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 | ||
|---|---|---|
| 37 ms ... rise ↗ and fall ↘ combined | ↗ 20 ms rise |  |
| ↘ 17 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. » 95 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.3 ms). | ||

| 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. » 52 % 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 8163 (minimum: 5 - maximum: 343500) Hz was measured. | ||

Pros
+ 众多可选机型
+ 实惠（附加折扣）
+ 设计合理的机身
+ 屏幕无闪烁
+ 支持TPM
+ 附带恢复盘
+ 易于维护升级
+ 不错的输入设备
+ 固态硬盘
+ 非常安静且发热量低
+ 超长电池续航（65瓦时电池尺寸略大）
Cons
- 无法一只手打开屏幕上盖
- 仅一年质保
- 屏幕亮度和像素密度过低
- 黑值过高，对比度低
- 可视角度范围小
- 色彩还原差
- 屏幕过暗不适合户外使用
- 音响效果差
依然在销售中的戴尔Latitude 15-3570，特别是它的入门机型，性价比非常高。起售价419欧元（约3098人民币），它的优秀机身和不错输入设备都让人无可挑剔。不过，我们的测试机在屏幕和音响系统上弱点明显，因此多媒体爱好者应该另谋他就。另一方面，它的技术参数，安静清凉的运行都给了我们很深的印象。如果从机身突出的电池是个问题的话，用户可以选择48瓦时的电池。对安全功能比较重视的用户也会很满意它对TPM和可选指纹识别器的支持。
我们所测试的3570机型由于搭配了固态硬盘在使用流畅性上相比竞争对手优势明显。不过，它的屏幕无法让人满意，特别是较低的分辨率。
