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 ms ... rise ↗ and fall ↘ combined | ↗ 7.2 ms rise |  |
| ↘ 18.8 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. » 59 % 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 | ||
| 46 ms ... rise ↗ and fall ↘ combined | ↗ 19 ms rise |  |
| ↘ 27 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. » 76 % of all devices are better. This means that the measured response time is worse than 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 detected | 200 Hz |  | |
The display backlight flickers at 200 Hz (worst case, e.g., utilizing PWM) . The frequency of 200 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below. 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. | |||

Pros
+ 明亮，视角稳定的IPS屏幕
+ 被动散热的酷睿m5处理器
+ 不错的电池续航
+ 高速256GB固态硬盘
+ 全尺寸USB 3.0
+ 优秀的相机
Cons
- 处理器无法发挥全部潜能
- 12个月的标准质保
- 我们的测试机有些小瑕疵
- 仅一个USB 3.0C型接口
- 戴尔提供的配件相对较贵
戴尔的Latitude 11 5175是一台设计简洁的优良商务平板电脑。英特尔酷睿m5-6Y57处理器可以为日常办公提供足够的性能。低功耗让它可以使用被动散热。搭配的256 GB固态硬盘的优秀读取写入速度保证了系统运行的流畅。全高清触控屏幕提供了非常优秀的亮度，可以适合户外阳光下使用。它的触控功能响应准确迅速。同时，IPS屏幕面板的出色可视角度稳定性也让人无可挑剔。它的另外一个优势是优秀的电池续航时间，可以保证长时间的移动使用。
这台平板电脑是不错的入门商务设备。不过，如果想要得到最高的工作效率，用户无法避免需要考虑戴尔为11 5175设计的配件。键盘底座可以说是必不可少的额外消费。
戴尔Latitude 11 5175也有一些让我们难以满意的地方。它的处理器性能无法完全得到发挥。因此它的性能表现难免会打折扣。搭配酷睿m3的微软Surface Pro 4相比性能更高。它的屏幕由于色域覆盖一般也很难满足专业用户的需要。
感兴趣的用户可以参考我们列出的戴尔Latitude 11 5175的优缺点。可以接受色彩一般的1080p屏幕的用户完全可以把它加入收藏夹。同时它的处理器性能尽管受到了一定限制，仍然可以满足办公的需要。几乎没有任何一台平板电脑可以长时间持续利用酷睿m处理器的潜能。
