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
23.2 ms ... rise ↗ and fall ↘ combined↗ 12.4 ms rise
↘ 10.8 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 33 % 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
36 ms ... rise ↗ and fall ↘ combined↗ 16.4 ms rise
↘ 19.6 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. » 30 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (39.5 ms).

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.

Lifebook U747是一台优秀的笔记本。富士通并没有犯很多的错误。它拥有出色的屏幕,优秀的电池续航时间,以及一块能够提供舒适打字体验的键盘。外壳设计坚固且制造质量出色,而且它的设计符合它的商务定位。这也可以说是有关于其接口的多样性。尽管确实缺失Thunderbolt 3接口,但这在近期更像是一个附加项缺乏也并不会成为缺点。评测样机的温度保持在较低水平,风扇也通常仅是待机。

我们来到了缺点部分:尽管风扇相对安静,但一旦开始工作便会产生高频噪音。这的确不是一个大问题,但是很烦人。同样的情况发生在扬声器和内置摄像头上。但是这两个部分通常都会被忽略。最大的缺点在于其鼠标替代品的选择:富士通并没有选择一块Precision触控板,这使得它显得有点过时,因此触摸板也不够好。不幸的是,触摸板的按键反馈也十分劣质而不准确。而Lifebook并没有配备用于代替触控板的指点杆。最后,保修时间相对于竞品来说也有些偏短。

富士通的Lifebook U747是商务市场中的有利竞品。但不幸的是,糟糕的触摸板毁了其对于商务人士的好印象。

除去触摸板,Lifebook整体上令人满意且值得推荐。但竞争激烈的市场并没有留给富士通一条好路。一款强有力的竞品联想 ThinkPad T470 在很多方面都比富士通得到了更高的分数,只有屏幕是其显著的弱点。戴尔的新Latitude和惠普的新EliteBook 型号(Latitude 7480 和 EliteBook 840 G4)也将肯定成为强力的竞争者。对应的评测将会在近日放出。
