基础,这将巩固其作为办公系统的部署。到目前为止,英特尔酷睿i5-7200U已经成为一个通用的处理器,能够承担更复杂的任务。拥有8 GB的运行内存,系统配件精良。如果这还不够,那么可以毫无困难地进行升级,因为富士通LifeBook A557的易于维护。512 GB固态硬盘提供了大量的存储空间,并为系统顺畅运行提供了保障。
富士通LifeBook A557在低预算情况下提供了不俗的表现。那些对外观设计不看重的人会喜欢富士通LifeBook A557。
富士通LifeBook A557找不到多少缺点。在视觉上,我们的测试机相当不给力,未来制造商可以它改善噪声污染。同时,我们也希望有一个可选的背光键盘。当然,该机价格为649欧元(约682美元),我们应该接受这个让步。此外,显示器仅提供有限的颜色空间覆盖,尽管其可视角度是令人信服的。富士通LifeBook A557的低功耗也给人留下了积极的印象,从而保证了电池的使用时间。
