Screen Flickering / PWM (Pulse-Width Modulation)
| 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 17933 (minimum: 5 - maximum: 3846000) Hz was measured. | |||

Pros
Cons
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。
惠普的ProBook 650 G2在定位上有些模糊不清，因为它和ProBook 450系列的差价很小，不过由于定位更高它也应该有更好的表现。
对于它搭配的全高清屏幕我们很难满意。它的对比度较低，可视角度也较窄，色彩准确度也不够优秀，同时色域覆盖十分窄。这样的屏幕在这个价位上显得十分让人难以理解，另一方面也很难达到惠普对ProBook 650系列所宣传的水准。
