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. » 80 % 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)
Screen flickering / PWM detected | 199.2 Hz | ≤ 50 % brightness setting | |
The display backlight flickers at 199.2 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 50 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 199.2 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 8743 (minimum: 5 - maximum: 343500) Hz was measured. |

Pros
Cons
总的来说EliteBook 850 G4是难免令人沮丧。虽然惠普使用此设备配备了正确的配件,但仍然令人失望。外壳坚固而且制作精良,输入设备是不错(虽然不完美),散热出色,电池续航也非常好,考虑到电池容量。总而言之,除了雷电3的缺乏,难以维护和价格高之外,还没有太多的缺点。
不幸的是,所有这一切惠普传统上的高端商务本特质,都被劣质的TN显示屏幕所掩盖。毕竟,该机价格在稍微超过1400欧元(约合1491美元)的区间里,即使是在你以1700欧元(约1811美元)获取最高配置机,它的显示效果也是一样的。是的,屏幕是是明亮的,但除此之外,它显示了您可以从TN面板中预期的所有“质量”。笔记本电脑规格表中列出,在德国尚不能获得超高清IPS选项。
惠普采用了所有正确的配件......除了一个:EliteBook 850 G4的TN面板,它搞砸了原本可以非常好的印象。
但除这就是为什么尽管它的所有功能和质量都不错,我们还是不能推荐EliteBook 850 G4的原因。如果是在五年前,这是一个完全不同的情况:当时几乎所有的商业笔记本电脑配备了类似的显示器。然而,惠普似乎是唯一没有获得备忘录的人。如今,TN面板在价格相同的笔记本电脑中全部消失。其主要竞争对手在其高端业务设备中提供全高清IPS面板。 就连ThinkPad T570相当差劲的IPS面板都击败了EliteBook的劣质TN面板,更不用说其他高品质的IPS面板,例如富士通 Lifebook U757。
