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 8705 (minimum: 5 - maximum: 343500) Hz was measured. | ||

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 | ||

| 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. » 89 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.9 ms). | ||

Pros
+ 精致坚固的机身
+ 最新接口
+ 高速无线网络
+ 准确的输入设备
+ 优秀的应用程序性能
+ 低发热量
+ 无风扇
+ 三年质保
Cons
- 只提供了一个USB A型接口
- 自动亮度和对比度控制
- 有限的可升级空间
- 较高的售价
一块几乎无边框的屏幕，被动散热和Thunderbolt 3接口——戴尔Latitude 13 7370必然可以从一成不变的主流商务笔记本中脱颖而出。这台超极本不需要在便携性和品质上惧怕任何惊蛰对手，它的机身工艺无可挑剔，输入设备也十分可靠。酷睿m平台的性能表现也十分优秀：在BIOS更新之后，短时间负载下它的表现几乎可以与主动散热机型相媲美。它的频率和性能只有在持续负载下才会明显下降，不过这在日常办公中应该十分少见。
7370没能得到很好分数的主要原因是屏幕。戴尔为它搭配了一块背光明亮的不错屏幕面板，不过由于自动亮度和对比度控制无法一直处于高亮度下。这让人十分费解，我们希望可以通过更新得到解决。这样的话，只有它的高售价会成为我们难以向用户推荐的原因了：目前价位约2200欧元（约16056人民币），Latitude 13显然不算便宜——甚至（面相消费用户）Apple MacBook 12也还便宜几百欧元。
