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
26.4 ms ... rise ↗ and fall ↘ combined	↗ 15.6 ms rise
26.4 ms ... rise ↗ and fall ↘ combined	↘ 10.8 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. » 62 % 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
36 ms ... rise ↗ and fall ↘ combined	↗ 17.2 ms rise
36 ms ... rise ↗ and fall ↘ combined	↘ 18.8 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. » 46 % of all devices are better. This means that the measured response time is similar to 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 8774 (minimum: 5 - maximum: 343500) Hz was measured.

In review: Fujitsu Lifebook U757. Review sample courtesy of Fujitsu Germany.

我们所评测的这两个新的Lifebook U笔记本非常相似。U757在某种程度上可以说是U747 的一个尺寸更大的版本，因此它继承了原本型号的优缺点：良好的屏幕，舒适的键盘，优秀的外壳。触摸板变化很大。U757的风扇噪音对比尺寸较小的型号有所优化，但同时也可能会产生来自固态硬盘的噪声。

与较小型号相比，U757最大的缺点在于，富士通并没有真正利用这个机会让15英寸机型独特化，没有有效地利用更大尺寸带来的优势。数字键盘，一个可选的2.5英寸机械硬盘/固态硬盘插槽，另外一个HDMI接口和一个可选的（目前没有安装在任何德国机型上）的UHD屏幕：这些是U757与U747的差别。其实，在其他方面也可以做出改变：例如，对于15英寸商用笔记本电脑来说，两个USB Type-A接口相当薄弱，50瓦时的电池相对较小（与较小型号相同），鉴于拥有额外的空间，一个可以安装到U757中的专用显卡也应该被配备。然而，这也没有。

U757与其较小的原有机型没有做够的差异性。所以如果要在富士通的U系列中Lifebook中做选择时，我们推荐较小型号。其尺寸在日常使用中更加让人愉快。

因此，U757可以说是U747的加大版本。如果觉得LifeBook U系列的硬件条件有吸引力，买家应该选择U747. 更大的机型只的优势在于当需要数字小键盘和更大的屏幕。可选的超高清机型目前无法在德国获取。这个类别下，有一些设备也很有趣;特别是 ThinkPad T570 ，并且可能是一个强劲的对手。惠普Elitebook 850 G4 也是一个很好的竞争对手。
