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
30.4 ms ... rise ↗ and fall ↘ combined	↗ 16.4 ms rise
30.4 ms ... rise ↗ and fall ↘ combined	↘ 14 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 82 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.3 ms).
↔ Response Time 50% Grey to 80% Grey
40 ms ... rise ↗ and fall ↘ combined	↗ 18.8 ms rise
40 ms ... rise ↗ and fall ↘ combined	↘ 21.2 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. » 60 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (31.7 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 8167 (minimum: 5 - maximum: 343500) Hz was measured.

The Dell Latitude 3189: test unit provided by Dell Germany.

戴尔主要将Latitude 3189定位在教育领域。这么说的依据是其结实的设计。如良好的触摸屏等额外的功能给这台设备增加了附加价值。这也使得这台设备多用途化。英特尔奔腾N4200处理器，4GB大小的DDR3 RAM，这是厂商在性能方面提供最强选项。我们不会推荐选配英特尔赛扬N335理器的型号。我们的测试型号运行的非常不错，尽管它最低要价799欧元(约合870美元)。但是，配以英特尔赛扬3350（双核处理器）的设备型号，性能相较而言明显下降。

戴尔Latitude 3189是一台非常坚固的设备，这能够帮助孩子学习如何使用新媒体。有着稳固基础的设备能够执行很多任务，并且由于它出色的电池续航时间，一次充电能够轻松的坚持一整天的学校使用。

我们对戴尔Latitude 3189也有一些不满的地方：例如，缺失的USB Type-C型接口，这将保障这台设备的未来使用，高反射的显示屏，这让人不舒服同时难以在光亮环境中设备既有优点也有缺点。安装完操作系统和一些程序之后，128GB的存储空间所剩无几。总体来说，尽管在我们的部分测试项目中这台设备发挥的不是很好，但是我们觉得戴尔 Latitude 3189总体表现不错。从主观来看，这台设备的性能比跑分结果要强得多。
