惠普 ProBook 650 G2 笔记本电脑（全高清）简短评测

Name: HP ProBook 650 G2 V1A44ET
Brand: HP

遗憾的屏幕。 惠普的这台中端商务笔记本电脑可以凭借不错的输入设备，坚固的机身，优秀的电池续航和低噪音得到不错的分数——不过它的全高清屏幕有些让人失望。我们期待一台超过1050欧元（约7844人民币）的笔记本电脑可以表现的更好。

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 8719 (minimum: 5 - maximum: 343500) Hz was measured.

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
27 ms ... rise ↗ and fall ↘ combined	↗ 10 ms rise
27 ms ... rise ↗ and fall ↘ combined	↘ 17 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 64 % 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
41 ms ... rise ↗ and fall ↘ combined	↗ 23 ms rise
41 ms ... rise ↗ and fall ↘ combined	↘ 18 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. » 61 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.8 ms).

In review: HP ProBook 650 G2. Test model courtesy of HP Germany.

惠普ProBook 650 G2是一台中端笔记本电脑，对于大部分日常用途它都可以提供足够的运算性能。这台笔记本运行安静，几乎不会变热。一块高速固态硬盘带来了流畅的系统运行，用户可以自行打开笔记本电脑底盖更换，实际操作并不复杂。它搭配的键盘可以让人满意，不过没有背光，对ProBook来说这也应该成为标准配置才对。它的电池续航十分不错。
