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: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 18100 (minimum: 5 - maximum: 3846000) 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↗ 10 ms rise
↘ 17 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. » 63 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21.6 ms).
       Response Time 50% Grey to 80% Grey
47 ms ... rise ↗ and fall ↘ combined↗ 22 ms rise
↘ 25 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 78 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (33.9 ms).

In review: Dell Latitude 15 E5570. Test model courtesy of Notebooksbilliger.

戴尔Latitude 15 E5570是一台搭配15.6寸屏幕的纯粹商务笔记本电脑。它的设计相比前代机型变化很小,但内部配置则大有改观。Skylake架构超低电压处理器为日常应用提供了充足的动力。如果你需要更高的性能,可以考虑选择搭配酷睿i5四核处理器的机型。这台设备十分安静,几乎不会变烫。一块固态硬盘让系统响应迅速,你也可以进一步升级它。这需要打开底盖,不过并不繁琐。与现代机型相似的是,它的键盘十分易用,电池续航时间也十分优秀。

来自戴尔的这台Latitude在很多方面都非常实用,不过也有一些缺点。

这台设备提供了常见的商务功能如指纹识别器,扩展坞接口,智能卡读卡器(可选),不过戴尔去掉了它对TPM的支持,改而搭配了ControlVault技术。它的屏幕可能也不会让任何人惊喜。戴尔为它搭配了一块低对比度的昏暗屏幕,可视角度范围也十分有限。我们期待一台售价达1000欧元(约7343人民币)的设备能够有更好的屏幕,同时作为Latitude也应该支持USB-C型接口。
