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
30 ms ... rise ↗ and fall ↘ combined	↗ 10 ms rise
30 ms ... rise ↗ and fall ↘ combined	↘ 20 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. » 78 % 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
51 ms ... rise ↗ and fall ↘ combined	↗ 23 ms rise
51 ms ... rise ↗ and fall ↘ combined	↘ 28 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. » 86 % 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 detected

50 Hz

≤ 40 % brightness setting

The display backlight flickers at 50 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 40 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 50 Hz is very low, so the flickering may cause eyestrain and headaches after extended use.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8774 (minimum: 5 - maximum: 343500) Hz was measured.

Pros

+ 准确的触控版

+ 不错的性能表现

- 无指点杆

ProBook 450 G4是一台十分不错的设备：它的机身品质可靠没有什么缺点，金属掌托质感舒适，同时它也提供了十分丰富全面的接口，甚至包括USB-C。尽管这个接口相比普通USB没有提供更多支持，但可以满足一部分未来设备所需。它搭配的处理器提供了不错的性能，键盘输入体验舒适，而触控版的响应也准确迅速。最后，它的电池提供了不错的续航，让用户可以不为出门在外办公担心。

遗憾的是，这些并不能掩盖这台设备的最大缺陷：惨淡的屏幕。如果售价600欧元（约4355人民币）的话这可能还可以忍受，但在1000欧元（约7258人民币）的价位上就无法让人妥协了。同时它还有一些别的不足：指纹识别器不太可靠，同时处理器的温度在负载下较高。惠普应该允许风扇速度运转更快一些。

十分遗憾，生产商对这块与价位好不相称的屏幕的选择破坏了本可以无懈可击的这台设备。

在处理性能上ProBook依然可以独步商务设备市场。不过这也会在不久后有所改变：ThinkPad E570 已经发布，它搭配IPS屏幕和GeForce 950M，会是一台十分引人注目的设备。其他的厂商可能会在2017年初跟上机型更新的步伐。
