惠普 ProBook 640 G3 (7200U, 全高清) 商务本简短评测

可圈可点。 惠普的14寸笔记本有着较长的电池续航时间,出色的输入体验,高速NVMe固态硬盘以及较低的系统噪音。但又一次,屏幕成为了它的缺点:惠普选择了一块低对比度,窄可视角度的面板。

Screen Flickering / PWM (Pulse-Width Modulation)

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 192 Hz ≤ 90 % brightness setting

The display backlight flickers at 192 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 192 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 18110 (minimum: 5 - maximum: 3846000) Hz was measured.

Display Response Times

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
30 ms ... rise ↗ and fall ↘ combined↗ 13 ms rise
↘ 17 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. » 77 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21.6 ms).
       Response Time 50% Grey to 80% Grey
41 ms ... rise ↗ and fall ↘ combined↗ 19 ms rise
↘ 22 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. » 59 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (33.9 ms).

In review: HP ProBook 640 G3 Z2W33ET. Test model provided by Notebooksbilliger.de

归功于Kaby Lake 处理器,ProBook提供了高性能体验。然而,相较于Skylake处理器的性能提升有限。这台笔记本在全负载时运行几乎没有噪声,温度控制也相对不错-对于办公设备来说是很好的优点。内置的NVMe 固态硬盘保障了流畅的系统操作以及快速的载入时间。想要更换固态硬盘也是很方便的,只需要打开笔记本的背壳,这个操作将会简单方便。

外壳和输入设备并没有变化,惠普沿用了上一代的设计。我们没有怨言因为两者都给我们留下了很好的印象。电池续航时间,和上一代一样,是十分出色的,足够一天的使用。LTE/HSPA+网络模块能够让你获得互联网链接或者是通过移动网络接入公司内网。 虽然惠普在这台笔记本上做了很多正确的事,但也有很多缺点能被列数。


我们的批评再一次落在了屏幕上。它的可视角度偏小,对比度偏低。这是令人无法接受的。超过1000欧元(约合1062美元)的价位应该有一块更好的屏幕。还有一点,在这个价位,键盘应该有背光。最后但同样重要的是,惠普只提供了一年的保修。
