戴尔 Latitude 5480 (7600U, FHD) 笔记本电脑简短评测

Name: Dell Latitude 5480
Brand: Dell

强力中端机。 戴尔的这台14寸商务机型Latitude 5480设计低调，支持多种安全功能和丰富可选配置。它最大的优势明显是在于超长的续航时间，不过类似前代机型它的屏幕亮度仍然是个短板。

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
26.4 ms ... rise ↗ and fall ↘ combined	↗ 5.2 ms rise
26.4 ms ... rise ↗ and fall ↘ combined	↘ 21.2 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. » 62 % 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
32.8 ms ... rise ↗ and fall ↘ combined	↗ 14 ms rise
32.8 ms ... rise ↗ and fall ↘ combined	↘ 18.8 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. » 40 % of all devices are better. This means that the measured response time is similar to 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 not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8743 (minimum: 5 - maximum: 343500) Hz was measured.

In review: Dell Latitude 5480. Test model provided by Dell US

在外观上，它没有什么变化：戴尔的14寸Latitude 5480延续了前代机型Latitude 14 E5470的低调设计和流畅黑色外壳。高端Kaby Lake架构i7双核处理器为大部分商务应用提供了充足的性能。集成显卡的3D性能只是一般般；需要更强图形处理性能的用户需要选择搭配英伟达GeForce 930MX显卡的Latitude机型。它的机身品质也十分出色，接缝均匀紧凑，不过我们不太喜欢它较为脆弱的键盘中间区域。它的输入设备，包括触控屏幕，都十分优秀，它的键盘使用感受也十分不错。但是习惯了ThinkPad指点杆的用户可能不会太喜欢它的鼠标按键设计。

它的一个主要改变，在我们看来是一大退步的是新的屏幕面板。尽管它带来了更高的对比度和色域覆盖，但是它的亮度却低了35%。不过好消息是，它的电池续航有了长足的进步，现在可以轻松领先同类设备且优势不小。
