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 | ||
|---|---|---|
| 33 ms ... rise ↗ and fall ↘ combined | ↗ 19 ms rise |  |
| ↘ 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. » 88 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.9 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. » 68 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.8 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 | 1020 Hz |  | |
| ≤ 90 cd/m² brightness | |||
The display backlight flickers at 1020 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 90 cd/m² and below. There should be no flickering or PWM above this brightness setting. The frequency of 1020 Hz is quite high, so most users sensitive to PWM should not notice any flickering. Flickering occurs at relatively low brightness settings, so extended use at this brightness setting or lower can cause eyestrain. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8715 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Pros
+ 可选Thunderbolt
+ 出色的输入设备
+ 3个储存设备槽位，支持NVMe
+ MIL STD 810G认证外壳
+ 高速SD卡读卡器
+ 价格不错
Cons
- 屏幕亮度中庸
- 风扇一直很吵
- 性能相比起i5-7200u的版本来说并没有提升
- 无 E-Port (扩展坞用)
乍看起来，这台Latitude 5580和我们已经测试过的那台没有什么不一样。但事实上全高清屏幕产生了很大的不同且使得整个配置更加完备。我们在上次的评测中就对它出色的输入体验赞许有加，它很合适在工作或是在家中的长时间打字操作。戴尔Latitude 5580特别为了商业市场提供了一些重要的安全功能。
配置中的处理器升级说不上是成功。我们的基准测试并没有发现明显的性能提升。它甚至导致续航时间减少了一小时。
戴尔 Latitude 是一台可靠的笔记本，无论是作为一台商务本还是日常用办公本。
但是，消费者也应该考虑一下联想ThinkPad T470s，它有着更快的固态硬盘而且在我们的基准测试中表现得更好。
