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 | ||
|---|---|---|
| 24 ms ... rise ↗ and fall ↘ combined | ↗ 17.6 ms rise |  |
| ↘ 6.4 ms fall | ||
| The screen shows good response rates in our tests, but may be too slow for competitive gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 50 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.9 ms). | ||
| ↔ Response Time 50% Grey to 80% Grey | ||
| 43.2 ms ... rise ↗ and fall ↘ combined | ↗ 21.6 ms rise |  |
| ↘ 21.6 ms fall | ||
| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 69 % 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 | 200 Hz | ≤ 90 % brightness setting |  |
The display backlight flickers at 200 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 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 8702 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Pros
+ 坚固的机身
+ 光驱
+ 高品质输入设备
+ 明亮的全高清屏幕
+ 优秀的应用程序性能
+ 低发热量
+ 长电池续航
+ 集成LTE模组
Cons
- 相对笨重
- 风扇噪音
- TN面板的可视角度范围有限
- 接口布局不合理
尽管相比ProBook 640 G2还有更薄更雅致的办公笔记本电脑，但毫无疑问惠普在其他的方面都赋予了这台14寸设备优秀的品质。只有不多的几个竞争对手提供了光驱和VGA接口。不过，这也为它增加了额外的重量。相对的，ProBook也带来了无可挑剔的键盘、高应用程序性能以及长电池续航作为回报。生产商也应该为搭配了内置LTE模组和低发热得到我们的掌声。
遗憾的是，一些在细节上的缺点影响了之前提到的优秀整体表现。我们不太喜欢它不够合理的借口布局，吵闹的风扇，以及可视角度极窄的TN屏幕。
特别是后者，考虑到四位数的价码让人十分难以接受，而且其他的竞争对手大都提供了高品质的IPS屏幕（至少是可选升级）。很高的屏幕亮度对此也只能略作弥补。对这个缺点不太在意的消费者依然可以考虑这台设备，同样来自戴尔，联想或东芝的笔记本电脑也都不是完美无缺。
可以接受可视角度范围很窄的屏幕，笨重的机身的用户可以ProBook 640 G2这款十分全面的办公笔记本电脑。在竞争中它表现不俗，同时还有搭配光驱这个独特卖点。
