惠普 ProBook 440 G4 (酷睿i7, 全高清) 笔记本电脑简短评测

Name: HP ProBook 440 G4-Y8B51EA
Brand: HP

很差的显示效果。 惠普14英寸商务笔记本电脑也获得了Kaby Lake处理器的更新。然而，与更大的15英寸同系列产品一样，屏幕未能说服我们。

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
24.4 ms ... rise ↗ and fall ↘ combined	↗ 7.2 ms rise
24.4 ms ... rise ↗ and fall ↘ combined	↘ 17.2 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. » 53 % 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
43.2 ms ... rise ↗ and fall ↘ combined	↗ 21.2 ms rise
43.2 ms ... rise ↗ and fall ↘ combined	↘ 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 0.165 (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 (32.9 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 8746 (minimum: 5 - maximum: 343500) Hz was measured.

In review: HP ProBook 440 G4. Test model courtesy of HP Germany.

惠普ProBook 440 G4非常类似于它的兄弟姐妹，其中包括优缺点。它是一个入门级的商用设备，所以你必须忍受一些妥协。这包括一些功能的缺失，如SmartCard读卡器或对接端口。在外壳质量和端口种类上，ProBook也落后于更昂贵的产品，例如惠普自家的EliteBooks。

然而，ProBook 440 G4的最大的问题是屏幕。我们的测试机已经配备了你所能获得的这个机型的“最好”屏幕，但我们仍然感到失望。我们不明白为什么惠普甚至不提供IPS面板作为选择。在过去，我们也评测了更好的TN面板。

惠普 ProBook 440 G4速度快，提供良好机身和舒适键盘，但显示器难以匹配超过1000欧元（约1074美元）的价格。

更新后的ProBook 440 G4的性能并不令人失望，益于快速处理器和固态硬盘，系统可以处理许多应用程序。另一个问题是：是否可以从专用的图形处理器中获益。它显然比集成显卡更强大，但这是主要体现在你玩游戏时。如果你想节省一些钱，你一定可以选择一个有酷睿 i5和集成显卡的产品。由于令人失望的显示效果，我们仍然很难推荐的14英寸版本的ProBook给所有用户。
