HP Elite Dragonfly Business-Convertible笔记本电脑：这台惠普的翻转本令我们印象深刻

真正的Elitebook。 惠普推出了重量不到1千克的Elite Dragonfly翻转本。 但是，轻型商务翻转本是否真的是功能完善的EliteBook，还是就是个办公桌上的摆设？ 我们评测了更大的4芯电池版本，将重量增加到超过1.1千克。

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
33.8 ms ... rise ↗ and fall ↘ combined↗ 17.2 ms rise
↘ 16.6 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. » 89 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21.5 ms).
   ↔    Response Time 50% Grey to 80% Grey
60.8 ms ... rise ↗ and fall ↘ combined↗ 30.8 ms rise
↘ 30 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 96 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (33.7 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 17900 (minimum: 5 - maximum: 3846000) Hz was measured.

In Review: HP Elite Dragonfly. Test model courtesy of MyNotebook.de

Elite Dragonfly是真正的EliteBook吗？经过全面审查，我们可以肯定的回答“是”。您将获得高质量，坚固的机身，全面的安全功能以及熟悉的服务选项，包括备件的长期可用性。从出色的输入设备， LTE的快速通信模块和较长的续航时间来看，HP的高级二合一还可以在许多其他方面说服买家。但是，后者是为带有较大电池的型号保留的，这将重量增加到超过1千克。不过，我们认为这是一个很好的妥协。

接口方面也没有太多批评，因为除了USB-C连接器之外，您还获得了常规的USB A型端口以及全尺寸HDMI输出。我们仍然认为，有两种方法可以优化端口状况：布局（USB-C朝后，理想的情况是在两侧）和SD读取器，至少能支持microSD卡。

HP Elite Dragonfly是一款非常出色的商务二合一。肯定有一些缺点，但是它们并不是特别要紧。因此，如果您正在寻找商务二合一，我们建议购买Elite Dragonfly。

还有其他缺点，包括处理器的TDP配置非常保守。几秒钟后，性能就会降低，但这仍然足以满足一般的办公任务。如果您需要大量的CPU性能，则应该考虑更好的设备。尽管我们认为风扇对负载的反应过快，但风扇却非常安静。

我们的建议主要考虑使用Core i5，标准1080p触摸屏和更大电池的配置。您可以使用较小的电池减轻重量，但我们希望在此类移动设备上使用更长的续航时间。这也是可选4K屏幕的问题，因为它将消耗更多电量。我们对标准的1080p触摸屏也很满意，只有响应时间慢（您会习惯的）和反光才是缺点。
